Climate action efforts can tap solar mini grids that offer a lower greenhouse gas emission alternative compared to diesel-fueled systems and kerosene-based appliances. The World Bank’s Mini Grids for Half a Billion People: Market Outlook and Handbook for Decision Makers notes that to realize the full potential of solar mini grids, governments and industry must work together to systematically identify mini grid opportunities, drive costs down, and overcome barriers to financing.

“Kenya has deployed mini grids to serve communities that are not connected to the main grid,” said Mr Davis Chirchir, Cabinet Secretary Ministry. “Currently we have about 62 mini grids that are fully operational and 28, which are under construction. We hope to deploy more mini grids to close the energy access gap and ensure universal access to electricity by 2030.”

In Sub-Saharan Africa, 568 million people still lack access to electricity. Globally, nearly 8 out of 10 people without electricity live in Africa. At the current rate of progress, 595 million Africans will remain unconnected in 2030.

“While Africa remains the least electrified continent, it also has the biggest potential for solar mini grid deployment,” said Gabriela Elizondo Azuela, Manager of the World Bank’s Energy Sector Management Assistance Program (ESMAP). “Solar mini grids can reach populations today that would otherwise wait years to be reached by the grid.  They have the potential to transform the power sector in Sub-Saharan Africa. Through World Bank operations and advice to governments, ESMAP is helping take mini grids from a niche to a mainstream solution.”

The deployment of solar mini grids has markedly accelerated in Sub-Saharan Africa, from around 500 installed in 2010 to more than 3,000 installed today, and a further 9,000 planned for development over the next few years. This is the result of falling costs of key components, the introduction of new digital solutions, a large and expanding cohort of highly capable mini grid developers and growing economies of scale. In Africa, mini grids are on track to provide power at lower cost than many utilities. The cost of electricity produced by mini grids could be as low as $0.20/kWh by 2030, making it the least-cost solution for more than 60 percent of the population.

Important progress has been made in several African countries to accelerate the deployment of mini grids. In Nigeria, for example, a market-driven approach to mini grid development under the World Bank-supported National Electrification Project has catalyzed the deployment of more than 100 new solar-powered mini grids. In several countries such as Ethiopia and Zambia, new regulations and policy directives are making mini grids more attractive for private sector investment. In Kenya, a combination of geospatial planning, favorable policies and regulations, and a robust business model based on public-private partnership is underpinning the World Bank-supported Kenya Off-Grid Solar Access Project, which is targeting almost 150 new mini grids in areas with low electricity access rates.

Further acceleration is needed, however, to meet Sustainable Development Goal 7 (SDG7). Powering 380 million people in Africa by 2030 will require the construction of more than 160,000 mini grids at a cumulative cost of $91 billion. At the current pace, only around 12,000 new mini grids serving 46 million people will be built by 2030 at a total investment cost of approximately $9 billion.

The World Bank has committed more than $1.4 billion to mini grids over the next seven years, through 38 projects in 29 countries. The investment plans of the World Bank’s portfolio include the deployment of 3,000 mini grids by 2029, with the expectation of bringing electricity to more than 13 million people. This investment commitment is expected to crowd in more than $1 billion of co-financing from private sector, government, and development partners. In countries where the World Bank has an investment commitment in mini grids, the Bank’s investment represents on average about 25 percent of the total investment in mini grids in each country from governments, the private sector, and development partners.

Produced by the World Bank’s Energy Sector Management Assistance Program (ESMAP), the book, the Mini Grids for Half a Billion People: Market Outlook and Handbook for Decision Makers, identifies five market drivers that would help the mini grid sector achieve its full market and development potential:

1. Reducing the cost of electricity from solar hybrid mini grids to $0.20/kWh by 2030, which would put life-changing power in the hands of half a billion people for just $10 per month.
2. Increasing the pace of deployment to 2,000 mini grids per country per year, by building portfolios of modern mini grids instead of one-off projects.
3. Providing reliable electricity service to customers and communities would generate the demand for 3 million income-generating appliances and machines and expand services at 200,000 schools and clinics.
4. Leveraging development partner funding and government investment to “crowd in” private-sector finance, potentially raising $127 billion in cumulative investment from all sources for mini grids by 2030.
5. Establishing enabling mini grid business environments in key access-deficit countries through light-handed and adaptive regulations, supportive policies, and reductions in bureaucratic red tape.

The handbook is the World Bank’s most comprehensive and authoritative publication on mini grids to date.
