Abstract
Rapid growth of distributed photovoltaics (DPV) has upended how engineers traditionally think about electric power systems. Consumers now increasingly generate their own power and feed it to the grid. Poorly managed DPV poses distinct risks for power systems as penetration increases. Yet, low- and middle-income countries can benefit from this clean distributed energy resource. How can DPV and power systems be planned and operated to mitigate risks and reap technical benefits This report, the second in a series of three, presents a menu of technical solutions applicable across diverse contexts. Balancing DPV supply with local loads, as far as practical, can help keep grid operations within technical limits. A grid’s hosting capacity for DPV can also be enhanced on multiple fronts to cope with changed conditions. Many solutions are inexpensive. Inverter programming unlocks valuable services. Anticipating challenges and opportunities can avoid costly fixes. All countries can benefit from a grid code and planning approach that reflect expected growth of distributed resources. Prudent technical criteria can be used to streamline new approvals for grid-friendly DPV. These measures also require the timely capacity building of personnel. This report is aimed mainly at a technical audience—planners, distribution and transmission grid operators, and expert staff of energy authorities. However, the report also aims to introduce the issues simply enough for non-technical readers to become familiar with them. Examples of standards are provided for readers seeking more details.

Publication From Sun to Roof to Grid(World Bank, Washington, DC, 2021-10-18)As the world’s fastest-growing local energy technology, distributed photovoltaics (DPV) has upended the traditional paradigm of one-way power flow from the grid to consumers. Solar electricity systems located close to grid consumers known here as DPV empower consumers to produce electricity for themselves and for the grid. Thanks mainly to falling PV costs, DPV has become a viable way to meet energy needs for a widening array of consumers. Worldwide, installed capacity of DPV exploded from just a few megawatts (MW) in 2000 to 250 gigawatts (GW) in 2019; and it is forecast to exceed 500 GW by 2025. Poorly managed, DPV scale-up can then erode utility finances and interfere with grid operation. Yet, as explained in this report, well-managed DPV can benefit not only DPV owners but also contribute to reliable grid operation and a financially sound electricity sector. DPV offers multiple types of benefits relevant for low- and middle-income countries, especially when it can reduce electricity costs and widespread dependence on diesel generators. This report is an overview of DPV in different country contexts, and it is aimed at energy ministries and other decision-makers. Chapter 1 introduces key concepts and the recent status of the DPV market. It also highlights key potential value propositions of DPV for different stakeholders, including consumers, utilities, governments, and society as a whole. Chapter 2 presents nine specific ways in which distributed photovoltaics (PV) is or could be used to solve problems faced in low and middle-income country contexts.Publication 2022 Mini Grids for Half a Billion People(Washington, DC: World Bank, 2022-09-22)This book is packed with actionable information for decision-makers, and it is the World Bank’s most comprehensive and authoritative publication on mini grids to date. The objective of this comprehensive knowledge package is to present road-tested options and examples from the leading edge of mini grid development. Decision-makers can draw on these options and examples to scale up mini grid deployment in their own contexts. By acknowledging different national approaches to mini grids and providing context-specific considerations for implementation, this suite of knowledge products offers an adaptive approach to helping countries achieve their electrification targets. The book is structured as follows. The overview presents a global market outlook for mini grids and introduces the 10 building blocks that need to be in place if mini grids are to be scaled up in any country. These building blocks also represent the 10 frontiers for innovation for the sector, where, with disruptive digital solutions across all 10 frontiers, the services offered to end users can be raised to a level substantially better than what would be possible with alternatives. In the Handbook, the terms “building blocks” and “frontiers” are used interchangeably. Chapters 1–10 present the 10 building blocks in detail and answer the question how do we scale up mini grid deployment to connect half a billion people by 2030 Chapter 11 is our call to action.Publication Honduras(World Bank, Washington, DC, 2010-05)This report was prepared in response to a request by the government of Honduras for assistance in the preparation of a power sector strategy for the country. Specifically, the government asked for help in identifying the main issues in the power sector, and in addressing them through formulation of a clearly defined, achievable strategy. Left unresolved, these issues risk derailing the country's macroeconomic framework, potentially damaging the competitiveness of the country and its prospects for poverty reduction. The main issues to be analyzed in the study were identified at a workshop held on September 19, 2006, in Tegucigalpa, jointly with the Secretaria de Recursos Naturales y Ambiente (SERNA) and the Comision Presidencial de Modernizacion del Estado (CPME), and with the participation of representatives from the Empresa Nacional de Energia Electrica (ENEE), civil society, the private sector, Congress, public sector agencies, donors, utilities, and ministries. It was decided that the study would be divided into two components: (a) the first would identify and evaluate options on institutional reforms, particularly ENEE's restructuring and management, and securing electricity supply; and (b) the second would formulate a power sector strategy. Two reports will be prepared, with the second report to be finalized according to the timing of the government's decision. This first report analyzes the institutional and policy issues; financial and fiscal concerns; social aspects, such as tariffs and subsidies, and access to electricity; and investment requirements including the development of renewable resources. The report is divided into two parts. Part A presents a diagnostic of the electricity sector, including ENEE's financial performance, fiscal impacts, and reliability of supply, institutional and legal framework, pricing policy, and electricity coverage. Part B evaluates the options available to improve sector efficiency, ensure financial sustainability, promote the diversification of energy sources, and increase electrification coverage.Publication Energy Storage for Mini Grids(Washington, DC: World Bank, 2024-01-05)This report specifically focuses on battery energy storage in decentralized off-grid mini grids located in remote areas. It provides an overview of battery technologies used in mini grids globally, demand forecasts for various battery technologies, a comparison of characteristics of different batteries, an exploration of costs and trends in battery technologies, case studies, and recommendations. It also includes appendices that offer a broad overview of mechanical, electrochemical, and thermal storage, as well as performance optimization of lead acid batteries in mini grids.Publication From Sun to Roof to Grid - The Economics and Policy of Distributed PV(Washington, DC: World Bank, 2024-04-02)From Sun to Roof to Grid: The Economics and Policy of Distributed Photovoltaics explores the benefits, challenges, and risks of DPV, with special attention to the economics of its deployment and its uses for utilities. The challenges addressed include inadequate electricity supply, energy access for low-income groups, natural disasters, decarbonizing the grid, and supply diversification. The report also offers a new paradigm to design policy packages for systems with more decentralized generation. In the new paradigm, DPV facilities can be better promoted by aligning the incentives of various stakeholders and distributing costs and benefits in a fair and efficient manner. The report also discusses the risks of DPV technology, and the means of mitigating them. Finally, it offers a comprehensive analysis of the benefits and advantages of DPV technology

Publication Case Study 2 - Andhra Pradesh, India : Participation in Macroeconomic Policy Making and Reform(Washington, DC, 2003-03)For the past six years, the State of Andhra Pradesh in India has been at the vanguard of efforts to modernize the economy and the state while pursuing policies to improve the lives of the poorest. The Chief Minister and head of the ruling Telugu Desam Party (TDP), Mr. Chandra Babu Naidu, is known by some as the "Laptop Minister" for his modernizing initiatives. He has reached out to international organizations and investors but has also maintained his base of support at home, in part through expanded programs in education, health, and rural development. "I have initiated so many things," Naidu said. "They are going on and will pay off after some time. But people need something today." The challenges facing the government are daunting. Andhra Pradesh (AP) is one of the largest and poorest states in India. Its population of almost 80 million approaches that of the Philippines, the 13th most populous country in the world. Even as its high-tech industries develop rapidly, AP's overall literacy rate remains a modest 44% and one-third of the population lives in poverty.Publication Kingdom of Morocco : Poverty Update, Volume 1. Main Report(Washington, DC, 2001-03-30)According to the 1998-99 Living Standards Measurement Survey conducted in Moroocco, poverty showed a disturbing increase during the 1990s, regardless of how poverty is measured. This report updates the poverty profile for Morocco following the comprehensive approach suggested by the latest World Development Report (see report no. 20888 for an overview of this report). It presents a detailed analysis of 1) Poverty trends in the 1990s (Chapter 2), 2) which factors are key in explaining the observed increase in poverty (Chapter 3), and 3) the support given to the poor by Government intervention (Chapter 4). An overview of the main initiatives taken by the authorities as well as by nongovernmental organizations and private businesses in the late 1990s is presented in the first chapter; their effects, though not captured by the 1998/99 data, are likely to have a significant impact on poverty reduction in the coming years.Publication Improving Access to Medicines in Developing Countries : Application of New Institutional Economics to the Analysis of Manufacturing and Distribution Issues(World Bank, Washington, DC, 2005-03)This paper examines alternative frameworks for empirical analysis of supply side activities, namely, the manufacture and distribution of medicine, through the application of New Institutional Economics (NIE) concepts. Attention is focused particularly upon the potential utility of ideas from agency theory, transaction cost analysis and contemporary ideas from strategy theory. The major purpose of this paper is to use these theoretical frameworks to provide insight for policy makers, when faced with specific situations, whether in an international agency, or a private company, or in defining a national strategy. The analysis attempts to show the importance of distinctions between ideas of 'make' or 'buy', between 'national self sufficiency' and 'international purchasing' strategies, the limitations of contractual agreements under market governance and the crucial linkages between strategy formulation, strategy implementation and the necessary capabilities to achieve successful performance in practice. The current international situation on the investment, location and capacity of pharmaceutical manufacturing is reviewed and likely future scenarios suggested. Correspondingly current patterns of trade in medicines and their likely development within the context of the WTO and bilateral trade agreements are discussed. Against this background the promise and the pitfalls for new forms of public-private partnerships, which may offer attractive alternatives to conventional structures are evaluated. The implications of alternative future strategic options for national governments in setting the balance between health and industrial policies are examined and in particular the extent to which a national manufacturing capability should be developed or sustained. Similarly the scope for improving low cost distribution systems for medicines, based upon a mix of public and private sector channels, is assessed. We conclude with suggestions for further development of a transaction-based framework.Publication Strategic Planning for Poverty Reduction in Vietnam : Progress and Challenges for Meeting the Localized Millennium Development Goals(World Bank, Washington, DC, 2003-01)This paper discusses the progress that Vietnam has made toward meeting a core set of development goals that the government recently adopted as part of its Comprehensive Poverty Reduction and Growth Strategy (CPRGS). These goals are strongly related to the Millennium Development Goals (MDGs), but are adapted and expanded to reflect Vietnam's national challenges and the government's ambitious development plans. For each Vietnam Development Goal, the authors describe recent trends in relation to the trajectories implied by the MDGs, outline the intermediate targets identified by the government, and discuss the challenges involved in meeting these. Relative to other countries of similar per capita expenditures, Vietnam has made rapid progress in a number of key areas. Poverty has halved over the 1990s, enrollment rates in primary education have risen to 91 percent (although there is a quality problem), indicators of gender equity have been strengthened, child mortality has been reduced, maternal health has improved, and real progress has been made in combating malaria and other communicable diseases. In contrast, Vietnam scores worse than other comparable countries in the areas of child malnutrition, access to clean water, and combating HIV/AIDS. A number of important crosscutting issues emerge from this analysis that need to be addressed. One such challenge is improving equity, both in terms of ensuring that the benefits of growth are distributed evenly across the population and in terms of access to public services. This will involve addressing the affordability of education and curative health care for poor households. Improvements in public expenditure planning are needed to align resources better to stated desired outcomes and to link nationally-defined targets to subnational planning and budgeting processes. There is also a need to address capacity and data gaps which will be crucial for effective monitoring.Publication From Sun to Roof to Grid(World Bank, Washington, DC, 2021-10-18)As the world’s fastest-growing local energy technology, distributed photovoltaics (DPV) has upended the traditional paradigm of one-way power flow from the grid to consumers.
