Mini grids, previously viewed as a niche solution, can provide electricity to as many as 500 million people by 2030, helping close the energy access gap, according to a new World Bank report. The combination of falling costs, dramatic increase in quality of service, and enabling policies has made mini grids a scalable option to complement grid extension and solar home systems.
Mini Grids for Half a Billion People: Market Outlook and Handbook for Decision Makers is the most comprehensive study on mini grids to date. It provides policy makers, investors, and developers with insights on how mini grids can be scaled up. It takes stock of the global market and industry, analyses costs and technological innovations, and shows the importance of microfinance and income-generating uses of electricity.
Compared with main grid and solar home systems, mini grids are a more viable solution for areas with high population density and medium electricity demand. Extending main grid to serve remote communities is often prohibitively expensive. Globally, at least 19,000 mini grids are already installed in 134 countries, representing a total investment of $28 billion and providing electricity to around 47 million people. Most are deployed in Asia, while Africa has the largest share of planned mini grids.
At present the total mini grid investment in countries with low levels of electricity access in Africa and Asia totals $5 billion. It is estimated that $220 billion is needed to connect 500 million people to 210,000 mini grids in these regions by 2030. Across the globe, countries need to actively mobilize private sector investment. This can be achieved by setting up policies that support comprehensive electrification programs, promoting viable business models, and providing public funding, for example through performance-based grants.
“Mini grids are now one of the core solutions for closing the energy access gap. We see great potential for mini grid development at scale and are working with countries to actively mobilize public and private investment,” said Riccardo Puliti, Senior Director of Energy and Extractives at the World Bank. “The World Bank has been scaling up its support to mini grids while helping countries develop comprehensive electrification programs.
