O trabalho de pesquisa tem por objetivo estudar e oferecer uma nova política de eletrificação rural para o Estado de São Paulo, tendo por base o seguinte questionamento: cabe ao Estado de São Paulo manter política própria de eletrificação rural após a lei da universalização, nº 10.438/2002, do programa Luz para Todos e, ainda, do conjunto de Resoluções da ANEEL sobre o assunto? A abordagem do assunto tem por base a experiência do autor sobre o tema eletrificação rural, em especial com os programas desenvolvidos no Estado a partir de 1996, sob gestão ou coordenação da CERESP, órgão da Secretaria de Saneamento e Energia (SSE). A regulação da época previa que o interessado deveria pagar pelo custo de conexão à rede elétrica das concessionárias, assim, os programas desenvolvidos até então, tratavam de complexos sistemas de financiamento dessas conexões. As inovações desses programas contribuíram para a implantação da lei da universalização 10.438/2002 e do programa Luz para Todos. O programa Luz para Todos trata a universalização de modo diferente daquele determinado pela Resolução 456/2000, em que os benefícios concedidos aos interessados atendidos pelo programa são mais abrangentes daqueles permitidos pela regulação atual. A pesquisa mostra que esse é o diferencial que permite a real universalização do acesso ao serviço público de eletricidade no meio rural, de forma adequada. O programa será encerrado em dezembro de 2010, cabendo às concessionárias atender os interessados apenas pelos critérios da universalização. O trabalho aponta grande possibilidade de exclusão do acesso à eletricidade a partir desse momento, e propõe oferecer ao Estado uma pesquisa que indique caminhos que possibilite a São Paulo antecipar-se às consequências que virão com fim do Programa Luz para Todos. Trata-se, assim, de pesquisa que envolve experiência profissional e conhecimento acadêmico. / The research work aims to study and provide a new policy of rural electrification in the State of Sao Paulo, based on the following question: \"the State of Sao Paulo must maintain its own policy of rural electrification after the universal law, nº 10.438/2002, the Light for All program and also the set of resolutions by ANEEL on the matter?\" The approach to the subject is based on the author\'s experience on the subject of rural electrification, especially through programs developed in the state since 1996, under the management or coordination of CERESP, organ of the SSE. The regulation of time provided that the person should pay for the cost of grid connection to the utilities power grids, therefore the programs developed so far, dealt with complex financial systems of these connections. The innovations of these programs contributed to the implementation of the law universal nº 10438/2002 and the Light for All program. The Light for All Program is universal and so different from that determined by ANEEL Resolution 456/2000, where the benefits granted to persons enrolled in the program are the most comprehensive of those allowed by current regulation. Research shows that this is the differential that allows the real universal access to public electricity in rural areas, as appropriate. The program will end in December 2010, leaving it to dealers only meet the criteria of universality. The work shows great possibility of exclusion from access to electricity from that time, and proposes giving the state a survey indicating that enable paths to Sao Paulo to anticipate the consequences that come with the end of the Light for All Program. Therefore, it is a research that involves work experience and academic knowledge.

Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. By utilizing a renewable energy source, solar technology for the generation of electricity, photovoltaics (PV) is being considered as a way forward to minimize the environmental problems related to energy use. This thesis aims to contribute to improving the technical and social feasibility of PV and PV-diesel hybrid micro-grids for the purpose of providing access to electricity to people in rural areas of countries with low level access to electricity. In line with these general aims, the focus has been to address three questions related to challenges in three phases of rural electrification. The work has a multi-disciplinary approach, addressing mainly technical and social aspects of long-term sustainability of micro-grids, in a local context, and the changes these are intended to generate. One specific micro-grid in Tanzania has been used as a major case study. The thesis is developed through three papers, all presenting methodologies or aspects for investigation in rural electrification projects and studies in general, and for PV-diesel hybrid micro-grids in particular. Paper I puts forward a methodology to facilitate non-social scientific researchers to take social aspects increasingly into consideration. Paper II is a guideline to support system users to increasingly apply an evaluation based system operation. Paper III specifically highlights the importance to consider blackouts when investigating how an existing off-grid PV-diesel hybrid system shall be utilized when a national grid becomes available.

A partir do processo de implantação dos sistemas fotovoltaicos SIGFI 13 na comunidade do Varadouro, isolada na floresta tropical do litoral sul do Estado de São Paulo, este trabalho identificou e caracterizou os principais entraves para difusão e adoção dos mesmos, com vistas ao desenvolvimento local e à melhoria da qualidade de vida. A fundamentação se baseia em referências teóricas sobre temas como comunidades tradicionais, exclusão social, atendimento de serviços públicos, dificuldade de implementação de projetos em comunidades isoladas e no relato da prática de experiências semelhantes em outros países. O método utilizado para pesquisa na comunidade foi o estudo de caso, que constou de revisões bibliográficas sobre trabalhos na região, visitas a campo e entrevistas com atores que trabalham na área. Os dados coletados foram analisados em uma abordagem voltada a compreender: a existência de barreiras no processo de implementação dos sistemas; os aspectos a considerar na superação dessas barreiras; e fatores positivos resultantes da implementação de tecnologia nessa comunidade tradicional. Os novos sistemas mostraram-se importantes e capazes de gerar sentimento de inclusão. Alguns usuários reclamam de não poder usar geladeira, sem, contudo, perder interesse pelo sistema disponível. A principal barreira diz respeito à falta de capacidade de organização dos moradores em prol de um objetivo comum e coletivo. Para a comunidade se desenvolver, não basta o acesso à energia. É preciso que sejam supridas suas necessidades básicas, tais como, saneamento básico, educação, saúde, transporte e acesso à comunicação, que são responsabilidade de Estado. Esta pesquisa conclui que o processo social de eletrificação rural através de tecnologia fotovoltaica é uma iniciativa que trás inovações que precisam ser adotadas e socializadas, e sua difusão deve levar em consideração a vivência coletiva dos moradores de cada comunidade. / Starting from the implementation process of the SIGFI 13 photovoltaic systems in the community of Varadouro, isolated in the rain forest in the Southern coast of São Paulo State, the objective of this work was to identify and characterize the main barriers to extending and adopting these systems, aiming at local development and life quality improvement. Foundation is grounded on theoretical references about themes such as traditional communities, social exclusion, public service assistance, project implementation difficulties in isolated communities, and on reports about similar practices in other countries. The method used was that of study of case, which consisted of bibliographic reviews on works in the region, field visits, and interviews with the people involved who work in the area. The data collected were analyzed according to an approach aiming at understanding: the existence of obstacles in the process of system implementation; the aspects to be considered when overcoming these barriers; and the positive factors arisen from the technology implementation in this traditional community. The new systems showed to be important and capable of generating a feeling of inclusion. Some users complain about not being able to use a refrigerator, without losing interest in the available system, though. The main hurdle concerns the locals lack of organization skills in favor of a collective and joint objective. The community development requires more than the access to energy itself. Their basic needs, such as sanitation, education, health, transport and access to communication which are the States responsibility -, must be provided. This research has come to the conclusion that the social process of rural electrification by photovoltaic technology is an initiative that brings up innovations which must be adopted and socialized, and its extension should take into account the collective locals life experience of each community.

Com base nos dados do IBGE, estima-se que aproximadamente 2,4 milhões de domicílios brasileiros não têm acesso ao serviço de energia elétrica. Ainda, projeções da Aneel indicam que, após a alteração dos critérios determinados pela Lei nº 10.438/2002, o número de unidades consumidoras classificadas na subclasse residencial baixa renda passou de 8 para 14 milhões. Conforme estimativas atuais, são necessários recursos da ordem de R$ 7,3 bilhões para equacionar o acesso à energia elétrica daqueles domicílios, bem como de aproximadamente R$ 1 bilhão por ano para compensar as distribuidoras pela perda de receita decorrente do aumento do número de consumidores baixa renda. Os dois aspectos são complementares na conceituação da universalização, na visão do autor. Deste modo, este estudo apresenta uma visão sistêmica sobre ambos os aspectos da universalização: a garantia do acesso físico e do uso contínuo; sendo este último considerado como as condições para a manutenção do acesso ao serviço de eletricidade por meio de uma tarifa social ou de programas compensatórios. O objetivo principal dessa dissertação é, então, analisar e avaliar as normas legais e os regulamentos que norteiam as políticas públicas de universalização dos serviços de energia elétrica, como também dos que indiretamente interferem nessas ações, buscando identificar eventuais necessidades de sua complementação ou mesmo de sua alteração. Para isso, mostra-se a evolução recente das ações do Estado, da legislação pertinente e da regulamentação promovida pela Aneel para cada um das duas vertentes da universalização. Apresenta-se também a dimensão dos recursos financeiros envolvidos, identificando os possíveis impactos decorrente da nova regulamentação da subclasse residencial baixa renda e também do programa de universalização Luz para Todos. / IBGE data has shown that approximately 2.4 million Brazilian households do not have access to electricity service. Moreover, Aneel´s projections indicate that, after the alteration of the criteria determined by Law 10,438/2002, the number of households classified as low income residential subclass has increased from 8 to 14 million. Further studies imply that R$ 7.3 billion would be necessary to enable those 2.4 million households to have access to electric energy, as well as R$ 1 billion per year to compensate the utilities for the loss resulting from the increase of low income consuming domiciles. The two aspects are complementary as for the universal electricity service, in the vision of the author. Hence, this work proposes to overview both aspects: to ensure physical access and the continuous use through social tariffs or compensating programs. The main objective of this dissertation is to analyze and to evaluate the regulations which guide the public policies of universal electricity service in order to identify whenever its complementation or its alteration is required. Thus, this study shows relevant government policies and Aneel regulation as well as necessary resources, possible and likely impacts to improve the current situation.

Thesis (M. Dev.) -- University of Limpopo, 2002 / Refer to document

Thesis (M.DEV.) --University of Limpopo, 2012 / The main purpose of this study was to assess the role played by Polokwane Local Municipality in delivery of basic services such as water, sanitation, electricity , and housing in the village of Manthorwane, Limpopo Province. It was of critical importance for the researcher to investigate this area, as there was no study done before related to basic services delivery. The objectives of the study were ,to assess the extent to which the municipality is providing basic services, investigate the strength, weaknesses , examine the impact of the Municipality‘s role in the development of Manthorwane Village and recommending strategies for enhancing the level of basic service delivery. Qualitative and quantitative research methods were used because the study combines the use of instruments and methods for measurement and the way the researcher interacts with the people. Interviewees and questionnaires were used to understand the community’s feeling towards delivery of basic services. The researcher has gone through a detailed process of investigation, where it is found that there is no delivery of basic services (electricity, sanitation, housing). Only water has been provided in this village. The researcher also discovered that there are no valid reasons why the Polokwane Municipality has not delivered the services above. It is also revealed that there are no stakeholder’s participation and consultations meetings when the decisions for service delivery are taken. Evaluation and monitoring tools are not applied when implementing projects. There are some recommendations proposed to the municipality. The municipality could intensify their training process in a way in which the officials could be productive to the community. Transparency must always be practiced for the municipality to excel in their delivery services. Intergovernmental relationship is also encouraged. Awareness programs must be done effectively so that the community is aware of all activities done in their area.

The importance of access to modern energy has been well understood by governments and donor agencies in many developing countries, and significant effort has been made in recent years to address energy access challenges. However, despite these efforts, the International Energy Agency (IEA) has predicted that the energy access problem will remain unresolved by 2030. Therefore, adequate and appropriate action is needed to resolve this problem more quickly. This dissertation analyses policies and their impacts and will help researchers and policy makers in developing countries to (i) understand the impact of policies in the formation of a renewable energy (RE) market, (ii) consider the determinants of technological choices when promoting access to energy services and, (iii) better appreciate the sustainability performance of rural energy. For the purpose of analysis, several country cases from Asia and Sub-Saharan Africa region were carried out as these are the two main regions where the energy access problem are most acute. To understand the impact of policies in the formation of RE based rural electrification market, a case study was conducted in Nepal. The study has shown that rural electrification has been expanding as a consequence of market-oriented policies. When it comes to selection of electrification path-ways, different technological alternatives are analysed in Afghanistan and Nepal, taking levelized cost of electricity (LCOE) as the means to select cost effective options. The analysis has presented best-fit conditions for these various technological pathways in the two countries and verified whether they are following the appropriate and cost effective course in their efforts to expand rural electrification. For understanding the determinants of cooking fuel choices and to analyse policy implications in the transition of large populations from traditional to modern fuels, fuel choices are modelled in the case of China. Choices are modelled (using MESSAGE–ACCESS mod-el) with standard economic variables such as income, technology costs and fuel prices, along with some unique variable such as inconvenience costs. Future access scenarios are designed considering different policy options to accelerate the transition. Sustainability is one of the key concerns in terms of energy access. This dissertation introduces methods for evaluating (i) the sustainability performance of energy technologies and (ii) the status and progress of developing countries in providing sustainable energy access. Different sets of sustainability indicators are considered for the rural energy sector and aggregated to form a single composite index. The energy technology sustainability index (ETSI) is used for assessing the performance of different energy technological systems in the case of India. The analysis reveals that mature technologies such as biomass gasifiers, biogas and micro hydro have relatively better sustainability performance among the options considered, while solar and wind, though showing fairly good improvement in sustainability performance, still have difficulties competing with more mature and conventional technologies without policy support. The Energy Sustainability Index (ESI) has been applied to China, India, South Africa, Sri-Lanka, Bangladesh and Ghana between 1990 and 2010 to evaluate the status and progress made by these countries in rural energy sustainability. The analysis suggests that South Africa’s rural energy sustainability index is highest followed by China, Sri Lanka, India, Bangladesh and Ghana respectively. The rural energy sustainability has improved relatively over time in all countries except Ghana. The dissertation shows that policies are helping the rapid expansion of the RE market though with uneven penetration in rural Nepal. Access to credit and cumbersome subsidy delivery mechanism are perceived as the major factors affecting the expansion of rural electrification, requiring innovation. The electrification pathways taken by Nepal seem functional and moving in the right direction but some flaws in the delivery mechanisms require attention. Meanwhile in Afghanistan, pathways are not well defined and the country lacks a clear-cut national policy framework for the expansion of rural electrification. The analysis on fuel transition shows that even a fast developing country such as China will continue to have serious problems guaranteeing the access to solid fuels for cooking for one third of its rural population by 2030. The problem could be more severe in poorer nations. There-fore, further policy intervention addressing the high implicit discount rate of the poorer section of the population, reducing the upfront cost of more efficient technology (stoves) or the costs of cleaner fuels with subsidies must be considered to promote energy transition. Overall, this dissertation has analysed key issues in the global discussion about sustainable energy access. The methods for sustainability assessment suggested have been specially designed for rural settings in developing countries and are instrumental to assess the performance of rural energy technologies and track the progress of sustainable energy access efforts among rural households. / <p>QC 20140210</p>

Rural electrification is a critical tool for accelerating and enhancing development throughout Sub-Saharan Africa. The challenge for modern policymakers is to identify and implement programs that will effectively facilitate rural electrification. This analysis develops a model for comparing the performance of nations' electrification policies using a fixed effects regression model based on World Bank data from 1990, 2000 and 2010. To identify the key policies for driving rural electrification, this analysis then compares the programs and reforms employed in six nations from Sub-Saharan Africa. As a result, three reform measures are identified that are conditional on outside factors for their contribution to success, and three universal policies are identified that may be broadly applied to improve rural electrification throughout the region.
