This technical guide is the second 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 focuses on the main functionalities, differences and benefits of various compensation devices that can be employed to increase system transfer capacity, system stability, power quality and flexibility to cope with increasing penetrations of renewables in the system. The applications of FACTS devices are associated with four essential technical enhancements of system capacity, system reliability, power quality and system controllability....

The levelized cost of electricity is the most common indicator used to compare the cost competitiveness of electricity-generating technologies. Several studies claim that some renewable energy technologies, particularly utility-scale solar photovoltaic and onshore wind, are cost-competitive with fossil fuel–based technologies. However, there is no consensus on this point considering the wide variations in factors that influence the levelized costs of electricity across countries and technologies. This study calculates more than 4,000 levelized costs of electricity for 11 technologies, varying key input variables. The study shows that the levelized costs of electricity for renewable electricity technologies, except concentrated solar and offshore...
This report provides a brief overview of the role of energy storage against the background of current trends in power systems with a particular emphasis on developing countries. It introduces the different ways in which storage can help meet policy objectives and overcome technical challenges in the power sector, it provides guidance on how to determine the value of storage solutions from a system perspective, and discusses relevant aspects of policy, market and regulatory frameworks to facilitate storage deployment. The document is intended to highlight relevant issues, provide guidance to policymakers and regulators in this relatively new area and identify...
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...

A report prepared by the Global Green Growth Institute (GGGI) in support of the Sustainable Energy Framework (SEF) developed by the Organisation of Eastern Caribbean States (OECS) Commission, as well as the goals of the Eastern Caribbean Solar Challenge. The report looks at the Electricity Sector Governance Framework and the Electricity Sector Statistics for the OECS countries. Click here to view
Battery technology is evolving at a breathtaking pace. As performance improves and costs fall, batteries are already critical for consumer electronics, such as mobile phones, and are paving the way for the electric vehicle market. The battery revolution doesn’t end there. Battery systems are also transforming intermittent renewable energy - such as solar and wind - by making them much more financially attractive. Investors are taking notice. But while the versatility of batteries makes them attractive, it is difficult to determine their economic value. Understanding where and why batteries are most successful remains challenging, as each situation is different based...
