    The author describes a joint program to use renewables for rural electrification projects in Chile. The initial focus was in a limited part of the country, involving wind mapping, pilot project planning, training, and development of methodologies for comparative evaluations of resources. To this point three wind hybrid systems have been installed in one region, as a part of the regional private utility, and three additional projects are being designed. Additional resource assessment and training is ongoing. The author points out the difficulties in working with utilities, the importance of signed documentation, and the need to look at these programs as long term because of the time involved in introducing such new technologies.

    Smith, D V

    1980-03-01

    Decentralized power generation using renewable energy resources is more appropriate to the energy needs of the rural Third World. These countries often look to the rural electrification programs of the US and Soviet Union as the answer to their problem even though studies consistently show this to be inefficient and frequently ineffective, often reinforcing existing social and economic inequities. When the uses of energy in rural villages are examined in detail, the only approach which will supply energy to the rural poor must be based on a local and regional match of need to indigenous energy sources and to the development of local talent and enthusiasm. 29 references.

    One of the obstacles in rural electrification is choosing the type of the electric source which best fits rural areas technically, socially, and economically. Renewable sources can be used to electrify rural areas. Rural electrification in Libya by photovoltaic systems in a national program which is devoted to electrify isolated villages, as part of this program the installation of 300 systems was started at the beginning of the year 2003 with a total power of 400 K Wp, the sizes of stand alone systems are 1.8 K Wp, 1.2 K Wp, 0.75 K Wp, and 0.15 K Wp, beside a hybrid system of diesel and PV. The systems was designed to supply different family needs a total of 5000 inhabitants will benefit from this project. In this paper we will introduce the rural photovoltaic electrification in Libya program, company the performance of three different PV sizes through the first two years of working. The systems performing well and with performance ratio much more than the deigned, very little power failure was reported, and there are social and technical issues to be addressed before, and after the installation of the PV system.(Author)

    2001-01-01

    The majority of people living in developing countries do not have access to electricity and most of these two billion people live in rural areas. Social and political pressure to supply power to these areas will increase and the question will not be whether these areas will get electricity, but when. This book contains a comprehensive analysis of rural electrification programmes implemented in both industrialised and developing countries. The impact of current developments and trends on the approach to rural electricity supply in these countries is also examined. The author has identified a number of critical success factors for rural electrification, such as a politically and socially stable environment, an appropriate electrification process, support from the international community, and a utility organisation based on decentralisation and operational autonomy. The broad handling of the subject makes this book useful to utility managers, development agencies, academics, and others involved in the electrification of rural and remote areas refs

    2006-01-01

    Some of the problems that have besieged rural electrification in most developing countries include inadequate policies, weak institutional frameworks and limited financing. In the last two decades, governments in developing countries have been making various efforts both at the policy level and in financing to facilitate increased levels of rural electrification. However, the introduction of market-based reforms in the power sector in the last decade has affected the institutional and financing arrangements for rural electrification. The reforms have also affected the rate of electrification and affordability of electricity. There is need therefore to establish the extent to which the reforms have affected access and affordability of electricity in rural areas and to develop appropriate policy and the supporting institutional structures to align rural electrification with reformed power sectors. It is cardinal to establish how privatised and commercialised power companies in a reformed power sector could contribute to rural electrification and the role of governments and government agents in facilitating expanded access to electricity in rural areas

  17. The value of cooperatives in rural electrification

    International Nuclear Information System (INIS)

    Yadoo, Annabel; Cruickshank, Heather

    2010-01-01

    The electricity sectors of many developing countries underwent substantial reforms during the 1980s and 1990s, driven by global agendas of privatization and liberalization. However, rural electrification offered little by way of market incentives for profit-seeking private companies and was often neglected. As a consequence, delivery models for rural electrification need to change. This paper will review the experiences of various rural electrification delivery models that have been established in developing countries, including concessionary models, dealership approaches and the strengthening of small and medium-sized energy businesses. It will use examples from the USA, Bangladesh and Nepal, together with a detailed case study of a Nepali rural electric cooperative, to explore the role that local cooperatives can play in extending electricity access. It is shown that although there is no magic bullet solution to deliver rural electrification, if offered appropriate financial and institutional support, socially orientated cooperative businesses can be a willing, efficient and effective means of extending and managing rural electricity services. It is expected that this paper will be of particular value to policy-makers, donors, project planners and implementers currently working in the field of rural electrification.

    This paper addresses the issue of rural electrification from renewable energy. A brief introduction on biomass and wind electrical systems is given. The aim of this research is to propose optimal electrification system design for rural areas. This requires suitable generators selection as a starting point. Some generator types for rural electrification systems are introduced, followed by a discussion on the selection criteria. Simulation results of a typical electrification system for remote areas are obtained to support the safety aspect related to the individual generator types, in the event of accidental rotor motion. All simulations are done in Matlab-Simulink.

    The status of decentralized rural electrification in Vanuatu was presented. Vanuatu is a sparsely populated rural country in the south Pacific. The country includes 92 populated islands spread over 1,000 kilometers in the south Pacific, halfway between Fiji and Australia. The low population density and the tremendous distances between the different islands have made local electrical networks a necessity in Vanuatu. Apart from the two principal urban centres, Vanuatu does not have a centralized electrical distribution network. In the early 1990s the government initiated a program to provide independent power sources to the isolated communities. Photovoltaic cells are used to power most telecommunications services. Solar cells are also used to provide power to important community buildings such as the schools or nursing stations on the remote islands. Two small hydroelectric generating stations of 600 kW were also installed with the help of the German government

    Rural electrification is a political matter. Sometimes it is discussed as a social matter, sometimes as an economical matter, sometimes as a technical matter. The political aspect of the decisions is remarkable in all three fields.The present work relies on the concept that poorer producers will only be reached by a rural electrification program, if an alternative technology is used aiming to obtain low cost per connection. The ordinary distribution has a cost which doesn't reach those people. The work shows that target is denied in three moments by ideological reason. In a first moment it is denied by state economical politics, always neglecting giving assistance to poorer producers. In a second moment, it is denied by the utility which claims to have more urging problems to solve. Finally, it is denied by the engineer of distribution who, ideologically, turns to an engineering of primacy, and doesn't o think about the use of a more simplified technology. Actions to intended to interrupt these mechanisms are mentioned. One of the actions aims to introduce in the preparatory studies of engineers deeper discussions concerning the social function of energy. The other action is the proposition of a standard of rural electrification with leads to the solution of the problem, since there is political attention. (author)

    2012-01-01

    Given the fact that 1.4 billion people, over 20% of the world’s population, lack access to electricity, rural electrification remains a common challenge for many developing countries. The ‘Township Electrification Program’ launched by the Chinese government in 2002 is known as the world’s largest renewable energy-based rural electrification program in terms of investment volume ever carried out by a country. This study gives an in-depth examination of the program implemented in two selected townships in remote of rural areas of western China. The results showed that the implementation of the program possessed a technical orientation (e.g., construction of stations, installation of systems), and underestimated the financial implications (e.g., electricity tariff, households’ ability to pay electricity fees, financial management) as well as human resources available (e.g., training for operators, household participation) and institutional capacity building (e.g., good governance, regulatory framework) at the local level. Even though electricity was provided by the solar PV power stations, households still relied on traditional energy sources, such as candles and dry cell batteries, due to the fact that electricity service was unreliable and electricity supply was not sufficient for households’ needs. - Highlights: ► China’s electrification rate has reached the level of OECD countries. ► Township Electrification Program is the world’s largest electrification program. ► The program possessed a technical orientation and underestimated other aspects. ► Households still relied on traditional energy, such as candles and batteries. ► Having electricity access did not mean that electricity was actually used.

    The Philippines has pushed rural electrification for two decades. Recently, the government achieved 100% electrification at the village level. Despite the significant recent economic growth, poverty has increased in some areas. These are usually agricultural and have many un-electrified areas. The multilaterals have launched programs that couple electricity with livelihood projects. The authors argue this is insufficient to guarantee sustainability. A systems view of rural poverty suggests that several components must be designed to work together. In addition to the electricity and livelihood, skills, attitudes, management and markets must be incorporated to make a lasting impact on poverty.

    Full Text Available In 2014, the Indonesian government has targets to obtain 80% of electrification ratio and 98.9% of rural electrification ratio. Extending the grid and off-grid connection has been done to obtain the targets. This paper aims to compare two main programs on rural electrification namely Super Extra Energy Saving (Super Ekstra Hemat Energi, SEHEN that is belong to PLN (state owned company in electricity and the Solar Home System (SHS that is financed by the Ministry of Energy and Mineral Resources (MEMR. Indonesia has started the rural electrification program in the late 1950s, but how to provide electricity in a sustainable ways both organizationally and institutionally still become a big challenge. The experiences from East Nusa Tenggara provinces showed that both SEHEN and SHS can instantly improve electrification ratio, but government needs to synchronize the technical, administrative, and financial aspect from the two programs. Without any improvements in designing the program, we argue that the existing program is not sustainable.

    2016-06-01

    Full Text Available In Sub-Saharan Africa, 600 million people live without electricity. Despite ambitions of governments and donors to invest in rural electrification, decisions about how to extend electricity access are being made in the absence of rigorous evidence. In this paper, we present high-resolution spatial data on electrification rates in rural Kenya in order to quantify and visualize energy poverty in a novel way. Using our dataset of 20,000 geo-tagged structures in Western Kenya, we provide descriptive evidence that electrification rates remain very low despite significant investments in nearby grid infrastructure. This pattern holds across time and for both poor and relatively well-off households and businesses. We argue that if governments wish to leverage existing infrastructure and economies of scale, subsidies and new approaches to financing connections are necessary.

    The use of renewable energy technologies in China is becoming increasingly important to meet the needs of a large rural population. Solar and wind renewable resources in particular are available in regions of China that at present have no access to conventional grid power. Two regions in China that have an acute lack of electricity are a large region in northern and western China and the coastal island region of China. These regions have attracted the attention of the Chinese government in terms of increasing the quality of life and standard of living conditions of the rural population. These regions have also attracted the attention of domestic Chinese companies and of international companies, governments, and multilateral development organizations as a potential market for renewable energy rural electrification systems. This paper focuses on the bilateral cooperation between the US Department of Energy and China in providing assistance for the use of renewable technologies for rural electrification in northwestern China.

Aiming to improve this situation, the country conducted several electrification efforts in the last few decades that included off-grid photovoltaic (PV solutions for remote areas (where the grid expansion was unviable. More recently, the government has also sponsored a ‘massive program’ that aims to deploy a minimum of 150,000 off-grid PV solutions in the upcoming years. In this paper, we assess the sustainability of rural electrification programs in Peru, paying special attention to the ongoing “massive program”. Our assessment considers four dimensions of sustainability (institutional, economic, environmental, and socio-cultural and is based on an exhaustive qualitative document analysis complemented by semi-structured expert interviews. We found that the lack of strong formal institutions with a flexible and decentralized structure seriously compromises the sustainability of rural electrification efforts in Peru. Staff rotation and overlapping competences have caused disturbing changes and inhibited following a strategic line, while widespread outsourcing combined with weak controls have often affected the reliability of the deployed systems. Although cross subsidies have made off-grid PV systems affordable for users, systems often fell short of energy demand. Notably, we found that Peruvian officials appear to be unaware of the importance of local participation, and there is a significant mistrust between the government and the rural population (especially in areas where mining is extensive. As a consequence, most of the projects are still designed without the participation and engagement of the communities, which has frequently led to project failures, payment defaults, and inhibited seizing opportunities regarding productive uses of off-grid PV systems. We expect that our findings may help Peruvian institutions to address the most

    In the last few decades, there has been a constant migration of rural population to urban areas looking for employment and better quality of life. During the same period, industrial sector grew significantly and became economically more important than the rural sector. Consequently, the industrial sector became government's first development priority. In addition, the energy system was focused on large power plants energy production and high potentials long distance transmissions to large energy consumers, urban centers and industries. Limited efforts were done to provide energy to small and dispersed rural consumers as it seemed to be economically less attractive. This article, therefore, shows the importance of rural electrification over human, economical and social development including its impact across the rural communities' boundaries. While regarded as an important factor for development, rural electrification is, however, a function of many input factors in a mutual dependence relationships, reinforcement and feedback loops. Besides of the evident benefits of increased comfort and satisfaction levels to the rural population, other benefits of rural electrification includes improved access to information and communication media, agricultural mechanization and consequent improvement of the agricultural productivity. Agricultural sector is an important part of the industrial production chain: each R$ 1,00 invested in rural electrification generates R$ 3,00 along the production chain and increases the consumption of durable goods, Word Bank, Gazeta Mercantil (1999). For the population and urbanization control, rural electrification creates favorable conditions to maintain people in the rural areas as such reducing government expenditures for urban infrastructure which is more expensive than the rural one. Moreover, this reduces incidences of unemployment in big cities as it generates jobs in the rural sector. Implementation of a combined rural

    Depending on a daily load demand, distance from the utility grid and the available solar energy, the rural villages electrification with a hybrid photovoltaic (PV) system can be a cheaper solution than the classic electrification, by connecting them to the utility grid. Besides PV generator, the considered hybrid system is consisted of a battery and a diesel genset. For the concrete case - rural village with estimated daily load demand of 15.5 kWh/day, with the computer program PVFORM, which is modified for such hybrid system, were simulated a few hundreds PV systems, with different sizes of the PV generator and of the battery capacity. Analyzing the obtained results, it can be foreseen the influence of the component size on the system functionality. From the mass of possible system combinations, it is chosen one that has 42 % lower initial investment, than the initial investment for connection of the village to the utility grid. (Original)

    The Brazilian government has the ambition to provide complete electricity coverage for all citizens as a means to promote development and reduce inequalities. Full coverage implies the provision of electricity to 15 million people in the country by the end of 2010 through the program Luz para Todos (LPT - light for all) launched in 2003. So far, 11 million people have benefited, 2 million of which live in the Amazon. In this paper, we analyze the linkages between development and rural electrification through the Human Development Index (HDI) and within the context of the Amazon. We examine the suitability of the HDI as a planning and monitoring tool for improving energy access and development. We show that the recognition of electricity access as a driver for development has led to concrete goals for electrification, actual action and welfare improvement. Our study serves to highlight the role of LPT in the development of the Amazon region, and the specific features and achievements of the Brazilian policy for universal electrification. We conclude that some challenges related to the electrification of isolated areas still lie ahead. We finalize with a discussion on the relevance of the Brazilian experience to other developing countries.

    The socio-economic implications regarding the establishment of a recurrent fund for the rural electrification of developing countries are discussed in conjunction with an evaluation of the current status of rural electrification. The technological developments in off-grid power production has made rural electrification feasible but several important issues need to be addressed. This paper emphasizes the need for consideration of the scale of the problem. Results of the assessment show that the involvement of the private sector in rural electrification is still minimal. Moreover, in many countries off-grid power production is either impossible or illegal

    This paper aims at quantifying the impact of rural investment in power sector on the rural economic development and poverty reduction in China. An econometric model was developed and six Chinese provinces with different economic background are studied. These provinces comprise Jiangsu and Liaoning with well-developed rural economy, Hebei and Henan with medium-developed rural economy, and Shannxi and Xinjiang with the least-developed rural economy. Over 20-yr historical data for the six provincial rural areas--counties and below, was collected in rural economic development, households, population, per capita income, community infrastructure development, capital investment, electricity consumption, output values in agriculture sector, and township and village enterprises. SPSS V10.0 software program was used in the research. This paper concludes that priority of capital investment in rural power sector should be given to Jiangsu and Liaoning if the objective of the investment is to develop rural economy, and that the priority should be given to Hebei and Henan if the objective is to reduce poverty in rural area

    Rapid growth in economic development, coupled with the absence of an electric grid in large areas of the rural countryside, have created a need for new energy sources both in urban centers and rural areas in China. There is a very large need for new sources of energy for rural electrification in China as represented by 120 million people in remote regions who do not have access to an electric grid and by over 300 coastal islands in China that are unelectrified. In heavily populated regions in China where there is an electric grid, there are still severe shortages of electric power and limited access to the grid by village populations. In order to meet energy demands in rural China, renewable energy in the form of solar, wind, and biomass resources are being utilized as a cost effective alternative to grid extension and use of diesel and gasoline generators. An Energy Efficiency and Renewable Energy Protocol Agreement was signed by the U.S. Department of Energy with the Chinese State Science and Technology Commission in Beijing in February, 1995. Under this agreement, projects using photovoltaics for rural electrification are being conducted in Gansu Province in western China and Inner Mongolia in northern China, providing the basis for much wider deployment and use of photovoltaics for meeting the growing rural energy demands of China. copyright 1997 American Institute of Physics

    Rigorous impact evaluation that includes appropriately selected control groups must be a part of rural electrification program designs. Budgeting evaluation activities and engaging with evaluators at an early stage improves to likelihood of having a high quality evaluation design; plus, if deviations occur after the design stage, the evaluators are better prepared to adjust the design so that the impact results remain informative to policy makers and future program designers. Another take-away is to use unified framework to specify the expected outcomes and the plausible sizes of impacts. If done at the beginning of the program, this will provide context to the kind of discussion that policy makers should engage in (e.g. if they should focus on health benefits or the potential to diffuse information campaigns to rural households). These points focus mostly on internal validity, but we also need to focus on external validity as well. Large scale rural electrification programs will provide an opportunity to test if the results from small scale impact evaluations translate to other settings. Something we have not stressed so far but that is important to keep in mind are the complementarities in the provision of different type of infrastructure. Large projects can provide an opportunity to explore complementarities with other infrastructure programs, such as mobile telephony, road access, and improved water and sanitation access. They can shed light on what are the most welfare-enhancing policy options when deciding what types of infrastructure to provide in rural areas, and especially to poor rural households. Finally, we reiterate the need to use an objective function that casts a wider net when deciding where to place electrification programs. Focusing solely on cost minimization can result in missed opportunities. When deciding where to deploy the electric grid in rural areas it is imperative to take into account the potential profits, specifically the agricultural

    The author discusses the history of rural electric cooperatives (REC) in the United States, and the broader question of whether such organizations can serve as a model for rural electrification in other countries. The author points out the features of such cooperatives which have given them stability and strength, and emphasizes that for success of such programs, many of these same features must be present. He definitely feels the cooperative models are not outdated, but they need strong local support, and a governmental structure which is supportive, and in particular not negative.

    Rural areas, the world over, are characterised by low levels of connectivity to electrical energy, despite the fact that electricity has been universally acknowledged as one of the most important propellant for community and national development. Botswana is not immune to this trend. Consequently, available evidence puts the overall level of electrical connectivity in Botswana rural areas to just 12%. A plethora of factors are responsible for inhibiting high levels of access to electrical energy by rural communities. Some major impediments often cited as causing ineffective energy provision to rural-based communities include, among others, the following: (a)geographical set-ups of the concerned communities; (b)inappropriately conceived energy policies; (c)low-income status of most rural inhabitants. This paper, therefore, examines Botswana's policy on energy supply with the view to confirm or deny any correlation between the above factors and the low-levels of electrical connectivity in the country's rural communities, as well as many others that may have impacted on this state of affairs. The policy is evaluated by undertaking a comparative study of its implementation on two seemingly geographical contrasting rural communities within the country

    The investment requirements to achieve the United Nations' universal electricity access goal by 2030 are estimated at 640 billion US Dollars. The assumption underlying this goal is that electrification contributes to poverty alleviation in many regards. In recent years, a body of literature has emerged that widely confirms this positive poverty impact assumption. Most of these studies, however, are based on data from Asia and Latin America. This paper challenges the transferability of impact findings in the literature to the African context. Using a unique data set that we collected in various African countries we suggest that impact expectations on income, education, and health should be discounted considerably for Africa. In many cases, the low levels of electricity consumption can also be served by low-cost solar alternatives. To ensure cost-effective usage of public investments into rural electrification, we call for careful cost-benefit comparisons of on-grid and off-grid solutions. (authors)

    The workshop was attended by 28 participants from Kenya, Mozambique South Africa, Sweden, Tanzania, Uganda, Zambia and Zimbabwe, representing energy service providers (private, public and cooperative), consumer groups, public energy authorities, researchers, consultants, NGOs and the Swedish International Development Cooperation Agency. The topic of the workshop was how different types of electricity delivery mechanisms - i.e. the combination of an energy supply technology and the organisation managing it - can support rural development. Which energy services have high priority for rural development? What are the appropriate delivery mechanisms? How can the expansion of different delivery mechanisms be supported and made to work efficiently? These are some of the key questions that were discussed in the workshop. The objectives of the workshop were to share experiences and develop a better understanding of existing and potential energy delivery mechanisms that contribute to development in rural areas in Eastern and Southern Africa. The workshop was targeted at, amongst others, the authorities which are in the process of being formed, or have recently been formed, to take charge of rural electrification such as the Rural Electrification Agencies and Rural Electrification Funds. Four case studies were presented and discussed to provide an introduction to the topic, and concrete examples of different delivery mechanisms were given to inspire the workshop discussions. Focus group discussions were used to explore the participants perceptions and experience of: (i) what rural development is, (ii) what role energy plays in rural development, (iii) which energy services are important for rural development, (iv) which delivery mechanisms are used and appropriate for different situations of energy service delivery in rural areas, and (v) what the institutional framework requirements are for delivering different types of energy services and supporting different types of

    Zambia is well endowed with hydropower and other energy resources, which could facilitate production of electricity for both urban and rural areas of the country. The country has an installed electricity generation capacity of 1786 MW and undeveloped hydropower potential of over 6000 MW. In the last few years, demand has been growing and it is anticipated to outstrip supply in 2008. The load growth is attributed to increased mining activities and development of the industrial base. The country is also endowed with abundant natural resources such as arable land, water, minerals and wildlife. With the available resource base, electricity along with other social and economic infrastructure such as roads and telecommunications could facilitate increased economic activities. In rural areas, electricity could be used for crop irrigation, agro-processing, small-scale mining and to facilitate tourism. However, rural electrification (RE) faces many challenges such as long distances from existing power stations to targeted rural areas, low population densities, high poverty levels and low skills availability. These and other factors have contributed to continued low levels of access to electricity in rural areas of the country. Measures so far undertaken to facilitate access to electricity in rural areas of Zambia include the adoption of a new National Energy Policy (NEP) in 1994. With regard to the electricity sector and RE in particular, the NEP was aimed at facilitating increased access by liberalising and restructuring the electricity market and promoting the use of low-cost technologies and decentralised renewable energies. To facilitate implementation of the new policy, the government established a legal and institutional framework by enacting new legislation, namely, the Electricity Act and the Energy Regulation Act in 1995. The Electricity Act provided for liberalisation and regulation of the electricity sector, while the Energy Regulation Act provided for the

    Energy demand is rapidly growing throughout much of the developing world, where an estimated two billion people, mostly from sparsely populated areas, currently live without electricity. As electrical energy systems are selected to help meet these people's electricity need, the environmental ramifications of the generating systems become increasingly important. Photovoltaic systems generate electricity without emitting greenhouse gases, and result in global, regional and local air quality advantages. In this work we intend to carry out research and development of photovoltaic solar cells for rural electrification - especially solar powered water pumping. (author). 56 refs, 11 figs

    Despite a large number of rural electrification projects being implemented in developing countries, there are few published in-depth evaluations of the effects of these projects on sustainable development. There is also no generally accepted method for the assessment of such effects that includes all relevant aspects of sustainability. An issue of growing importance is whether rural electrification implemented by private entrepreneurs or other non-governmental organisations contribute more effectively to sustainable development than the conventional approach where rural electrification is the responsibility of a government utility. This paper presents a method for sustainability evaluation based on the use of 39 indicators. The proposed indicators cover the five dimensions of sustainability: technical, economical, social/ethical, environmental and institutional sustainability. The paper presents the indicators and gives a detailed example of the procedure to calculate an indicator based on information that can realistically be collected in field studies. It is suggested that this interdisciplinary approach will lead to an improved basis for evaluation of projects than previous, more limited approaches. Projects promoted on the basis of information only about prioritised dimensions of sustainability, such as environment, may fail as a result of weaknesses in other dimensions. The proposed method may reduce this risk

    More than 2000 million people, mostly in developing countries, live in rural areas without access to grid connected power. Conventional approaches to supplying power, whether through extension of existing grids or through stand-alone 'mini-grids' based on diesel generator sets, or even on renewable energy minigrids, require large investments which are unlikely to receive priority in competition with more economically and politically attractive investments in urban areas. Domestic PV lighting and broadcast reception kits (DLKs), comprising, typically, a 30-60 W panel, an automotive battery, a charge indicator, and dc fluorescent lamps can be furnished and installed for about $500. DLKs are now used in the Dominican Republic, Kenya, Sri Lanka and many other countries. DLKs provide a minimum essential service with low overheads. Given the necessary credit facilities, they can give better service at comparable costs in comparison with kerosene lamps and dry cell powered radios. They also permit a substantial degree of local manufacture, thus saving on foreign exchange. This movement is starting in many countries on a purely commercial basis. The process could be greatly accelerated if 'seed money' in the form of revolving funds could be made available. (author). 1 fig., 11 tabs

    This paper presents, from a financing aspect the broad issues involved in a plan to provide solar home systems (SHS) to provide rural electrification in several areas of rural Indonesia. The paper discusses the approaches being used to provide funding, develop awareness of the technology, and assure the success of the project. The plan involves the use of grant money to help with some of the initial costs of such systems, and thereby to encourage local financing on a terms rather than cash basis. There are needs for market development, and development of a business structure in the country to support this type of technology. Provided this plan can succeed, it may serve as a model for further efforts.

    In an ideal world, rural electrification would serve the goal of socio-economic development. Improved electricity access can power rural industries, enhance agricultural productivity, and provide households with more productive time for study and work at night. Brazil's national rural electrification program has promised to target poor and remote rural communities, but has this goal been met? We analyze statistically representative data from Brazil's Census of 2000 and 2010. While Brazil has reached municipalities with low initial electricity access rates, rural electrification has not targeted the least developed municipalities. Furthermore, we find that the government has not reached the most remote and sparsely populated rural communities. Primary policy implications include more precise targeting of the least developed municipalities, complementary interventions to promote rural development, and increasing investments into distributed energy, such as off-grid solar power. With these strategies, Brazil and other countries facing similar issues can enhance the socio-economic benefit of rural electrification. - Highlights: • Progress of rural electrification in Brazil, 2000–2010. • Low initial electrification rates predict high achievement. • Lack of socio-economic development predicts neither high nor low achievement. • Remoteness predicts low achievement.

This programme has been focused in three aspects: the domestic electrification, users participation and transfer technology. At present, there are about 1,500 electrified dwellings distributed in the Bolivian high plateau. We have got deep knowledge about life style and organization of the aymara Indians who are the inhabitants of the working zone. We think that this knowledge can be very useful for a large scale introduction of PV solar energy in this region. Finally, we present a new way to transfer PV technology to developing countries. Thanks to this programme a group of aymara Indians is able to manufacture charge regulators and electronic ballast to use in the PV installations of the programme.

    Development and proliferation of renewable energies are sponsored since 1983 by the European Union, normally up to 40% of the cost. (Programme THERMIE and predecessors). In the frame of this programme for more than one hundred projects of all kinds with thousands of photovoltaic energy supply systems have been implemented in Europe, 29 of these projects with 939 single pv-systems concern electrification of rural sites (e.g. agriculture) or isolated sites (e.g. mountain huts). Most of the single systems are of small size, 50 to 1000 Wp. A few of the systems are larger, up to 25 kWp, and supply local isolated mini-grids. In this paper the main features of the systems in six european countries are presented: The technical, economical and social results as well as the contributions of the Electric Power Utility (EPU`s) to these electrification are discussed.

    Development and proliferation of renewable energies are sponsored since 1983 by the European Union, normally up to 40% of the cost. (Programme THERMIE and predecessors). In the frame of this programme for more than one hundred projects of all kinds with thousands of photovoltaic energy supply systems have been implemented in Europe, 29 of these projects with 939 single pv-systems concern electrification of rural sites (e.g. agriculture) or isolated sites (e.g. mountain huts). Most of the single systems are of small size, 50 to 1000 Wp. A few of the systems are larger, up to 25 kWp, and supply local isolated mini-grids. In this paper the main features of the systems in six european countries are presented: The technical, economical and social results as well as the contributions of the Electric Power Utility (EPU`s) to these electrification are discussed.

    To date, the use of wind power for rural electrification has been limited. However the fact that micro-wind turbines can be manufactured using only basic workshop tools, techniques and materials, and therefore can be produced locally is often overlooked. Local manufacture has the potential to boost the local economy, build local capacity, reduce costs and produce resilient and flexible energy systems. However, locally manufactured technology must be seen as socially embedded due to the variety of local knowledge, skills, equipment and materials needed to construct and maintain such systems, as well as the organisational structures needed to ensure their long term sustainability. Evidence from successful initiatives suggests that stable institutional support from intermediaries such as the local/national government or NGOs is necessary to foster the development of a wind power industry based on local manufacture. The roles of these intermediaries include identifying and targeting windy areas with favourable environmental conditions, conducting research and development, collecting feedback from end users, creating supply chains for new parts and materials and developing relevant knowledge and skills. In this paper, three case studies of specific initiatives are analysed to draw out the social, economic and technical factors that could facilitate wider adoption of the technology. - Highlights: ► Local manufacture of wind turbines often overlooked for rural electrification. ► Flexible to adapt to local context and benefits local economy, capacity and supply chain. ► Development of technology discussed and 3 case studies of dissemination analysed. ► Critical factors: institutional support, system level planning, continuity of supply. ► Dissemination successful in Inner Mongolia; work continues elsewhere.

    It is the government of Malaysia's vision to see that the rural community is not left behind in its endeavour to be an industrialised nation in the year 2020. The standard of living in the rural areas is very far different from that in the urban areas. To obtain equality the standard of living of the rural folks need to be ungraded. This is done largely by electrification. Electricity has been in the past the catalyst for development and raising the standard of living of the poor. Electricity supplied by the nation's electricity company might not reach all remote areas and therefore there must be a means to provide alternative electrical supply to these places. Present method employ the use of diesel generator sets to provide electricity. The availability of biomass source of supply in the rural areas could be effectively exploited to provide alternative source of energy via a gasification system to run a reciprocating engine coupled to a generator to generated electricity. A small-scale biomass gasification generator set in the range of 2-5 kW is suitable to provide electrical supply to a typical house in the rural area. The present use of biomass source of energy is in its utilisation to provide source of heat for cooking. Several tests have been conducted and the performance is very good. Alternatively another medium scale system generating about 50-20O kW would be suitable for a typical village having about 50 houses. A small-scale system has been developed in USM to provide 5 kW of electrical power. The system used a petrol engine and produces an overall efficiency of 7% with a specific consumption of about 3 kg/kWh. The biomass material used is wood. However for application in the rural areas the biomass material will depend on the type available. A further 50 kW system is being develop in USM. (Author)

    Full Text Available The electricity access in Sub-Saharan African countries is below 10%; thus, introducing a microgrid for rural electrification can overcome the endemic lack of modern electricity access that hampers the provision of basic services such as education, healthcare, safety, economic and social growth for rural communities. This work studies different possible comparison methods considering variations such as land area required, location for the storage, efficiency, availability and reliability of energy resources, and technology cost variability (investment cost and levelized cost of electricity, which are among the major key parameters used to assess the best possible utilization of renewables and storage system, either using them in the form of integrated, hybrid or independent systems. The study is carried out largely with the help of the Micropower optimization modeling simulator called HOMER for Ethiopia. As a result, the study proposes the use of Photovoltaic (PV–Wind–Hydro–Battery hybrid system model that concludes the optimal configuration of power systems at affordable price for underserved rural communities.

    This paper analyses the field performance of different off-grid generation technologies applied to the electrification of rural villages. Autonomous diesel generators are the most extended technology. It is a well known application, although it has also some disadvantages: fuel transportation and consumption costs, maintenance needs or environmental problems. In places where accessibility is difficult and costly, the use of local energy resources (basically renewable) constitutes a significant advantage. Due to the intermittent character of those resources, renewable generation systems are sometimes associated to diesel gen-sets in order to increase the reliability of supply of small and medium-size communities. A comparative analysis between diesel, hydro-diesel and photovoltaic-diesel technologies is presented in this article. It is based on data collected from systems installed in the rural area of the province of Jujuy, northwest of Argentina. The study covers from year 2001 to 2008, with a research universe of 16 locations supplied by thermal diesel generation (1 with a large-diesel system and other 15 with smaller ones), 5 locations with hydro-diesel and 7 with photovoltaic-diesel systems. The energy demand evolution of rural villages is also studied because of its influence on the system operation and sustainability. (author)

    2012-01-01

    Rural electrification is considered to be a key strategy for poverty alleviation and sustainable development. It should therefore include (1) expanding electricity access and (2) enable new consumers to increase their electricity consumption. In this paper we ask how Brazil’s recent rural electrification efforts have managed to reach these objectives. A new method to measure energy and income equity is presented which uses estimations of non-parametric density curves for the analysis of energy and income distributional trends following electrification. By applying our method to a panel data set from two Brazilian states situated in the country’s poor northeast region we find that (1) rural consumers take up electricity consumption after electrification, and that (2) low consumption levels give way to higher electricity consumption levels after only a few years. This indicates immediate social benefits for households through consumption of electricity services. However, our analysis cannot verify a direct link between electricity use and rural income generation in the short term. The results emphasize the need for government and other actors to integrate rural electrification into broader rural development strategies in order to enable long-term welfare increases through electricity use. - Highlights: ► Comprehensive analysis of Brazil’s recent rural electrification efforts. ► New methodology to analyze energy and income equity trends ex post electrification. ► Analysis indicates immediate social benefits for electrified households. ► We cannot establish a direct link between electricity use and income in the short-run. ► Electrification thus should be integrated in long-term rural development strategies.

    The GTZ (Federal Republic of Germany Technical Cooperation Society) has developed a general project design system, particularly for Renewable Energy, that systematically covers all aspects necessary in their planning and implementation, so that their effects are sustainable in the long run, and cover as well all the requirements of a determined diffusion. This is what they have called System Management. This methodology of project implementation can be described as capable of being applied to any action area, and has already proved and validated its efficiency in projects where it has been applied. The main reason for its use is based on the correction of previous experiences with projects that had a tendency towards one area of action alone, in a much too exclusive way -mainly the technological- neglecting important aspects in the sustainability of technologies being introduced. The experience of PROPER - Bolivia (Programa para la difusion de energias renovables), who has been applying this system to its projects, is being used as a methodological basis.

  19. SELCO: A model for solar rural electrification in India

    Hande, H. Harish

    1999-11-01

    The following thesis presents the concept of a Rural Energy Service Company in India, known as SELCO. The model is being set up as a sustainable proposition for the implementation of solar photovoltaics as a viable alternative to provide reliable home lighting in the rural areas of India. The SELCO approach has already achieved noteworthy social and commercial results. Institutional, policy and operational problems have long plagued the rural electrification programs in India, resulting in thousands of villages without access to electricity. SELCO is a solar energy service company operating in Southern India since 1995, focusing on the enormous untapped market for home lighting where thousands of households have no access to electricity and severe power shortages face those already connected to the electric grid. The Company has installed nearly 2,000 solar home lighting systems. From a modest two employees company in 1995, it has grown to 35 in 1997 and from one office to eight. The hypothesis to be tested in this study is that in rural India, in a market not subsidized by the government, a solar service company with available loans from local banks and cooperatives and with sales, installation, and maintenance personnel in the villages can be successful in introducing photovoltaic systems to provide basic amenities such as lighting and water pumping for the improvement of the quality of life, public health, and the environment. The initial success of SELCO lends considerable evidence to the acceptance of the hypothesis. To accomplish its mission, SELCO works with commercial, retail, and rural development banks with large rural branch networks to stimulate loans to SELCO's customers based on a standard set of attractive financing terms. SELCO through its successful model has convinced the policy makers that a way to increase rural families' access to consumer financing for solar home lighting systems is through the existing financial network available in the

    -stepped or rewrote local laws when necessary to aid development. Finally, Johnson heavily influenced decisions pertaining to personnel during his expansion of territory and consolidation of control. Ambition and opportunism created numerous occasions for patronage, publicity, and unbridled expansion. Within the LCRA, Johnson shifted focus from dam construction to development of rural electric cooperatives. Johnson's promotional efforts made the congressman the target of various groups seeking support for river development within their respective communities. At times, Johnson used heavy-handed tactics to achieve desired results. Finally, Johnson and his operators continued to marginalize members of the Karnes cooperative until personally ordered to stop by the National Director of the Rural Electrification Administration. Johnson's involvement in determining the location of a cooperative headquarters in Karnes County to cultivate the support of local political players demonstrates how ambition, expansion of name-recognition, and the cultivation of political power at the local level to build a state-wide machine define Johnson's early involvement in rural electrification and multipurpose river development in late 1930s Central Texas. Therefore, this thesis builds upon traditional interpretations of Johnson's participation in rural electrification and properly places his involvement into a more complete context. This thesis also breaks up the neat compartmentalization that previously occurred to create a more comprehensive outlook. (Abstract shortened by UMI.).

    Rural electrification is an integral component of poverty alleviation and rural growth of a nation. A developing nation, like India has 72.2 percent people living in rural areas. Still, electricity has not played an effective role in the socio-economic growth of villages. The Government of India has an ambitious target of providing electricity to all villages by 2008 and all rural households by 2012. Steps are already initiated with Rural Electric Corporation, Rural Electricity Supply Technology Mission, State Electricity Boards led reforms, Reforms in Power Sector, Electricity Act 2003, Rajiv Gandhi Grameen Vidyutikaran Yojana etc. An attempt has been made in this paper to assess the present status of rural electrification in India and the major factors contributing to rural electrical distribution. Steps initiated by the Government of India through Rural Electric Corporation (REC) and a successful case study of the people's participation model is presented. (orig.)

    2005-01-01

    The electrical sector has traditionally been organized as a natural monopoly. The intensity in capital of the grid and the public service obligation of electrical distribution led to the creation of electrical companies with exclusive territorial concessions. This approach has recently been challenged because of its failure to electrify remote rural villages in developing countries. A new set of solutions appeared under the umbrella of Decentralized Rural Electrification (DRE) thanks to technological innovations that replace collective infrastructures with individual systems. However, the widespread deployment of decentralized technologies remains impaired by numerous obstacles at various levels: institutional, legal, organizational, social, financial... New models that take into account the specificities of DRE must now be imagined. The study of two case studies in Morocco and India provide insightful examples of possible strategies to accelerate the deployment of DRE and therefore attain the objectives of rural electrification. Two major policies stand out: public service delegation and the approach of delivering equipment by the public market. Even though these models are too recent to conclude on their viability and permanence, they provide guidelines for the public and private players of the sector to generalize the access to electrical services to rural populations in developing countries, and contribute to their development.

    The author reviews trends in rural electrification over the past 30 years in Sub-Saharan Africa. In particular, it is shown that motivations for rural electrification programs have evolved significantly over the years, following changes in development paradigms. The author finds, however, that knowledge of the impact of this has only marginally improved: low connection rates and weak productive utilization identified in the 1980's remain true today, and impacts on such dimensions as health, education, or income, though often used to justify projects, are largely undocumented. Indeed impact evaluations are methodologically challenging in the field of infrastructures and have been limited thus far. Nevertheless examples of recent or ongoing impact evaluations of rural electrification programs offer promising avenues for identifying both the effect of electricity per se and the relative effectiveness of approaches to promoting it

    2015-01-01

    This study proposed a power generation system suitable for rural area application. The electrification options were proposed for secondary schools, health centres, households and trading centre loads using solar PV system, diesel fired generators, biogas co-fired diesel generators and grid extension. The study is based on simulation, modeling and optimization of renewable energy system. Designs for the options considered were based on the electricity demand and environmental conditions of Arua district. From the designs, capital costs for each option were determined. This was used in carrying out simulations in HOMER computer program to come up with the most cost effective options. Sensitivity analysis was carried out to determine the effects of variation in costs such as diesel price and capital cost of solar PV system.Based on simulation results, it has been found that the trading centre, with 500 kW of electrical demand, must be electrified using the grid extension. The breakeven grid distance is 75.1 km. Grid extension become cost effective compared to diesel generators and solar PV system within this distance. The load at household level ranges from as low as 16 W to 5 kW. For 103 W peak load, the most cost effective option was solar PV system. The second best option was biogas co-fired diesel generator. For schools and health centres with load of up to 15 kW, biogas co-fired generator is the best compared to the total cost of 18 kW diesel fired generator which is higher. Therefore, where biogas cannot be generated, diesel generators should be used. Based on the amount of pollutants produced, a biogas co-fired diesel generator is the best option. (full text)

  9. Renewable energy for rural electrification in developing countries

    Science.gov (United States)

    Morgenstern, Joy

    The environmental destruction caused by traditional methods of generating electricity and the environmental benefits of using renewable energy technologies are well-known. In additional to the environmental benefits, small, decentralized renewable energy systems are often the most economical way to electrify the rural areas of developing countries, where most of the world's unelectrified population lives. However, diffusion of these systems is proceeding very slowly and many of these projects have failed. This dissertation examines the hypothesis that an important determinant of the success of these projects is the extent to which they are compatible with the social and cultural attributes of the communities in which they are located. The hypothesis was examined by evaluating sixteen solar, wind and hybrid electrification projects in Mexico, using a procedure which rates projects according to criteria which reflect technical, economic and financial, environmental, and sociocultural factors deemed necessary to achieve success. Reasons for poor ratings within these criteria were then used to determine six preconditions for project success. The evaluation indicates that most of the wind and hybrid projects visited had low success ratings because of technical problems. The solar home system projects experienced few technical problems, yet many were unsuccessful. Most of the projects were unsustainable due to lack of financial resources, insufficient financial mechanisms, poor user training. In none of the communities were the projects economically viable, nor were they compatible with the needs of the users. The future success of even the most successful projects seen is doubtful because of the lack of provision for any maintenance by trained technicians and the scarcity of financial resources. A direct relationship between failure at the sociocultural criteria and overall project failure was not found. In most cases, failure at particular criteria could be attributed

    Rural electrification is essential for bringing about social and economic developments, but the progress is distressingly slow in most developing countries. The Bangladesh Rural Electrification Program (BREP) has been highlighted as a positive case among developing countries, but from 2006 onwards there have been doubts about the program's chances of success. In this paper, we examine the rural electrification practices in Bangladesh and evaluate the claim that, whereas they were successful up to 2005, they then began to decline in terms of their performance. This study determines the factors behind the initial success of the program as well as those that account for the recent downturn in BREP. We found that the BREP was a clear success in terms of its growth and progress; however, its performance has been declining since 2006. The key driving factors for the success of this program had to do with prioritizing system investment, community involvement, anti-corruption features, standardized practices and performance-based incentives while excluding political parties. The major issues accounting for the decline were the lack of organizational autonomy, a shortage of funding, unrealistic tariffs, and power supply shortages. Renewable-based, off-grid technologies have been successfully supplementing the on-grid program in remote areas. - Highlights: • Rural electrification is essential for bringing about socio-economic developments. • The pace of rural electrification in the developing countries has been very slow. • A multitude of issues plays behind in making the task a success or a failure. • Lack of policy reforms, unrealistic tariffs are the main hinderers. • Rural electrification cannot be successful by sticking to a rigid model

In order to fill out this gap, the Brazilian government established as a goal reaches the universalization of the public electric energy services to provide conditions for the improvement of the quality of life of the urban and rural population. In this sense, the evaluation of the recent experiences in rural electrification can be of great help to achieve this objective in an efficient way. The results of such evaluation can point out some actions for the universalization of the attendance seeking for the continuous improvement of the planning and decision making process, either in the direction of the attendance of the proposed goals or in the poverty mitigation.

    The economic and infrastructural disparities between the rural and urban communities of most developing countries in general and in terms of energy access in particular are quite glaring. China presents a good example of a developing country that has successfully embarked on rural electrification projects over the last few decades and achieved a great feat of almost 100% electrification rate (. World Energy Outlook, 2009, International Energy Agency, Paris (see IEA website at (http://www.worldenergyoutlook.org/electricity.asp).)). The purpose of this paper is to find out how China has achieved this feat; how China’s rural energy projects were financed and whether China provides lessons for other countries to follow. The above questions are examined through an extensive literature review and the paper finds that unlike many other countries following the top-down approach to rural electrification, China has preferred to use a phased development through a bottom-up approach where local resources, and village level development and empowerment played an important role. While the state provided the overall guidance and financial support, the integrated rural development approach has produced local-level solutions that are subsequently integrated to produce an alternative development pathway. Strong government commitment, active local participation, technological flexibility and diversity, strong emphasis on rural development through agricultural and industrial activities and an emphasis on capacity building and training have also played an important role in the success. However, despite achieving the universal access objective, China still faces a number of issues related to rural electricity use, especially in terms of regional use patterns, long-term sustainability of supply and commercial operation of the systems. The Chinese model could serve as an inspiration for other developing countries trying to ensure universal electricity access. - Highlights: ► It

  13. Assessing the Impacts of Rural Electrification in Sub-Saharan Africa: The Case of Ethiopia

    Science.gov (United States)

    Aragaw, Mekonnen Lulie

    This study links rural electrification and the transition to modern energy services with poverty reduction and rural development in Ethiopia. Benefits of rural electrification in reducing poverty and accelerating rural development in low-income developing countries have been insufficiently researched. This study analyses available empirical evidence at a local level and examines how electricity access translates into productive use beyond powering radios and lighting. A survey of 336 households was conducted in Northern Ethiopia on impacts of electrification on four rural towns with varying number of years of access to electricity. Evidence at household and community levels shows that access to electricity was followed by an increase in household connectivity rate, and slow transition to modern energy services based on level of household income and number of years of a household's connection to electricity services. The pace of transition to modern energy services was slow, and household energy poverty and dependence on biomass fuels continued in most rural towns, having little impact on improved environmental management practices. Improvement in rural livelihood, poverty reduction, and delivery of public services was highest for those with more years of access to electricity, and higher income households. The fact that impacts of RE depend on number of years of a household's electricity connection implies gradual improvements rather than immediate benefits after connection. In the short-term, households improved their quality of life through better lighting and reduced indoor-air pollution. In the medium and longer-term, households and communities diversified their income and received improved public services such as education, health, and potable water. Further benefits were wider off-farm and non-farm employment, increased rural markets, and improved environment for rural development. Very poor households benefited least, while those better-off utilized

    Rural electrification (RE) has gained prominence over the past two decades as an effective means for improving living conditions. This growth has largely been driven by socio-economic and political imperatives to improve rural livelihood and by technological innovation. Based on a content analysis of 232 scholarly articles, the literature is categorized into four focal lenses: technology, institutional, viability and user-centric. We find that the first two dominate the RE debate. The viability lens has been used less frequently, whilst the user-centric lens began to engage scholars as late as 2007. We provide an overview of the technological, institutional and viability lenses, and elaborate upon the user-centric lens in greater detail. For energy policy and practice, we combine the four lenses to develop a business model framework that policy makers, practitioners and investors could use to assess RE projects or to design future rural electrification strategies. - Highlights: ► Review of two decades of rural electrification research. ► Content analysis of 232 scholarly articles. ► Literature is categorized into four focal lenses: technology, institutional, viability and user-centric. ► We develop a business model framework for rural electrification strategies.

    The effective rural electrification method varies with economic status and geographical location, and the benefits of decentralized generation differ for each energy system depending on its characteristics. This paper evaluates the most effective generation strategies with rural electrification in an optimized power system of Papua New Guinea (PNG) using a linear programming model. The energy system model developed for the study includes decentralized generation, centralized generation, and grid systems of electricity and gas with consideration for the current energy system and infrastructure. Two methods of rural electrification, decentralized generation and grid extension, are compared with and without the Clean Development Mechanism (CDM). The results of simulations show that extending the power grid that allows economical generation such as coal-fired power and hydropower to supply rural electricity is a more cost effective way for rural electrification. Although grid extension is more capital intensive than decentralized generation, the former reduces the total system cost through reduction of the fossil fuel use. Extending the power grid is also effective at attracting CDM investments, since it makes the power system flexible and provides opportunities to advance low emitting energy such as hydropower.

    The provision of energy in rural households and communities has several implications and uses. The field experience drawn in this paper shows the efforts and approaches employed to make the optimum use of the electric energy through enterprise creation. If rural electrification is left to grow without any directional inputs, experience has shown that, beyond obvious use for lighting, radios and basic home-appliances, uses which might bring economic development to an area, are slow to emerge. To be of development benefit to an area, electricity should be employed in enterprises which employ local people, and add value to local resources. However, contrary to the conventional ideology, the empirical observation from this field experience in one of the hill districts of Nepal demonstrates the positive effect of a rural-electrification programme with various innovative approaches, practical tariff policies and varieties of motivational and entrepreneurship development mechanisms. These strategic approaches with supportive institutional mechanisms have proven conducive for fostering the growth of local enterprises, thus creating employment and resource harnessing. Complementary service mechanisms and policy coordination is a necessary precondition for an effective use of power in the rural community rather than the rhetoric policy of rural electrification in isolation. Electrification in isolation, without any promotional or supportive mechanisms, still creates pitfalls. (author)

    The International Energy Agency estimates that more than a billion people remain without household electricity access. However, countries such as India have recently made major progress in rural electrification. Who has benefited from these achievements? We focus on 714 villages in six energy-poor states of northern and eastern India to investigate trends in electricity access. We use data both from the 2011 Census of India and an original energy access survey conducted in 2014 and 2015. During the three years that separated the surveys, distance to the nearest town and land area lose their power as predictors of the percentage of households in the village that has access to electricity. In this regard, the Indian government's flagship rural electrification program seems to have managed to overcome a major obstacle to grid extension. On the other hand, socio-economic inequalities between villages related to caste status and household expenditure remain strong predictors. These findings highlight the importance of socio-economic barriers to rural electricity access and alleviate concerns about remoteness and population density as obstacles to grid extension. - Highlights: • Empirical analysis of rural electrification progress in India. • Geographic differences across villages no longer explain electricity access. • Social and economic inequities remain stark. • Future policy should focus on household electrification within villages.

    Electricity is universally recognized as a necessary, although not sufficient, requirement for social and economic development. However, increasing access to electricity in developing countries has proven to be difficult and expensive, particularly in rural areas. In this article, we analyze the dynamics of the relationship between electricity and socio-economic development by means of a cost-benefit analysis of a typical rural electrification project in Mozambique, assessing the impact of electricity on households, education, agro-business, commerce, and the public sector. We show that rural electrification can be commercially viable and cause structural transformation in rural areas within a short period of time. Finally, illustrated by the actual policy practice in Mozambique, we argue that low institutional quality is a key barrier to promote increased access to electricity for the poor

    In order to design electrification systems, recent mathematical models solve the problem of location, type of electrification components, and the design of possible distribution microgrids. However, due to the amount of points to be electrified increases, the solution to these models require high computational times, thereby becoming unviable practice models. This study posed a new heuristic method for the electrification of rural areas in order to solve the problem. This heuristic algorithm presents the deployment of rural electrification microgrids in the world, by finding routes for optimal placement lines and transformers in transmission and distribution microgrids. The challenge is to obtain a display with equity in losses, considering the capacity constraints of the devices and topology of the land at minimal economic cost. An optimal scenario ensures the electrification of all neighbourhoods to a minimum investment cost in terms of the distance between electric conductors and the amount of transformation devices.

    Sub-Saharan Africa has the lowest access to electricity in the World. In Senegal, less than 25% of the rural population benefit of electricity service. Solar energy offers an important potential to Senegal with over 3000 h of sunlight a year. This is a real opportunity to generalize the access to electricity. But, the efforts to bridge the gap must be diversified and completed. We approach the problem of rural electrification with a different point of view. Grid expansion and centralized solutions may be adequate for villages with a population organized in high-density of habitations. Small size villages or those with highly dispersed population may need different propositions because of cost. These regions will not be the priority of electrification programs. Furthermore, this rural population is characterized by its low income and saving. Such a conjuncture suggests the opportunity of a service based fees model for access to electricity. On the basis of a fees-for-service model, individual standalone photovoltaic systems may be a more appropriate solution to cover the priority needs of lighting and mobile phones battery charge for telecommunication. We present a pilot project in a village of Senegal to support the model and demonstrate its feasibility. - Highlights: • Rural electrification in developing countries. • Problems of access to electricity in rural areas. • Fees-for-service solution for small villages/highly dispersed population villages. • Situation of Senegal. • Presentation of a pilot project in a small village of Senegal

    The Mariano Marcos State University-Affiliated Non Conventional Energy Center (MMSU-ANEC) in partnership with the Energy Management Bureau-Renewable Energy Management Division, Department of Energy implemented the Barangay Electrification Program (BEP) of the government in the off-grid rural areas at the northern Philippines from 1995-2004 with a common vision of promoting the use of new and renewable energy systems for rural electrification in order to spur development in the far-flung, off-grid rural areas. Such activity of the MMSU-ANEC on BEP used modified and improved Photovoltaic battery charging stations (PVBCS) to energize households and augment their livelihood in collaboration with the local government units and the beneficiaries. Socioeconomic and environmental impacts using long-range energy alternative planning or LEAP software showed that PVBCS are indispensable, feasible, economical, environmental-friendly and sustainable renewable energy resources systems in off-grid areas. Improvement of a locally-made battery charging unit (patent applied at IPO, Manila) which is cheaper and comparable than the imported unit, enabling project implementation strategies in community organizing and lessons learned during the implementation of BEP are also presented. Such improvement of the PVBCS is considered an innovative advancement in renewable energy that can be commercialized towards a sustainable agro-industrial development in far-flung, off-grid rural areas, among other applications for rural electrification and power generation using clean and environment-friendly sustainable technologies.

    1998-01-01

    The electrification of rural communities in the Cote d'Ivoire has progressed more rapidly than any other sub-Saharan nation, principally because of the will of government authorities to eliminate any regional disparities within the country. Out of a total of 8,538 villages, 475 villages had electricity by the end of 1980. This number climbed to 1,068 by 1995 and 1,691 in 1997. Currently, 66 per cent of all citizens of the country have electricity. Much of this effort, at least until 1990, was supported by a strong state-owned electric utility. A limited number of off-grid power generation projects were also undertaken. These projects involved photovoltaic stations, diesel or gasoline powered generating stations and biomass fueled stations. Privatization of the national electric utility in 1990 resulted in significant decrease in the progress of rural electrification. fig

    Solar photovoltaic technologies have for some time been promoted as a cost effective means of rural electrification in developing countries. However, institutional structures resulting in poor maintenance have adversely affected the sustainability of past solar projects. In Fiji, the Renewable Energy Service Company (RESCO) program is the latest attempt to promote solar-based rural electrification in a fee-for-service model, aiming to remove the high upfront capital costs associated with solar technologies and using a public-private sector partnership for maintenance. This paper assesses the program using survey and interview data. Major flaws are identified, relating to incorrect treatment of principal-agent problems, information asymmetries, motivational problems, and resourcing of government agencies. General lessons for fee-for-service solar home system models emerge, including that incentives for stakeholders must take centre stage in designing and administering such programs, and that active government support and ownership are required to make programs sustainable.

    Rural electrification with renewable energy technologies (RETs) offers several benefits to remote areas where diesel generation is unsuitable due to fuel supply constraints. Such benefits include environmental and social aspects, which are linked to energy access and poverty reduction in less-favored areas of developing countries. In this case, multi-objective methods are suitable tools for planning in rural areas. In this study, assessment of rural electrification with renewable energy systems is conducted by means of goal programming towards fuel substitution. The approach showed that, in the Non-Interconnected Zones of Colombia, substitution of traditional biomass with an electrification scheme using renewable energy sources provides significant environmental benefits, measured as land use and avoided emissions, as well as higher employment generation rates than diesel generation schemes. Nevertheless, fuel substitution is constrained by the elevated cost of electricity compared to traditional biomass, which raises households' energy expenditures between twofold to five times higher values. The present approach, yet wide in scope, is still limited for quantifying the impact of energy access improvements on poverty reduction, as well as for the assessment of energy system's technical feasibility.

    Access to affordable, reliable and clean energy is fundamental for poverty reduction and sustainable development; without it, the Millennium Development Goals cannot be achieved. Electrification, along with access to modern cooking fuels and mechanical power, is a catalyst for improvements in the fields of poverty reduction, food security, health, education and gender equality. Nevertheless, 1.3 billion people still lack access to electricity, over 95 per cent living in sub-Saharan Africa or developing Asia and 84 per cent of them living in rural areas. There are many different ways to electrify rural areas, not only with regard to the different technologies used, but also to the types of delivery models applied. Common rural electrification technologies include grid extension, community mini-grids, stand-alone household systems, multifunctional platforms, and central charging stations with battery banks. This report will focus on the delivery models used for community mini-grids, as there is evidence to show that mini-grids can be one of the cheaper forms of electrification (on a per unit basis, calculated over the system's lifetime) and also potentially offer a 24 hour AC service that can power a wide range of appliances.

    From as early as the 1880s until as late as the 1970s, electrical power served as a critical tool for bringing America's diverse western communities into an urban industrial era. This study examines the process of electrification in three demographically diverse rural regions of Eastern Arizona. These three regions include the valleys of the Southeast, the White Mountains, and the Navajo Reservation to the north. While federal programs aided rural residents, local and regional factors determined the timing and nature of electrification and its impact. Access to electricity depended upon economics and technological advances, as well as a combination of local community and regional characteristics such as location, landscape, demographics, politics, and culture. At the turn of the century, electricity, with its elaborate and extensive infrastructure of wires, towers, and poles, emerged across America's cultural landscapes as the industrial era's most prominent symbol of progress, power, and a modern, urban lifestyle. Technological innovations and mechanization flourished, but primarily in the urban areas of the Northeast. People living outside concentrated settlements, of all ethnic backgrounds, had few hopes for delivery due to the cost of building power lines to a limited market. Arizona's rural population has historically been ethnically diverse, and its landscape varies from desert valleys to mountains of alpine forest. The federal government owns much of the land. Aided by federal guidance and funding sources like the New Deal's Rural Electrification Administration (REA), the existing rural communities took the initiative and constructed electrical systems specific to their local and regional needs. While products of the communities that built them, these systems symbolized and defined newly urbanized regions within the context of old rural landscapes, lifestyles, and traditions. In some ways the rural electrification process urbanized rural Arizona. The

    Full Text Available Abstract In this study clustering algorithm was developed to optimize electrification plans by screening and grouping potential customers to be supplied with electricity. The algorithm provided adifferent approach in clustering problem which combines conceptual and distance-based clustering algorithmsto analyze potential clusters using spanning tree with the shortest possible edge weight and creating final cluster trees based on the test of inconsistency for the edges. The clustering criteria consists of commonly used distance measure with the addition of household information as basis for the ability to pay ATP value. The combination of these two parameters resulted to a more significant and realistic clusters since distance measure alone could not take the effect of the household characteristics in screening the most sensible groupings of households. In addition the implications of varying geographical features were incorporated in the algorithm by using routing index across the locations of the households. This new approach of connecting the households in an area was applied in an actual case study of one village or barangay that was not yet energized. The results of clustering algorithm generated cluster trees which could becomethetheoretical basis for power utilities to plan the initial network arrangement of electrification. Scenario analysis conducted on the two strategies of clustering the households provideddifferent alternatives for the optimization of the cost of electrification. Futhermorethe benefits associated with the two strategies formulated from the two scenarios was evaluated using benefit cost ratio BC to determine which is more economically advantageous. The results of the study showed that clustering algorithm proved to be effective in solving electrification optimization problem and serves its purpose as a planning support tool which can facilitate electrification in rural areas and achieve cost-effectiveness.

    The majority of the population in Sudan still lives in the rural areas where they still suffer from problems of poverty, unemployment, high rates of illiteracy, poor health services, shortage of water, and migration to urban areas. Development plans within decentralization efforts taking place in the country should give great importance to rural development by activating rural productive sector comprising agriculture and small scale industries. Rural electrification (RE) can play an important role as akey infrastructure for rural development, and could change the rural communities socially and economically to the better. RE also have desirable environmental impacts when substituting polluting and scare fuels such as petroleum fuel and fuel wood by electricity. Compared with urban electrification, RE is characterized by scattered consumers, low demands, and low load factors. This results in high connection costs of electricity per consumer, and high unit (Kwh) cost. In Sudan, rural electricity demands range from small industries of 50 or industries and individual farms. To bring electricity supply to these different categories of rural consumers at a reasonable investment cost requires proper planning. It needs regular data collection and updating, selection of appropriate technology, project formulation, financing implementation, management, and follow-up. The Sudan National Electricity Corporation (NEC), gives priority to the generation and transmission of electricity to the big urban and industrial areas. NEC treats RE as low priority to which resources are only devoted after the more urgent needs of the urban and industrial consumers not impossible, for a utility like the NEC to construct, operate, and maintain a large number of small scale projects in rural areas. To enable RE to play an effective institution with RE as its primary objectives is very crucial. This paper aims to highlight the importance of RE and its impacts on the rural inhabitants socially

    The challenges of providing electricity to rural households are manifold. Ever increasing demand-supply gap, crumbling electricity transmission and distribution infrastructure, high cost of delivered electricity are a few of these. Use of renewable energy technologies for meeting basic energy needs of rural communities has been promoted by the Governments world over for many decades. Photovoltaic (PV) technology is one of the first among several renewable energy technologies that was adopted globally as well as in India for meeting basic electricity needs of rural areas that are not connected to the grid. This paper attempts at reviewing and analyzing PV literature pertaining to decentralized rural electrification into two main categories - (1) experiences from rural electrification and technology demonstration programmes covering barriers and challenges in marketing and dissemination; institutional and financing approaches; and productive and economic applications, (2) techno-economic aspects including system design methodologies and approaches; performance evaluation and monitoring; techno-economic comparison of various systems; and environmental implications and life cycle analysis. The paper discusses the emerging trends in its concluding remarks. (author)

    This thesis has for object the evolution of the economic optimum in the electric industry under spatial equity constraint that present a strong spatial heterogeneity of its supply conditions. One analyses the evolution of the rural electrification regime in France both in terms of economic and social efficiency. We examine the rationality of extending the sectoral optimization under equity constraint to the rationalization of electricity end-uses in the heterogeneous space of rural electricity supply. To this question are given two responses. The firsts pertains to modify the incentives in the institutional regime of rural electrification so the MDE may be integrated in the strategies of rural electrification syndicates. One inspire from incentives mechanisms of the anglo-saxon DSM practice. The second is statistical zoning method of demand and distribution grid whose object is to localize action basins for large scale MDE projects. (author)

    An estimated 13% of Ethiopia's population has access to electricity. Almost all electrified centres are urban, with rural areas as well as most small rural towns largely unelectrified. Rural electrification (RE) thus remains a major challenge to the power sector of Ethiopia. The national power utility (EEPCO) has traditionally been assigned the task of electrifying rural demand centres. EEPCO has, however, concentrated on the more developed and profitable urban areas. The objective of this article is to present the findings of a study that examined whether the ongoing power sector reforms in Ethiopia can attract private investment in RE as an alternative to the sole reliance on EEPCO. Initial findings of the study indicate that private investment in RE can be enhanced with some improvement in the legal and regulatory provisions, along with extension of technical assistance from EEPCO to private investors.

    Rural electrification (RE) can be modelled as a multifactorial task connected to a large number of variables: decision makers need to choose the appropriate options by considering not only the techno-economic competitiveness but also socio-cultural dynamics and environmental consequences, making the task intricate. Many rural electrification projects have failed due to lack of attention to the issues beyond financial and technical dimensions. This paper presents a standardized approach for decision making concerning the extension of electricity services to rural areas. This approach first determines whether the supply provision should be grid expansion or off-grid on the basis of levelized cost of delivered electricity. If the grid expansion is found nonviable over off-grid options then a multicriteria decision aiding tool, SMAA-2 (Stochastic Multicriteria Acceptability Analysis), will evaluate off-grid technologies by aggregating 24 criteria values. While applying this approach, the delivered costs of electricity by the grid in remote areas within the 1–25 km distances vary in a range of 0.10–7.85 US$/kW h depending on the line lengths and load conditions. In the off-grid evaluation, the solar PV (photovoltaic) and biogas plants are found as the most preferable alternatives with 59% and 41% acceptability in their first rank, respectively. - Highlights: • Rural electrification involves a large number of socio-cultural issues in addition to technical and environmental considerations. • Decision makers need to choose the appropriate options by considering many criteria. • Many off-grid projects failed due to noncomplying of societal issues. • Multicriteria based decision choice can safeguard the projects from these issues. • SMAA analysis can select the alternatives based on merits

    This paper investigates the political and institutional factors that have influenced the success of the Senegalese Rural Electrification Action Plan (Plan d'Action Sénégalais d'Électrification Rurale, PASER). PASER is of interest because its innovative design attracted extensive offers of finance from donors and independent power providers, however it has had limited effect on electrification levels. This paper examines PASER's progress and problems in detail, with the aim of informing rural electrification policy internationally. An extensive literature review was combined with 26 semi-structured stakeholder interviews, to produce a snapshot of the Plan's status after its first decade of operation. PASER's experiences are compared with other reform-based rural electrification initiatives across Sub-Saharan Africa. PASER has faced significant institutional and political barriers, with delays arising from organisational opposition, inconsistent ministerial support, protracted consultations and the inherent challenges of implementing an innovative policy framework in a country with limited institutional capacity. The development of human and institutional capacity has been compromised by inconsistent political commitment. Such experiences mirror those of electrification initiatives across Sub-Saharan Africa. Whilst PASER's successes in garnering external support and fundraising are noteworthy and won praise from early reviews, in terms of delivery the Plan has failed to resolve common institutional barriers. - Highlights: • Factors influencing the Senegalese Rural Electrification Action Plan are investigated. • 26 Stakeholder interviews inform a review of the Plan after 10 years of operation. • The Plan has attracted extensive finance, but installations are severely delayed. • The delays are found to be largely the result of institutional and political barriers. • These barriers mirror the experiences of electrification

    During the last 20 years Mexico has been fertile ground for rural projects using renewable energy technologies. In many cases, however, sustainability aspects were either improperly handled or essentially ignored. Such was the case, for instance, with solar thermal water pumping projects, solar water desalination, and even complete 'solar towns'. Painful but important lessons were learned from such failed projects. Now, sustainability is the focal point of a current rural electrification programme with renewable energy. As of this writing, over 24,000 individual home photovoltaic lighting systems have already been installed in different regions of Mexico; another 12,000 systems are estimated to have been installed in rural areas as a result of private commercial activities; seven village-size hybrid systems (photovoltaic-wind and photovoltaic-wind-diesel) have also been implemented. With this, the Mexican renewable energy rural electrification programme stands among the largest programmes of its kind in the world today. The question of the programme's sustainability has been a major concern at the Electrical Research Institute of Mexico (IIE), where activities have been under way since the start to lend it technical support. The lessons learned in the process will be discussed in this article. (author). 8 refs

  18. Les cooperatives et l'electrification rurale du Quebec, 1945--1964

    Science.gov (United States)

    Dorion, Marie-Josee

    Cette these est consacree a l'histoire de l'electrification rurale du Quebec, et, plus particulierement, a l'histoire des cooperatives d'electricite. Fondees par vagues successives a partir de 1945, les cooperatives rurales d'electricite ont ete actives dans plusieurs regions du Quebec et elles ont electrifie une partie significative des zones rurales. Afin de comprendre le contexte de la creation des cooperatives d'electricite, notre these debute (premiere partie) par une analyse du climat sociopolitique des annees precedant la naissance du systeme cooperatif d'electrification rurale. Nous y voyons de quelle facon l'electrification rurale devient progressivement, a partir de la fin des annees 1920, une question d'actualite a laquelle les divers gouvernements qui se succedent tentent de trouver une solution, sans engager---ou si peu---les fonds de l'Etat. En ce sens, la premiere etatisation et la mise sur pied d'Hydro-Quebec, en 1944, marquent une rupture quant au mode d'action privilegie jusque-la. La nouvelle societe d'Etat se voit cependant retirer son mandat d'electrifier le monde rural un an apres sa fondation, car le gouvernement Duplessis, de retour au pouvoir, prefere mettre en place son propre modele d'electrification rurale. Ce systeme repose sur des cooperatives d'electricite, soutenues par un organisme public, l'Office de l'electrification rurale (OER). L'OER suscite de grandes attentes de la part des ruraux et c'est par centaines qu'ils se manifestent. Cet engouement pour les cooperatives complique la tache de l'OER, qui doit superviser de nouvelles societes tout en assurant sa propre organisation. Malgre des hesitations et quelques delais introduits par un manque de connaissances techniques et de personnel qualifie, les commissaires de l'OER se revelent perspicaces et parviennent a mettre sur pied un systeme cooperatif d'electrification rurale qui produit des resultats rapides. Il leur faudra cependant compter sur l'aide des autres acteurs engages

    Pico hydro power is a renewable energy system which has the potential to provide millions of rural people world-wide with a cheap, sustainable source of electricity. The development of new, cost-reducing approaches, including local manufacture and implementation in developing countries, has increased the accessibility of this technology to large numbers of people. The new approaches are investigated and some of the present constraints to wider adoption of this technology are analysed. (Author)

    This study is motivated by the goal of achieving ‘Universal Energy Access’ by 2030 and looks at electricity access for rural households in the South Asian region. The ‘MESSAGE-Access’ model is employed to assess the cost effectiveness of centralized and Decentralized Distributed Generation (DDG) technologies. Delivery mechanisms are modelled to include mini-grid and stand-alone systems and the analysis includes an estimation of rural household electricity demand from lighting and appliances. We assume two future demand scenarios with a ‘minimum threshold’ and a ‘higher threshold’ of electricity consumption of 65 and 420 kW h per household per year, respectively. We find that the cost of delivering electricity by centralized generation and grid distribution is up to four times the cost of stand-alone and mini-grid DDG options in the case of ‘minimum threshold’ demand scenario. These results are robust to alternate assumptions regarding costs of technologies. We also estimate that public subsidy bill for kerosene can be substantially reduced if all households switch to electricity as their primary source of lighting. Thus, promoting DDG options can reduce capital investments needed to meet access goals significantly and have an important role to play, in meeting the goal of universal electrification by 2030. - Highlights: ► We model and assess DDG options for rural electrification in South Asia. ► Particularly, when demand is low, off-grid and mini-grid are least cost options for electrification. ► DDG options can be 3–4 times cheaper than extending a central grid. ► Kerosene lighting is up to 6 times as expensive as electric lighting. ► If electricity replaces kerosene for lighting, large subsidy savings can be realized.

  1. Mini hydraulic energy: An alternative for rural electrification

    1992-01-01

    Within the activities of alternative energy group of the faculty of engineering of the university of Antioquia, the development of prototypes is included, of using the non conventional sources for electrical energy production and then satisfy urgent necessities in rural home isolated from the national energy network. In the eastern region of Antioquia, a great hydraulic resource was found with large rivers, stream and water sources near houses, that don't have possibilities of a rural energy network in a near or faraway future, because of its isolation and low economic capacity. A small hydraulic pico generator was developed for this region with the following characteristics: very small dimensions, low weight, compact and integrated design, easy manufacturing in great volumes with low cost. in its operation it loads one or more stationary batteries that provide electricity to a residence, being used in: illumination, communications and some home appliances. By its operation capacity of 24 hours per day, it would compete in advantage with the photovoltaic panel systems used in isolated regions. Advantages of these plants: It is property of the user; zero expenses in administration and operation, low environmental impact (elimination of dams), protection of micro river basins and automatic operation

    This paper discusses the overdue change in the processes of rural electrification by means of renewable energies. The actors involve in these processes have failed to contemplate every dimension of this issue: Social, Institutional, Technological, Economical, Financial and Political. We will account for the reason why the concept of sustainability must be closely related to that of local socioeconomic development. Rural electrification must be a vector for social development. It is in this context that it cannot depend exclusively on the market and its actors, but it must be immersed within rural development planning. For this new paradigm to work properly, donor agencies -mainly- should understand the dynamics of socioeconomic development, contemplating the different local characteristics of small rural communities; they should provide genuine financial support within an adequate regulatory framework and active participation should be encouraged, both of the local community and of local enterprises. The sustainability of these initiatives is determined not only by the consideration of the dimensions above but also by the creation of labour possibilities or lack thereof. (authors)

  3. Emerging regulatory challenges facing the Indian rural electrification programme

    2009-01-01

    The purpose of this paper is to present and analyse the regulatory issues emerging from the newly launched programme of rural electricity access in India. We focus on two broad areas, namely regulatory issues related to the organisation/structuring of the activities and issues related to subsidy and tariffs. The paper looks into the alternative organisational arrangements being used by the programme and identifies problem areas through a responsibility mapping. The tariff principle being followed by the programme is then analysed considering the alternative organisational forms and issues related to such pricing policies are identified. Possible alternative pricing options are then suggested. The paper finds that while the franchisee model is an innovative idea, it raises issues that the regulators should be concerned with. The programme has so far relied on the simplest franchisee model because of its ease of implementation but a transition to more complex alternatives would require careful considerations

    A special early excerpt of the IEA's World Energy Outlook 2010 focusing on energy poverty indicates that 1.4 billion people don't have access to electricity, 85% of which live in rural areas. The social, economic and local environmental benefits from having access to electricity are well-known, including less indoor pollution, less spending on fuel, less stress on the local eco-system, expansion of the productive and social hours of the day, cooling for food and medicine, and enabling education in the evening hours. This study examines options for rural electrification in Mozambique, where 89% of the population doesn't have access to electricity. Conventional and alternative options are compared with respect to energy, environmental, and economic consequences. The research methodology follows a knowledge-based approach, which allows for a comprehensive and holistic evaluation of how different rural electrification options affect the society in general, and the economy in particular. The paper presents an innovative techno-economic model for Mozambique that evaluates how different stakeholders and economic sectors are influenced by conventional and alternative options for rural electrification. The study offers new qualitative and quantitative empirical data, which support a significantly better understanding of how different rural electrification strategies are impacting society. (orig.)

    The goal of providing universal energy access to all by 2030 under the UN-led SE4ALL initiative calls for new and innovative solutions to rural electrification and is fuelling the recent interest in mini-grids. Mini-grid solutions are emerging as a third alternative to rural electrification, coming...... between the option of large-scale grid extension and pico-scale stand-alone solutions like solar home systems or solar lanterns. International expectations of mini-grids are high, with the International Energy Agency suggesting that they will play a significant role in reaching the goal of universal...... electrification and the challenges identified in the literature, the study concludes by proposing three avenues for further research.

    Prior to that, as an introduction, I'd like to tell you a bit about Shell solar and rural electrification from their perspective. If I could add something to the speech of Mr. Holm, I would gladly do that. Thirdly, I'd like to address the South African rural electrification market. I'd like to talk a bit about the system we have on the offering called the ''Powerhouse'' system, give you the Eastern Cape project status, and draw some conclusions with you. ''Jenza'' is a Zulu word, which means ''just do it - get on with it''. In a number of speeches today, I heard the words ''demonstration'', ''research'', ''study'', etc. I don't think the two billion people that have been on several occasions are waiting for more studies; I think they are waiting for initiatives - to ''just do it'' on a large scale. As Mr. Gehr pointed out, in Morocco there is a program of 200,000 customers, and they're running it.

    This paper analyzes the work done in Cuba over the last years in the field of photovoltaic, from its R and D and Industrial capacities to the Rural Electrification Program. Based on this work a Development Program for the PV industry is proposed, which is defected towards the integration of all necessary factors that will ensure a sustainable Rural Electrification Program. This program is divided in 5 main stages: 1. Import of solar cells and other elements for the assembly in Cuba of modules and diverse system components (1995-2005). 2. Production of solar cells from imported wafers (1997-2005). 3. Production of monocrystalline silicon wafers from imported plycrystalline silicon (1998-2005). 4. Production of polycrystalline silicon from Cuban silica sand (2000-2005). 5. Development and introduction of new technologies for the production of solar cells (2000-2005). The combination of the PV Development program and the Rural Electrification program will guarantee the supply of electricity to 100% of the Cuban population, and at same time accelerate the technological, industrial and research infrastructure on which a large scale national PV industry would be supported. The implementation of such a program would also make cost on the National Electrical Grid (NEG), avoiding the need for new generation facilities based on fossil fuels.

    The lack of resources and the new scenery of private utilities turn necessary to look for the ways that allow to illuminate the rural zone. Several international papers show the involvement of different segments of the society as being a viable alternative to execute this goal. This paper analyses the experience of Sao Paulo in the practice of a program of rural electrification in which the society is involved. The model, the operational difficulties and the alternatives made to agile program are appraised. The main conclusion is that, in spite of the difficulties, the model in which the society is included is a viable alternative to solve the subject of the lack of energy in the countryside. (author)

    Solar home systems are typically used for providing basic electricity services to rural households that are not connected to electric grid. Off-grid PV power plants with their own distribution network (micro/minigrids) are also being considered for rural electrification. A techno-economic comparison of the two options to facilitate a choice between them is presented in this study on the basis of annualised life cycle costs (ALCC) for same type of loads and load patterns for varying number of households and varying length and costs of distribution network. The results highlight that microgrid is generally a more economic option for a village having a flat geographic terrain and more than 500 densely located households using 3-4 low power appliances (e.g. 9 W CFLs) for an average of 4 h daily. The study analyses the viability of the two options from the perspectives of the user, an energy service company and the society.

  15. Standardized small diesel power plants for rural electrification in Tanzania

    Holmqvist, A.; Soerman, J.; Gullberg, M.; Kjellstroem, B.

    1993-01-01

    This study focuses on small townships where the forecasted power demand stays below 500 kW during the ten first years. Case study calculations were made where two hypothetical load centres form the base. Each load centre is assumed to be supplied by two alternative standardized diesel power plants. One option is a power plant consisting of two medium speed (750 rpm) generator sets, one always on stand-by. Alternatively, a power plant consisting of three high speed (1500 rpm) generator sets is evaluated for each hypothetical load centre. The calculations clearly show that the high speed, three unit option comes out cheaper than the two unit, medium speed option in all the considered cases. The fuel costs per kWh generated are almost the same in all the cases studied, i.e. between 6 and 7 US cents. The medium speed engine tends to consume more fuel per kWh generated than the high speed, as it runs more often on part load. Consequently, the fuel costs will be slightly higher for this option. It is also of interest to compare the plant failure rate of the two options. In this study no proper probability evaluation has been made, but some general reflections can be worth considering. The availability of spare parts in Tanzania is doubtful. Many small diesel power plants presently operating have to wait indefinitely, when a failure appears that requires spare parts. As long as the individual sets have the same, or nearly the same failure rate, a three unit plant has lower probability for total loss of generating capacity than a two unit plant. The main conclusion of this evaluation is that for electricity generation in rural Tanzanian villages, power plants with three small, high speed generator sets are preferable to plants with two, medium speed generator sets. A power plant made out of small sets requires less capital, consumes less fuel and is not as likely to loose its generating capacity totally. 16 refs, 10 figs, 21 tabs

    Utilization of renewable energy technologies remains one of the major energy policies throughout the world. These technologies are proven to be successful for electrifying rural communities, especially in developing countries. Realizing the benefits of renewable energy sources, the Government of Nepal has initiated the production and distribution of renewable energy technologies in recent years, mainly to electrify rural communities. Although these technologies are suitable for providing electricity in isolated and remote rural areas, their implementation programs have not been successful as expected. This review provides broad-spectrum view about the energy situation in Nepal and highlights the current policies and subsidies for the optimal utilization of renewable energy resources in isolated and poor rural communities. In addition, major promotional barriers for their implementation in Nepal have been discussed. - Highlights: ► Nepal has enormous potential of renewable energy sources. ► Till date only small fraction of renewable energy sources has been exploited. ► However, renewable energy technologies seem to be promising options for rural electrification.

    This work presents the concept of a wind-diesel hybrid system for the electrification of a small rural community in the Northern Region of Brazil, which can be used in many other places with similar characteristics. The system consists of two small diesel units and two wind turbines, one of which was designed and developed as a prototype with the purpose of gaining some insight in the field of wind turbine technology. Some considerations about small communities of the Northern Region of Brazil, and about electrification concepts are also made.

  18. A case study of small hydro and grid extension for rural electrification alternatives and complementarities

    Tebicke, H.L.; Mariam, H.G.

    1990-01-01

    This paper reports that rural electrification in Eastern and Southern African Countries (ESAC) has so far been based largely on stand-alone diesel electric generating plant or on the extension of high-voltage transmission grids fed by large hydro and/or thermal electric generating stations. The alternative of furnishing supply at modest investment and competitive cost from a nearby small- hydro plant has rarely been considered in those countries of the sub-region that have ample hydro-power resources. All countries in the sub-region (except Angola) import petroleum and/or petroleum product supplies, as well as all hardware for electricity supply and utilization. As a result, in most countries an acute shortage of foreign exchange severely hampers implementation of rural electrification schemes. This should turn attention increasingly to strategies which are less capital-intensive and less dependent on foreign exchange, such as small-hydro plants, where the resource is located near to rural demand. Increasing the local content of small-hydro project implementation has paid off in recent years, considerably reducing costs in a number of Asian and Latin American projects. Local contributions have taken the form of resource assessment at a particular site, design, construction works, and fabrication of relatively simple components of power plant such as hydraulic equipment, low pressure penstocks and gates, as well as simpler types of turbines (e.g., the Banki type). Inadequacy of indigenous technical capacity to make similar local contributions in the ESAC has meant that the few recent small-hydro projects have relied on importing both expertise and equipment. The high costs resulting have frequently fueled arguments against pursuit of small-hydro projects

    The objective of this project is to redefine the algorithm of wind-diesel hybrid system implemented in IntiGIS. This methodology was developed by CIEMAT for the evaluation of rural electrification projects, comparing different renewable and conventional technologies based on their LEC or equivalent electrification cost. The analysis considers the social and geographical particularities of the study area. The core of the new model is the definition of renewable fraction in the wind-diesel hybrid system. To this end, it was assumed that the fraction of renewable will depend, first of all, of the wind speed. In this case, the objectives were to find a relationship between the renewable fraction and wind speed, expressed as a function, and also trying to demonstrate the influence of other parameters such as fuel price and consumption. The methodology used to achieve these objectives was to use HOMER to simulate technology and size of system components in order to obtain the optimal fraction renewable scenarios. Next, we examined how it varied with wind speed; we assessed the influence of other parameters and, finally, it is represented as a function of wind speed. After the redefinition of the algorithm, the changes were planned for inclusion in IntiGIS and tests were performed to validate the new model. (Author)

    Full Text Available The power situation in rural India continues to remain poor with around one-third of the rural population without access to any form of electricity. The consequence of which is kerosene being used as a major source of lighting for un-electrified households as well as households with intermittent access to electricity in rural areas. While grid based electrification has been the most common approach, decentralized renewable energy options especially, solar PV systems have also been adopted as a cost effective mode of electrification. This paper presents the results of socio-technical assessment of solar photovoltaic interventions namely, solar home systems, solar mini-grid and solar AC pico-grids, which have been used to electrify selected villages in Sundarbans region of India. The study is focused on technical, financial, and institutional aspects along with the social impact assessment of PV based electrification in the Sundarbans region. The results of the study elucidate that, in general, the impacts of the solar PV solutions used for electrification have been largely positive, especially benefits of reduced kerosene consumption, ease in studying and cooking and reduced health effects. The study also finds that technology is not the only factor on which the viability of a program depends, but institutional and financial aspects also play a significant role. The need of the hour is to develop a strong institutional framework and enabling policies for achieving higher success rates in PV programs.

    In spite of all advances made by modern technology, there are still regions which remoteness has made electrification of poor rural localities very difficult or impossible. The only practical solution for these localities is a local, decentralized form of electrical generation, such as solar energy. Based on its availability and potential, together with the scientific and technical advances made in photovoltaic conversion, solar energy is an alternative which is viable for many rural areas in developing countries. The technology has matured sufficiently, but in its application there is still a need for systematization for experiences, especially in the areas of planning and management. The present work deals with a project carried in the community of Chimboata, Chimboata department, Bolivia. The implementation aspects are analysed and the implementation methodology described. Finally, the forms of managing and funding this type of systems are analysed. (author)

    Universal access to electricity is deemed critical for improving living standards and indispensable for eradicating poverty and achieving sustainable development. In 2003, the ‘Luz para Todos’ (LpT—Light for All) program was launched aiming to universalize access to electricity in Brazil. The program focused on rural and isolated areas, also targeting to bring development to those regions along with electrification. This paper evaluates the results of the LpT program in improving socio-economic development in the poorest regions of Brazil. After an initial qualitative analysis, an empirical quantitative assessment of the influence of increased electrification rates on the components of the Human Development Index (HDI) is performed. The empirical results of this study showed that electrification had a positive influence on all dimensions of the HDI, with the education component having the strongest effect. Although complementary policies were needed to achieve this, results show that electricity access is a major requirement to improve quality of life.

    The present work is based on the sizing method by means of simulation of the photovoltaic systems energy behavior, applied to rural electrification in regions far from the electric net. The denomination of infra/over sized systems is made and a requested analysis of one particular case is exposed, where it is considered two energy options of different qualities of electric service and the economic valuation of each option is requested, with its corresponding argument. The quality level is established with the fault index in the electricity service for energy lack in the batteries, besides the quantity of energy autonomy days of the system. As conclusions, in infra-sizing conditions systems, and with established quality level of service, multiple sizing solutions exist, and under certain conditions, not always the systems with more quality level, are those of more cost, as well as the presence of a minimum cost in the sizing can be obtained by simulation methods.

    2012-01-01

    2012 has been declared the “International Year for Sustainable Energy for All” by the UN. While Africa remains the most ‘underpowered’ continent, the prognosis for a brighter future is looking good, as key stakeholders (governments, private sector, civil society, and the donor community) have mobilized at an unprecedented scale to experiment with new policies, regulatory frameworks, and business models to rapidly upscale access to sustainable energy. The top-down, central grid expansion approach to increasing electricity access is very capital intensive and yet has gained considerable momentum at the expense of lower cost options that utilize decentralized off-grid solutions. A decentralized bottom-up approach could also use indigenous renewable energy sources and foster more significant linkages with livelihood opportunities in the rural un-served territories. This paper evaluates the emerging experiments through the lenses of C.K. Prahalad's “bottom of the pyramid” theory and Clayton Christensen's “disruptive technologies” perspective. Three front-runner initiatives involving new business models, innovative technologies, and institutional capacity building will be analyzed. In addition, the paper examines a regulatory policy initiative designed to stimulate clean energy investments in Ghana. Though the examples are all from Ghana, they illustrate general challenges to sub-Saharan Africa as a whole. - Highlights: ► An analysis of innovative electricity access case studies from Ghana. ► Off-grid electrification options are keys to expanding electricity access in Africa. ► Base of the pyramid strategies for rural electrification has a niche in Africa. ► International collaboration will be crucial to achieve universal electricity access.

    The municipality of Santarem in the lower Amazon river is the main center in the western region of the state of Para with a population of 274.285 inhabitants, with 31.633 of them living in the rural zone, where only 1.060 rural costumers have access to regular electricity service from the utility provider. This incipient coverage of electricity service in the rural zone urged the local population to look for alternatives. This was found in the use of the hydraulic potential of creeks and rivers with rapids and waterfalls to implement pico and micro hydroelectric plants. So since 2001, 44 pico and 12 micro hydropower plants were installed in the municipalities of Santarem, Belterra and Uruara in the state of Para by local entrepreneurs and communities to attend their basic electricity needs. These systems attend approximately 580 families with a total installed capacity of more than 700 kVA . The consolidation of this technological alternative induced the Regional Superintendent of the Institute for Colonization and Land Reform (INCRA ) and the Municipality of Santarem to elaborate a project to attend the land reform settlements in the region. This led to the installation of 6 micro hydropower (MHP) with a total installed capacity of 820kVA and a 252 km distribution network to attend 1.630 families in the settlements of Moju and Corta Corda. The purpose of this paper is to present the MHP's installed in the region and to show the contribution of these units in the rural electrification of rural settlements in Santarem. The paper discusses also the management model of these units. The survey's methodology consisted in the systematization of project data from the plant builder, INCRA and the municipality. The information was obtained from the official bibliography from the local actors and complemented by field surveys with interviews and observation.

    South and Southeast (S and SE) Asian countries are characterized as being densely populated and having low access to electricity. In faet, about 59.2% and 37.8%, respectively, of the total population do not have access to electricity. Moreover, rural areas of the subregion also suffer from low electrification levels - only 30.1% in South Asia and around 51% in Southeast Asia compared to 68.2% and 89.9% in the urban areas, respectively. Some of the countries in the sutregion are at various stages of economic reforms, but all of which are moving from a centrally or heavily regulated economy to a more market- driven economy. The economic reforms in S&SE Asia have also permeated the power sector. A cursory look at the evolution of the electricity sector in some countries in the subregion reveal that the reforms undertaken in electricity sector during the early years were primarily aimed at addressing the issues of providing electricity to the people and then increasing electricity coverage. Later, in order to increase electricity coverage, institutions were established or 'carved out' from existing institutions to undertake national electrification programs to increase electricity coverage. In most cases, the electricity sectors remained under vertically integrated monopolies responsible for generation, transmission, and distribution but internal restructuring was undertaken for the purpose of increasing electricity coverage, especially in rural areas. In recent years, the reforms focused on fundamental major restructuring of the sector: separation or unbundling of the generation, transmission, and distribution; change in ownership from public to private sector, or at least increase in private sector participation by deregulating generation; and restructuring of electricity tariffs and gradually removing subsidies to better reflect economic or true costs of electricity supply. All these changes have geared towards increasing economic efficiency of the sector

    In spite of the intention of governments to increase the use of renewable energy in electricity supply, particularly the use of solar photovoltaic (PV) for energy poverty reduction in rural and peri-urban areas of Africa, there is relatively little information on how solar PV electrification impacts on energy poverty reduction. Therefore, there is a gap in the literature and hence the need for continuous research. Using Ghana as a reference country, the historical trend, donor cooperation and other aspects of solar PV rural electrification are discussed. The paper illustrates the intersectoral linkages of solar PV electrification and indicators on education, health, information acquisition, agriculture and micro-enterprises. It also reviews sustainability related issues including costs and market barriers, subsidies, stakeholders involvement, political and policy implications, which are critical factors for sustainable market development of solar PV and other renewables. Finally, a common framework is developed to provide a basic understanding of how solar PV electrification impacts on energy-poverty. This framework provides a structure of the interrelated concepts and principles relevant to the issues under review. (orig.)

    Worldwide, an estimated 1.5 to 2 billion people do not have access to electricity, including 100 million in the Latin America region. Depending on the country, 30 to 90% of this unelectrified Latin American population lives in rural areas where geographic remoteness and low energy consumption patterns may preclude the extension of the conventional electricity grid. Women are heavily impacted by the energy scarcity given their role as primary energy procurers and users for the household, agricultural and small industrial subsectors in developing countries. As a result, women spend disproportionately more time engaged in energy-related activities like carrying water and searching for cooking fuel. This paper describes the use of decentralized renewable energy systems as one approach to meet the energy needs of rural areas in Latin America. It outlines the advantages of a decentralized energy paradigm to achieve international development goals, especially as they relate to women. The paper studies Enersol Associates, Inc.'s Solar-Based Rural Electrification model as an example of a decentralized energy program which has merged energy and development needs through the local involvement of energy entrepreneurs, non-governmental organizations and community members.

    Rapidly increasing demands and requirements for access to electricity throughout the remote areas of Indonesia coupled with annual subsidies in excess of $500 million of dollars for rural electrification have forced the Government of Indonesia to search for alternatives to the conventional utility model for rural electrification. In 1992-1993 a study was conducted in collaboration with the Government of Indonesia`s Agency Application and Assessment of Technology (BPPT) and the national power utility, PLN to support the search for sustainable solutions for electrification of remote communities. This study produced a New commercial model for electrification of off-grid rural communities in Indonesia with utility quality electricity services. This new model is characterized by the use of new technologies for power generation, distribution, and sales of electricity. Key to the success of the new model are renewable energy-based hybrid power plants and the use of flexible, on-demand electricity dispensing meters. Estimated fees for electricity service are based on the current amounts now being paid by rural households for kerosene, candles and battery services at different income levels. The study showed that most rural households are willing and able to pay additional amounts for reliable, utility grade electricity for valuable services, such as better lighting, TV entertainment and for productive (economic) uses during daytime hours. A financial assessment was conducted for investments in hybrid power systems for off-grid communities with revenues generated on the basis of market fees, and collected through new technology for electricity purchase and prepayment on a commodity basis. The assessment demonstrates that this approach would provide superior electricity services on a full-time basis, with little or no subsidy required during the three- to five-year commercialization phase, and with profitability as an achievable goal in the full commercial phase.

    Three rural electrification options are analysed showing the cost optimal conditions for a sustainable energy development applying renewable energy sources in Africa. A spatial electricity cost model has been designed to point out whether diesel generators, photovoltaic systems or extension of the grid are the least-cost option in off-grid areas. The resulting mapping application offers support to decide in which regions the communities could be electrified either within the grid or in an isolated mini-grid. Donor programs and National Rural Electrification Agencies (or equivalent governmental departments) could use this type of delineation for their program boundaries and then could use the local optimization tools adapted to the prevailing parameters.

    Following the democratic transition in South Africa in the early 1990s the government has implemented a widespread electrification programme, as well as introduced a free basic electricity allowance as a means of poverty alleviation. Yet there are limited longitudinal studies on the impacts of the introduction of electricity on the patterns of household energy use, and even more so in the neglected rural sector. This study reports on the patterns of household energy use in five rural settlements in 1991 and again in 2002. Results indicate a changing pattern of energy use for lighting and powering entertainment appliances, more specifically from dry-cell batteries and paraffin to electricity. Yet for thermal needs, most notably cooking, fuelwood has remained the most widespread fuel, and the amount used per month has not changed, despite increasing scarcity of wood in the local environment. There has been an increase in the proportion of households purchasing fuelwood as opposed to collecting their own. Overall, the mean total number of fuel types used per household has increased, indicating that electricity is simply viewed as an additional energy, rather than an alternative. Yet, electricity accounted for approximately 60% of expenditure on energy sources in 2002, despite the government's policy of a free basic allowance of 5-6 kWh per month. This has implications for energy supply costing, as well as the poverty alleviation dimensions of the whole programme

    A comprehensive survey is carried out in Kendu Bay area of Kenya to determine electrification patterns of a typical rural sub-Saharan Africa community and to determine the reasons behind such energy choices. The data from the survey is used to build a transition probability matrix (TPM) for different electrification states for Kendu Bay households. The TPM and the survey data are used to model temporal diffusion of PV systems and PV-based communal (mini/micro) grids in the area. Survey data show that majority of Kendu Bay residents shun the national grid due to high connection fees, unreliability of the system, and corruption; people who can afford-to choose small solar home systems for their basic electricity needs. Without any government policy intervention or help, simulation results show that once 100% electrification status has been achieved in Kendu Bay, only 26% of the residents will be found to be electrified through the national grid alone; the majority (38%) will be electrified through PV-based communal grids while the remaining 36% will be electrified through grid connected PV home systems (26%) or grid connected communal grids (10%). - Highlights: • A survey on sources of electricity in Kendu Bay area of Kenya is carried out. • Survey results are used to determine choices and sources of household electricity. • Factors affecting electrification are highlighted. • Survey data are used to build a transition probability matrix (TPM). • The TPM and data from the survey are used to model temporal PV diffusion.

    Hundreds of millions of people in Sub-Saharan Africa do not have access to electricity and will not receive it from national grids in the next few decades. Electricity makes up an important component of rural development and so increasing access can have positive socioeconomic benefits. In this study, we use contingent behavior analysis to quantify the potential benefits of electricity in rural Rwandan villages which currently do not have electricity. The proposed method allows for calculation of net benefits as well as electricity bills. We find that even relatively poor, isolated households would pay for electricity, though amounts vary across households and this affects the financial viability of electrification. Common uses for electricity include lighting, battery charging, and agricultural processing. Despite heterogeneity, opportunities exist to improve rural economic welfare through increased electricity access. - Highlights: • A lack of electricity slows economic growth in rural villages of Sub-Saharan Africa. • Household survey provides data on potential electricity use in Rwandan villages. • Contingent behavior analysis estimates total economic surplus from electricity. • Household electricity bills estimated to calculate investment returns. • Investment in rural electrification likely to bring positive benefits to rural Rwanda.

    The utilization of solar energy, inexhaustible on the earthly scale of time, as heat and light source, today is one of the energetics alternatives more to confront the challenges of the new millennium. Remarkable is the impulse that power generation photovoltaic has received in Brazil. In Pernambuco, state of Brazil, the CELPE - Electric Power Company of Pernambuco, already implanted more than 750 photovoltaic solar home system (95 kW installed) for power supply to rural communities far from the grid connection that come across in commercial operation since 1994. Eight configurations were studied with modifications in their components (panel, battery and charge) with the objective to evaluate the performance and the adequacy of the size these configurations. The parameters utilized for this evaluation were: solar energy diary incident on the panel plat, diary efficiency generator, output voltage on the generator and state of charge the batteries bank. A system of data acquisition automated was fined to measure in real conditions the function of each components, the following parameters: solar radiation incident and temperature on the photovoltaic generator, voltage and generator current, batteries bank and charge and ambient temperature. About the configurations studied, it follows that analysis the operational of characteristics capacity and battery capacity of the SHS utilized, simulating the rural electrification conditions. It was possible to certify the adequate configurations for the load profile will be supply. (author)

    In the programme of total electrification, centralized supply of power generated by conventional methods using exhaustible resources is proving to be uneconomic and, more importantly, unmanageable so far as supply to rural areas, particularly remote places, are concerned. On the other hand, the decentralized approach based on supply of power produced with renewable energy resources available locally is, for various reasons, gradually being recognized as a viable alternative for such remote places. The present paper attempts to examine, from a broad-based socio-economic and environmental point of view, the feasibility of decentralized solar photovoltaic (SPV) system as a source of power compared to that from conventional sources in a remotely located island. The study, based on a sample survey, conducted in an island called 'Sagar Dweep' in West Bengal, India, shows that within a short spell of time of four years, there have been noticeable improvements and significant impact on education, trade and commerce, entertainment, health etc. as a result of supply of power from SPV power plants. Productivity level of some agricultural activities as well as women's participation in different economic activities (at night) other than household work have shown definite signs of betterment. The SPV system is also superior to other conventional systems on consideration of its environmental effects. Thus, on the whole, there seems to be a strong case for the locally installed SPV system in spite of its current unfavourable position in respect of the direct cost of production. (Author)

    2009-01-01

    This article tries to quantitatively capture the effect of political intervention on the operational performance of the Bangladesh Rural Electrification Program (REP). Firstly, efficiency changes over the last 15 years of rural electric cooperatives in the REP are examined using data envelopment analysis (DEA). Then, the critical determinants of the efficiency changes including political indicator are identified with an application of the Tobit model. Results from the DEA analysis show the overall efficiency score, on a scale of zero to one, changes in the 0.856-0.929 range in 15 years, with two turnaround points in 1996 and 2001. These are the years that the national elections were held. The results also find a gap between the efficient rural electric cooperatives and the inefficient rural electric cooperatives. The results of the Tobit model imply that political power has a negative impact on efficiency.

    Low-carbon off-grid electrification for rural areas is becoming increasingly popular in the United Kingdom. However, many developing countries have been electrifying their rural areas in this way for decades. Case study fieldwork in Nepal and findings from United Kingdom based research will be used to examine how developed nations can learn from the experience of developing countries with regard to the institutional environment and delivery approach adopted in renewable energy off-grid rural electrification. A clearer institutional framework and more direct external assistance during project development are advised. External coordinators should also engage the community in a mobilization process a priori to help alleviate internal conflicts of interest that could later impede a project. - Highlights: → Development of community renewable energy projects in the UK is commended. → The UK can benefit from the experience of successful programmes in Nepal. → A clearer institutional framework and more direct external assistance is required. → External coordinators should engage the community in a mobilization process.

    2011-01-01

    This paper presents a case study of the electrification of a riparian community in the State of Para, Brazil, within the scope of the Program for Electric Power Service Universalization in Brazil. The community is located in a remote area; approximately 100 km from the municipal district, there is no regular transport to access the community, and adequate communication service. The community is provided with electrification facilities through a small biomass-based power plant, directly firing residues produced by the local economic activity. The objective of the paper is to propose a sustainable management model that is suitable for community's isolation conditions, considering the high costs with operation and maintenance related to the supply of isolated consumers in small locations. A simulation is conducted for the operation of the small biomass-based power plant, the generation costs are determined, the legal aspects are analyzed, and a suggestion for the management model is presented. - Highlights: → Electrification of isolated consumers is a great challenge for utilities. → Using local labor and resources allows lower energy costs for electrification. → Creation of a specific legislation for utilities is required. → Should also be implemented social activities together with electrification.

    Full Text Available In this paper, we comparatively assess the sustainability of rural electrification efforts based on off-grid solutions in Chile, Ecuador, and Peru. Our assessment considers four dimensions of sustainability (institutional, economic, environmental, and socio-cultural. We found that Ecuador and Chile have consistently failed to ensure mechanisms for the operation and maintenance of the deployed off-grid systems, which has made these solutions in poor Chilean and Ecuadorian communities inevitably unsustainable. Although Peru has adopted a cross-tariff scheme, the Peruvian case shows that ensuring the funding of off-grid PV solutions is not enough. Peruvian officials appear to be unaware of the importance of local participation (local values and lifestyles are constantly disregarded and most of the projects have been designed without the participation and engagement of the communities, which has often led to project failures and payment defaults. However, although each country has its particular challenges, we found that the three Andean countries have consistently neglected the importance of strong formal institutions with a flexible and decentralized structure, which in turn significantly compromised the rural electrification effort in these countries.

  14. Microgrid Utilities for Rural Electrification in East Africa: Challenges and Opportunities

    Science.gov (United States)

    Williams, Nathaniel J.

    Expanding access to electricity is central to development in East Africa but massive increases in investment are required to achieve universal access. Private sector participation in electrification is essential to meeting electricity access targets. Policy makers have acknowledged that grid extension in many remote rural areas is not as cost effective as decentralized alternatives such as microgrids. Microgrid companies have been unable to scale beyond pilot projects due in part to challenges in raising capital for a business model that is perceived to be risky. This thesis aims to identify and quantify the primary sources of investment risk in microgrid utilities and study ways to mitigate these risks to make these businesses more viable. Two modeling tools have been developed to this end. The Stochastic Techno-Economic Microgrid Model (STEMM) models the technical and financial performance of microgrid utilities using uncertain and dynamic inputs to permit explicit modeling of financial risk. This model is applied in an investment risk assessment and case study in Rwanda. Key findings suggest that the most important drivers of risk are fuel prices, foreign exchange rates, demand for electricity, and price elasticity of demand for electricity. The relative importance of these factors is technology dependent with demand uncertainty figuring stronger for solar and high solar penetration hybrid systems and fuel prices driving risk in diesel power and low solar penetration hybrid systems. Considering uncertainty in system sizing presents a tradeoff whereby a decrease in expected equity return decreases downside risk. High solar penetration systems are also found to be more attractive to lenders. The second modeling tool leverages electricity consumption and demographic data from four microgrids in Tanzania to forecast demand for electricity in newly electrified communities. Using statistical learning techniques, improvements in prediction performance was achieved over

    A cost comparison for individual and mini grid photovoltaic systems is made regarding the use of these systems for rural electrification in Northern Brazil. The estimates for maintenance costs were based on existing experience for individual systems already operating in the region. A comparison was also made between modified automotive lead acid batteries commonly used in photovoltaic systems in Brazil and the much more expensive OPzS tubular types. The results of these evaluations show that the maintenance costs are expected to be lower in the case of the mini grids than in individual systems. This is because for a given number of houses to be supplied with electrical energy, they use a smaller number of components subject to failures, like inverters and charge controllers. OPzS batteries are expected to compensate for their higher prices if their predicted operating lifetime can be confirmed under the practical conditions envisaged. (author)

    The electricity authority has, over the years, connected most of population to the electric grid. But for very small villages (2000 villages which are yet to be electrified) and newly established Bedouins settlements (80,000 Bedouin families), the cost of grid connections would be high. The purpose of this paper is to propose planning schemes for off-grid hybrid PV-wind power systems that are suitable for energy requirements and general conditions of Syrian remote small villages. A case study will be introduced where a village with 25 houses and a school is to be supplied by hybrid PV-wind AC systems. The paper presents first a survey and operation evaluation of the PV power systems installed in Syria. Three types of stand-alone PV electrification systems (centralized, individual DC and individual AC systems) with a total capacity of about 100 kW were installed in Syria. Furthermore, the paper presents a summary of the renewable energy development plans, especially PV and PV hybrid systems, included in the renewable energy master plan that was recently performed for Syria. The master plan suggests activities to develop wind, bio-energy, solar, hydro and hybrid systems, which will provide heat and power to Syrian energy needs until 2010. (authors)

    To examine the healthcare utilization and costs of previously uninsured rural children. Four years of claims data from a school-based health insurance program located in the Mississippi Delta. All children who were not Medicaid-eligible or were uninsured, were eligible for limited benefits under the program. The 1987 National Medical Expenditure Survey (NMES) was used to compare utilization of services. The study represents a natural experiment in the provision of insurance benefits to a previously uninsured population. Premiums for the claims cost were set with little or no information on expected use of services. Claims from the insurer were used to form a panel data set. Mixed model logistic and linear regressions were estimated to determine the response to insurance for several categories of health services. The use of services increased over time and approached the level of utilization in the NMES. Conditional medical expenditures also increased over time. Actuarial estimates of claims cost greatly exceeded actual claims cost. The provision of a limited medical, dental, and optical benefit package cost approximately $20-$24 per member per month in claims paid. An important uncertainty in providing health insurance to previously uninsured populations is whether a pent-up demand exists for health services. Evidence of a pent-up demand for medical services was not supported in this study of rural school-age children. States considering partnerships with private insurers to implement the State Children's Health Insurance Program could lower premium costs by assembling basic data on previously uninsured children.

    The universalization of access of the electric energy is one of the goals established by the Brazilian government so as to attend the rural and urban population. The arrival of electric energy in remote and low income areas allows these populations to reach one of the basic conditions to improve the quality of life and citizenship. In order to achieve this goal efficiently, it is necessary to build tools that make possible the impact and process evaluation, searching the continuous improvement of the planning and decision making, either in the direction of the attendance of the proposed goals, or in the poverty mitigation. The knowledge originated from evaluation impact studies provides an important contribution to the improvement of social programs, and a return to society as how the public fund is being managed, promoting transparency and focus. In this context, tolls are developed so as to support the impact and process evaluation in terms of rural electrification publics policies, using a study case that includes about 23.000 questionnaires in 21 states, considering the moment before the access (ex-ante) and after (ex-post), during the years of 2000 and 2004.

    The Banco Nacional de Desenvolvimento Economico e Social - BNDES, a Brazilian bank for the economic and social development - worried about the high connections costs practiced by the energy utilities, made some demands to the Sao Paulo State Government, Brazil to become the agent backer of the rural electrification 'Luz da Terra' program. Two of them was the elaboration and adoption of an unified technical norm privileging the adoption of simplified systems of electric energy distribution and an only system of costs establishment compatible with the goals of low medium connection costs for the state. A model of costs establishment was elaborated through the medium prices of market materials and labor activities whose values were more significant in the final composition of the projects. The model was accepted by the utilities participants of the program as a pattern to establish a reference cost for each project to be executed. The advantage of an unified system is that it allows to each project of grid extension to have its costs of materials and labor activities estimated in the same base, independent of the company involved. In spite of not having been adopted by all the utilities ones, the adoption of an unified system and the establishment of reference costs was essential for the control of rural distribution grids prices in the Sao Paulo State.

    2015-01-01

    Full Text Available The dynamics of solar photovoltaic (PV technology dissemination and utilization has taken center stage in recent years on a global scale, aiming to partly address prevailing rampant energy poverty situations particularly in developing countries. This paper evaluates a flagship electrification project called Ghana Energy Development and Access Project (GEDAP. We purposively sampled 250 solar users in 65 villages across 6 districts in the Upper West region which has the country’s lowest level of electricity access and possibly the highest proportion of abject poverty among its inhabitants compared to the rest of the country. Based on the survey, it can be said that the overall impact assessment of the GEDAP-sponsored off-grid solar PV systems on the quality of life of the local beneficiaries was found to be positively marginal. Among all livelihood assets considered, social capital was markedly enhanced by the provision of modern energy services via isolated solar PV systems. Bottlenecks were identified, including limited system wattage capacity, slight dysfunction of some balance of components, higher interest rates, low technical know-how and inadequate monitoring, all of which are negatively affecting the sustainability of the project. Our findings also indicate that satisfaction derived from solar PV electricity supply among local solar customers differed for varied reasons as follows: moderately satisfied (43%, satisfied (52%, and dissatisfied (5%. For a decisive enhancement of rural livelihoods, we strongly recommend up-scaling system wattage capacity and coverage to build up new or improve upon existing livelihood assets through diversification of the income sources of the local inhabitants.

    Electricity generation in rural communities is an acute problem militating against socioeconomic well-being of the populace in these communities in developing countries, including Nigeria. In this paper, assessments of wind-energy potential in selected sites from three major geopolitical zones of Nigeria were investigated. For this, daily wind-speed data from Katsina in northern, Warri in southwestern and Calabar in southeastern Nigeria were analysed using the Gumbel and the Weibull probability distributions for assessing wind-energy potential as a renewable/sustainable solution for the country's rural-electrification problems. Results showed that the wind-speed models identified Katsina with higher wind-speed class than both Warri and Calabar that were otherwise identified as low wind-speed sites. However, econometrics of electricity power simulation at different hub heights of low wind-speed turbine systems showed that the cost of electric-power generation in the three study sites was converging to affordable cost per kWh of electric energy from the wind resource at each site. These power simulations identified cost/kWh of electricity generation at Kaduna as €0.0507, at Warri as €0.0774, and at Calabar as €0.0819. These bare positive implications on renewable/sustainable rural electrification in the study sites even as requisite options for promoting utilization of this viable wind-resource energy in the remote communities in the environs of the study sites were suggested.

    The project ''Renewable Energy Sustainable Programs for Intelligent Rural Electrifrication'' RESIREA has been looking for the creation of conditions that make possible the establishment of Renewable Energy Technologies (RET) markets in targeted provinces to Lao PDR, Cambodia and Vietnam. As a main result of the project, in three different selected provinces (one in each country) have been proposed villages as ''ready to implement''. The ''ready to implement'' villages are specific RET projects resulted from applying developed methodologies. One methodology is a deeply well structured cross-analysis of technical and economic parameters and the results have been integrated in a Geographical Information System GIS. Based on the least-cost methodology, off-grid biomass and photovoltaic PV power supply systems have been designed and asset for the proposed villages. In the case of PV system designs, a detailed study has been carried out by means of simulations tools and extensive field data. The PV system design looks to contribute to an ''easy scale-up'' concept for off-grid power supply systems, especially when rural communities are too diverse. Further expected benefits besides the supply of electricity services are the improvement of the living and health conditions of the populations, the stimulation of local markets for RET and economic activities.

    2017-06-01

    This paper focuses on the integration of three renewable resources: biogas, wind energy and solar energy, utilizing solar PV panels, a biogas generator, and a wind turbine, respectively, to analyze the technical and economic challenges of a hybrid micro-gird. The integration of these sources has been analyzed and optimized based on realistic data for a real location. Different combinations of these sources have been analyzed to find out the optimized combination based on the efficiency and the minimum cost of electricity (COE). Wind and solar energy are considered as the primary sources of power generation during off-peak hours, and any excess power is used to charge a battery bank. During peak hours, biogas generators produce power to support the additional demand. A business strategy to implement the integrated optimized system in rural areas is discussed.

    Electrification of remote sites in developing countries is often realised trough diesel generator sets and an electric distribution network. This was also the technology used in the village Urambo, where the first rural electrification co-operative in Tanzania was started in 1994. Climate change however calls for decreased fossil fuel combustion worldwide and new technologies have been further developed since the erection of the diesel generator sets in Urambo. It is therefore not obvious that electrification of other rural areas shall follow the Urambo example. In this article, the situation for 250 electricity consumers in Urambo will be demonstrated and the implications for them of introducing new technologies will be evaluated. Technology options regarded in the study are individual photovoltaic (PV) power systems and either incandescent lamps, tube lights or compact fluorescent lights (CFLs) supplied by diesel generation. The different options have been evaluated with respect to consumer costs and environmental impact. The results of the comparison show that PV generation is able to compete with diesel generation if combined with incandescent lamps, but not when tube lights or CFLs are used in the conventional supply system. It should be noted, however, that while the diesel option offer financially more attractive solutions, individual PV systems do not result in any CO 2 emissions. Furthermore, PV systems normally have a higher reliability. However, since the diesel option is not only cheaper but also offers a wider range of energy services and facilitates, future connection to the national electric grid, the conclusion is that this is preferable before individual PV systems for communities similar to Urambo, if the consumers shall pay the full cost of the service

    Senegal is one of the less developed countries in the world (position 158 in a list of 174 countries). 85% of its rural population does not have access to electricity and there's no doubt that this is an important barrier for socio-economic development. In this context, the project Microgrids aims at contributing to solve this problem. This project is part of the Intelligent Energy - Europe Programme supported by the European Commission. Its objective is the promotion and dissemination of the use of micro-grids with high content of Renewable Energy Sources (RES) for the electrification of villages far away from the grid in Senegal. One of the results of the project was the analysis of rural electrification needs, which is described in another paper [Camblong H, Sarr J, Niang AT, Curea O, Alzola JA, Sylla EH, Santos M. Microgrids project, part 1: analysis of rural electrification with high content of renewable energy sources in Senegal. Renewable Energy, submitted for publication.]. This paper presents the design of an electrification kit based on the information provided by that analysis [Analyse des besoins locaux pour l'electrification de zones rurales au Senegal. Technical report of Microgrids project; 2007. Available from: http://www.microgrids-eie.com.]. After identifying necessary previous conditions for the sustainability of any electrification project, a methodology is proposed for the design of the electrification kit. This methodology is applied to a typical village and results are extended to differently sized villages in the areas of Thies, Fatick and Kaolack. Economic considerations are also included to establish the relationship between electrification costs and paying capability of the communities. Now the Microgrids' consortium hopes to set-up a new project to apply the designed kit on some rural non-electrified villages. (author)

  2. A Novel Off-Grid Optimal Hybrid Energy System for Rural Electrification of Tanzania Using a Closed Loop Cooled Solar System

    Full Text Available A large proportion of the world’s populations live in developing countries. Rural areas in many of these countries are isolated geographically from grid connections and they have a very low rate of electrification. The uninterrupted power supply (UPS in these regions is a considerable challenge. The use of renewable energy resources (RER in an off-grid hybrid energy system can be a pathway to solving this problem. Tanzania has a very low electrification rate (rural 16.9%, urban 65.3%. This paper discussed, described, designed a novel uninterruptible, and environmental friendly solar-wind hybrid energy system (HES for remote area of Tanzania having closed loop cooled-solar system (CLC-SS. An optimized configuration for the proposed HES was obtained by Hybrid Optimization Model for Electric Renewable (HOMER analysis software using local solar and wind resources. The designed CLC-SS improved the efficiency of the hybrid solar-wind systems by extracting more power from the solar modules. An evaluation of CLC-SS revealed a 10.23% increase in power output from conventional solar PV modules. The results validate that the optimized system’s energy cost (COE is 0.26 $/kWh and the net present cost (NPC of the system is $7110.53. The enhanced output solar wind hybrid system, designed in this paper is cost-effective and can be applied easily to other regions of the world with similar climate conditions.

  3. Application of jatropha oil and biogas in a dual fuel engine for rural electrification

    2008-06-15

    In this thesis, the technical feasibility of using jatropha oil and biogas for dual fuel generators is investigated. This technology could be used for electricity generation in rural areas in developing countries. The use of jatropha oil and biogas is considered a sustainable energy supply, when both fuels are produced locally. The local production of fuel and generation of electricity could result in economic development and poverty reduction. In order to investigate the technical feasibility, a parameter study is performed, an experimental set-up is constructed and experiments are carried out. Three performance parameters are investigated: thermal efficiency, because it is a direct measure for fuel efficiency; volumetric efficiency, because it is a measure for power output; and air-excess ratio, because it influences particulate emissions and HC emissions. The parameter study is conducted, to predict the effect of dual fuel operation, by deriving expressions for the performance parameters. The experiments are carried out to assess the effect of dual fuel operation on performance and to find the operation limits (smoke limit and knock limit). Experiments are carried out on a 12 kW diesel generator set. The jatropha oil that is used is pure oil. Biogas mainly consists of methane and carbon dioxide. Simulated, bottled, biogas of different quality is used (i.e. CH4/CO2 ratios). Pure methane is also tested as gaseous fuel. Gas is added to the inlet air with a venturi. The design of the venturi limited the gas flow; consequently the maximum heat release fraction of methane was 80% for pure methane and approximately 70% for biogas. Tests were performed at 6, 8 and 10 kW load. The engine showed a thermal efficiency characteristic for pure jatropha oil operation, which is expected for a diesel generator. The characteristic for jatropha oil did not deviate from that of diesel. At full load, thermal efficiency is approximately 32%. Under dual fuel operation, with biogas, at

    This thesis has for object the evolution of the economic optimum in the electric industry under spatial equity constraint that present a strong spatial heterogeneity of its supply conditions. One analyses the evolution of the rural electrification regime in France both in terms of economic and social efficiency. We examine the rationality of extending the sectoral optimization under equity constraint to the rationalization of electricity end-uses in the heterogeneous space of rural electricity supply. To this question are given two responses. The firsts pertains to modify the incentives in the institutional regime of rural electrification so the MDE may be integrated in the strategies of rural electrification syndicates. One inspire from incentives mechanisms of the anglo-saxon DSM practice. The second is statistical zoning method of demand and distribution grid whose object is to localize action basins for large scale MDE projects. (author)

    Highlights: • Estimation of the output temperature reached by 2 m parabolic dish. • Output power estimation for uncontrollable load was done using Matlab®. • Validation of the proposed system under Tunisian conditions for rural electrification. - Abstract: The development of green power generation such as solar systems that have become a great interest for several countries especially for Tunisia as it presents a significant solar potential. For this purpose, this research has investigated the feasibility and the performance of standalone solar dish/Stirling micro generation plant for rural electrification. The considered hybrid system includes solar dish/Stirling engine, permanent magnet synchronous generator and a storage battery. To start with, thermal modeling and simulation have been carried out using Matlab® for the solar-driven Stirling heat engine system composed of an Alpha Stirling engine, a solar collector and a receiver, in which the radiation, convection, conduction and radiation heat loss have been taken into consideration for the selected design. For numerical validation of the receiver’s thermal model, simulation results were compared with experimental measurements reported for the EURODISH system with a reasonable degree of agreement. Second, the generated torque driving the generator has been estimated by the Adiabatic model of URIELI based on the classical fourth-order Runge-Kutta. In order for an autonomous control, the dish generator is connected to the load via power electronic converters where the bidirectional power flow is possible by the use of two voltage source converters in a back-to-back configuration. They are referred to as Stirling/generator side converter and load side inverter, both are oriented control by space vector pulse width modulation. In this context, the Stirling side converter is used to adjust the synchronous generator while the inverter controls the power flow between the direct current bus and the

    Electrification programmes and projects are usually planned and evaluated on the basis of their economic (financial) and socio-economic performance. It is not usually recognised that electrification is often carried out for social objectives of poverty alleviation and political effect. Examination of electrification in South Africa reveals clearly that initial electrification was to meet economic objectives, later socio-economic objectives were adopted, and recently the objectives were social. Social electrification, particularly rural electrification, is not viable according to usual assessment methods, which are frequently distorted to provide the justification for a project to proceed. The technology of network electrification changed to meet the constraints, challenging usual perceptions about the relative costs of urban and rural electrification and the potential for photovoltaic electrification. Adopting a specification for social electrification allows suitable tariffs for electrification to be identified, indicates how capital investment decisions might be modified for social electrification, and identifies implications for electricity industry restructuring. A better understanding of electrification's social objectives has implications for projects and programmes in other developing countries

    While the United States quickly had the largest electrical indus in the world, electrification in rural areas ended about thirty years after most European countries. Public intervention is a deciding factor in completing electrification, and the late involvement by the American authorities explains the gap. However it would be wrong to oppose in Europe and in the United States a motivated public sector and little involved private companies. In both continents indeed, major private and public urban distributors were almost not involved in rural electrification processes, where local players prevailed: local communities around Europe, small and medium size business in some European countries such as France, co-operative companies in the United States. Additionally, there is an essential difference between electrification in Europe and in the United States. The former does not provide much more than lighting and its success leaves few traces in popular memories; the latter includes many facilities and services, changes the lives of rural populations and is celebrated a such. Whereas the colonial venture keep European economies away from their domestic markets, while in the United States the urban market growth contents large companies, the American co-operative movement is right to believe in the existence of a large electrical equipment market among farmers then considered poor and behind. It even uses the market to complete a more profitable and less costly electrification. Electricity stories that offer food for the thoughts of Third World decision makers and power companies, when they entrust most rural electrification to their large urban companies and deny the existence of a real equipment market in their own rural world.

    Cooperativa Regional de Eletrificacao Rural do Alto Uruguai LTDA - CRERAL was created in July 23rd, 1969, to take energy to the countryside, because the concessionaire did not use to do that in that time. CRERAL has been distributing electric energy in the countryside for 33 years and, recently, it has been producing energy too. This work shows a brief historic of CRERAL and a new scenario to the cooperatives of rural electrification in relation to the new Brazilian electric model. After 33 years, CRERAL has a great experience in distributing electric energy in the countryside. In 2001, CRERAL had 5,647 partners using the energy in 37 cities in the north region of Rio Grande do Sul, with its head-office in Erechim - RS, with an electric system of 1,781 km of web and 18,890 posts, 1,475 transformers installed with a potency of 17,161 KVA. CRERAL has implanted a model of democratic management, that permits the partners to take part in the decisions of the cooperative, including organized groups in the communities (that are 105 today) and the general assembly. The partners define the priorities, the changes, the investments and the tariff to be charged. With studies starting in 1997, CRERAL started producing energy. In 2000, was inaugurated the first PCH. With a potency of 720 KW, Abauna Dam was responsible for 26% of the energy consumed by the cooperative in 2001. Cascata das Andorinhas PCH Dam, with a potency of 1,000 KW , is being built and it must be working by the end of 2002. The new electric model will bring great changes to the cooperativism of electrification with the possibility that the cooperatives be transformed in permissionaires of public service of energy, but it will also represent a great challenge to be inserted and to continuo existing in this new scenario.

    2007-01-01

    Market-based rural electrification with solar energy is increasingly common in developing countries. This article revolves around three main claims about solar electrification in Kenya's unsubsidized market: (1) The benefits of solar electrification are captured primarily by the rural middle class. (2) Solar electricity plays a modest role in supporting economically productive and education-related activities, but 'connective' applications such as television, radio, and cellular telephone charging often receive a higher priority. (3) Solar electrification is more closely tied to increased television use, the expansion of markets, more rural-urban communication, and other processes that increase rural-urban connectivity than to poverty alleviation, sustainable development, or the appropriate technology movement.

    People in industrialized countries enjoy nowadays the luxurious advantages of energy. Electricity has converted the former preindustrial economies and societies into highly industrialized, mechanized and automated ones. On the contrary, many rural areas in developing countries are suffering from the heavy lack of access to energy, such as Bangladesh. Grameen Shakti, a subsidiary of the world famous Grameen family set up by Nobel Laureate Muhammad Yunus, has created a market for renewable energy technologies in Bangladesh, though not in the industrial and commercial areas but in the very poor and energy-starved rural areas of the country. By employing a special market-based business model, Grameen Shakti provides rural households with access to renewable energy technologies and thus with electricity. The objective of this study is the analysis and depiction of the functionality of this business model, its structural aspects, implications as well as replication potential. (orig.)

    Full Text Available En el presente trabajo se desarrolla un modelo para la valoración integral de distintas tecnología de electrificación rural, basado fundamentalmente en el comportamiento de los sistemas híbridos que emplean fuentes renovables de energía, considerando múltiples criterios, tales como: el porcentaje de generación diesel requerido, costo de la energía equivalente, valor presente neto, costo de operación y mantenimiento, riesgos de la instalación y facilidad de gestión del sistema. Se estudian ocho sistemas energéticos, dimensionados para ofrecer una calidad similar a la extensión de red, que pueden satisfacer distintos escenarios de recursos energéticos y consumos de energía desde 20 hasta 320 kWh/día, y se emplea el modelo matemático desarrollado en un caso práctico, a través del cual se demuestra la facilidad que presenta para valorar tecnologías de electrificación rural, ameritando solo tres datos característicos de la comunidad: la irradiación solar promedio, la velocidad de vientos y el consumo de energía estimada.In this work it is developed a model for the integral valuation of different technology of rural electrification, the study of the behavior of the hybrid systems was emphasized with the use of renewable energy sources and it was considered multiple approaches for the valuation, such as: the percentage of required generation diesel, cost of the equivalent energy, net present value, operation cost and maintenance, risks of the installation and easiness of administration of the system. A group of eight sized energy systems was studied to offer a similar quality to the one given by the net extension net, with which it can satisfy energy consumptions from 20 up to 320 kWh/day, estimating the behavior of the proposed systems for different scenarios of energy resources readiness. The developed mathematical pattern allows valuing technologies for rural electrification using three characteristic data of the community

  20. Expanding access to off-grid rural electrification in Africa: An analysis of community-based micro-grids in Kenya

    Kirubi, Charles Gathu

    Community micro-grids have played a central role in increasing access to off-grid rural electrification (RE) in many regions of the developing world, notably South Asia. However, the promise of community micro-grids in sub-Sahara Africa remains largely unexplored. My study explores the potential and limits of community micro-grids as options for increasing access to off-grid RE in sub-Sahara Africa. Contextualized in five community micro-grids in rural Kenya, my study is framed through theories of collective action and combines qualitative and quantitative methods, including household surveys, electronic data logging and regression analysis. The main contribution of my research is demonstrating the circumstances under which community micro-grids can contribute to rural development and the conditions under which individuals are likely to initiate and participate in such projects collectively. With regard to rural development, I demonstrate that access to electricity enables the use of electric equipment and tools by small and micro-enterprises, resulting in significant improvement in productivity per worker (100--200% depending on the task at hand) and a corresponding growth in income levels in the order of 20--70%, depending on the product made. Access to electricity simultaneously enables and improves delivery of social and business services from a wide range of village-level infrastructure (e.g. schools, markets, water pumps) while improving the productivity of agricultural activities. Moreover, when local electricity users have an ability to charge and enforce cost-reflective tariffs and electricity consumption is closely linked to productive uses that generate incomes, cost recovery is feasible. By their nature---a new technology delivering highly valued services by the elites and other members, limited local experience and expertise, high capital costs---community micro-grids are good candidates for elite-domination. Even so, elite control does not necessarily

    Although development organizations agree that reliable access to energy and energy services—one of the 17 Sustainable Development Goals—is likely to have profound and perhaps disproportionate impacts on women, few studies have directly empirically estimated the impact of energy access on women’s empowerment. This is a result of both a relative dearth of energy access evaluations in general and a lack of clarity on how to quantify gender impacts of development projects. Here we present an evaluation of the impacts of the Solar Market Garden—a distributed photovoltaic irrigation project—on the level and structure of women’s empowerment in Benin, West Africa. We use a quasi-experimental design (matched-pair villages) to estimate changes in empowerment for project beneficiaries after one year of Solar Market Garden production relative to non-beneficiaries in both treatment and comparison villages (n = 771). To create an empowerment metric, we constructed a set of general questions based on existing theories of empowerment, and then used latent variable analysis to understand the underlying structure of empowerment locally. We repeated this analysis at follow-up to understand whether the structure of empowerment had changed over time, and then measured changes in both the levels and likelihood of empowerment over time. We show that the Solar Market Garden significantly positively impacted women’s empowerment, particularly through the domain of economic independence. In addition to providing rigorous evidence for the impact of a rural renewable energy project on women’s empowerment, our work lays out a methodology that can be used in the future to benchmark the gender impacts of energy projects.

    The maximization of the efficiency in the electric energy conversion is essential to the developing of technical and economic viability of photovoltaic solar energy systems. This paper presents the development of an electronic converter with maximum power point tracking for photovoltaic systems applied to rural electrification. The standalone photovoltaic system used is similar to the systems installed by Companhia Energetica de Minas Gerais - CEMIG in the schools of isolated communities, inside the Solar Light Program. Initially were developed test procedures of the equipment used in the system like photovoltaic generators, electronic ballasts, inverters, charge controllers and batteries, covering minimum performance requirements and in compliance with national and international standards, as possible, due to the instrumentation availability. A data acquisition system was assembled to monitoring the photovoltaic system. A simulation of the system was implemented and the aims were to optimize the project and carry out a comparative study with the monitoring results. The converter with maximum power point tracking consists of a direct current converter in the buck configuration and the control algorithm was implemented in a micro controller, being the first results presented here. After finished the prototype, it will be incorporated in the photovoltaic system and will be accomplished a study of the technical and economic viability. The first results of the tests, of the monitoring and of the converter with maximum power point tracking are helping the sustainability of the systems installed by CEMIG, funding the government initiatives in the quality control of equipment and promoting the development of national technology.

    The publication earlier this year of the joint BR-DTp final report of the review of main line electrification represented the culmination of over two years work; the study is almost certainly the most complex and comprehensive of this type ever undertaken. Heavy reliance on computer models allowed business analysis over the 34-year timespan of the review to extend to a level of detail that was not expected at the time of the last such investigation, the 1931 Weir Report of the Committee on Main Line Railway Electrification. It is encouraging that, despite the sweeping changes in both technology and economic conditions during the intervening years, the verdict remains highly favourable.

  6. Connective power: Solar electrification and social change in Kenya

    Science.gov (United States)

    Jacobson, Arne Edward

    Household solar photovoltaic systems have emerged as a key alternative to grid-based rural electrification in many developing countries. This may seem a victory for appropriate technology advocates, but my research indicates that the social significance of solar electrification in Kenya, which is among the largest developing country solar markets per capita, is far removed from the classic "small is beautiful" neo-populist vision of building small-scale alternatives to global capitalism. Instead, solar electrification is more closely connected to neo-liberal goals of market-based service provision and economic integration. In this study I combine quantitative and qualitative methods, including surveys, intra-household energy allocation studies, and historical analysis, to analyze the social significance of solar electrification in Kenya. I find that "connective" applications, including television, radio, and cellphones, are centrally important. Television is especially notable; the expansion of TV broadcasting to rural areas was a key condition for solar market development. Solar electricity is also used for lighting. In Kenya, income and work related uses of solar lighting are modest, while education uses are more significant. However, in many households, especially those with small systems, intra-household dynamics constrain key social uses (e.g. children's studying), as the energy is allocated to other uses. Social use patterns combine with access dynamics in Kenya's unsubsidized market to shape the social significance of solar electrification. Solar ownership is dominated by the rural upper and middle classes. Thus, productivity and education uses make small contributions to differentiation and middle class formation. Additionally, solar electrification's role in supporting rural television and radio use improves business advertisers' ability to expand consumer goods markets. These findings link solar electrification to important processes of rural development

    This publication describes the development of electrified propulsion systems from the invention of the automobile to the present and then provides an outlook on expected technology progress. Vehicle application areas for the various systems are identified based on a range of energy supply chains and the technological limits of electric powertrain components. GM anticipates that vehicle electrification will increase in the future. Battery-electric vehicles will become competitive for some applications, especially intra-urban, short-distance driving. Range-extended electric vehicles provide longer driving range and offer full capability; with this technology, electric vehicles can serve as the prime vehicle for many customers. Hydrogen-powered fuel cell-electric powertrains have potential for application across most of the vehicle segments. They produce zero emissions during all phases of operation, offer short refueling times, but have powertrain cooling and hydrogen storage packaging constraints. While the market share of electrified vehicles is expected to increase significantly, GM expects conventional powertrains with internal combustion engines to also have a long future - however, a lot of them will be supported by various levels of electrification.

    The Interstate Electrification Improvement Project, publicly known as the Shorepower Truck Electrification Project (STEP), started in May 2011 and ended in March 2015. The project grant was awarded by the Department of Energy’s Vehicles Technology Office in the amount of $22.2 million. It had three overarching missions: 1. Reduce the idling of Class 8 tractors when parked at truck stops, to reduce diesel fuel consumption and thus U.S. dependence on foreign petroleum; 2. Stimulate job creation and economic activity as part of the American Reinvestment and Recovery Act of 2009; 3. Reduce greenhouse gas emissions (GHG) from diesel combustion and the carbon footprint of the truck transportation industry. The project design was straightforward. First, build fifty Truck Stop Electrification (TSE) facilities in truck stop parking lots across the country so trucks could plug-in to 110V, 220V, or 480VAC, and shut down the engine instead of idling. These facilities were strategically located at fifty truck stops along major U.S. Interstates with heavy truck traffic. Approximately 1,350 connection points were installed, including 150 high-voltage electric standby Transport Refrigeration Unit (eTRU) plugs--eTRUs are capable of plugging in to shore power1 to cool the refrigerated trailer for loads such as produce, meats and ice cream. Second, the project provided financial incentives on idle reduction equipment to 5,000 trucks in the form of rebates, to install equipment compatible with shore power. This equipment enables drivers to shut down the main engine when parked, to heat or cool their cab, charge batteries, or use other household appliances without idling—a common practice that uses approximately 1 gallon of diesel per hour. The rebate recipients were intended to be the first fleets to plug into Shorepower to save diesel fuel and ensure there is significant population of shore power capable trucks. This two part project was designed to complement each other by

    About 72 million households in rural India do not have access to electricity and rely primarily on traditional biofuels. This research investigates how rural electrification could be achieved in India using different energy sources and what the effects for climate change mitigation could be. We use the Regional Energy Model (REM) to develop scenarios for rural electrification for the period 2005-2030 and to assess the effects on greenhouse gas emissions, primary energy use and costs. We compare the business-as-usual scenario (BAU) with different electrification scenarios based on electricity from renewable energy, diesel and the grid. Our results indicate that diesel systems tend to have the highest CO 2 emissions, followed by grid systems. Rural electrification with primarily renewable energy-based end-uses could save up to 99% of total CO 2 emissions and 35% of primary energy use in 2030 compared to BAU. Our research indicates that electrification with decentralised diesel systems is likely to be the most expensive option. Rural electrification with renewable energy tends to be the most cost-effective option when end-uses are predominantly based on renewable energy, but turns out to be more costly than grid extensions when electric end-use devices are predominantly used. This research therefore elaborates whether renewable energy is a viable option for rural electrification and climate change mitigation in rural India and gives policy recommendations.

    option considering its social and political impact, but does not always provide a sufficient service quality. Grid extensions require substantial investments in heavy infrastructures, which cannot be profitable in remote areas where population density remains low. Besides, the UN progressively highlights the fact that in places where grid connections do exist, the beneficiaries are exposed to regular blackouts. The example of China's grid extension policy implemented over its whole territory confirms that this solutions is not always adapted. Nevertheless, innovative and promising projects are flourishing in areas hardly reachable by grid extension policies. To this respect, Bangladesh has achieved remarkable results in decentralized rural electrification. Over the last decade, renewable decentralized electricity production systems developed, breaking technological barriers that have made these systems expensive, complex and unreliable for years. They benefited from a 75% drop in the price of photovoltaic panels since 2009 and a 42% drop in the price of batteries since 2008. The emergence of these systems shows the increasing interest given to a new idea of what electrification might be, based on the concept of 'energy ladder', in which the first step equals a minimum consumption level allowing the use of a few light bulbs. If this approach does not give access to the same level of electricity consumption per year than the one theoretically provided by the grid, at least it gives the opportunity for people in need to access rapidly a basic lighting service, more efficient than traditional solutions. Poorly deployed at the moment, off-grid and mini-grid systems are increasingly raising support in a context of deep rethinking of our energy systems, pushing governments to consider innovative and sustainable solutions to face the challenges of poverty and climate change. Numerous obstacles still need to be overcome though, in order to create the conditions for a stable

    NONE

    2000-10-01

    This report is a contribution to a growing body of work which acknowledges the importance of social considerations in the electricity industry, and provides an electricity industry perspective on the role of social trust, which is closely related to concepts such as social responsibility, corporate governance and corporate stewardship. The report provides a full explanation of the concept of social trust, defines its components (competence, commitment, consistency, fairness, respect, caring and empathy) and makes suggestions as to how each of these components could be implemented in a variety of settings and situations such as facility planning, construction and operation, risk management and customer relations.

    There is a basic historical contradiction in France being the leader in public electrification while at the same time the French state has never assumed the associated financial or business risks. The electrification of the country has been built virtually entirely around decentralized initiatives and the national company has only completed, modernized and managed the existing system though doubtless with a great deal of professionalism and success. It is probably this very professionalism and success which have given electrical producers an the Third World, (seeking a role model in the developed world), a false image of the future of this sector, presenting it as that of a large company moving from the centre outwards, from the town to the rural world. Beyond the ideologies of public versus private which have left their mark on the history of electricity for several decades, the French experience gives the image of an electrification programme which is being built up by the will of the people, where a centralized and highly legislative State has succeeded in both stimulating a large number of private entrepreneurs, large and small alike, and mobilizing tens of thousands of districts sharing this ambition, as shown by the example of Labastide Murat, a small village in the South West of France.

    The experience of Kiribati in PV-based rural electrification is unusual and important, as Kiribati originally failed in its attempt to use PV for rural electrification through purchase of systems by rural households. Kiribati then changed the institutional structure of the solar implementation agency to a service-based institution and turned failure into success. The energy service concept developed by the Solar Energy Company has assured reliable operation of solar home systems during the past ten years. A currently ongoing project, funded by the European Union, is dealing with the extension of this concept to increase the solar home systems from the existing 300 to 2100, bringing the coverage of the electrified rural households to 20%

    In Third World countries, the vast majority of the rural population does not have access to electricity. The factors that affect rural electrification policies include economic, demographic, social, and cultural factors and the fact that each country has its own policy regarding electrification. Since 1963, Morocco has been aware that rural electrification represents an important aspect of sustainable development. The government of Morocco has implemented several initiatives to overcome the challenge of rural electrification. This paper presents a brief historical overview of key dates in the rural electrification in Morocco. In particular, the authors discussed Morocco's Global Rural Electrification Program (PERG), outlining its global approach, master plan, and implementation. To finance this endeavour, Morocco relies on several international institutions ready to help in accordance with the priorities determined by the State. For example, funds have been provided by the Agence Francaise de Developpement (AFD), Japan Bank for International Cooperation (JBIC), Islamic Development Bank (IDB), the KFW and the FADES. The socio-economic impact of rural electrification was also reviewed, noting increased economic activity and a 30 per cent reduction in emigration from electrified villages. Households also benefit from improved hygiene and quality of life. 1 tab.

    A decentralized power generation plant fuelled by straight jatropha oil was implemented in 2006 in Ranidhera, Chhattisgarh, India. The goal of this study was to assess the environmental sustainability of that electrification project in order to provide a scientific basis for policy decisions on electrifying remote villages. A full Life Cycle Assessment (LCA) was conducted on jatropha-based rural electrification and then compared with other electrification approaches such as photovoltaic (PV), grid connection and a diesel-fuelled power generator. In summary, the jatropha-based electrification in Ranidhera reduces greenhouse gas emissions over the full life cycle by a factor of 7 compared to a diesel generator or grid connection. The environmental performance is only slightly improved, mainly due to the high air pollution from pre-heating the jatropha seeds. With additional measures oil extraction and overall efficiency could be further improved. However, environmental benefits can only be achieved if jatropha is cultivated on marginal land and land use competition can be excluded. Under these conditions, jatropha-based electricity generation might be a useful alternative to other renewable electrification options, as the technology is very sturdy and can be maintained even in remote and highly under-developed regions.

    Volcanic lightning detection has become a useful resource for monitoring remote, under-instrumented volcanoes. Previous studies have shown that the behavior of volcanic plume electrification responds to changes in the eruptive processes and products. However, there has not yet been a study to quantify the links between ash textures and plume electrification during an actively monitored eruption. In this study, we examine a sequence of vulcanian eruptions from Sakurajima Volcano in Japan to compare ash textural properties (grain size, shape, componentry, and groundmass crystallinity) to plume electrification using a lightning mapping array and other monitoring data. We show that the presence of the continual radio frequency (CRF) signal is more likely to occur during eruptions that produce large seismic amplitudes (>7 μm) and glass-rich volcanic ash with more equant particle shapes. We show that CRF is generated during energetic, impulsive eruptions, where charge buildup is enhanced by secondary fragmentation (milling) as particles travel out of the conduit and into the gas-thrust region of the plume. We show that the CRF signal is influenced by a different electrification process than later volcanic lightning. By using volcanic CRF and lightning to better understand the eruptive event and its products these key observations will help the monitoring community better utilize volcanic electrification as a method for monitoring and understanding ongoing explosive eruptions.

    In September 2015, the international community has adopted a new set of targets, following and expanding on the millennium development goals (MDGs), the Sustainable Development Goals (SDGs). Ensuring access to affordable, reliable, sustainable and modern energy for all is one of the 17 set goals that each country should work towards realizing. According to the latest Global Tracking Framework, 15% of the global population live without access to electricity. The majority of those (87%) reside in rural areas. Countries can reach universal access through various electrification options, depending on different levels of energy intensity and local characteristics of the studied areas, such as renewable resources availability, spatially differentiated costs of diesel-fuelled electricity generation, distance from power network and major cities, population density and others, data which are usually inadequate in national databases. This general paucity of reliable energy-related information in developing countries calls for the utilization of geospatial data. This paper presents a Geographic Information Systems (GIS) based electrification analysis for all countries that have not yet reached full access to electricity (Sub-Saharan Africa, Developing Asia, Latin America and Middle East). The cost optimal mix of electrification options ranges from grid extensions to mini-grid and stand-alone applications and is identified for all relevant countries. It is illustrated how this mix is influenced by scrolling through various electrification levels and different oil prices. Such an analysis helps direct donors and investors and inform multinational actions with regards to investments related to energy access.

    The present paper is an analysis of the rural electrification usage. Rural production requires efficient energy sources, and the State must encourage landowners to make use of market forces to modernize their activities. Important authors have claimed that rural electrification should be viewed as an investment in the energy structure of a region, an investment to achieve economic returns. In this paper, this opinion is criticized in light for the need of sustainable rural development. More than just a macroeconomic policy, electrification should be viewed through a social lens, as indispensable component of citizenship. (author)

    The lower St. Lawrence region of Quebec is a rural area with little industry and does not possess important hydraulic resources. Electrification of this region progressed slowly and in an uneven manner. From 1888 to 1922, many local distributors, private or municipal, gave a mediocre quality of service to a small number of customers. A regional firm, the Compagnie de Pouvoir du Bas St-Laurent, followed in 1922 but its resources remained limited, and in a few years it passed under the control of American capitalists. The most rural sectors of the region were badly provided with electricity even in 1945, and the state, in the form of the Office de l'Electrification Rurale, had to intervene to remedy this situation. The Office took charge of organizing and financing electric power distribution cooperatives which ensured service in the most remote zones of Quebec. At the beginning of the 1960s, the inequalities in electric power rates in the region supplied a weighty argument to those in favor of nationalization of power companies. The Compagnie de Pouvoir was acquired by Hydro-Quebec in 1963 and the region was finally correctly integrated with the provincial grid. The cooperatives were also acquired by the Crown corporation a short time thereafter. Electrification was not only building power plants and distribution networks, but also involved development of consumption of electricity on farms and in homes. This made city comforts universal and modified rural life styles, for example by the introduction of electric appliances. 430 refs., 35 figs., 70 tabs

    This paper looks at the role of the National Rural Electric Cooperative Association (NRECA) with regard to applying renewable energy in a village setting. This group has historically been active with state utilities to promote extension of the grid system, and until recently has no historical involvement with renewable resources. They have realized that most future clients will not be served by extending the grid, because of the costs involved, and that renewables play a part of the solution to this problem. NRECA has sought to provide project management and management consultant services, emphasizing training, management efficiency, cost of services studies, and assistance in dealing with regulations. They specialize in forming, training, and supporting user-owned electric service companies, and rely on other partners for technological services and support.

  7. A multi-scalar investigation of development and health in Ethiopia: household electrification in a agriculturally dependent and climate sensitive country

    2017-12-01

    In poor countries, household electricity status is often used as a measure of household resources. Often, the primary use of the variable is to sort the poorest households - those without electricity - from the better-off households - those with electricity. Expanding electrification is also part of a suite of goals developed by health and development and reflected in the Millennium Development Goals (MDG) and now the UN's Sustainable Development Goals. Therefore, this measure is also used in a macro-level description of a country to describe a country's process of urbanization or development. As countries, electrify and expand access to electrification to the poorest households and communities, understanding the role and impact of electrification on the health and development of these communities is necessary. In other words, moving beyond the binomial categorization of a household as electrified or not electrified and instead investigating the ways that electrification impacts communities, households and individuals is a necessary component of understanding contemporary patterns of health and development in the world's poorest countries. The goal of this research is to examine the linkages between health and development using multi-scalar, remotely-sensed measures of electrification in Ethiopia, one of the poorest countries in the world. For this study we use spatially referenced Demographic and Health Survey (DHS) data for Ethiopia from 2000 and 2005. In addition to measures of electrification gathered from the DHS, we also use time-varying satellite based measure of electrification collected by the US Department of Defense. Also, because many rural Ethiopians are dependent on small-scale, rainfed agriculture and therefore highly vulnerable to climate shocks and food insecurity, any investigation of health and development must also consider the local food production context. To support the analysis and provide information on broader measures of food insecurity

    The primary objective of this pre-feasibility evaluation is to examine the economic and technical feasibility of replacing distillate fuel with local waste biomass in the village of Verkhni-Ozerski, Arkhangelsk Region, Russia. This village is evaluated as a pilot location representing the off-grid villages in the Russian Northern Territories. The U.S. Department of Energy (DOE) has agreed to provide technical assistance to the Ministry of Fuel and Energy (MFE). MFE has identified the Northern Territories as a priority area requiring NREL`s assistance. The program initially affects about 900 off-grid villages. Biomass and wind energy, and to a lesser extent small hydro (depending on resource availability) are expected to play the dominant role in the program, Geothermal energy may also have a role in the Russian Far East. The Arkhangelsk, Kariela, and Krasnoyarsk Regions, all in the Russian Northern Territories, have abundant forest resources and forest products industries, making them strong candidates for implementation of small-scale waste biomass-to-energy projects. The 900 or so villages included in the renewable energy program span nine administrative regions and autonomous republics. The regional authorities in the Northern Territories proposed these villages to MFE for consideration in the renewable energy program according to the following selection criteria: (a) Remote off-grid location, (b) high cost of transporting fuel, old age of existing power generation equipment, and (d) preliminary determination as to availability of alternative energy resources. Inclusion of indigenous minorities in the program was also heavily emphasized. The prefeasibility study demonstrates that the project merits continuation and a full feasibility analysis. The demonstrated rate of return and net positive cash flow, the willingness of Onegales and local/regional authorities to cooperate, and the immense social benefits are all good reasons to continue the project.

    The worldwide growth of uranium power plant capacity is obviously dependent on both the growth of electrification and the competitive status of uranium power. In this paper the thesis is developed that expanded use of uranium power is essential to provide a substantial portion of the electricity necessary for world economic growth. Further, the case is made that the obstacles to this expansion arise not from the technology, but rather from the inadequacies of our industrial, political, and economic institutions to manage this new energy system effectively, nationally and internationally. Data are presented on the relation between electricity consumption and GNP; percentage of primary energy used for electricity; energy price ratio; relative generation costs of U, coal and oil-fired power plants; generating costs and capacity factors of conventional and uranium power plants.

    is expanding our current understanding and outline the areas of advancement needed in the future. Presentation is made of current models for wind driven detachment/entrainment and the transport rates of sand and dust, including the effects of contact induced grain electrification. This ubiquitous phenomenon...... can affect grain transport through the generation of intense electric fields and processes of electrostatic assembly. Importantly the transport of sand is characterized by saltation, which is known to be an active process for erosion and therefore a source for dust and sand formation. Using novel...... erosion simulation techniques the link between grain transport rates and erosion rates has been quantified. Furthermore this can be linked to production rates for dust and has been associated with chemical and mineral alteration through a process of mechanical activation of fractured surfaces.

    The lower St. Lawrence region of Quebec is a rural area with little industry and does not possess important hydraulic resources. Electrification of this region progressed slowly and in an uneven manner. From 1888 to 1922, many local distributors, private or municipal, gave a mediocre quality of service to a small number of customers. A regional firm, the Compagnie de Pouvoir du Bas St-Laurent, followed in 1922 but its resources remained limited, and in a few years it passed under the control of American capitalists. The most rural sectors of the region were badly provided with electricity even in 1945, and the state, in the form of the Office de l'Electrification Rurale, had to intervene to remedy this situation. The Office took charge of organizing and financing electric power distribution cooperatives which ensured service in the most remote zones of Quebec. At the beginning of the 1960s, the inequalities in electric power rates in the region supplied a weighty argument to those in favor of nationalization of power companies. The Compagnie de Pouvoir was acquired by Hydro-Quebec in 1963 and the region was finally correctly integrated with the provincial grid. The cooperatives were also acquired by the Crown corporation a short time thereafter. Electrification was not only building power plants and distribution networks, but also involved development of consumption of electricity on farms and in homes. This made city comforts universal and modified rural life styles, for example by the introduction of electric appliances. 430 refs., 35 figs., 70 tabs.

    Substantial burden of diabetes and hypertension is on rise in India, leading to a twin epidemic. India, being a rural country, has unique problems regarding the treatment compliance which is a serious risk for morbidity and mortality. To assess the compliance to treatment of hypertension and diabetes amongst the diagnosed patients from rural area and to study reasons of non-compliance and knowledge and attitude. Community based, cross sectional, observational study conducted in the rural communities of Tara and Barapada villages of Raigad district of Maharashtra. Survey was conducted covering population of 2115 across 360 families, 250 at Barapada and 110 at Tara. All the cases of diabetes and hypertension diagnosed for more than one year were included. A structured and pre-tested questionnaire was administered including details on demography, medical documentation, treatment details and factors assessing the compliance, knowledge and attitude towards the diseases. When reviewed the treatment adherence pattern based on documentary evidence and interview of the patient, on history of taking medication strictly since the detection illness, it was found that more than 70% of the Diabetics and more than 75% of the Hypertensive have discontinued the treatment in between. The most common reasons of non-compliance is the lack of sufficient motivation for treatment adherence as many mentioned (61.4% diabetics, 55.8% hypertensives) difficulty to remember to take daily medication due to work or forgetfulness. This is followed by lack of money (50%diabetics, 55.8% hypertensives) and living far away from doctor in city (43% diabetics and 46% hypertensives). The study findings are only tip of iceberg and the non-adherence to the treatment of diabetes and hypertension in rural population is at alarmingly high. Illiteracy, lack of faith in treatment and motivation, unawareness and self-neglect as well as financial constraints and lack of specialist care in rural area is playing

    Full Text Available The increasing electrification of the transport infrastructure, residential and commercial sectors of a “smart city” induces structural changes in energy sector. This investigation will enhance our understanding of mechanisms to develop a regional power industry, which would serve intellectual technologies of future urban environment considering national features. The authors define electrification as the process of bringing the most advanced energy carrier — electricity — to the national economy. This process integrates the spheres of electric power consumption and electric power generation. The article identifies the features and key trends in a new electrification stage in «smart cities». The paper shows that the energy sector of such cities combines centralized and decentralized technological solutions. This requires a certain readjustment of the distribution and sales divisions of the regional electric power industry. In particular, modernization of low-voltage distribution networks, improvement of tariff policy, implementation of programs of energy demand management are needed. The authors reveal priority areas for electrification in smart cities. Firstly, these cities need to develop electric transport, electric cars and associated infrastructure. Secondly, the introduction of various control systems for residential appliances will make households smarter. We show the impact of electric cars on the electricity market and loads in a regional energy system. In particular, we analyse the foreign experience of electric cars integration into power network. As regards the electrification of smart homes, the authors outline the basic «energy» conditions for their design, and requirements to be met by regional contractors, producers of energy equipment, utilities and grid companies. We develop a system of technological and economic solutions for moving relevant projects to an active phase. These projects include controllable

    Highlights: • The design of 2 off-grid electrification projects in Cape Verde is developed. • Configurations with hybrid renewable energy systems and micro-grids are considered. • A detailed micro-scale wind resource assessment is carried out. • An optimization model is used in order to support the design. • The proposed system is economically beneficial in comparison with diesel generation. - Abstract: Even though Cape Verde has high wind and solar energy resources, the conventional strategy for increasing access to electricity in isolated rural areas is by centralized microgrids with diesel generators. In this study, the design of 2 off-grid electrification projects based on hybrid wind–photovoltaic systems in Cape Verde is developed and analyzed. The design considers some significant novelty features in comparison with previous studies. First a detailed wind resource assessment is carried out combining meso-scale wind climate data and a specialized micro-scale wind flow model. Then a mathematical model is used for the design of off-grid projects considering a combination of individual systems and microgrids. In this study, locations far from the demand points are also considered as possible generation points. Various design configurations are analyzed and compared. The proposed configurations exploit the highest wind potential areas and are economically beneficial in comparison with diesel generator systems

    In September 2015, the United Nations General Assembly adopted Agenda 2030, which comprises a set of 17 Sustainable Development Goals (SDGs) defined by 169 targets. "Ensuring access to affordable, reliable, sustainable and modern energy for all by 2030" is the seventh goal (SDG7). While access to energy refers to more than electricity, the latter is the central focus of this work. According to the World Bank's 2015 Global Tracking Framework, roughly 15% of world population (or 1.1 billion people) lack access to electricity, and many more rely on poor quality electricity services. The majority of those without access (87%) reside in rural areas. This paper presents results of a Geographic Information Systems (GIS) approach coupled with open access data and linked to the Electricity Model Base for Africa (TEMBA), a model that represents each continental African country's electricity supply system. We present least-cost electrification strategies on a country-by-country basis for Sub-Saharan Africa. The electrification options include grid extension, mini-grid and stand-alone systems for rural, peri-urban, and urban contexts across the economy. At low levels of electricity demand there is a strong penetration of standalone technologies. However, higher electricity demand levels move the favourable electrification option from stand-alone systems to mini grid and to grid extensions.

    This article presents a case study of a project which provides photovoltaic-based rural electrification in the state of Alagoas in northeastern Brazil. The project, the Luz do Sol Programme (LdS), was initiated in mid-1996 by the Golden Genesis Company (Golden) and the Fundacao Teotonio Vilela (FTV). The article emphasizes some noteworthy characteristics of the project: the partnership between US commercial and Brazilian philanthropic interests; the financial aspect, a dedicated line of credit requiring only the equipment itself as security; and the local ownership and management of system operations, collections, and routine maintenance. In 1996, the Golden Genesis Company had developed a central battery charging system to bring the price of electrification within the range of the rural poor; it financed the US content of the systems, with the Bank of the Northeast of Brazil (BN) financing the Brazilian content. The article traces the long and arduous path to establish the programme, including both bureaucratic and technical challenges. These difficulties brought the project to an impasse in August of 1998, and Golden withdrew. FTV then re-negotiated the agreement with BN, changing the technical approach to individual solar home systems. This improved the situation, and the project has since enjoyed 100% loan repayment rates from the entrepreneurs. In June 1999, BP/Solarex became FTV's new commercial partner. The project currently shows promise of becoming the commercially viable programme originally envisaged by Golden, with commercial and technical decision-making at the local level. (author)

    2000-04-01

    This report is a summary of the results of the study relating to the socio-economical impact of the electrification by photovoltaic solar system in the zones of the project AIJ/RPTES. The localities concerned with the study are the provinces of BALE and the MOUHOUN. The data analyzes relating to the electrification by solar system of the zones of the project AIJ/RPTES, revealed that solar electrical energy contributed to a significant degree to the socio-economic development, especially at the level of the structures having profited from the solar equipment. The principal conclusions drawn from these analyzes attested that: the solar system corresponds as well as possible for rural environment as well on the technological level as on the capacity plan of maintenance. The following reasons come to corroborate this fact: the weakness of the costs of management of the photovoltaic modules; the photovoltaic technic, in spite of a low incidental maximum power (1 kw/ m 2 ), satisfied the priority needs for the rural populations (lighting, access to information and education, conservation of the vaccines in the CSPS, etc). - be photovoltaic installations cause: an average financial profit by CSPS of 180 487.5 FCFA/an, and a financial economy in the parents of the new-born babies estimated at 36,600 FCFA/an in each CSPS; an average financial economy by household of 49,452 FCFA/an [fr

    The decade leading up to the end of the last millennium saw systematic unbundling and privatisation of power utility companies in Sub-Saharan Africa. The new profit driven entrepreneurs have swiftly moved to consolidate in urban enclaves and put paid to any remote hope for future rural electrification. Consequently, rural communities have resorted to fending for themselves by adapting to off grid electrification. Most of these emerging installations are individual isolated units. This paper looks at various off gird electric system configurations in rural Kenya and suggests ways in which they could be reconfigured to be more energy efficient

    Electrification of transport fleets and heating sectors is seen as one of the key strategies to further reduce the use of fossil fuels and the resulting greenhouse gas emissions. However, it will potentially cause a significant increase of electricity peak demand and have adverse consequences on the electricity system, in particular on distribution networks. This paper will address the benefits of various applications of smart network control and demand response technologies for enhancing the integration of these future load categories, and for improvements in operation management and efficient use of distribution network assets. A range of numerical simulations have been carried out on different distribution network topologies (rural and urban networks) to identify the need and the cost of network reinforcement required to accommodate future load under various operating strategies such as Business as Usual (passive demand and passive network) against the smart grid approach. Applications of smart Plug-in vehicle (PiV) charging, smart heat pumps, and optimised control of network voltage regulators to reduce network investment have been studied, and selected key results of our studies on evaluating the benefits of implementing these technologies for Great Britain's distribution networks are presented and discussed in this paper. - Highlights: ► Growth of electricity loads driven by electrification of transport and heat will be significant. ► It will increase the electricity peak demand up to 2–3 times and cost tens of billion pounds if we maintain Business as Usual approach. ► A coordinated application of smart demand technologies can significantly reduce this cost. ► It requires sets of policies and regulations to facilitate timely deployment of such technologies.

    Full Text Available Abstract Background The diagnosis of typhoid fever is confirmed by culture of Salmonella enterica serotype Typhi (S. typhi. However, a more rapid, simpler, and cheaper diagnostic method would be very useful especially in developing countries. The Widal test is widely used in Africa but little information exists about its reliability. Methods We assessed the performance of the Widal tube agglutination test among febrile hospitalized Tanzanian children. We calculated the sensitivity, specificity, positive predictive value (PPV, and negative predictive value (NPV of various anti-TH and -TO titers using culture-confirmed typhoid fever cases as the "true positives" and all other febrile children with blood culture negative for S. typhi as the "true negatives." Results We found that 16 (1% of 1,680 children had culture-proven typhoid fever. A single anti-TH titer of 1:80 and higher was the optimal indicator of typhoid fever. This had a sensitivity of 75%, specificity of 98%, NPV of 100%, but PPV was only 26%. We compared our main findings with those from previous studies. Conclusion Among febrile hospitalized Tanzanian children with a low prevalence of typhoid fever, a Widal titer of ≥ 1:80 performed well in terms of sensitivity, specificity, and NPV. However a test with improved PPV that is similarly easy to apply and cost-efficient is desirable.

    In September 2015 UN announced 17 Sustainable Development goals (SDG) from which goal number 7 envisions universal access to modern energy services for all by 2030. In Kenya only about 46% of the population currently has access to electricity. This paper analyses hypothetical scenarios, and selected implications, investigating pathways that would allow the country to reach its electrification targets by 2030. Two modelling tools were used for the purposes of this study, namely OnSSET and OSeMOSYS. The tools were soft-linked in order to capture both the spatial and temporal dynamics of their nature. Two electricity demand scenarios were developed representing low and high end user consumption goals respectively. Indicatively, results show that geothermal, coal, hydro and natural gas would consist the optimal energy mix for the centralized national grid. However, in the case of the low demand scenario a high penetration of stand-alone systems is evident in the country, reaching out to approximately 47% of the electrified population. Increasing end user consumption leads to a shift in the optimal technology mix, with higher penetration of mini-grid technologies and grid extension.

    This report provides projected cost and performance assumptions for electric technologies considered in the Electrification Futures Study, a detailed and comprehensive analysis of the effects of widespread electrification of end-use service demands in all major economic sectors - transportation, residential and commercial buildings, and industry - for the contiguous United States through 2050. Using extensive literature searches and expert assessment, the authors identify slow, moderate, and rapid technology advancement sensitivities on technology cost and performance, and they offer a comparative analysis of levelized cost metrics as a reference indicator of total costs. The identification and characterization of these end-use service demand technologies is fundamental to the Electrification Futures Study. This report, the larger Electrification Futures Study, and the associated data and methodologies may be useful to planners and analysts in evaluating the potential role of electrification in an uncertain future. The report could be broadly applicable for other analysts and researchers who wish to assess electrification and electric technologies.

    2017-01-01

    This book introduces comprehensive fundamentals, numerical simulations and experimental methods of electrification of particulates entrained multiphase flows. The electrifications of two particulate forms, liquid droplets and solid particles, are firstly described together. Liquid droplets can be charged under preset or associated electric fields, while solid particles can be charged through contact. Different charging ways in gas (liquid)-liquid or gas-solid multiphase flows are summarized, including ones that are beneficial to industrial processes, such as electrostatic precipitation, electrostatic spraying, and electrostatic separation, etc., ones harmful for shipping and powder industry, and ones occurring in natural phenomenon, such as wind-blown sand and thunderstorm. This book offers theoretical references to the control and utilization of the charging or charged particulates in multiphase flows as well.

    The study traces the history of electrification in Ethiopia and its contribution to the national, regional, and local economy in arms of electricity supply and its significance to the supply of materials and services, to employment, and to the level of living. It presents present-day impacts on households, industrial and commercial establishments, and public institutions concerned with infrastructure, services, and planning and development, on the basis of in-depth field interviews in October-December 1990. In addition, it studies problems and opportunities related to electricity supply to consumers, on the basis of information from the Ethiopian Electric Light and Power Authority (EELPA). As a frame of reference, it has used past studies related to electrification in Ethiopia and abroad. The study indicates the need for a demand forecast and impact model for Ethiopia, including the cross effects of electrification in the large and small industrial, commercial and other service, and domestic sectors. Some of the data required would have to be generated.

    1997-08-01

    Local management of rural power supply is being evaluated in a joint research project conducted by Tanzania Electric Supply Company Limited (TANESCO) and Stockholm Environment Institute (SEI) on new approaches to management and organization of rural electrification. The study is based on literature, and on data from eight visited local organizations for management of power supply in Bolivia (4), India (1) and Nepal (3). Common for these countries is that the national, rural electrification programmes have encountered difficulties. Governments have failed to generate enough funds from existing power supply systems to cover the cost for a continued rural electrification. In cases where large private companies exist, they have had few incentives for expanding into rural areas since it is often not profit making. A third category may be defined as local initiators to power supply, private or co-operative. In all these countries, locally managed power supply systems have developed as a complement to governmental and other large scale programmes. The national policies pertaining to rural power supply in general and local management thereof in particular are described for each country. From the study, it appears that local management of rural power supply is a feasible approach in developing countries. Local management of rural power supply can slightly lower the costs of electrification, and it may help accelerate the pace of load development in newly electrified areas. For successful local organizations though, the most significant factor appears to be local peoples` willingness to develop their own area. Important though, is that proper financial and technical assistance is provided the local organizations. Crucial for sound external assistance is that the national rural electrification policies are clear and consistent. 53 refs, 1 fig, 11 tabs

    Electrification of end-use services in the transportation, buildings, and industrial sectors coupled with decarbonization of electricity generation has been identified as one of the key pathways to achieving a low-carbon future in the United States. By lowering the carbon intensity of the electricity generation and substituting electricity for higher-emissions fossil fuels in end-use sectors, significant reductions in carbon dioxide emissions can be achieved. This report describes a preliminary analysis that examines the potential impacts of widespread electrification on the U.S. energy sector. We develop a set of exploratory scenarios under which electrification is aggressively pursued across all end-use sectors and examine the impacts of achieving these electrification levels on electricity load patterns, total fossil energy consumption, carbon dioxide emissions, and the evolution of the U.S. power system.

  14. Key factors for the implementation of successful, stand-alone village electrification schemes in Peru

    Science.gov (United States)

    Sanchez-Campos, Teodoro

    The hypothesis of this work is that there are social, financial, technical, managerial institutional and political key factors that may either support or prevent the success of small stand alone energy systems in rural areas. This research work aims at contributing to the identification of such factors and study their relevance to the performance and sustainability of stand alone energy systems in rural areas; to meet its purpose, a wide range of literature was reviewed including rural electrification programmes and projects, research and development projects on access to electricity in rural areas, impact studies and others, and a field research survey was done the Andes and Upper Jungle regions in Peru. Nineteen possible critical factors were identified, thirteen with relevance at the local context (the community or village), and six with relevance at the national (or wider) context. From literature review it was found that the possible local critical factors were relevant only to four categories of factors instead of the six considered initially (i.e. social, financial, technological and managerial): the other two categories, political and institutional were found to be more relevant to the national context, therefore those were included in the group of possible critical factors of wider context. A series of questionnaires were designed to collect field data information, which was later used to analyse and establish the relation of each identified factor with the success of the systems studied. The survey research was implemented in 14 villages, 7 with small diesel sets and 7 with small hydropower schemes, all spread in the Andes and Upper Jungle of Peru, which were carefully selected to be representative of regions with isolated stand alone systems and with different socioeconomic background. Out of the 13 possible critical factors of local context, it was found that only 3 are really critical, the others are important but not critical; one of them (technical

    The installation of a small-scale hydroelectric generating station to supply electricity to the small community of Takordmi in Morocco was described. The community of Takordmi consists of 32 households located in the remote mountainous region of Morocco. Takordmi was without electrical power until 1992 when a small 15 kW Pelton turbine was installed to supply electricity to the residents. Water to power the turbine generator was supplied by a small stream with an output of 4 to 8 liters per second and a head of 535 meters. Since the unit was installed, the mean monthly consumption of the community has been only 115 kWh, which averages to 4 kWh per household. The success of the Takordmi project has prompted the electrification of several other small communities in the remote regions of Morocco either by similar micro-hydroelectric stations or by photovoltaic cells. This project, funded by the Republic of Austria, demonstrates that it is feasible to provide electricity to remote rural communities by using local sources of power. 3 figs

  16. The electrification of Nova Scotia, 1884--1973: Technological modernization as a response to regional disparity

    Science.gov (United States)

    King, Lionel Bradley

    This dissertation investigates local attempts to use technology as a force for regional rehabilitation in the economically-depressed Maritime region of Canada. At the time of Confederation in 1867, the Maritime province of Nova Scotia was prosperous, progressive, and cultured. By the end of the 1910s, the province had entered a long period of economic and social decline. Recent historiography has shown that, far from passively accepting their fate, Nova Scotians and other Maritimers, actively resisted marginalization with political, cultural, or social action. The thesis expands upon that literature by exploring technology-based strategies of provincial rehabilitation using Thomas P. Hughes's systems perspective and David E. Nye's semiotic approach. In doing so, it applies methods from the social constructivist school of the history of technology to the larger concerns of Maritime Canadian historiography. In large part, the North American culture of technology determined the ways in which Nova Scotians applied technological solutions to provincial concerns. Technology has long been central to the Western idea of progress. As the "high technology" of the late nineteenth and early twentieth centuries, electricity reinforced that view: its ephemeral nature and silent efficiency led people to endow it with transformative, even mystical, powers. As a result, Nova Scotians, adopted a program of electrical modernization in the late 1910s as a remedy for regional disparity. The Nova Scotia government's first step was the creation of an Ontario-style hydroelectric commission designed to bring order to the province's fragmented and inefficient electrical network. Over the next few decades, the Nova Scotia Power Commission implemented rural electrification, home modernization, and regional system-building models that had already proven successful in Ontario and the United States. The system-building philosophies behind these programs were adapted to local conditions and

    The class 2b-3 truck market covers a wide range of commercial truck applications across a half-million vehicle sales annually. This report collected public information and stakeholder input to assess the opportunity for electrification in this market. Although class 2b-3 pickup truck and van bodies are very similar to personal light vehicles, their functional requirements are quite different due to the demands of the commercial market. These demands vary by application and often vary from day to day for a single application. Fleet customers purchase these vehicles to perform a particular job for their business and are concerned about the overall cost of doing that job. Therefore, the vehicles must meet the job requirements cost effectively. Customers also are sensitive to initial cost. Electrification offers the potential to reduce vehicle operating costs and possibly improve vehicle functionality. However, the current market for class 2b-3 electrified trucks is very small, and the trucks are costly. Increased production volumes are key to cost reductions and may be assisted by sharing components with larger or smaller truck classes. Expanding demand is also crucial and stakeholders identified several niche markets with duty cycles that are likely well-suited to electrified class 2b-3 trucks. To expand beyond these niches, class 2b-3 electric solutions must be robust, flexible, and adaptable in order to cover a wide range of vocations, applications, and duty cycles.

    Commercial fleets form the backbone of the nation’s economy, getting people and the things they need to the places they need to go and performing services necessary to keep public and private physical infrastructure in working order. Commercial fleets include a wide range of vehicle and equipment types, typical uses, and sizes, and involve millions of on-road and offroad vehicles. This diversity means there is no single solution to the challenges these vehicles pose for reducing petroleum dependence, impact on air quality, and emission of greenhouse gases. This document focuses on electrification of government, commercial, and industrial fleets. These fleets have been divided into three market segments based on equipment use: service fleets, goods movement, and people movement. In particular, it addresses highway vehicles not used for personal transport; non-highway modes, including air, rail, and water; and non-road equipment used directly or in support of these uses.

The aim of this paper is to explore ICT-related transformations of everyday practices and discuss the implications, particularly for residential electricity consumption. The present socio-technical changes are seen in a historical perspective, and it is argued that the integration of ICT into everyday practices can be seen as a new round of household electrification, comparable to earlier rounds that also led to higher electricity consumption. A case study carried out in Denmark in 2007-2008 explores the present changes in everyday life. Based on qualitative interviews, the study focuses on people's ways of integrating ICTs into their everyday practices, on any significant changes in these practices, and on the influence of the changed practices on electricity consumption. The paper concludes with a discussion on the implications for energy policy.

    The per capita per year fuel consumption in Bangladesh is only 56 kg oil equivalent. The supply of electricity by Bangladesh power development board (BPDB) and Dhaka electricity supply authority (DESA) is mainly confined to cities and towns. Rural Electrification Board (REB) distributes electricity to the rural people through cooperatives. The rural cooperatives cover only 10% of the total population. Only about 15% of the total population is directly connected to the electricity. In order to meet the increasing energy demand for development of agriculture and industry and for the generation of better employment opportunities, it will be necessary to harness all the available alternative sources of energy immediately.

    2010-01-01

    In developing countries, providing all citizens an access to modern forms of energy is among the central energy policy objectives, as the linkages between modern energy services and human development are widely recognized. This paper presents in a scenario analysis of rural energy consumption, how energy services in different sectors of a village economy contribute to the achievement of the UNDP Millennium Development Goals. In a rural village in Lao People's Democratic Republic, household energy demand and energy uses were surveyed immediately prior to the electrification of the village. Based on the situation preceding electrification of the village, the development of village electrification was studied by simulating the village energy system, accounting for all village energy uses but transportation. To study the potential development of electricity demand in the village, three scenarios were constructed using the LEAP model: 'residential demand', 'income generation' and 'public services'. Energy demand in each scenario was analyzed with reference to the Millennium Development Goals.

    Meeting a greenhouse gas (GHG) reduction target of 80% below 1990 levels in the year 2050 requires detailed long-term planning due to complexity, inertia, and path dependency in the energy system. A detailed investigation of supply and demand alternatives is conducted to assess requirements for future California energy systems that can meet the 2050 GHG target. Two components are developed here that build novel analytic capacity and extend previous studies: (1) detailed bottom-up projections of energy demand across the building, industry and transportation sectors; and (2) a high-resolution variable renewable resource capacity planning model (SWITCH) that minimizes the cost of electricity while meeting GHG policy goals in the 2050 timeframe. Multiple pathways exist to a low-GHG future, all involving increased efficiency, electrification, and a dramatic shift from fossil fuels to low-GHG energy. The electricity system is found to have a diverse, cost-effective set of options that meet aggressive GHG reduction targets. This conclusion holds even with increased demand from transportation and heating, but the optimal levels of wind and solar deployment depend on the temporal characteristics of the resulting load profile. Long-term policy support is found to be a key missing element for the successful attainment of the 2050 GHG target in California. (letter)

  10. Mechanisms of Contact Electrification at Aluminum-Polytetrafluoroethylene and Polypropylene-Water

    KAUST Repository

    Nauruzbayeva, Jamilya

    2017-04-01

    Contact electrification refers to the transfer of electrical charges between two surfaces, similar and dissimilar, as they are brought into contact and separated; this phenomenon is also known as static electrification or triboelectrification. For example, everyone has experienced weak electrical shocks from metal doorknobs, wool and synthetic clothing on dry days. While contact electrification might appear insignificant, it plays a key role in numerous natural and industrial processes, including atmospheric lightning, accumulation of dust on solar panels, charging of liquids during pipetting and flow in the tubes, and fire hazards in granular media. Contact electrification at metal-metal interfaces is well understood in terms of transfer of electrons, but a comprehensive understanding of contact electrification at interfaces of electrical insulators, such as air, water, polytetrafluoroethylene (PTFE), polypropylene remains incomplete. In fact, a variety of mechanisms responsible for transfer of electrical charges during mechanical rubbing, slipping, sliding, or flow at interfaces have been proposed via: electrons, ions, protons, hydroxide ions from water, specific orientation of dipoles, mechanoradicals, cryptoelectrons, and transfer of material. We have noticed that the extent of contact electrification of solids in water is influenced by surface free energies, mobile ions, surface roughness, duration of contact, sliding speeds, and relative humidity. Herein, we present results of our experimental investigation of contact electrification at the following interfaces: (i) PTFE-aluminum in air and (ii) polypropylene-water interfaces. To identify the underlying mechanism, we started with various hypotheses and exploited a variety of experimental techniques to falsify most of them until we got an answer; our techniques included high-voltage power supply (0-10,000 V), Faraday cages, Kelvin probe force microscopy, electrodeposition, X-ray photoelectron spectroscopy

The radial arrays of micro-sized sectors on the contact surfaces enable a high output power of 1.5 W (area power density of 19 mW cm(-2)) at an efficiency of 24%. The triboelectric generator can effectively harness various ambient motions, including light wind, tap water flow and normal body movement. Through a power management circuit, a triboelectric-generator-based power-supplying system can provide a constant direct-current source for sustainably driving and charging commercial electronics, immediately demonstrating the feasibility of the triboelectric generator as a practical power source. Given exceptional power density, extremely low cost and unique applicability resulting from distinctive mechanism and structure, the triboelectric generator can be applied not only to self-powered electronics but also possibly to power generation at a large scale.

    In the recent years, much attention has been devoted to the possibility of charging polymer-based materials, due to their potential in developing large-scale and inexpensive flexible thin-film technology. The availability of localized electrostatic fields is in of great interest for a huge amount of applications such as distribution of biomolecules and cells from the liquid phase. Here we report a voltage-free pyro-electrification (PE) process able to induce permanent dipoles into polymer layers; the lithium niobate (LN) crystal is the key component that plays the multi-purpose role of sustaining, heating and poling the polymer layer that is then peeled-off easily in order to have a free-standing charged membrane. The results show the fascinating application for the living cell patterning. It well known that cell behaviour is affected by chemical and topographical cues of substrate. In fact, polymers, such as polystyrene (PS) and poly(methyl methacrylate) (PMMA), are naturally cytophobic and require specific functionalization treatments in order to promote cell adhesion. Through our proposal technique, it’s possible to obtain spontaneous organization and a driven growth of SH-SY5Y cells that is solely dictated by the nature of the charge polymer surface, opening, in this way, the innovative chance to manipulate and transfer biological samples on a free-standing polymer layer [1].

  13. Electricity distribution industry restructuring, electrification, and competition in South Africa

    This paper reviews the status of the South African electricity supply industry (ESI) and proposals for reorienting and restructuring it. South Africa has been intensely examining its ESI for more than 4 years in an effort to determine whether and how it should be restructured to best support the country's new economic development and social upliftment goals. The debate has been spirited and inclusive of most ESI stakeholders. The demands on and expectations for the ESI are many and varied. The debate has reflected this diversity of interests and views. In essence, however, there is a consensus on what is expected of the industry, namely, to extend provision of adequate, reliable, and affordable electricity service to all citizens and segments of the economy. This means a large-scale electrification program to reach as many of the nearly 50% of households currently without electricity service as soon as possible, tariff reform to promote equity and efficiency, and the upgrading of service quality now being provided by some of the newly consolidated municipal authorities. The issues involved are how best to achieve these results within the context of the national Reconstruction and Development Program, while accounting for time and resource constraints and balancing the interests of the various parties

    Assessments of the impact of electrification on the quality of life of households in developing countries have increased over the last decade. One aspect that has still received little attention is education and the ability of children to keep up at school. The underlying hypothesis is that electrification enables children to do their homework in the evening and so keep up with their school work. To this first hypothesis we add a second one, concerning the relation between access to electricity and attendance to school according to gender. Although most household tasks are carried out by the mothers, their daughters are also involved, and electrification could have a beneficial effect by making easier for girls to do their homework in the evening and easier for the mothers to help them. We will check the validity of these hypotheses using a case study of 162 children attending school in a small town in northwestern Madagascar. - Research Highlights: → We use a sample of 162 children in Madagascar to test the effect of access to the electricity supply in home to the education of children. → We also test the effect to the electricity supply in home to gender-specificities. → Our results confirm that electrification can contribute to reduce social reproduction with regard to education. → Our results also show that electrification helps to reduce gender inequalities.

    Access to electricity is important for alleviation energy poverty in rural areas of developing countries. In spite of rural electrification schemes people in numerous villages do not have access to electricity because of inadequate and erratic power supply. The Jyotigram Yojana (Rural Lighting Scheme) of Gujarat in India transformed the rural electricity distribution scenario creating immense opportunities for socio-economic development. It shows how vision and political will can transcend the boundaries of technical and financial expertise and systemic rigidities, and facilitate successful adoption of simple but innovative approaches for alleviation of energy poverty and bringing about socio-economic development.

    Kennedy Space Center (KSC) operations are located in a region which experiences one of the highest lightning densities across the United States. As a result, on average, KSC loses almost 30 minutes of operational availability each day for lightning sensitive activities. KSC is investigating using existing instrumentation and automated algorithms to improve the timeliness and accuracy of lightning warnings. Additionally, the automation routines will be warning on a grid to minimize under-warnings associated with not being located in the center of the warning area and over-warnings associated with encompassing too large an area. This study discusses utilization of electric field mill data to provide improved warning times. Specifically, this paper will demonstrate improved performance of an enveloping algorithm of the electric field mill data as compared with the electric field zero crossing to identify initial storm electrification. End-of-Storm-Oscillation (EOSO) identification algorithms will also be analyzed to identify performance improvement, if any, when compared with 30 minutes after the last lightning flash.

    Full Text Available Electricity is a vital factor underlying modern living standards, but there are many developing countries with low levels of electricity access and use. We seek to systematically identify the crucial elements underlying transitions toward greater electrification in developing countries. We use a cross-sectional regression approach with national-level data up to 2012 for 135 low- and middle-income countries. The paper finds that the effectiveness of governments is the most important governance attribute for encouraging the transition to increased electrification in developing countries, on average. The results add to the growing evidence on the importance of governance for development outcomes. Donors seeking to make more successful contributions to electrification may wish to target countries with more effective governments.

  2. Greenhouse gas implications of fleet electrification based on big data-informed individual travel patterns.

    Environmental implications of fleet electrification highly depend on the adoption and utilization of electric vehicles at the individual level. Past research has been constrained by using aggregated data to assume all vehicles with the same travel pattern as the aggregated average. This neglects the inherent heterogeneity of individual travel behaviors and may lead to unrealistic estimation of environmental impacts of fleet electrification. Using "big data" mining techniques, this research examines real-time vehicle trajectory data for 10,375 taxis in Beijing in one week to characterize the travel patterns of individual taxis. We then evaluate the impact of adopting plug-in hybrid electric vehicles (PHEV) in the taxi fleet on life cycle greenhouse gas emissions based on the characterized individual travel patterns. The results indicate that 1) the largest gasoline displacement (1.1 million gallons per year) can be achieved by adopting PHEVs with modest electric range (approximately 80 miles) with current battery cost, limited public charging infrastructure, and no government subsidy; 2) reducing battery cost has the largest impact on increasing the electrification rate of vehicle mileage traveled (VMT), thus increasing gasoline displacement, followed by diversified charging opportunities; 3) government subsidies can be more effective to increase the VMT electrification rate and gasoline displacement if targeted to PHEVs with modest electric ranges (80 to 120 miles); and 4) while taxi fleet electrification can increase greenhouse gas emissions by up to 115 kiloton CO2-eq per year with the current grid in Beijing, emission reduction of up to 36.5 kiloton CO2-eq per year can be achieved if the fuel cycle emission factor of electricity can be reduced to 168.7 g/km. Although the results are based on a specific public fleet, this study demonstrates the benefit of using large-scale individual-based trajectory data (big data) to better understand environmental implications

    Full Text Available Energy is one of the most important factors in the socioeconomic development of a country. In a developing country like Malaysia, the development of islands is mostly related to the availability of electric power. Power generated by renewable energy sources has recently become one of the most promising solutions for the electrification of islands and remote rural areas. But high dependency on weather conditions and the unpredictable nature of these renewable energy sources are the main drawbacks. To overcome this weakness, different green energy sources and power electronic converters need to be integrated with each other. This study presents a battery storage hybrid standalone photovoltaic-wind energy power supply system. In the proposed standalone hybrid system, a DC-DC buck-boost bidirectional converter controller is used to accumulates the surplus hybrid power in the battery bank and supplies this power to the load during the hybrid power shortage by maintaining the constant dc-link voltage. A three-phase voltage source inverter complex vector control scheme is used to control the load side voltage in terms of the voltage amplitude and frequency. Based on the simulation results obtained from MATLAB/Simulink, it has been found that the overall hybrid framework is capable of working under variable weather and load conditions.

    The Altus Cumulus Electrification Study (ACES) was conducted during the month of August, 2002 in an area near Key West, Florida. One of the goals of this uninhabited aerial vehicle (UAV) study was to collect high resolution optical pulse and electric field data from thunderstorms. During the month long campaign, we acquired 5294 lightning generated optical pulses with associated electric field changes. Most of these observations were made while close to the top of the storms. We found filtered mean and median 10-10% optical pulse widths of 875 and 830 microns respectively while the 50-50% mean and median optical pulse widths are 422 and 365 microns respectively. These values are similar to previous results as are the 10-90% mean and median rise times of 327 and 265 microns. The peak electrical to optical pulse delay mean and median were 209 and 145 microns which is longer than one would expect from theoretical results. The results of the pulse analysis will contribute to further validation of the Optical Transient Detector (OTD) and the Lightning Imaging Sensor (LIS) satellites. Pre-launch estimates of the flash detection efficiency were based on a small sample of optical pulse measurements associated with less than 350 lightning discharges collected by NASA U-2 aircraft in the early 1980s. Preliminary analyses of the ACES measurements show that we have greatly increased the number of optical pulses available for validation of the LIS and other orbital lightning optical sensors. Since the Altus was often close to the cloud tops, many of the optical pulses are from low-energy pulses. From these low-energy pulses, we can determine the fraction of optical lightning pulses below the thresholds of LIS, OTD, and any future satellite-based optical sensors such as the geostationary Lightning Mapping Sensor.

    This work presents the first dual fuel measurements with pure jatropha oil and biogas, using a 12 kW diesel engine generator. Reference tests are done with pure jatropha oil and with diesel to characterize the engine's thermal efficiency {eta}{sub t}, volumetric efficiency {eta}{sub v} and air-excess ratio {lambda} versus output power. An extensive parameter study is done to predict/explain the effect of dual fuel operation on {eta}{sub v} and {lambda}. Dual fuel experiments, adding different qualities (CH{sub 4}/CO{sub 2} ratios) of synthetic biogas to the intake air, show that thermal efficiency is hardly affected for higher loads. For lower loads, biogas addition results in a decrease up to 10% in thermal efficiency, independent of biogas quality. Both {eta}{sub v} and {lambda} decrease with addition of biogas, in quantitative agreement with predictions. The engine runs well up to a certain heat release fraction of methane; at higher fractions irregularities are observed, probably attributable to light end-gas knock. (author)

    In order to combat poverty and fight for the Millennium Development Goals through providing access to modern energy, it is necessary to analyze social acceptance of new forms of energy in order to implement them successfully. Nine different Pico Photovoltaic systems were tested during a field study in a non-electrified village in Ethiopia. Each lamp was tested for a week by one of 24 families. Quantitative methods (interviews, focus groups, participant observation) were conducted in order to explore technology change and its social impacts. With these methods, an alternating change of induction and deduction is achieved to gain insight. The most important results are: Apart from expected benefits in health, work, education and economy, people also noticed improvements in the autonomy of children, flexibility, stress, security and family life. Negative aspects were found regarding inter-social relations and in the absence of possible activities. Quality of lamps is defined by respondents according to brightness, duration and cone of light. Furthermore, people prefer white, bright light as well as a built-in switch. Systems considered best in European laboratory tests were evaluated poorly in Ethiopia. In the end, people ordered 30 systems. The decision to buy was a collective one. Even though energy supply is the responsibility of women, men made the final deicision about the purchase of the lamps. (orig.)

    Highlights: • CO_2 emission reduction calls for energy-efficient mobile work machines. • Energy recovery could be possible in some agricultural machinery operations. • Owning and operating costs of electrified tractor-implement pairs should be analyzed. • Plug-in hybrid electric tractors running along tramlines make sense. • Electrification allows for precise speed control, noise reduction and flexible design. - Abstract: Reduction of both pollutant emissions and fossil fuel dependency is an objective of energy policies worldwide. In many countries, governments promote the use of efficient vehicles like the hybrid electric vehicle. Incorporation of electric drives in tractor and agricultural machinery presents advantages in terms of increased energy efficiency and expanded functionalities. Higher efficiency means reduction in fuel consumption and subsequent decrease in CO_2 emission. New functionalities improve work quality and increase operator comfort. Tractor electrification takes advantage of decoupling loads and drives from the engine, which allows operating the latter at its highest efficiency point. Major advantages of machinery electrification are torque and speed control, noise reduction, and a more flexible design. In this paper, a review of the state-of-the-art of agricultural machinery high voltage electrification is presented.

    Plasma has the largest influence on the electrification and discharge in the space environment. In the present study, satellite surface material is irradiated with an electron beam witch simulates the electron flow in the plasma, in order to investigate the mechanism of electrification and discharge and to provide basic information required for developing electrification prevention techniques. The heat-control material samples used include silver-deposited Teflon, aluminum-deposited Kapton, optical solar reflector and transparent conductive-coated aluminum-deposited Kapton. It is shown that silvered Teflon is electrified more easily than aluminized Kapton. Two types of discharge are found to occur in silvered Teflon: creeping discharge in thick samples (5 mil) and penetration break accompanied by creeping discharge in thin samples (1 mil). The discharge frequency increases with increasing beam current density and electron energy. The occurrence of discharge results in an increase in the sunlight absorption factor of silvered Teflon. When a set of four sheets of optical solar reflector is subjected to electron beam, active discharge is seen to take place between the sheets. It is also revealed that static electrification can be prevented effectively if the surface of heat-control material is coated with transparent conductive material such as indium oxide. (Nogami, K.)

    It has been estimated that with the present utilization of resources, the country will run out of oil and gas reserves in one and a half decade. There is, thus, a strong need to take measures to tap other resources of energy, which are abundantly available in Pakistan. The exploitation of these resources for production of electricity on local basis, under participatory system of development, would supplement energy being provided by WAPDA, at a much lower cost due to the avoidance of laying high-tension cables, transformers, and meters, etc., and the manpower required to maintain the system. Balochistan is a large but thinly populated province of Pakistan. The situation of electrification in Balochistan is serious, as a vast majority of the population is without access to electricity. Many villages and districts of Balochistan do not have centralized electricity-grid and there is no hope, in the near future, to have one because the extension of grid to such remote and scattered settlements is neither practical nor economically viable. In Balochistan, out of a total number of 13,700 villages, WAPDA has merely electrified 3,154 villages due to the high cost involved in developing the necessary infrastructure. Not surprisingly, this situation is a source of discontentment among the people of the Province. Pakistan has a considerable potential of wind-energy in the coastal belt of Balochistan and Sindh, as well as in the desert areas of Punjab and Sindh, which if utilized effectively, can not only electrify all remote coastal villages, but the electricity so produced also can be fed to the national grid. This renewable source of energy has however, so far, not been utilized. Recently, fourteen small wind-turbines (300-500 watts) were procured and installed by PCRET under Sino-Pak S and T Protocol. Being encouraged by performance of these small wind- turbines, a further 120 wind turbines (JOO of 500 watts and 20 wind-turbines of 5kW each) are being installed. The small

    Energy poverty is a well-established concept among energy and development specialists. International development organizations frequently cite energy-poverty alleviation as a necessary condition to reduce income poverty. Several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting. This paper uses a demand-based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income. At or below this threshold point, households consume a bare minimum level of energy and should be considered energy poor. This approach was applied using cross-sectional data from a comprehensive 2004 household survey representative of rural Bangladesh. The findings suggest that some 58 percent of rural households in Bangladesh are energy poor, versus 45 percent that are income poor. The findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty. - Research Highlights: →We estimate energy poverty for rural Bangladesh adopting a demand-based approach. →Findings suggest that energy poverty does not necessarily follow the same pattern as income poverty. →Access to modern energy and efficient use of traditional energy help alleviate energy poverty. →Energy poverty indicator can help track the effectiveness of a wide range of energy policies.

    The rural electrification program in Tanzania has been on going since independence in 1961, with the national utility, Tanzania Electric Supply Company Ltd. (TANESCO) being responsible for its implementation. By 1992, 14 townships and 37 villages had been electrified as a result of this program. This covers only a small fraction of rural Tanzania. It is estimated that in 1998, less than 1% of the rural households in Tanzania had access to electricity. Electricity constitutes only 1% of Tanzania's final energy consumption. Except for the few latest years, electricity generation and distribution in Tanzania has been the full responsibility of TANESCO. The national electricity grid is mainly supplied by large-scale hydro power plants (391 MW), and thermal power plants (148 MW). Rural areas are supplied either by a transmission line from the national grid or by diesel generator sets. The isolated branches run by TANESCO have an installed capacity amounting to a total of 23 MW. Electric lighting is the dominating use of electricity in rural areas. Industrial use in these areas is marginal. Very few rural households use electricity for cooking. Cooking is made with fuelwood and to some extent charcoal and kerosene. Where electricity is not available, kerosene in simple wick lamps is used for lighting. As part of the research co-operation between TANESCO and the Stockholm Environment Institute, SEI, an extensive evaluation of the experiences from the rural electrification program in Tanzania was carried out in 1989 - 1991. The four main conclusions from this evaluation were in summary: The rural people appreciate electrification. Rural electrification is a large financial burden on TANESCO. The quality of the service, in particular the supply reliability, is low in rural areas. Many of the perceived benefits of rural electrification, like the creation of small scale industries or reduced use of fuel wood for cooking, have not materialised to a significant degree. As

    This collaborative educational project between the University of Michigan—Ann Arbor, University of Michigan—Dearborn and the Kettering University successfully executed almost all the elements we proposed to do. In the original proposal, we proposed to develop four graduate courses, six undergraduate courses, four professional short courses, a K-12 electric vehicle education kit, a Saturday morning seminar series, and a set of consumer education material to support the advancement of transportation electrification. The first four deliverables were all successfully developed and offered. When we held the kick-off meeting in NETL in Morgantown back in early 2010 with all the ten ARRA education teams, however, it quickly became clear that among the ten ARRA education grantee teams, our proposed “consume education” activities are not better or with the potential to create bigger impact than some of activities proposed in other teams. For example, the Odyssey 2010 event held by the West Virginia University team had planned and successfully reached to more than 230,000 attendees, which is way more than what our proposed 100k event could ever reach. It was under the suggestion of Joseph Quaranta, the ARRA education Program Director at that time, that we should coordinate and eliminate redundancy. The resources should then be focused on activities that have less overlap. Therefore, the originally proposed activities: Saturday morning seminar series, and a set of consumer education material were dropped from our scope. We expanded the scope of our “education kit” activity to include some educational materials, mainly in the form of videos. The target audience also changed from general public to K-12 students. The majority of the project cost (~70%) goes toward the establishment of three undergraduate laboratories, which provides critically needed hands-on learning experience for next-generation green mobility engineers. We are very proud that the ARRA money

    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

    The United States Army embraced electrical technology in the 1870s as part of a wider initiative to meet the challenge of the coastal defense mission. As commercial power storage, generation, and transmission technology improved and the army came to recognize the value of the energy source as a means and method of improving command and control, localized electrical networks were integrated into the active service of the military. New vulnerabilities emerged as the army became ever more reliant upon electric power, however, and electrification---the institutional adoption and adaptation of electrical technologies---emerged as a very expensive and contentious process guided by technical, political, and economic pressures, and influenced by conflicting personalities within the service. This study considers the institutional evolution of the U.S. Army before and during World War I with respect to the adoption and application of electrical technology. The changing relationships between the military and electrical manufacturing and utilities industries during the period 1875--1920 are also explored. Using a combination of military archival sources and published primary materials, this study traces the effects of electrification on the army. In the end, this study proves that electrification was, at first, a symptom of, and later, a partial solution to the army's struggle to modernize and centralize during the period under consideration. Electrification produced a set of conditions that encouraged a new maturity within the ranks of the army, in technical, doctrinal, and administrative terms. This growth eventually led to the development of new capabilities, new forms of military organization, new missions, and new approaches to warfare.

    Locomotives offer an efficient mode of transportation when compared to buses, personal vehicles or airplanes for mass transportation over frequent intercity distances. For example, a Bombardier Regina EMU train with 272 seats and a load factor of 53% will consume under 0.07 kWh/passenger-km, which is typically much lower than corresponding values for other transportation modes in similar circumstances. European countries have invested significantly over the years in train electrification. Environmentally friendly methods of transferring power to the wheels are direct electrification and hydrogen fuel cells. Various methods to produce hydrogen for utilization with fuel cell train operation are examined in this paper. This companion paper of a 2-paper set examines the overall impact of energy supply (hydrogen vs. electricity) and distribution on rail transportation, specifically in terms of costs and overall GHG emissions for a case study of GO transit along the Lakeshore corridor in Toronto. Although electrification of train services simplifies some aspects of the operation, when considered over the Lakeshore corridor alone, electrified trains lose their flexibility to serve cities outside the Lakeshore corridor. Hydrogen fuelled trains can provide a smoother transition and interoperability by operating the same routes and stations served by diesel trains today, without being limited to the Lakeshore corridor. This paper evaluates technological, operational and economic aspects of the electrification of the Lakeshore corridor, versus hydrogen train operation, including infrastructure requirements to provide service to a substantial ridership increase projected for the years 2015-2031. Various methods of hydrogen production and distribution are presented and analysed, in order to evaluate the overall life cycle of GHG emissions and costs for various train alternatives. (author)

    This paper documents South Africa's electrification programme from the late 1980s to the present. The primary aim of the paper is to present the reader with an overview of the policy, institutional, planning, financing and technological developments and innovations that resulted in more than 5 million households receiving access to electricity between 1990 and 2007. Key aspects include the way in which a period of political change and policy disruption were essential to the programme's initiation, and the critical role played by organisations and individuals outside of national government in helping shape new electrification policies and strategies. In addition, the paper identifies the contribution of technology development in cost reduction and achieving the social aims of the programme. Several lessons may be drawn from the institutional and planning arrangements that the South African programme has developed, the significance of the development of appropriate cost-driven technical innovations and standards, and the acknowledgement of the social function of electrification and its funding from the fiscus (rather than through cross-subsidies)

    Such considerations as the level of traffic, the relative financial health of individual railroads, the capacity of the associated supply and engineering/construction industries, and the logical connecting points at classifying yards, as well as the national interest value of creating a continuous system, continental in scope, were used to construct a scenario for railroad electrification that closely approximates how an electrification program might be implemented. For the economic reasons cited, much of the US railroad system would remain conventionally powered. This scenario provides for an electrified network involving 14 mainlines operated by 10 companies that could transport much of the nation's rail-borne freight. Five years of planning and engineering work would be required for each link before construction could begin. With 1000 miles or less of electrified route per year, 14 years would be needed to construct the 9000-mile network of our scenario. (The scenario constructed runs from 1980 to 1998.) The analysis was aided with the construction of the SRI Railroad Industry Model. Basically a model of industry operations and finances, the model produces income statements and balance sheets at yearly intervals. Railroad energy costs, railroad freight levels, maintenance costs, purchases and leases of rooling stock, electrification facility investments, future inflation, rate setting practices, annual depreciation, taxes, and profits were calculated.

    2012-01-01

    The choice between centralized and decentralized electricity generation is examined for 150 countries as a function of population distribution, electricity consumption, transmission cost, and the cost difference between decentralized and centralized electricity generation. A network algorithm is developed to find the shortest centralized transmission network that spans a given fraction of the population in a country. The least-cost combination of centralized and decentralized electricity that serves the country is determined. Case studies of Botswana, Uganda, and Bangladesh illustrate situations that are more and less suited for decentralized electrification. Specific maps for centralized and decentralized generation are presented to show how the least-cost option varies with the relative costs of centralized and decentralized generation and transmission cost. Centralized and decentralized fractions are calculated for 150 countries. For most of the world's population, centralized electricity is the least-cost option. For a number of countries, particularly in Africa, substantial populations and regions may be most cost-effectively served by decentralized electricity. - Highlights: ► Centralized and decentralized electrification are compared for 150 countries. ► A cost-optimized network algorithm finds the least-cost electrification system. ► Least-cost infrastructures combine centralized and decentralized portions. ► For most people, centralized electricity is cheapest option. ► In much of Africa, decentralized electricity may be cheaper than centralized.

  7. The impacts of health, education, family planning and electrification programs on fertility, mortality and child schooling in East Java, Indonesia.

    This paper examines the effects of public health, family planning, education, electrification, and water supply programs on fertility, child mortality, and school enrollment decisions of rural households in East Java, Indonesia. The theoretical model assumes that parents maximize a utility function, subject to 1) a budget constraint that equates income with expenditures on children (including schooling and health inputs), and 2) a production function that relates health inputs to child survival possibilities. Public programs affect prices of contraceptives, schooling and health inputs, and environmental conditions that in turn affect child survival. Data are taken from the 1980 East Java Population Survey, the Socio-economic Survey, and the Detailed Village Census. The final sample consists of 3170 rural households with married women of childbearing age. Ordinary least squares and logit regressions of recent fertility, child mortality, and school enrollment on program and household variables yielded the following findings. 1) The presence of maternal and child health clinics reduced fertility but not mortality. 2) The presence of public health centers strongly reduced mortality but not fertility. 3) The presence of contraceptive distribution centers had no effect on fertility. 4) School attendance rates were influenced positively by the availability of primary and secondary schools. 5) Health and family planning programs had no effects on schooling. 6) The availability of public latrines reduced fertility and mortality. 7) The water supply variable did not affect the dependent variables when ordinary least squares techniques were applied but had statistically significant impact when logit methods were used. 8) Electricity supply had little effect on the dependent variables. 9) The mother's schooling had a strong positive correlation with children's schooling but no effect on fertility or mortality. 10) Household expenditures were related positively to school

    Solar home systems (SHSs) are a promising electrification option for many households in the developing world. In most countries SHSs are at an early stage of dissemination, and thus face a hurdle common to many emerging alternative energy technologies: many people do not know enough about them to decide whether to adopt one or not. This study uses survey data collected in Nicaragua to investigate characteristics that predict the knowledge and adoption of SHSs among the rural population. First, a series of probit models is used to model the determinants of four measures of SHS knowledge. Next, a biprobit model with sample selection is employed to investigate the factors that predict SHS adoption, conditional on having sufficient knowledge to make an adoption decision. Comparison of the biprobit formulation to a standard probit model of adoption affirms its value. This study identifies multiple determinants of SHS knowledge and adoption, offers several practical recommendations to project planners, and provides an analytical framework for future work in this policy-relevant area. - Research highlights: → Solar home systems (SHSs) are a promising rural electrification option in the developing world. → As with many emerging renewable energy technologies, lack of knowledge may limit SHS adoption. → We use probit models to investigate the determinants of SHS knowledge in rural Nicaragua. → We also employ a biprobit model linking the determinants of knowledge and adoption. → We find that in analyzing SHS adoption, accounting for sample selection based on knowledge is key.

    Electricity is essential for rural development. In 2005, 1.6 billion people, around a quarter of the world's population, living mostly in rural areas of developing countries, had no access to electricity. In general, remote rural areas in developing countries have little prospect of having access to grid-based electricity, which usually only extends to densely populated urban areas, where a large customer base justifies heavy expenditure for electricity infrastructure. One option for electrification in remote rural areas is to decentralize electricity systems based on renewable energy sources. However, such an option is not universally agreed upon. This dissertation examines a renewable energy-based rural electrification program, the 'Township Electrification Program', launched by the Chinese government in 2002. The Program was implemented in 1013 non-electrified townships in remote rural areas of 11 western provinces, providing electricity for 300,000 households and 1.3 million people. And at the time of research, the Program was known as the world's largest renewable energy-based rural electrification program in terms of investment volume ever carried out by a country. Two townships, Saierlong Township in Qinghai Province and Namcuo Township in Tibet Autonomous Region, were selected as cases for an in-depth examination of rural electrification practices in remote rural areas of western China. Both qualitative (interviews, observations, mapping, and transition walk) and quantitative (household survey) methods were applied in the field to collect data. The main findings of the study are summarized as follows: First, political leaders' concern over the unequal economic development of eastern and western China, as well as rural and urban areas, was the main factor triggering inclusion of the policy issue, electricity access in remote rural areas of western China, in the government's policy agenda. Second, like other energy policies, the formulation and adoption of

    A diagnostic study was carried out to evaluate the techno-economic viability of various electric supply sources for electrification of rural areas in Pakistan in present socio-economic conditions. The important influencing factors considered were: social needs, electric requirement and availability of energy resources. The electric requirements of model rural village were established at 20431 kw h per year. Prudent evaluations reveal that hydroelectric, photovoltaic and diesel systems are better options than an electric grid extension of more than 2 km. In order to become an economically meritorious energy source, photovoltaic system should attain cost level Rs. 100 per watt-peak of installed system. (author)

    Highlights: ► First disaggregated solar atlas of Djibouti from satellite data. ► Supply energy to remote populations by using solar systems requires planning. ► Assessment of the O and SI SAF SSI satellite-based radiation model accuracy. ► Implementation of a DEM-based disaggregation methodology. ► Establishment of a solar radiation atlas for Djibouti energy management. - Abstract: Nowadays, energy supply of rural populations is one of the most important challenges in African developing countries, and more particularly in Sub-Saharan Africa. With only one third of the population connected to the grid and the high economical and environmental cost of classical energy resources, the use of renewable energies within the rural energy supply pattern is a reliable alternative solution to improve human development of remote populations. Djibouti is a little poor country of Sub-Saharan Africa which perfectly symbolizes this way of life. Electrification rate is only about 30% and the important scattering of rural peoples throughout the country makes grid extension and fuel transportation unsuitable economic solutions to carry energy. The geographically diffused solar resource can therefore be an interesting mean to produce energy where it is consumed. The aim of this study was the creation of the first Djibouti’s global horizontal irradiation atlas, including assessment and improvement. To realize this atlas, a satellite-derived irradiance model was used (EUMETSAT O and SI SAF). To validate this model over Djibouti, we installed two temporary weather stations during the year 2010 in Djibouti-city and Dikhil and we compared hourly, daily and monthly irradiation estimates against ground-based measurements. Results showed a good agreement between measures and estimates, with a maximum Relative Root Mean Squared Error (RRMSE) over the hourly solar atlas of 12.43% and 15.44%, for Dikhil and Djibouti-city respectively. In order to improve geographic information and

    Full Text Available We explored the role of the water vapor content below the freezing level in the response of idealized supercell storm electrical processes to increased concentrations of cloud condensation nuclei (CCN. Using the Weather Research and Forecasting model coupled with parameterizations electrification and discharging, we performed 30 simulations by varying both the CCN concentration and water vapor content below the freezing level. The sensitivity simulations showed a distinct response to increased concentrations of CCN, depending on the water vapor content below the freezing level. Enhancing CCN concentrations increased electrification processes of thunderstorms and produced a new negative charge region above the main positive charge center when there were ample amounts of water vapor below the freezing level. Conversely, there were weak effects on electrification and the charge structure in numerical experiments initialized with lower water vapor content below the freezing level.

  16. Decarbonising the energy intensive basic materials industry through electrification – Implications for future EU electricity demand

    2016-01-01

    The need for deep decarbonisation in the energy intensive basic materials industry is increasingly recognised. In light of the vast future potential for renewable electricity the implications of electrifying the production of basic materials in the European Union is explored in a what-if thought-experiment. Production of steel, cement, glass, lime, petrochemicals, chlorine and ammonia required 125 TW-hours of electricity and 851 TW-hours of fossil fuels for energetic purposes and 671 TW-hours of fossil fuels as feedstock in 2010. The resulting carbon dioxide emissions were equivalent to 9% of total greenhouse gas emissions in EU28. A complete shift of the energy demand as well as the resource base of feedstocks to electricity would result in an electricity demand of 1713 TW-hours about 1200 TW-hours of which would be for producing hydrogen and hydrocarbons for feedstock and energy purposes. With increased material efficiency and some share of bio-based materials and biofuels the electricity demand can be much lower. Our analysis suggest that electrification of basic materials production is technically possible but could have major implications on how the industry and the electric systems interact. It also entails substantial changes in relative prices for electricity and hydrocarbon fuels. - Highlights: • Energy intensive basic materials industry has a high share in EU greenhouse gas emissions. • Decarbonising these industries is very important, but still relatively unexplored. • Electrification is possible regarding renewable energy resources and technologies. • Combination with energy and materials efficiency, biofuels and CCS is crucial. • Electrification needs very high amounts of electricity and strong policies.

    There have been significant advancements in electric vehicles (EVs) in recent years. However, the different changing patterns in emissions at upstream and on-road stages and complex atmospheric chemistry of pollutants lead to uncertainty in the air quality benefits from fleet electrification. This study considers the Yangtze River Delta (YRD) region in China to investigate whether EVs can improve future air quality. The Community Multiscale Air Quality model enhanced by the two-dimensional volatility basis set module is applied to simulate the temporally, spatially, and chemically resolved changes in PM 2.5 concentrations and the changes of other pollutants from fleet electrification. A probable scenario (Scenario EV1) with 20% of private light-duty passenger vehicles and 80% of commercial passenger vehicles (e.g., taxis and buses) electrified can reduce average PM 2.5 concentrations by 0.4 to 1.1 μg m -3 during four representative months for all urban areas of YRD in 2030. The seasonal distinctions of the air quality impacts with respect to concentration reductions in key aerosol components are also identified. For example, the PM 2.5 reduction in January is mainly attributed to the nitrate reduction, whereas the secondary organic aerosol reduction is another essential contributor in August. EVs can also effectively assist in mitigating NO 2 concentrations, which would gain greater reductions for traffic-dense urban areas (e.g., Shanghai). This paper reveals that the fleet electrification in the YRD region could generally play a positive role in improving regional and urban air quality.

    Rural Electrification Cooperatives (REC) has already played a fundamental role in rural electrification process. Bearing in mind changes in legislation towards specific laws that tend to facilitate energy distribution and trade relations, REC has increased there potential to contribute even more to above mentioned process. The present work intended to assess how REC settled in Parana State have adapted themselves to the privatised electrical business scenario as well as to new legal requirements and the presence of great national and international corporations disputing the energy market. Such new electrical market model favors huge changes to the electrification cooperatives, with the possibility of transforming cooperatives into public service energy with governmental permission. Moreover, it also represents a giant challenge for their insertion and continuity in such new scenario, in as much as the REC classification process as public service companies for electric energy distribution has been carried out for years, added to the scarcity of investments on state cooperatives, therefore restricting electric energy supply to residential, rural and irrigation sectors.

    interacting with the injector tube have been seen to become electrified with a relatively narrow range of surface charge concentration of around Q/4πr2 ~ −100 e-/µm2 (~ −0.02mC/m2) for all particle sizes. Several combinations of aerosol particle and injector tube composition were also investigated, some...... experiments (mC/m2). Possible explanations for this effect are discussed, including the possibility of field emission at the contact site. In the future this technique is intended also to be applied to particle-particle induced contact electrification and its material dependence....

    Mechanical brakes are often used by electric trains. These brakes have a few problems like response speed, coefficient of friction, maintenance cost and so on. As a result, methods for actively using regenerative brakes are required. In this paper, we propose the useful pure electric braking, which would involve ordinary brakes by only regenerative brakes without any mechanical brakes at high speed. Benefits of our proposal include a DC-electrification system with regenerative substations that can return powers to the commercial power system and a train that can use the full regenerative braking force. We furthermore evaluate the effects on running time and energies saved by regenerative substations in the proposed method.

    The effect of contact deformation on contact electrification of metallic materials was studied by the first-principles method. The results of charge population and the densities of states of the deformed contact models demonstrated that the magnitude of the transferred charge increased with deformation. The mechanism of the effect of deformation was investigated by studying the electronic properties of the deformed surface slabs. The results showed that crystal deformation led to a change in the electrostatic potential of the metal, where the number of nearly free electrons and unoccupied orbitals for charge transfer increased, and their energy barrier decreased.

  3. Solarising tropical Africa’s rural homes to sustainably overcome energy poverty

    2017-11-01

    At less than 30% electrification, Tropical Africa is the most energy-poor electrified region of the world. At home level, the annual per-capita electric energy consumption ranges between 0 and 150 kWh in rural areas, where 83% of the population reside. This is well below the 250 kWh recommended by the International Energy Agency (IEA) as the threshold for exiting rural ‘Energy Poverty’. Some governments have tried to extend the grid to such areas but these efforts have not yielded much. The approaches of rural electrification - as is being done now have therefore failed - and they may not be able to electrify every home in the countries concerned. An alternative approach promoting stand-alone photovoltaic (PV) and other solar powered heat and mass transfer systems at home level is proposed. An example of the approach in a village home in rural Uganda, East Africa is given. It is estimated that the combined unit energy cost over the systems’ lifespan would be just about US 3 cents. Health, Education, and Sustainability in all its forms would be greatly improved. The main recommendation is for policy makers to adopt this approach for rural homes while sparing grid supply only for commercial and industrial activities.

    Despite frequent blackouts and brownouts, extension of the central grid remains the Indian government's preferred strategy for the country's rural electrification policy. This study reports an assessment that compares grid extension with distributed generation (DG) alternatives, based on the subsidies they will necessitate, and costs of service interruptions that are appropriate in the rural Indian context. Using cross-sectional household expenditure data and region fixed-effects models, average household demand is estimated. The price elasticity of demand is found to be in the range of −0.3 to −0.4. Interruption costs are estimated based on the loss of consumer surplus due to reduced consumption of electric lighting energy that results from intermittent power supply. Different grid reliability scenarios are simulated. Despite the inclusion of interruption costs, standalone DG does not appear to be competitive with grid extension at distances of less than 17 km. However, backing up unreliable grid service with local DG plants is attractive when reliability is very poor, even in previously electrified villages. Introduction of energy efficient lighting changes these economics, and the threshold for acceptable grid unreliability significantly reduces. A variety of polices to promote accelerated deployment and the wider adoption of improved end-use efficiency, warrant serious consideration. - Highlights: • We question the reliance on conventional grid in rural electricity supply in India. • Alternatives compared through government subsidies and consumer interruption costs. • Interruption costs are estimated based on loss of consumer surplus due to outages. • Augmenting unreliable grid with local biomass or diesel based backups preferable. • With efficient lighting, standalone biomass plants are optimal at very low distances

    The objective of this paper objective is to show the policy and economics Bolivian rural electrification across the pilot plan named Inti K'anchay, using promotion of meetings among the agents; development of a credit structure and the concept of self-electrification; and reduction of differential costs. As a result of the Pilot plan 500 new systems have been installed, of which 446 have been installed by private companies. Environmental impacts have been reduced, as a consequence, though the substitution of diesel, candles and LPG. One conclusion is the fact that the organization of the user communities has been useful for the phases of identification, promotion and initial installation, notwithstanding the fact that, as time goes by and the installation becomes more familiar, the operation of the systems and management of the loans, for instance, tend to turn into individual chores rather than group activities.

    The lack of rural nursing studies makes it impossible to know whether rural and urban nurses perceive personal and organizational factors of job satisfaction similarly. Few reports of rural nurse job satisfaction are available. Since the unprecedented shortage of qualified rural nurses requires a greater understanding of what factors are important to retention, studies are needed. An analysis of the literature indicates job satisfaction is studied as both an independent and dependent variable. In this study, the concept is used to examine the intention to remain employed by measuring individual and organizational characteristics; thus, job satisfaction is used as a dependent variable. One hundred and three rural hospital nurses, from hospitals throughout the Northwest region of the United States were recruited for the study. Only nurses employed for more than one year were accepted. The sample completed surveys online. The McCloskey/Mueller Satisfaction Scale, the Gerber Control Over Practice Scale, and two open-ended job satisfaction questions were completed. The qualitative analysis of the open-ended questions identified themes which were then used to support the quantitative findings. Overall alphas were 0.89 for the McCloskey/Mueller Scale and 0.96 for the Gerber Control Over Practice Scale. Rural nurses indicate a preference for rural lifestyles and the incorporation of rural values in organizational practices. Nurses preferred the generalist role with its job variability, and patient variety. Most participants intended to remain employed. The majority of nurses planning to leave employment were unmarried, without children at home, and stated no preference for a rural lifestyle. The least overall satisfied nurses in the sample were employed from 1 to 3 years. Several new findings inform the literature while others support previous workforce studies. Data suggest some job satisfaction elements can be altered by addressing organizational characteristics and by

    Full Text Available In recent years, electrified transportation, be it in the form of buses, trains, or cars have become an emerging form of mobility. Electric vehicles (EVs, especially, are set to expand the amount of electric miles driven and energy consumed. Nevertheless, the question remains as to whether EVs will be technically feasible within infrastructure systems. Fundamentally, EVs interact with three interconnected systems: the (physical transportation system, the electric power grid, and their supporting information systems. Coupling of the two physical systems essentially forms a nexus, the transportation-electricity nexus (TEN. This paper presents a hybrid dynamic system assessment methodology for multi-modal transportation-electrification. At its core, it utilizes a mathematical model which consists of a marked Petri-net model superimposed on the continuous time microscopic traffic dynamics and the electrical state evolution. The methodology consists of four steps: (1 establish the TEN structure; (2 establish the TEN behavior; (3 establish the TEN Intelligent Transportation-Energy System (ITES decision-making; and (4 assess the TEN performance. In the presentation of the methodology, the Symmetrica test case is used throughout as an illustrative example. Consequently, values for several measures of performance are provided. This methodology is presented generically and may be used to assess the effects of transportation-electrification in any city or area; opening up possibilities for many future studies.

  8. Let There Be Light: the Role of Electrification in Liberia's Post-Conflict Stabilization

    Early in 2006, President Ellen Johnson-Sirleaf made re-electrification a cornerstone of Liberia's stabilization and redevelopment programs. After 14 years of civil war, there was no electric grid or commercial electricity in the country. The Liberia Electricity Corporation (LEC) was moribund, with no infrastructure or customers. An international donors group of Ghana, the EC, the World Bank, and USAID formulated a $7 million Emergency Power Program to restore power to parts of Monrovia. In four months, this group, with the active participation of GOL and LEC, imported generators, rebuilt distribution networks, and began commercial service. By the end of 2006, LEC was serving 280 customers and had achieved operational self-sufficiency. There were streetlights in the capital for the first time in years. A second phase, increasing generation and customers 5-fold, is underway. It is funded at $22 million by a donor group including Norway. At its conclusion, 70% of Monrovia's neighborhoods will have access to service. International private financing of a next phase is in the offing. Critical lessons offered: Electrification is central to post-conflict stabilization; Capacity development is as important as technology; Commercialization of electricity is required; and, Top level support is critical.

    The purpose of this study is to reveal relations between access to electricity and advancement in a socio-economic condition in rural areas of developing countries. Recently, multi-dimensional aspects of poverty, for example, economy, education, and health, has been increasingly focused on, and access to modern energy such as electricity is one possible solution. As a case study, we have analyzed unelectrified rural areas in Assam state, India. We have developed an energy-economic model in order to analyze the possibility of electrification through dissemination of electric lighting appliances as well as applied multiple regression analysis to estimate the socio-economic condition, a literacy rate above 6 years old, in the areas. As a result of the case study, the household electrification rate, the 1000 km{sup 2} road density, and sex ratio have been chosen as the explanatory variables of the literacy rate. Moreover, the model analysis shows that complete household electrification will be achieved by the year 2012. In combination with the multiple regression and model analysis, the literacy rate in Assam may increase to 74.4% from 63.3%. (author)

    Drivetrain electrification is an important frontline theme for automakers and automotive suppliers. It has already made inroads into mass production in the shape of start-stop systems. By contrast, the volumes of full hybrids are still small among most automakers; the first electric cars from the major automakers are now entering series production. Whereas the focus in the initial projects was still on attaining the necessary technical maturity, the issue of cost will increasingly take center stage in future. Variant management will also become more important in light of the wide range of vehicle topologies and technical solutions, as more and more model ranges are electrified: Modular systems and standardized interfaces are key elements in meeting cost targets. Simply optimizing individual components is not enough in this respect. The search for optimum solutions must start right from system level, describes Bosch. (orig.)

    2013-01-01

    We use a newly developed bottom-up model of the entire Canadian energy system (TIMES-Canada) to assess potentials for electrification of the road transport sector. A special emphasis has been put on the modelling of the Canadian road transport, by considering a variety of vehicles for passenger and freight transportation. Besides a business-as-usual (baseline) scenario, we have analysed an energy policy scenario imposing targets for electric vehicle penetration and a climate policy scenario imposing targets for greenhouse gas emission reduction. Our analysis shows on the one hand that electric vehicles penetrate notably the passenger vehicle market after 2040 in the baseline scenario and after 2030 in the energy policy scenario (following the assumed penetration targets). On the other hand, the assumed climate policy forces a stronger penetration of electric vehicles for passenger transportation, with a progressive phasing out of internal combustion engine vehicles, whereas the latter vehicles remain dominant for freight transportation but with a shift away of fossil fuels and in favour of biofuels. A sensitivity analysis on the (assumed) evolution of electric vehicles over time confirms these general trends. -- Highlights: •We use a newly developed TIMES-Canada model of the entire Canadian energy system. •We assess potentials for electrification of the Canadian road transport sector. •We analyse three scenarios: baseline, energy policy and climate policy. •EVs penetrate notably after 2040 in the baseline and after 2030 in the energy policy scenario. •The climate policy forces a stronger penetration of EVs

    This study followed the workforce choices of 10-years of graduates from a longitudinal rural immersion programme, which involved living for one academic year in a rural location as a medical student. The Rural Clinical School of Western Australia is a whole-of-state Rural Clinical School partnership involving two medical schools and fourteen rural/remote towns. For this longitudinal cohort study, all consenting graduates were contacted annually after graduation, with the outcome measure being rural work location (defined by the Australian Standard Geographical Classification -Remoteness Area) of any duration. There were 417 consenting graduates. Between 16 and 50% of contacted alumni worked rurally for a period of each post-graduate year. Aggregated over time, the majority took up to 30% of their postgraduate training rurally. There was considerable movement in and out of rural work. About 17% of contacted and practicing graduates were working full time rurally at the 2013 contact point. The majority remained in their state of training. The majority identified with GP and other rural-related colleges, and College-affiliation predicted amount of rural training time. Entry into rural work was equivalent for urban-origin and rural origin alumni, suggesting one year of RCS is sufficient to convert commitment to rural work. Undergraduate rural immersion is sufficient to create a graduate rural workforce that is far more mobile that was previously appreciated.

  17. Induction stoves as an option for clean cooking in rural India

    2016-01-01

    As part of a programme on ‘access to clean cooking alternatives in rural India’, induction stoves were introduced in nearly 4000 rural households in Himachal Pradesh, one of the few highly electrified states in India. Analysis of primary usage information from 1000 rural households revealed that electricity majorly replaced Liquid Petroleum Gas (LPG), generally used as a secondary cooking fuel, but did not influence a similar shift from traditional mud stoves as the primary cooking technology. Likewise, the shift from firewood to electricity as a primary cooking fuel was observed in only 5% of the households studied. Country level analysis indicates that rural households falling in lower monthly per capita expenditure (MPCE) classes have lesser access to electricity and clean cooking options than those falling in higher MPCE classes. Again, only three states in India with high levels of rural household electrification report consumption statuses more than 82 kWh per month (the estimated mean for electricity consumption by induction stoves). Overall, the results of the study indicate that induction stoves will have limited potential in reducing the consumption of firewood and LPG if included in energy access programmes, that too only in regions where high levels of electrification exist. - Highlights: • Primary survey of induction stove users was conducted in 1000 rural households. • In 84% households, electricity replaced LPG as the secondary cooking fuel. • In only 5% households, electricity replaced firewood as the primary cooking fuel. • Electricity as a cooking fuel for rural India still needs massive investments. • Currently, induction stoves are only able to reduce consumption of firewood and LPG.

    The Centers for Medicare & Medicaid Services (CMS) has facilitated the development of Medicare accountable care organizations (ACOs), mostly through the Medicare Shared Savings Program (MSSP). To inform the operation of the Center for Medicare & Medicaid Innovation's (CMMI) ACO programs, we assess the financial performance of rural ACOs based on different levels of rural presence. We used the 2014 performance data for Medicare ACOs to examine the financial performance of rural ACOs with different levels of rural presence: exclusively rural, mostly rural, and mixed rural/metropolitan. Of the ACOs reporting performance data, we identified 97 ACOs with a measurable rural presence. We found that successful rural ACO financial performance is associated with the ACO's organizational type (eg, physician-based) and that 8 of the 11 rural ACOs participating in the Advanced Payment Program (APP) garnered savings for Medicare. Unlike previous work, we did not find an association between ACO size or experience and rural ACO financial performance. Our findings suggest that rural ACO financial success is likely associated with factors unique to rural environments. Given the emphasis CMS has placed on rural ACO development, further research to identify these factors is warranted. © 2016 National Rural Health Association.

    This paper deals with design of hybrid energy system consisting of wind and photovoltaic with battery storage. A diesel generator is added to ensure continuous power supply and to take care of intermittent nature of wind and photovoltaic. The paper reports results of the technical-economic optimization study of photovoltaic/wind/diesel hybrid with battery storage in Algeria. The primary objective of this study is to estimate the appropriate dimension of stand-alone hybrid photovoltaic/wind/diesel with battery storage that guarantee the energy autonomy of typical remote consumer with lowest cost of energy. A secondary aim is to study the impact of renewable energy potential quality on the system size. The optimum dimensions of the system are defined for six sites in Algeria. In this context, a complete sizing model is developed in Matlab/Simulink V.6.5, able to predict the optimum system configuration. The simulation results indicate that the hybrid system is the best option for all the sites considered in this study. Thus, it provides higher system performance than photovoltaic or wind alone. It s shown that the principal advantage of photovoltaic/wind/diesel hybrid with battery storage are used all together, the reliability of the system is enhanced. The economic analysis has resulted in the calculation of kWh cost of energy for different types of resources and optimized cost of hybrid energy system. It s revealed too that the energy cost depends largely on the renewable energy potential quality. So, our objective for the optimization parameters is not the production cost but the offered service.

  2. Rural electrification, climate change, and local economies: Facilitating communication in development policy and practice on Nicaragua's Atlantic Coast

    Science.gov (United States)

    Casillas, Christian E.

    I explore the role of information and communication in the world of institution-led development. Through a series of case studies from the Atlantic Coast of Nicaragua, I present several projects and their implications for uncovering information that may lead to greater local benefit from externally-planned development projects. In order to construct policies and implement projects, development institutions collect, analyze, and simplify information, collapsing messy physical and social realities into narrow sets of metrics. In addition, local stakeholders often aren't privy to the analysis and assumptions of the "expert" planners. An evolved set of methods for dialogue and planning, which focus on sharing available information, can help facilitate outcomes that are more beneficial for targeted groups. Carbon abatement cost curves provide a clear example where the relations of complex social, economic, and environmental systems are reduced to a narrow set of metrics, specifically the cost of carbon mitigation and the total tons reduced. When the carbon abatement cost curve is applied to the community level, it reveals information and allows for conclusions obscured by aggregated national level studies. I show that there are opportunities for augmenting the limited metrics of these cost curves to include those that relate to welfare, beginning to highlight how costs and savings are distributed among stakeholders. In particular, the benefits to the most marginalized groups are heavily dependent on planners taking a pro-poor approach. However, planners typically remain blind to the priorities, capabilities, and values of the target stakeholders. There is a dearth of methods that effectively open up the development expert's black box of project designs, allowing their proposed solutions to be transparent to the target beneficiaries. I address this challenge through the presentation of a participatory modeling process that was utilized with groups of artisanal fishers. Participatory modeling places a greater emphasis on understanding processes, rather than just focusing on outcomes. The process facilitated the detailed exploration of local realities through the creation and playing of a board game that modeled their local fishing economy. Participants were able to look closely at the causal relations between several potential development interventions such as a cooperative-owned fish businesses and local ice production, gaining insights into possible costs and benefits.

    Indonesia is currently encouraging its physical, social and economy development. Physical development for economic development have to be supported by energy availability. For Indonesia, 90% of electrification ratio is still become an important task that has to be completed by the Government. However, the effort to increase electrification can become an environmental problem if it’s done with BAU scenario. The by-product of electric generation is the GHG, which increasing every year since 2006 from various sectors i.e. industry, housing, commercial, transportation, and energy. Net Zero Energy Building (NZEB) is an energy efficient building which can produce energy independently from clean and renewable sources. The energy that is generated by NZEB can be used for the building itself, and can be exported to the central grid. The integration of NZEB and Smart Grid can solve today’s issue on electrification ratio. Literature study will find benchmarks which can be applied in Indonesia along with possible obstacles in applying this technology.

    With 1.2 billion people still lacking electricity access by 2013, electricity access remains a major global challenge. Although mini-grid based electrification has received attention in recent times, their full exploitation requires policy support covering a range of areas. Distilling the experience from a five year research project, OASYS South Asia, this paper presents the summary of research findings and shares the experience from four demonstration activities. It suggests that cost-effective universal electricity service remains a challenge and reaching the universal electrification target by 2030 will remain a challenge for the less developed countries. The financial, organisational and governance weaknesses hinder successful implementation of projects in many countries. The paper then provides 10 policy recommendations to promote mini-grids as a complementary route to grid extension to promote electricity access for successful outcomes. - Highlights: •The academic and action research activities undertaken through OASYS South Asia Project are reported. •Evidence produced through a multi-dimensional participatory framework supplemented by four demonstration projects. •Funding and regulatory challenges militate against universal electrification objectives by 2030. •Innovative business approaches linking local mini-grids and livelihood opportunities exist. •Enabling policies are suggested to exploit such options.

    The purpose of this paper is to weigh the issues and options for increasing electricity access in remote and geographically challenged villages in interior Rajasthan, the desert state in Western India where power sector reforms are currently underway.

    Lafaille, Julien [BC Hydro (Canada)

    2011-07-01

    The paper presents the Remote Community Electrification (RCE) program and wind integration in BC's off grid communities. The program offers electric utility service to eligible remote communities in BC. Most of them are offered off-grid services although it is cheaper to connect a community to a grid. BC hydro serves some communities that are not connected to the main grid. Local diesel or small hydro-generating stations are used to serve remote communities. The renewable energy program target is to reach 50% of remote communities. The reason that wind is a small part of the renewables is that hydro and biomass are abundant in BC. Some other barriers include high installation costs, durability concerns, and lack of in-house technical expertise. Some small Wind initiatives that have been taken were relatively few and fairly small. It can be concluded that due to a poor wind resource and the relatively low cost of diesel, there is limited potential for wind in BC remote communities.

    Even vehicles of the generation still have significant potential to increase the efficiency of the powertrain, the auxiliaries and the electrical system. Good examples are the advancement of the start/stop system, which enables a higher recuperation of braking energy, and the recovery of waste heat from the combustion engine. This contribution shows a methodology to identify the potentials in real vehicles through measurements and simulations both at system and component level. Technical solutions for powertrain electrification and overall energy management found with this methodology are presented. The focus of the innovation and development process is on technical solutions, which may have only a mean potential for CO{sub 2} reduction, but have high cost efficiency. Such cost-effective technologies enable a broad market penetration and the opportunity for the systematic combination in the vehicle, and thus making a significant positive influence on the CO{sub 2} fleet balance and conservation of resources. Finally it is demonstrated how the optimization of the powertrain efficiency, the electrical system and the auxiliaries can contribute to the technology development for future vehicle concepts such as electric vehicles.

    2011-04-01

    This study investigated the physical processes involved in the development of thunderstorms over southwestern Amazon by hypothesizing causalities for the observed cloud-to-ground lightning variability and the local environmental characteristics. Southwestern Amazon experiences every year a large variety of environmental factors, such as the gradual increase in atmospheric moisture, extremely high pollution due to biomass burning, and intense deforestation, which directly affects cloud development by differential surface energy partition. In the end of the dry period it was observed higher percentages of positive cloud-to-ground (+CG) lightning due to a relative increase in +CG dominated thunderstorms (positive thunderstorms). Positive (negative) thunderstorms initiated preferentially over deforested (forest) areas with higher (lower) cloud base heights, shallower (deeper) warm cloud depths, and higher (lower) convective potential available energy. These features characterized the positive (negative) thunderstorms as deeper (relatively shallower) clouds, stronger (relatively weaker) updrafts with enhanced (decreased) mixed and cold vertically integrated liquid. No significant difference between thunderstorms (negative and positive) and nonthunderstorms were observed in terms of atmospheric pollution, once the atmosphere was overwhelmed by pollution leading to an updraft-limited regime. However, in the wet season both negative and positive thunderstorms occurred during periods of relatively higher aerosol concentration and differentiated size distributions, suggesting an aerosol-limited regime where cloud electrification could be dependent on the aerosol concentration to suppress the warm and enhance the ice phase. The suggested causalities are consistent with the invoked hypotheses, but they are not observed facts; they are just hypotheses based on plausible physical mechanisms.

    The electrode configuration of an electrostatic inkjet printing head is under study. This paper introduces the development of a new electrostatic inkjet head with an improved electrode configuration as compared to the conventional configuration. Two tungsten electrodes, connected in parallel, are inserted into the electrostatic print head at a certain angle from opposite sides. The aim of this double-side inserted angular electrodes (DSIAEs) head is to intensify the electrification of the fluid inside the head at minimum suitable exposure of the electrode, which results in maximizing surface charge density. The main advantage of the DSIAEs head is to get a very stable meniscus at low applied voltage for printing. This stable meniscus is transformed to a very stable jet by increasing the applied voltage. Therefore, printed patterns obtained with this DSIAEs head are more uniform because of a more stable meniscus and jet as compared to a conventional electrostatic vertically inserted single electrode head. Also, with this DSIAEs configuration, the life of the electrostatic inkjet printing head is increased.

  13. Assessment of the Electrification of the Road Transport Sector on Net System Emissions

    Science.gov (United States)

    Miller, James

    As worldwide environmental consciousness grows, electric vehicles (EVs) are becoming more common and despite the incredible potential for emissions reduction, the net emissions of the power system supply side plus the transportation system are dependent on the generation matrix. Current EV charging patterns tend to correspond directly with the peak consumption hours and have the potential to increase demand sharply allowing for only a small penetration of Electric Vehicles. Using the National Household Travel Survey (NHTS) data a model is created for vehicle travel patterns using trip chaining. Charging schemes are modeled to include uncontrolled residential, uncontrolled residential/industrial charging, optimized charging and optimized charging with vehicle to grid discharging. A charging profile is then determined based upon the assumption that electric vehicles would directly replace a percentage of standard petroleum-fueled vehicles in a known system. Using the generation profile for the specified region, a unit commitment model is created to establish not only the generation dispatch, but also the net CO2 profile for variable EV penetrations and charging profiles. This model is then used to assess the impact of the electrification of the road transport sector on the system net emissions.

    Electric vehicles can contribute to climate change mitigation if coupled with decarbonized electricity, but only if vehicle range matches travellers’ needs. Evaluating electric vehicle range against a population’s needs is challenging because detailed driving behaviour must be taken into account. Here we develop a model to combine information from coarse-grained but expansive travel surveys with high-resolution GPS data to estimate the energy requirements of personal vehicle trips across the US. We find that the energy requirements of 87% of vehicle-days could be met by an existing, affordable electric vehicle. This percentage is markedly similar across diverse cities, even when per capita gasoline consumption differs significantly. We also find that for the highest-energy days, other vehicle technologies are likely to be needed even as batteries improve and charging infrastructure expands. Car sharing or other means to serve this small number of high-energy days could play an important role in the electrification and decarbonization of transportation.

  15. Previously unknown species of Aspergillus.

    The use of multi-locus DNA sequence analysis has led to the description of previously unknown 'cryptic' Aspergillus species, whereas classical morphology-based identification of Aspergillus remains limited to the section or species-complex level. The current literature highlights two main features concerning these 'cryptic' Aspergillus species. First, the prevalence of such species in clinical samples is relatively high compared with emergent filamentous fungal taxa such as Mucorales, Scedosporium or Fusarium. Second, it is clearly important to identify these species in the clinical laboratory because of the high frequency of antifungal drug-resistant isolates of such Aspergillus species. Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) has recently been shown to enable the identification of filamentous fungi with an accuracy similar to that of DNA sequence-based methods. As MALDI-TOF MS is well suited to the routine clinical laboratory workflow, it facilitates the identification of these 'cryptic' Aspergillus species at the routine mycology bench. The rapid establishment of enhanced filamentous fungi identification facilities will lead to a better understanding of the epidemiology and clinical importance of these emerging Aspergillus species. Based on routine MALDI-TOF MS-based identification results, we provide original insights into the key interpretation issues of a positive Aspergillus culture from a clinical sample. Which ubiquitous species that are frequently isolated from air samples are rarely involved in human invasive disease? Can both the species and the type of biological sample indicate Aspergillus carriage, colonization or infection in a patient? Highly accurate routine filamentous fungi identification is central to enhance the understanding of these previously unknown Aspergillus species, with a vital impact on further improved patient care.

    Cuba's Guantanamo province is a leader in the application of renewable energy technologies. This paper discussed the socio-economic impact of renewable energy projects that are underway in the Guantanamo province to improve the standard of living in rural areas. More than 400 rural schools and 70 rural medical offices get their electricity from photovoltaic systems. Hydropower provides the energy needs to 3000 rural houses with 11,000 inhabitants. Other applications include remote community solar systems, improved woodstoves for community kitchens, solar cookers and solar dryers. This paper demonstrated how the high penetration of these renewable energy technologies has contributed to the sustainable development of the province. The lessons learned in energy management by the local governments and research institutions were also outlined. 1 tab.

    Availability of electricity can be used as an indicator to proximate parameters related to human well-being. Overall, the electrification process in Indonesia has been accelerating in the past two decades. Unfortunately, monitoring the country's progress on its effort to provide wider access to electricity poses challenges due to inconsistency of data provided by each national bureau, and limited availability of information. This study attempts to provide a reliable measure by employing nighttime satellite imagery to observe and to map the progress of electrification within a duration of 20 years, from 1993 to 2013. Brightness of 67,021 settlement-size points in 1993, 2003, and 2013 was assessed using data from DMSP/OLS instruments to study the electrification progress in the three service regions (Sumatera, Java-Bali, and East Indonesia) of the country's public electricity company, PLN. Observation of all service areas shows that the increase in brightness, which correspond with higher electricity development and consumption, has positive correlation with both population density (R 2  = 0.70) and urban change (R 2  = 0.79). Moreover, urban change has a stronger correlation with brightness, which is probably due to the high energy consumption in urban area per capita. This study also found that the brightness in Java-Bali region is very dominant, while the brightness in other areas has been lagging during the period of analysis. The slow development of electricity infrastructure, particularly in major parts of East Indonesia region, affects the low economic growth in some areas and formed vicious cycle.

  19. Rural-urban migration and socioeconomic development in Ghana: some discussions.

    1995-01-01

    This article presents a discussion of rural-urban migration as a source of social and behavioral change in Ghana. It explores the extent to which the urban social environment in Ghana generates conflicts for migrants with a different value orientation and the degree of influence of the urban social environment on migrants' behavior. The first part of the discussion focuses on the nature of Ghana's urbanization process, the motivation and characteristics of rural-urban migrants, and the nature of the social interaction between migrants and the social urban environment. Migrants contribute directly and indirectly to rural development in many ways. Some urban migrants achieve economic and material wealth and, through their attachment to voluntary tribal associations, assist local community development. Government can augment this process of migrant investment in rural life by identifying these actions as patriotic efforts and awarding citizenship medals or challenge grants. Governments need to review their citizenship laws carefully in light of the "brain drain" issues in the new world order and maximize the flow of resources, technical skills, and ideas from international migrants. A high-quality rural labor force can be enticed to live in rural areas by offering higher salaries and benefits, low income tax rates, better housing, and rural electrification and sanitation. Private firms should be offered incentives to locate in rural areas and increase employment opportunities for rural labor. Career advancement of development planners should be tied to program success or some form of public accountability for careful allocation of resources in rural areas. Fertility policies should be sensitive to urban subgroups. Urban and rural social differences are minor and do not impede urban assimilation, but unemployment and underemployment are problems for many.

    The sustainability of standalone photovoltaic systems passes through an accompaniment of the systems installed in the field. To subsidize this accompaniment it had been developed procedures for monitoring a similar system in laboratory. The standalone photovoltaic system monitored is similar to the systems installed by Companhia Energetica de Minas Gerais - CEMIG in the schools of isolated communities, inside the Solar Light Program. The system was simulated and the aims were to optimize the project and carry out a comparative study with the monitored results. The assembly procedure of the facility consisted of the implantation of the sensors, installation of acquisition boards and development of the monitoring program. The results presented here will allow the development of a program of preventive maintenance of the systems installed by CEMIG. (Author)

  2. Multi-Range Conditional Random Field for Classifying Railway Electrification System Objects Using Mobile Laser Scanning Data

    2016-12-01

    Full Text Available Railways have been used as one of the most crucial means of transportation in public mobility and economic development. For safe railway operation, the electrification system in the railway infrastructure, which supplies electric power to trains, is an essential facility for stable train operation. Due to its important role, the electrification system needs to be rigorously and regularly inspected and managed. This paper presents a supervised learning method to classify Mobile Laser Scanning (MLS data into ten target classes representing overhead wires, movable brackets and poles, which are key objects in the electrification system. In general, the layout of the railway electrification system shows strong spatial regularity relations among object classes. The proposed classifier is developed based on Conditional Random Field (CRF, which characterizes not only labeling homogeneity at short range, but also the layout compatibility between different object classes at long range in the probabilistic graphical model. This multi-range CRF model consists of a unary term and three pairwise contextual terms. In order to gain computational efficiency, MLS point clouds are converted into a set of line segments to which the labeling process is applied. Support Vector Machine (SVM is used as a local classifier considering only node features for producing the unary potentials of the CRF model. As the short-range pairwise contextual term, the Potts model is applied to enforce a local smoothness in the short-range graph; while long-range pairwise potentials are designed to enhance the spatial regularities of both horizontal and vertical layouts among railway objects. We formulate two long-range pairwise potentials as the log posterior probability obtained by the naive Bayes classifier. The directional layout compatibilities are characterized in probability look-up tables, which represent the co-occurrence rate of spatial relations in the horizontal and vertical

    2012-01-01

    As a potential poverty reduction and climate change strategy, this paper considers the advantages and disadvantages of using renewable energy technologies for rural electrification in developing countries. Although each case must be considered independently, given a reliable fuel source, renewable energy mini-grids powered by biomass gasifiers or micro-hydro plants appear to be the favoured option due to their lower levelised costs, provision of AC power, potential to provide a 24 h service and ability to host larger capacity systems that can power a wide range of electricity uses. Sustainability indicators are applied to three case studies in order to explore the extent to which sustainable welfare benefits can be created by renewable energy mini-grids. Policy work should focus on raising awareness about renewable energy mini-grids, improving institutional, technical and regulatory frameworks and developing innovative financing mechanisms to encourage private sector investments. Establishing joint technology and community engagement training centres should also be encouraged. - Highlights: ► Renewable mini-grids are a valuable climate change and poverty reduction strategy. ► They can be cheaper than diesel on a levelized basis and offer grid level service. ► Awareness about mini-grids should be raised and institutional frameworks improved. ► Financing mechanisms should be developed to encourage private sector investments. ► Joint technology and community engagement training centres should be established.

    2010-02-15

    In this paper, the rural electrification study of an ICT Telecenter in particular reference to the Kelabit Highland of Sarawak is presented. The use of diesel generator and its associated environmental implications is first discussed. The cost-effectiveness of the present solar PV system and the solar/hydro schemes for rural electrification of the rural ICT are evaluated employing the HOMER simulation software, considering sustainability factors such as system efficiency, weather, fuel costs, operating and maintaining costs. Subsequently, simple novel Hybrid Energy Performance Equations and the associated Energy Performance Curves are derived and introduced, respectively, which provide a visualization model, simplifying hybrid system analysis. Results obtained in this study have shown that combined power schemes is more sustainable in terms of supplying electricity to the Telecenter compared to a stand-alone PV system due to prolong cloudy and dense haze periods. The hybrid systems can have efficiency range of {proportional_to}15%-75% compared to PV stand-alone of only {proportional_to}10%, indicating hybrid systems are more reliable and sustainable - in minimizing both energy losses and excess energy.

    1996-12-31

    This paper discusses issues related to rural electrification in China, with emphasis on a pilot project in Mongolia to implement small scale renewable energy sources. These projects consist of photovoltaic systems, wind electric systems, photovoltaic/wind hybrid systems, and wind/gasoline generator sets. These systems are small enough to implement in rural environments, more cost effective than grid type systems, and have lower cost than standard generator sets alone because of the improved reliability. The author also discusses the use of such systems for village power sources. A number of factors are contributing to the increase in such systems. Individuals are able and willing to pay for such systems, lending institutions are willing to fund such small-scale projects, they provide reliable, high quality services which support social and economic development.

    2007-07-01

    Early in 2006, President Ellen Johnson-Sirleaf made re-electrification a cornerstone of Liberia's stabilization and redevelopment programs. After 14 years of civil war, there was no electric grid or commercial electricity in the country. The Liberia Electricity Corporation (LEC) was moribund, with no infrastructure or customers. An international donors group of Ghana, the EC, the World Bank, and USAID formulated a $7 million Emergency Power Program to restore power to parts of Monrovia. In four months, this group, with the active participation of GOL and LEC, imported generators, rebuilt distribution networks, and began commercial service. By the end of 2006, LEC was serving 280 customers and had achieved operational self-sufficiency. There were streetlights in the capital for the first time in years. A second phase, increasing generation and customers 5-fold, is underway. It is funded at $22 million by a donor group including Norway. At its conclusion, 70% of Monrovia's neighborhoods will have access to service. International private financing of a next phase is in the offing. Critical lessons offered: Electrification is central to post-conflict stabilization; Capacity development is as important as technology; Commercialization of electricity is required; and, Top level support is critical.

  9. Electrification of particulate entrained fluid flows-Mechanisms, applications, and numerical methodology

    2015-10-01

    Particulates in natural and industrial flows have two basic forms: liquid (droplet) and solid (particle). Droplets would be charged in the presence of the applied electric field (e.g. electrospray). Similar to the droplet charging, particles can also be charged under the external electric field (e.g. electrostatic precipitator), while in the absence of external electric field, tribo-electrostatic charging is almost unavoidable in gas-solid two-phase flows due to the consecutive particle contacts (e.g. electrostatic in fluidized bed or wind-blown sand). The particle charging may be beneficial, or detrimental. Although electrostatics in particulate entrained fluid flow systems have been so widely used and concerned, the mechanisms of particulate charging are still lack of a thorough understanding. The motivation of this review is to explore a clear understanding of particulate charging and movement of charged particulate in two-phase flows, by summarizing the electrification mechanisms, physical models of particulate charging, and methods of charging/charged particulate entrained fluid flow simulations. Two effective methods can make droplets charged in industrial applications: corona charging and induction charging. The droplet charge to mass ratio by corona charging is more than induction discharge. The particle charging through collisions could be attributed to electron transfer, ion transfer, material transfer, and/or aqueous ion shift on particle surfaces. The charges on charged particulate surface can be measured, nevertheless, the charging process in nature or industry is difficult to monitor. The simulation method might build a bridge of investigating from the charging process to finally charged state on particulate surface in particulate entrained fluid flows. The methodology combining the interface tracking under the action of the applied electric with the fluid flow governing equations is applicable to the study of electrohydrodynamics problems.

    Here we apply the cell tracking methodology, shown in our companion poster, to quantifying factors affecting the vigor and the time-height evolution of hydrometeors and electrification properties of convective cells. Benefitting from the Dual-polarimetric NEXRAD radar network, we composite more than 5000 well-tracked cells among three radars (at Houston, Lubbock and Oklahoma City), stratified by CCN, CAPE and land/sea locations. The analyzed cell properties include Z, ZDR, Kdp, and ρhv, Dm (raindrop diameter) and Nw (raindrop concentration) by the algorithm of Bringi et al. (2003). Lightning Mapping Array (LMA) data is also included in the analysis, which provides a 3D structure of lightning occurrence and RF power. The contrasting CCN conditions over marine, land, pristine and polluted areas are identified based on the satellite retrieval technique described in Rosenfeld et al. (2016). The results show that more CCN are associated with: Increased echo top height, manifesting the invigoration effect. Enhanced reflectivities, especially above the freezing level at around 4.5 km. Raindrop sizes at the initial stage increase at the expense of their concentrations, due to the smaller cloud droplets and suppressed coalescence. Larger propensity for hail. Lightning sources increase with greater CCN concentration and is likely due to the delayed warm rain process and enhanced mixed phase process under more CCN condition, when activated CCN into cloud droplets is too high (> 1000 cm-3) the glaciation is delayed too much and leave little ice at lower levels and thus decrease lightning activity. Land pristine clouds have fewer lightning sources than polluted clouds. Marine pristine clouds seldom have lightning Increased CAPE had a similar effect to the effect of added CCN. The cloud tracking and properties are obtained by a new methodology of Multi-Cell Identification and Tracking (MCIT) algorithm (Hu et al, 2017), with details about the algorithm to be found in the author

    1) How the project adds to the education of engineering students in the area of vehicle electrification: This project created and implemented a significant interdisciplinary curriculum in HEV engineering that includes courses focused on the major components (engines, battery cells, e-machines, and power electronics). The new curriculum, rather uniquely, features two new classes and two new labs that emphasize a vehicle level integration of a hybrid electric powertrain that parallels the vehicle development process used by the OEMs - commercial grade software is used to design a hybrid electric vehicle, hardware-in-the-loop testing is performed on each component until the entire powertrain is optimized, the calibration is flashed to a vehicle, ride-and-drives are executed including on board data acquisition. In addition, nine existing courses were modified by adding HEV material to the courses. 2) The educational effectiveness and economic feasibility of the new curriculum: The new courses are offered at both the undergraduate and graduate levels. They are listed across the college in mechanical, chemical, electrical, and materials science and engineering. They are offered both on campus and to distance learning students. Students across the college of engineering and at all degree levels are integrating these courses into their degree programs. Over the three year project the course enrollments on-campus has totaled 1,249. The distance learning enrollments has totaled 315. With such robust enrollments we absolutely expect that these courses will be in the curriculum for the long run. 3) How the project is otherwise of benefit to the public: One outcome of the project is the construction of the Michigan Tech Mobile Lab. Two complete HEV dynamometer test cells, and four work stations are installed in the 16.2 meter Mobile Laboratory and hauled by a class 8 truck. The Mobile Lab is used to teach the university courses. It is also used to deliver short courses to

    Energy planners in regions with low rates of electrification face complex and high-risk challenges in selecting appropriate generating technologies and grid centralization. To better inform such processes, we present an Agent-Based Model (ABM) that facilitates engagement with stakeholders. This approach evaluates long-term plans using the cost of delivered electricity, resource mix, jobs and economic stimulus created within communities, and decentralized generation mix of the system, with results provided in a spatially-resolved format. This approach complements existing electricity planning methods (e.g., Integrated Resource Planning) by offering novel evaluation criteria based on typical stakeholder preferences. We demonstrate the utility of this approach with a case study based on a “blank-slate” scenario, which begins without generation or transmission infrastructure, for the long-term rural renewable energy plans of Liberia, West Africa. We consider five electrification strategies: prioritizing larger populations, deploying large resources, creating jobs, providing economic stimulus, and step-wise cost minimization. Through the case study we demonstrate how this approach can be used to engage stakeholders, supplement more established energy planning tools, and illustrate the effects of stakeholder decisions and preferences on the performance of the system. - Highlights: • An Agent Based Model, BABSTER, for electrification planning is presented. • BABSTER provides a highly engaging spatially resolved interface. • Allows flexible investigation of decision strategies with real-world incentives. • We show that decision strategies directly impact centralization and resource choice. • It is illustrated through the case study of Liberia, West Africa.

    A majority of the rural population in India continues to rely on kerosene for domestic lighting. Measures to promote inter-fuel substitution in domestic lighting by promoting rural electrification have met with partial success. Electrified households in rural areas also use kerosene as a back up fuel because of erratic and poor electricity supply. Kerosene is subsidised, and an extensive network has been put in place for its distribution. Both these measures are meant to facilitate access and affordability by the poor. However, this is not the case at the grass-roots level. Further, use of traditional lighting devices has also had an adverse affect on the quality of life of the people for these devices are inefficient, emit smoke, and give poor-quality light. In this the poorest of the poor, who have limited choices and options are worst affected. This paper, taking the example of a TERI (the Energy and Resources Institute) case study in the state of Rajasthan, analyses the issues of access and availability of kerosene to rural masses, especially the poor. It highlights the existing problems with the kerosene distribution system and examines the subsidy-based, supply driven approach to distribution in terms of facilitating access to the poor. It, accordingly, puts forward specific policy measures for improving access to kerosene and its more efficient use as a lighting fuel in rural India

    With more than one billion people lacking access to electricity in the world, ensuring universal access to electricity by 2030 remains a major challenge which cannot be left to the government initiatives alone. Access to local information and identification of potential areas for investment can be a challenge for investors. This paper provides a tool for preliminary assessment of potential markets for off-grid electrification in developing countries and applies this to Ghana to demonstrate its applicability. A multi-criteria approach is used to rank the districts according to the overall potential and the best markets and least favourable areas for investment are identified. The tool offers flexibility to include new inputs to the analysis and the factor weights can be adjusted as appropriate. The case study shows that the tool can effectively identify potential areas from a list of candidates and offers support to analysts.

    Access to energy is known as a key issue for poverty reduction. Electrification rate of sub-Saharan countries is one of the lowest among the developing countries. However, this part of the world has natural energy resources that could help raising its access to energy, then its economic development. An original 'flexy-energy' concept of hybrid solar PV/diesel/biofuel power plant, without battery storage, is performed in this paper. This concept is developed in order to not only make access to energy possible for rural and peri-urban populations in Africa (by reducing the electricity generation cost) but also to make the electricity production sustainable in these areas. For landlocked countries like Burkina Faso, this concept could help them reducing their electricity bill (then their fuel consumption) and accelerate their rural and peri-urban electrification coverage. - Research highlights: → Design and load management Optimization are big concerns for hybrid systems. → Hybrid solar PV/Diesel is economically viable for remote areas and environmental friendly. → 'Flexy-energy' concept is a flexible hybrid solar PV/diesel/biomass suitable for remote areas. → 'Flexy-energy' concept is a flexible hybrid solar PV/diesel/biomass suitable for remote areas.

    2013-01-01

    Debates on the nexus between energy and development emphasise that access to modern energy carriers such as electricity improve development outcomes. This paper discusses the impacts of electrification on educational outcomes, gender and power relations, income generation, feelings of inclusion and exclusion and health in the village of Tsilitwa in the rural Eastern Cape, South Africa. It is based on an ethnographic grounded theory study conducted in 2009. The paper shows that the impacts of electricity may not match the benefits cited in the literature, and are not experienced in the same way by everyone in the community. The study uncovers the weakness of ignoring individual and group agency, and the complexity of social settings when advocating interventions to improve quality of life. The paper recommends that researchers and policymakers consider using ethnographic methods to complement other methods and reveal context and its implications on the energy–development nexus that other methods may not capture. - Highlights: • Linkages between energy and development outcomes are complex and not deterministic. • Ethnography better reveals the complex relationship between energy and development. • People's contexts affect whether, how and who benefits from energy access. • Benefits like sense of worth and inclusion are often neglected in development. • Electrification can have negative impacts such as rising sense of income disparity

    2013-01-01

    Energy resources for rural electrification are variable and widely dispersed, such that a solution for one region might not be appropriate for another. This study evaluates the feasibility of renewable energy technologies, centralized grid extension and local coal-fired power for rural areas that currently do not have sufficient access to electricity. The renewable power generation options considered are solar photovoltaic and wind power, with battery storage or fossil fuel generator backup. New local coal-fired power, as well as extension of the grid from an existing centralized power system, are considered to compare the impacts of scale and traditional approaches to power generation. A case study for a rural area in Northwestern China demonstrates the complexity of energy decision-making when faced with low peak demands and non-ideal renewable resource availability. Economic factors, including cost of electricity generation, breakeven grid extension distance, capacity shortage fraction (the ratio of the annual capacity shortage to the annual electric load) and land use are evaluated. - Highlights: • Considerations include technical and non-technical factors for energy decisions. • Coal and renewable power are compared based on cost and availability of resources. • Key factors for renewable power generation are capacity shortage and availability of resources. • Rural China case study evaluates the viability of distributed wind or solar power relative to coal

    This paper discusses the central importance of energy inputs in development, and presents the complex interactions within subsystems that contribute a Rural Energy System. This paper also brings about the importance of the primary data for realistic renewable energy planning at the micro level in a given rural system. Factors that render secondary data somewhat inadequate for such applications are discussed. The differences between energy related data from secondary and primary sources in respect of representative villages in Kanyakumari District of Tamil Nadu, India, are detailed. A rural system model for computing the output from various components of a rural system is also presented. This projection is made by making use of a set of technical coefficients, which relate the inputs to the outputs from individual segments of the rural production system. While some of the technical coefficients are developed based on previously published data, a large number have been quantified on the basis of careful survey. The usefulness of the model is discussed. The paper also presents a Linear Programming Model for optimum resource allocation in a rural system. The objective function of the Linear Programming Model is maximizing the revenue of the rural system where in optimum resource allocation is made subject to a number of energy and non-energy related relevant constraints. The model also quantifies the major yields as well as the byproducts of different sectors of the rural economic system. (Author)

    To study the impact of geomagnetic storm on the equipment of traction electrification system in the high-speed railway, geomagnetically induced current (GIC) monitoring devices were installed in the Hebi East traction power supply substation of the Beijing-Hong Kong Dedicated Passenger Line in January 2015, and GICs were captured during the two geomagnetic storms on 17 March and 23 June 2015. In order to investigate the GIC flow path, both in the track circuit and in the traction network adopting the autotransformer feeding system, a GIC monitor plan was proposed for the electrical system in the Hebi East traction power supply substation. This paper analyzes the correlation between the GIC captured on 17 March and the geomagnetic data obtained from the Malingshan Geomagnetic Observatory and presents a regression analysis between the measured GIC and the calculated geoelectric fields on 23 June in the high-speed railway. The maximum GICs measured in the track circuit are 1.08 A and 1.74 A during the two geomagnetic storms. We find that it is necessary to pay attention on the throttle transformers and track circuits, as the most sensitive elements responding to the extreme geomagnetic storms in the high-speed railway.

Retrospective cohort analysis of computerized laboratory data (complete blood count, sodium, potassium, and creatinine levels, prothrombin time, and partial thromboplastin time). Urban tertiary care Veterans Affairs Hospital. Consecutive sample of 1109 patients who had elective surgery in 1988. At admission, 7549 preoperative tests were done, 47% of which duplicated tests performed in the previous year. Of 3096 previous results that were normal as defined by hospital reference range and done closest to the time of but before admission (median interval, 2 months), 13 (0.4%; 95% CI, 0.2% to 0.7%), repeat values were outside a range considered acceptable for surgery. Most of the abnormalities were predictable from the patient's history, and most were not noted in the medical record. Of 461 previous tests that were abnormal, 78 (17%; CI, 13% to 20%) repeat values at admission were outside a range considered acceptable for surgery (P less than 0.001, frequency of clinically important abnormalities of patients with normal previous results with those with abnormal previous results). Physicians evaluating patients preoperatively could safely substitute the previous test results analyzed in this study for preoperative screening tests if the previous tests are normal and no obvious indication for retesting is present.

    Mistry, Ritesh; Galal, Osman; Lu, Michael

    2009-09-01

    Studies in low-income countries have shown that women's autonomy (i.e. the freedom of women to exercise their judgment in order to act for their own interests) influences a number of reproductive and child health outcomes, including the use of pregnancy care services. However, studies have not examined the full spectrum of pregnancy care services needed for safe motherhood and have not accounted for community context. This study analyzed data on women and their villages from the cross-sectional population-based National Family Health Survey-2 (1998-1999) of rural India to investigate whether women's autonomy (measured in the 3 dimensions of decision-making autonomy, permission to go out, and financial autonomy) was associated with the use of adequate prenatal, delivery and postnatal care. The findings indicate women's autonomy was associated with greater use of pregnancy care services, particularly prenatal and postnatal care. The effect of women's autonomy on pregnancy care use varied according to the region of India examined (North, East and South) such that it was most consistently associated with pregnancy care use in south India, which also had the highest level of self-reported women's autonomy. The results regarding village level factors suggest that public investment in rural economic development, primary health care access, social cohesion and basic infrastructure such as electrification and paved roads were associated with pregnancy care use. Improvements in women's autonomy and these village factors may improve healthier child bearing in rural India.

    2017-07-01

    This paper presents the analysis of potential wind speed of electrical power generating using for agriculture in Ratchaburi province, Thailand. The total area is 1,900 square kilometers. First of all, the agriculture electrical load (AEL) data was investigated from all farming districts in Ratchaburi. Subsequently, the load data was analyzed and classified by the load power and energy consumption at individual district. The wind turbine generator (WTG) at capacity rate of 200w, 500w, 1,000w, and 2,000w were adopted to implement for the AEL in each area at wind speed range of 3 to 6 m/s. This paper shows the approach based on the wind speed at individual district to determine the capacity of WTG using the capacitor factor (CF) and the cost of energy (COE) in baht per unit under different WTG value rates. Ten locations for wind station installations are practical investigated. Results show that for instance, the Damnoen Sa-duak (DN-04) one of WTG candidate site is identically significant for economic investment of installing rated WTG. The results of COE are important to determine whether a wind site is good or not.

    This paper presents the first experimental evidence of pronounced electrification effects upon reversible cycle of forced water intrusion-extrusion in nanoporous hydrophobic materials. Recorded generation of electricity combined with high-pressure calorimetric measurements improves the energy balance of {nanoporous solid + nonwetting liquid} systems by compensating mechanical and thermal energy hysteresis in the cycle. Revealed phenomena provide a novel way of "mechanical to electrical" and/or "thermal to electrical" energy transformation with unprecedented efficiency and additionally open a perspective to increase the efficiency of numerous energy applications based on such systems taking advantage of electricity generation during operational cycle.

    Social isolation in medical students is a subjective experience that may influence medical career decision making. Rural self-efficacy has been shown to influence rural career intentions following a rural clinical placement, however its impact on social isolation during a rural clinical placement has not been previously modeled. The objective of this study is to explore whether self-perception of social isolation is associated with rural career intent in rural medical students. Secondly, to determine whether self-efficacy influences the association between social isolation and rural career intent. 2015 data, from a cross-sectional survey of the National Federation of Rural Australian Medical Educators (FRAME) study. Among 619 medical students attending rural clinical schools (RCS), rural career intent was assessed. This included intended rural location for either postgraduate medical specialist or generalist training or completion of that training. Self-efficacy beliefs in rural medical practice were based on a validated scale consisting of six questions. Social isolation was measured asking students whether they felt socially isolated during their RCS placement. 31.3% of surveyed students self-reported feeling socially isolated during their rural placement. Social isolation was associated with reduced rural career intent after controlling for gender, rural background, RCS preference, RCS support and wellbeing. In step-wise logistic regression the association between social isolation and rural intent disappeared with the inclusion of rural self-efficacy. Social isolation during a rural clinical placement is commonly reported and is shown to reduce rural career intent. High levels of rural clinical self-efficacy reduce the effects of social isolation on future rural workforce intentions.

    The 'Luz do Campo' program has created positive and favorable impact to the opening of opportunities in the rural area. It has contributed to facilitate the access of workers to energetic facilities and has contributed to providing them with better social and economical conditions. As a consequence after the accomplishment of the rural electrification process in the settlements of 'Anhumas' and 'Maria Neto' implanted in Ribeirao Claro in Parana, it was possible to come to terms with two projects of Sericiculture in that location. The energy consumption of these projects has not been only restricted to human comfort, but has also been aimed at the production. As a result, the economical success achieved in those settlements in less than a year's time, is due to the transformation actions in the countryside that have lowered poverty and raised the perspectives of better life quality to the settlers.

    Nine percent of new mothers in the United States who participated in the Listening to Mothers II Postpartum Survey screened positive for meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for posttraumatic stress disorder after childbirth. Women who have had a traumatic birth experience report fewer subsequent children and a longer length of time before their second baby. Childbirth-related posttraumatic stress disorder impacts couples' physical relationship, communication, conflict, emotions, and bonding with their children. The purpose of this study was to describe the meaning of women's experiences of a subsequent childbirth after a previous traumatic birth. Phenomenology was the research design used. An international sample of 35 women participated in this Internet study. Women were asked, "Please describe in as much detail as you can remember your subsequent pregnancy, labor, and delivery following your previous traumatic birth." Colaizzi's phenomenological data analysis approach was used to analyze the stories of the 35 women. Data analysis yielded four themes: (a) riding the turbulent wave of panic during pregnancy; (b) strategizing: attempts to reclaim their body and complete the journey to motherhood; (c) bringing reverence to the birthing process and empowering women; and (d) still elusive: the longed-for healing birth experience. Subsequent childbirth after a previous birth trauma has the potential to either heal or retraumatize women. During pregnancy, women need permission and encouragement to grieve their prior traumatic births to help remove the burden of their invisible pain.

  5. Vehicle lightweighting vs. electrification: Life cycle energy and GHG emissions results for diverse powertrain vehicles

    Highlights: • We modeled life cycle energy and greenhouse gas (GHG) emissions from diverse powertrain vehicles. • Lightweight versions of the vehicle models were compared against baseline models. • Maximum energy and GHG emissions occur with aluminum vs. advanced high strength steel. • Design harmonization method shows 0.2–0.3 kg of support required per 1 kg powertrain mass increase. - Abstract: This work assesses the potential of electrified vehicles and mass reduction to reduce life cycle energy and greenhouse gas (GHG) emissions. Life cycle assessment (LCA) is used to account for processes upstream and downstream of the vehicle operation, thereby incorporating regional variation of energy and GHG emissions due to electricity production and distinct energy and GHG emissions due to conventional and lightweight materials. Design harmonization methods developed in previous work are applied to create baseline and lightweight vehicle models of an internal combustion vehicle (ICV), hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV). Thus, each vehicle is designed to be functionally equivalent and incorporate the structural support required for heavier powertrains. Lightweight vehicles are designed using body-in-white (BIW) mass reduction scenarios with aluminum and advanced/high strength steel (A/HSS). For the mass reduction scenarios considered in this work, results indicate that the greatest life cycle energy and GHG emissions reductions occur when steel is replaced by aluminum. However, since A/HSS requires less energy to produce as compared to aluminum, the energy and GHG reductions per unit mass removed is greatest for A/HSS. Results of the design harmonization modeling method show that 0.2–0.3 kg of structural support is required per unit increase in powertrain mass, thus extending previous methods

  6. Double jeopardy: The dichotomy of fuelwood use in rural South Africa

    2013-01-01

    Energy security is central to achieving sustainable development and reducing poverty worldwide. Over 70% of the population of Sub-Saharan Africa, mostly in the rural areas, depend on wood fuel, as firewood or charcoal, to meet their primary domestic energy requirements. This dependence is projected to increase with population growth in the intermediate future, regardless of the implementation of rural electrification programmes.. Fuelwood shortages occur at the localised village level and are a chronic landscape syndrome, becoming more severe over time, with increasing population pressures and competing land-uses. In the South African context, the provision of electricity to rural households at subsidised rates would be expected to provide a viable alternative to fuelwood under conditions of scarcity. This paper compares the fuelwood consumption strategies of households in a fuelwood-scarce environment against those in fuelwood-abundant environment in order to illustrate the inelastic nature of the demand for fuelwood in rural communities, even in the face of severely depleted wood stocks. We seek to understand the mechanisms that households implement to ensure household fuelwood/energy security and how these responses aggregate at the landscape level to shape landscape dynamics. This will aid better planning of intervention policies in the future. - Highlights: ► Rural household demand for fuelwood is inelastic inspite of fuelwood scarcity. ► Electricity is incorporated into household energy mix but is rarely used exclusively. ► Opportunity-cost of wood collection is discounted by the lack of viable alternatives. ► Potential for land-use conflicts once communal woodland resources are depleted.

  7. A Simple Approach to Characterize Gas-Aqueous Liquid Two-phase Flow Configuration Based on Discrete Solid-Liquid Contact Electrification.

    Choi, Dongwhi; Lee, Donghyeon; Kim, Dong Sung

    2015-10-14

    In this study, we first suggest a simple approach to characterize configuration of gas-aqueous liquid two-phase flow based on discrete solid-liquid contact electrification, which is a newly defined concept as a sequential process of solid-liquid contact and successive detachment of the contact liquid from the solid surface. This approach exhibits several advantages such as simple operation, precise measurement, and cost-effectiveness. By using electric potential that is spontaneously generated by discrete solid-liquid contact electrification, the configurations of the gas-aqueous liquid two-phase flow such as size of a gas slug and flow rate are precisely characterized. According to the experimental and numerical analyses on parameters that affect electric potential, gas slugs have been verified to behave similarly to point electric charges when the measuring point of the electric potential is far enough from the gas slug. In addition, the configuration of the gas-aqueous liquid two-phase microfluidic system with multiple gas slugs is also characterized by using the presented approach. For a proof-of-concept demonstration of using the proposed approach in a self-triggered sensor, a gas slug detector with a counter system is developed to show its practicality and applicability.

  11. The marginalization of "small is beautiful": Micro-hydroelectricity, common property, and the politics of rural electricity provision in Thailand

    Science.gov (United States)

    Greacen, Christopher Edmund

    This study analyzes forces that constrain sustainable deployment of cost-effective renewable energy in a developing country. By many economic and social measures, community micro-hydro is a superior electrification option for remote mountainous communities in Thailand. Yet despite a 20 year government program, only 59 projects were built and of these less than half remain operating. By comparison, the national grid has extended to over 69,000 villages. Based on microeconomic, engineering, social barriers, common pool resource, and political economic theories, this study investigates first, why so few micro-hydro projects were built, and second, why so few remain operating. Drawing on historical information, site visits, interviews, surveys, and data logging, this study shows that the marginal status of micro-hydro arises from multiple linked factors spanning from village experiences to geopolitical concerns. The dominance of the parastatal rural electrification utility, the PEA, and its singular focus on grid extension are crucial in explaining why so few projects were built. Buffered from financial consequences by domestic and international subsidies, grid expansion proceeded without consideration of alternatives. High costs borne by villagers for micro-hydro discouraged village choice. PEA remains catalytic in explaining why few systems remain operating: grid expansion plans favor villages with existing loads and most villages abandon micro-hydro generators when the grid arrives. Village experiences are fundamental: most projects suffer blackouts, brownouts, and equipment failures due to poor equipment and collective over-consumption. Over-consumption is linked to mismatch between tariffs and generator technical characteristics. Opportunities to resolve problems languished as limited state support focused on building projects and immediate repairs rather than fundamentals. Despite frustrations, many remain proud of "their power plant". Interconnecting and selling

    For the 20(th) century since the Depression, we find a strong correlation between a 'literary misery index' derived from English language books and a moving average of the previous decade of the annual U.S. economic misery index, which is the sum of inflation and unemployment rates. We find a peak in the goodness of fit at 11 years for the moving average. The fit between the two misery indices holds when using different techniques to measure the literary misery index, and this fit is significantly better than other possible correlations with different emotion indices. To check the robustness of the results, we also analysed books written in German language and obtained very similar correlations with the German economic misery index. The results suggest that millions of books published every year average the authors' shared economic experiences over the past decade.

  14. Explorations in Aeolian Ecology: Radar and Visual Studies of the Aerofauna during the Convection and Precipitation/electrification (cape) Experiment.

    Russell, Robert William

    I studied the ecology of aerial insects and birds (the "aerofauna") during the Convection and Precipitation/Electrification (CaPE) Experiment in Florida during the summer of 1991. Visual observations were coordinated with simultaneous measurements of atmospheric motions, permitting novel explorations of: (1) patterns and processes in the distribution of "aerial plankton" (i.e., small, weakly flying insects that drift with boundary-layer winds); (2) the feeding ecology of "aerial planktivores" (i.e., predators that feed on aerial plankton); and (3) the flight tactics of soaring birds. Sensitive Doppler radars regularly detected fine lines of enhanced reflectivity in boundary-layer convergence zones. These "fine lines" were attributable to dense concentrations of aerial plankton entrained by the convergent airflow. Insect densities were inferred to be about an order of magnitude higher inside convergence zones then elsewhere. Anecdotal observations suggested that large quantities of aerial plankton entrained in convergence zones were sometimes "scrubbed" from the boundary layer by precipitation. Radar images clearly depicted the rapid aeolian transport of aerial plankton across the landscape, but also showed that densities of aerial plankton became concentrated along coastlines when winds blew toward the sea. In contrast, airspace over the adjacent ocean remained largely free of radar echoes under all wind conditions. The coastal concentrations, together with the absence of overwater echoes, indicate that the organisms comprising the aerial plankton respond behaviorally to coastlines to avoid being blown out to sea. Several species of aerial insectivorous predators commonly exploited boundary-layer fine lines as food resources. Chimney swifts (Chaetura pelagica), barn swallows (Hirundo rustica), and wandering gliders (Pantala flavescens) showed significant responses to fine lines. Details of these responses differed, but this variation clearly reflected species

    INTRODUCTION We noted a report that more significant symptoms may be expressed after second whiplash injuries by a suggested cumulative effect, including degeneration. We wondered if patients were underestimating the severity of their earlier injury. PATIENTS AND METHODS We studied recent medicolegal reports, to assess subjects with a second whiplash injury. They had been asked whether their earlier injury was worse, the same or lesser in severity. RESULTS From the study cohort, 101 patients (87%) felt that they had fully recovered from their first injury and 15 (13%) had not. Seventy-six subjects considered their first injury of lesser severity, 24 worse and 16 the same. Of the 24 that felt the violence of their first accident was worse, only 8 had worse symptoms, and 16 felt their symptoms were mainly the same or less than their symptoms from their second injury. Statistical analysis of the data revealed that the proportion of those claiming a difference who said the previous injury was lesser was 76% (95% CI 66–84%). The observed proportion with a lesser injury was considerably higher than the 50% anticipated. CONCLUSIONS We feel that subjects may underestimate the severity of an earlier injury and associated symptoms. Reasons for this may include secondary gain rather than any proposed cumulative effect.

    Currently very popular in the market of tobacco products have gained electronic cigarettes (ang. E-cigarettes). These products are considered to be potentially less harmful in compared to traditional tobacco products. However, current reports indicate that the statements of the producers regarding to the composition of the e- liquids not always are sufficient, and consumers often do not have reliable information on the quality of the product used by them. This paper contain a review of previous reports on the composition of e-cigarettes and their impact on health. Most of the observed health effects was related to symptoms of the respiratory tract, mouth, throat, neurological complications and sensory organs. Particularly hazardous effects of the e-cigarettes were: pneumonia, congestive heart failure, confusion, convulsions, hypotension, aspiration pneumonia, face second-degree burns, blindness, chest pain and rapid heartbeat. In the literature there is no information relating to passive exposure by the aerosols released during e-cigarette smoking. Furthermore, the information regarding to the use of these products in the long term are not also available.

    Building rural energy infrastructure in developing countries remains a significant financial, policy and technological challenge. The growth of the electric vehicle (EV) industry will rapidly expand the resource of partially degraded, ‘retired’, but still usable batteries in 2016 and beyond. These batteries can become the storage hubs for community-scale grids in the developing world. We model the resource and performance potential and the technological and economic aspects of the utilization of retired EV batteries in rural and decentralized mini- and micro-grids. We develop and explore four economic scenarios across three battery chemistries to examine the impacts on transport and recycling logistics. We find that EVs sold through 2020 will produce 120-549 GWh in retired storage potential by 2028. Outlining two use scenarios for decentralized systems, we discuss the possible impacts on global electrification rates. We find that used EV batteries can provide a cost-effective and lower environmental impact alternative to existing lead-acid storage systems in these applications.

    2006-01-01

    Until recently, there has been a significant gap in the literature exploring the issues of the mental health needs for rural communities in Australia. In this study we investigated the prevalence of diagnosable psychological disorders in both a rural and a non-rural primary care sample in far north Queensland, Australia. In a previous study we had screened some 300 GP attendees, on a number of sociodemographic variables and measures of psychological wellbeing, from four rural GP practices and one regional GP practice. Of these, 130 participants agreed to further follow up. In this study, 118 of the participants were selected and contacted by phone to complete the Composite International Diagnostic Interview-Short Form (CIDI-SF). The CIDI-SF diagnosis was then analysed in relation to the sociodemographic indicators that had previously been collected. The prevalence of diagnosable mental health disorders in the rural sample was found to be higher in comparison with the regional urban sample. The sociodemographic factors of rural residence, gender, and length of residence were associated with having a CIDI-SF diagnosis. Although there were a number of methodological limitations to this study, there did appear to be a significant relationship between rural location and the likelihood of receiving a CIDI-SF diagnosis. Why this might be the case is not clear, and we consider a number of explanations, but our finding suggests that further research in mental health should consider the issue of rurality as a key feature to be explored.

  12. Static electrification testing of Texas Utilities 345-20.9 kV, 650 MVA generator step-up transformer under controlled factory conditions

    International Nuclear Information System (INIS)

    Crofts, D.W.; Moore, H.

    1995-01-01

    Comanche Peak Nuclear Power Plant, with two 1150 Megawatt units, has two 345-20.9 kV, three-phase, 650 MVA transformers connected in parallel. The transformers have had a long history of hydrogen generation, and one of the Unit No. 2 transformers failed in 1983 while energized from the system for plant construction power. The failed unit was repaired and returned to Comanche Peak, and there was no evidence of static electrification involvement in the failure. During the time from installation to commercial operation in 1990 for Unit No. 1 and 1992 for Unit No. 2, the transformers were backfed from the system as needed to provide construction power. There was little regard paid to the operation of the cooling systems other than assuring the cooling was running. The transformers on unit No. 1 were subjected to several unusual electrical events - ferroresonance in 1981 and over excitation in 1983, with the generation of gasses of great concern. The decision was made to install a new transformer and return the old unit to the factory for diagnostic testing to determine the cause for the generation of combustible gas, primarily hydrogen. The dielectric integrity of the transformer could be quantified and decisions made concerning the replacement of the remaining transformers. After testing, the transformer was disassembled for forensic evaluation and rebuilt for return as a spare or to replace another transformer while undergoing repairs. Deformation of the bottom of the tank was discovered with large dents in the bottom protruding inward approximately one and one-half inches. With the concern of decreased clearances or displaced flux shields in the tank, an inspection opening was cut in the end of the transformer near the bottom. While investigating the deformation, evidence of partial discharge activity was discovered at the bottom of the high-to-low insulation; a location where static electrification damage has been observed in other large shell-form transformers

  13. Performing rurality. But who?

    Directory of Open Access Journals (Sweden)

    Dymitrow Mirek

    2017-12-01

    Full Text Available Reflective inquiries to better understand ‘the rural’ have tried to embed rural research within the notion of performativity. Performativity assumes that the capacity of language is not simply to communicate but also to consummate action, whereupon citational uses of concepts produce a series of material effects. Of late, this philosophical shift has also implicated geographers as active agents in producing, reproducing and performing rurality. This paper provides a critical evaluation of what this new insistence really means for the production of geographical knowledge. Using framework analysis as a method, the paper scrutinizes several reportedly influential papers on the topic of rural performativity. Our findings reveal that, while indeed reflexive on issues of academic integrity, methodology and ethics, performances of rurality are continuedly placed ‘out there’ amongst ‘rural people’, i.e. in a priori defined and often stereotypically understood contexts, either by way of ‘spatial delimitation’ or ‘activity delimitation’. Effectively, such testimonies provide a truncated state of fidelity, where performance- oriented reflexivity is seconded by contradictory empirics of uneven value and with few commonalities. We conclude that by turning towards performativity as an allegedly more helpful way of obtaining rural coherence, we at the same time overlook our own role in keeping ‘rural theory’ alive.

    This paper considers the role of culture in rural health, suggesting that the concept and its impacts are insufficiently understood and studied. It reviews some of the ways that culture has been considered in (rural) health, and states that culture is either used ambiguously and broadly - for example, suggesting that there is a rural culture, or narrowly - indeed perhaps interchangeably with ethnicity, for example Aboriginal culture as a unity. The paper notes that, although culture is a dynamic social concept, it has been adopted into a biomedical research paradigm as though it is fixed. Culture is often treated as though it is something that can be addressed simplistically, for example, through cultural sensitivity education. Authors suggest that culture is an unaddressed 'elephant in the room' in rural health, and that exploring cultural differences and beliefs and facing up to cultural differences are vital in understanding and addressing rural health and health system challenges. © 2012 The Authors.
