Like many African nations, Nigeria has lagged behind Global North countries in shifting away from planet-warming fossil fuels and toward renewable energy. Solar power contributes just around 3 percent of the total electricity generated in Africa — though it is the world’s sunniest continent — compared to nearly 12 percent in Germany and 6 percent in the United States.

At the same time, in many African countries, solar power now stands to offer much more than environmental benefits. About 600 million Africans lack reliable access to electricity; in Nigeria specifically, almost half of the 230 million people have no access to electricity grids. Today, solar has become cheap and versatile enough to help bring affordable, reliable power to millions — creating a win-win for lives and livelihoods as well as the climate.

That’s why Nigeria is placing its bets on solar mini-grids — small installations that produce up to 10 megawatts of electricity, enough to power over 1,700 American homes — that can be set up anywhere. Crucially, the country has pioneered mini-grid development through smart policies to attract investment, setting an example for other African nations.

Nearly 120 mini-grids are now installed, powering roughly 50,000 households and reaching about 250,000 people. “Nigeria is actually like a poster child for mini-grid development across Africa,” says energy expert Rolake Akinkugbe-Filani, managing director of EnergyInc Advisors, an energy infrastructure consulting firm.
