Abstract
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 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 Grid Integration Requirements for Variable Renewable Energy(World Bank, Washington, DC, 2019-07)This technical guide is the first in a series of four technical guides on variable renewable energy (VRE) grid integration produced by the Energy Sector Management Assistance Program (ESMAP) of the World Bank and the Global Sustainable Electricity Partnership (GSEP). It provides a general overview of the intrinsic characteristics of VRE generation, mainly solar PV and wind, what the main challenges are along with some recommendations for VRE technical specifications, applicable standards, and essential testing. The main focus of the document presents a detailed outline of the essential requirements for VRE integration into the power grid. The requirements differ for different levels of penetration but would require fundamental grid compliance requirements that must be reflected in any grid. This document provides these requirements along with recommendations of advanced VRE integration requirements that could be reflected in the power system operations with these VRE resources. The compliance with the technical requirements where applicable is validated through extensive series of interconnection studies which are further elaborated in "STUDIES FOR GRID CONNECTION OF VARIABLE RENEWABLE ENERGY GENERATION PLANTS – Technical Guide 3".Publication Managing an Electricity Shortfall(World Bank, Washington, DC, 2010)Supply-demand tension has taken its toll in various countries around the world over the last several years. Governments and utilities have faced gaps between electricity supply and demand, which has led to blackouts and load shedding and translated into electricity shortfalls. While countries look to avoid the prospects of supply shortages by, inter alia, strengthening planning capacity and working to achieve a sounder and more sustainable electricity sector, the possibility of shortages in the future remains. This document summarizes the framework for action and a broad menu of options available to policymakers to bridge a supply demand gap in the short- to medium-term.Publication From Sun to Roof to Grid(Washington, DC: World Bank, 2023-10-16)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 A Strategy for Coal Bed Methane and Coal Mine Methane Development and Utilization in China(World Bank, Washington, DC, 2007)China is short of clean energy, particularly conventional natural gas. The proven per capital natural gas reserve is only 1/12th of the world average. However, China has large coal bed methane (CBM) resources with development potential which can be recovered from surface boreholes independent of mining and in advance of mining, and also captured as a part of underground coal mining operations. However, in order to meet its targets, the government must improve the administrative framework for CBM resource management, introduce more effective CBM or coal mine methane (CMM) development incentives, raise the technical capacity of the mining sector, expand gas pipeline infrastructure and promote gas markets in coal mining areas. In order to significantly reduce methane emission from coal mines and better exploit the gas recoverable from coal seams, the government should introduce measures to: strengthen the CBM/CMM policy, legal and regulatory framework to improve resource management; improve CMM availability and quality so more can be utilized; enhance incentives to promote expansion of CBM/CMM exploitation and destruction of surplus drained CMM; and Promote development of regional development strategies to take advantage of specific local advantages.

Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.Publication From Sun to Roof to Grid(Washington, DC: World Bank, 2023-10-16)Rapid growth of distributed photovoltaics (DPV) has upended how engineers traditionally think about electric power systems.

It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.Publication Europe and Central Asia Economic Update, Spring 2025: Accelerating Growth through Entrepreneurship, Technology Adoption, and Innovation(Washington, DC: World Bank, 2025-04-23)Business dynamism and economic growth in Europe and Central Asia have weakened since the late 2000s, with productivity growth driven largely by resource reallocation between firms and sectors rather than innovation. To move up the value chain, countries need to facilitate technology adoption, stronger domestic competition, and firm-level innovation to build a more dynamic private sector. Governments should move beyond broad support for small- and medium-sized enterprises and focus on enabling the most productive firms to expand and compete globally. Strengthening competition policies, reducing the presence of state-owned enterprises, and ensuring fair market access are crucial. Limited availability of long-term financing and risk capital hinders firm growth and innovation. Economic disruptions are a shock in the short term, but they provide an opportunity for implementing enterprise and structural reforms, all of which are essential for creating better-paying jobs and helping countries in the region to achieve high-income status.
