In cold-climate regions of developing countries, access to a reliable and affordable heat supply is critical to the well-being of the rural and peri-urban poor, who enjoy only limited access to district heating, natural gas, and electricity networks. Most of them have long relied on solid fuel-fired, traditional heating stoves or simple low-pressure boilers (LPBs), which are fuel-inefficient, leaky, and highly polluting both indoors and outside. Having access to high-efficiency, low-emissions (HELE) heating stoves offers under-served households a cost-effective, intermediate solution until fuel-switching to gas or electricity is possible. Recent World Bank- supported winter heating pilot programs in the Central Asian countries of Tajikistan and Kyrgyzstan brought to market a small number of advanced, solid fuel-fired space heating and cooking stoves. This technical report aims to document the Central Asia pilot experience with HELE heating technologies and their potential use as a cost-effective, intermediate solution for millions of underserved households for improving health and reducing household air pollution, energy poverty, and climate impacts.

The Handbook for practitioners and decision makers seeks to raise awareness among utility managers, decision makers, and other stakeholders of the importance and benefits of developing robust operation and maintenance (OandM) strategies for existing and greenfield hydropower plants. This handbook also aims at providing guidance for owners in preparing and implementing a long-term OandM strategy, defined as an informed set of high-level information (including a diagnosis) and decisions towards effective and safe OandM of hydropower facilities, including (i) objectives to be reached, (ii) activities and organizational decisions to reach these objectives and (iii) adequate resources (human, financial...). Through eight steps, this handbook proposes a framework and processes to establish an OandM strategy adapted to local contexts. It also presents the basic principles of OandM for hydropower and provides examples of the consequences of inadequate OandM policies, programs, and procedures. The handbook was developed along and benefited from the lessons learned of six case-studies in Brazil, Pakistan, Nigeria, Liberia, Uganda, and Uruguay/Argentina and which are depicted in the companion report Operation and Maintenance Strategies for Hydropower: Six Case Studies. They gather examples and lessons learned from the implementation of OandM strategies, while sharing views on remaining challenges and future directions.

Niger is a vast, landlocked, and mostly arid Sub-Saharan country, located in the heart of the Sahel region, with a rapidly growing population, estimated at 22.4 million (World Bank 2018a), of which the majority lives in rural areas. Despite considerable progress in the area of poverty reduction, extreme poverty remains very high, at an estimated 41.5 percent in 2019, affecting more than 9 million people in a country prone to climate risk and insecurity. The World Bank, with support from the Energy Sector Management Assistance Program (ESMAP), has launched the Global Survey on Energy Access, using the Multi-Tier Framework (MTF) approach. The survey's objective is to provide more nuanced data on energy access, including access to electricity and cooking solutions. The MTF approach goes beyond the traditional binary measurement of energy access, for example, 'having or not having' a connection to electricity, 'using or not using' clean fuels in cooking, to capture the multidimensional nature of energy access and the vast range of technologies and sources that can provide energy access, while accounting for the wide differences in user experience.

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.

The principal strategic challenges that the electricity sector in Moldova faces are to increase the security of electricity supply by diversifying sources, and to provide affordable, reliable, and sustainable energy services. To some extent this could be achieved by increasing and/or rehabilitating local generation capacity where economically justified. In addition, establishing an effective interconnection with the European Network of Transmission System Operators for Electricity (ENTSO-E) would enable the import of competitively priced power from the Energy Community (EnC) and would help overcome Moldova's electricity sector challenges. Although Moldova joined the EnC in 2010 after having implemented major and successful sector reforms, its electric power system is physically still part of the former Soviet Union's Integrated Power System/United Power System (IPS/UPS) and is effectively not interconnected with the EU/EnC's Internal Energy Market (IEM). This sector Study provides guidance to the government on significantly improving Moldova's security of energy supply via interconnection with ENTSO-E and therefore with the EU/EnC's internal energy market. The study consists of two main parts: (i) electric power system planning; and (ii) power market design, plus associated annexes.

The recent advances in battery technology and reductions in battery costs have brought battery energy storage systems (BESS) to the point of becoming increasingly cost-effective projects to serve a range of power sector interventions, especially when combined with PV and where diesel is the alternative, or where subsidies or incentives are used. Quantifying the economic impact of BESS requires a high level of temporal granularity in the analysis, because the time-steps required for a reliable assessment of costs and benefits are much shorter than the usual annual time steps of many power sector investment projects. In short, there is as yet still limited experience in the economic and financial analysis of BESS investment projects particularly, in developing countries, and one cannot yet set out with clarity what constitutes best international practice. This report sets out the principles and practices of BESS economic analysis as required for the World Bank's appraisal of investment projects that cover the range of BESS projects likely to be encountered by the Bank over the next few years.

Developed in the context of the rapidly growing demand for space cooling and the critical need for access to affordable space cooling solutions, this primer aims to introduce a broad audience to the topic of space cooling and its key considerations, and to help initiate and advance sustainable space cooling into policy discussions and investment considerations in developing countries. The global energy use for space cooling is projected to grow three-fold between 2016 and 2050, with a majority of this growth occurring in developing countries. While the growing need for space cooling is in alignment with the developmental needs of countries, this growth must be addressed with carefully designed strategies and solutions to avoid severe economic, power system, and environmental impacts. Underscoring an integrative approach to space cooling, the primer provides with an overview of strategies that reduce the cooling loads of buildings by applying building efficiency measures that enhance thermal performance, serve the cooling load as efficiently as possible through appropriate choice of cooling solution and utilization of most efficient cooling equipment available, and optimize the performance of cooling through their operation. Discussing the barriers to implement sustainable space cooling, the primer also presents demonstrated space cooling intervention strategies that can help overcome these barriers, with over 100 real-world examples and implementation considerations included in the Compendium.

Coal plants worldwide are grappling with low-capacity utilization levels and environmental issues; and have not only become unprofitable to utilities, but also uneconomical to customers. Developed countries with significant coal capacities such as Australia, Canada, Germany, the United Kingdom (UK), and the United States (US), are taking different approaches to wean away from coal. One such approach includes retiring and repurposing coal plants for various productive end uses, including solar plants, wind plants, data centers, and energy storage. Developing countries may gain much from the experience of their developed counterparts. Against this backdrop, the authors briefly examine the power situation in three developing countries, namely, South Africa, Chile, and India, based on their economic prowess within respective regions, predominance of coal in economic activities, and vulnerability to climate change, which make an interesting case for an analysis of repurposing coal plants in developing countries. This study presents the concepts and components of a cost-benefit analysis needed for a coal plant repurposing project.

China has developed one of the most comprehensive and effective sets of energy efficiency policies and programs in the world. This has been an arduous task over decades, involving the government, businesses, and civil society. Although success has abounded in many areas, China's programs are not perfect, and the development process has often been one of improving, adjusting, and reinforcing. Some of the strengths of China's effort have been (a) good organization, (b) focus on overcoming implementation difficulties at local levels as well as development of national policies and programs, (c) an effective blending of market-based energy efficiency investment and service mechanisms with new law-based regulations, and (d) investments in institutional development to provide the foundation for long-term gains. The process, experience, and results of the 40-year effort provide an amazingly rich bank of lessons for other countries with aspirations for energy efficiency gains, which this report strives to describe. One of the most telling macro indicators of China's success is the reversal of a trend of increasing energy use per unit GDP beginning in 2006 and continuing thereafter, delinking growth in energy consumption from growth in GDP. Energy use per unit GDP had fallen during the 1980s and 1990s, in part due to energy conservation efforts but mainly due to economic structural change as China's economy began to mature. This changed in the early 2000s, however, as yet more rapid industrial growth brought increases in China's energy intensity. China's leadership recognized that this continued resource-intensive development over the long haul was physically almost impossible, economically inferior, and environmentally unacceptable. With calls to build a less resource-intensive society, the country sharply increased its efforts to improve energy efficiency, building on past programs and adding new ones in a comprehensive effort. The focus was on achieving results. The trend of increasing energy intensity was bent downward, and energy intensity began to decline again, even as rapid industrial and economic growth continued.
