Nigeria’s Rural Electrification Agency (REA) and a consortium of development finance institutions and private investors have closed a $188 million fund to finance 191 megawatts of new solar capacity, marking one of the largest coordinated distributed-energy investments in sub-Saharan Africa this year.
The facility, structured as a blended finance vehicle, will deploy capital over an 18-month period across multiple solar mini-grid and interconnected projects. The REA said the fund targets underserved commercial and residential clusters across all six geopolitical zones, with first power expected within nine months of financial close.
Unlike earlier government-led electrification programmes, the new fund draws a significant share of its capital from commercial lenders and impact investors, including AfricaGoGreen Fund, All On, and Chapel Hill Denham’s Nigeria Infrastructure Debt Fund. Development finance institutions, including the World Bank–backed Nigeria power sector recovery and electrification programmes, and the African Development Bank’s Sustainable Energy Fund for Africa, are providing first-loss guarantees and concessional tranches to reduce risk and crowd in private investment.
“This is not a grant-funded pilot. It is a repeatable, market-rate vehicle designed to scale,” said a senior REA official familiar with the transaction, speaking on condition of anonymity because final legal sign-offs are pending. “We are showing that Nigerian solar risk can be priced, managed, and absorbed by private balance sheets.”
The 191 MW target represents nearly a tripling of REA’s currently operational off-grid solar capacity, which stood at roughly 70 MW as of the third quarter of 2025. For context, that additional generation is equivalent to taking a modest natural gas peaker plant off the national grid while serving an estimated 1.5 million people and 50,000 micro-enterprises currently relying on diesel generators costing $0.40–$0.60 per kWh.
Bankers involved in the transaction note that the fund’s structure, combining project-finance tenor of up to 12 years with a tariff-based revenue model anchored by anchor-buyer commitments from telecom tower operators and agricultural processors could become a template for future renewable energy auctions in Nigeria.
Still, currency volatility remains the single largest threat. The naira’s 40% depreciation against the dollar over the past 18 months has forced several mini-grid developers to renegotiate power purchase agreements. The fund addresses this by holding a dedicated foreign-exchange hedging reserve and requiring tariff indexation to the official exchange rate for contracts exceeding 5 MW.
grid encroachment, the risk that national utility lines eventually reach mini-grid service areas is being managed through buyout provisions and asset-transfer agreements with the Transmission Company of Nigeria.
For global investors watching Nigeria’s energy transition, the fund offers a live case study in whether blended finance can truly crowd in institutional capital at scale. The REA expects to launch a second, larger facility by mid-2027 targeting an additional 400 MW of solar and battery storage.
“The era of relying solely on development dollars is over,” the REA official added. “This fund proves that with the right risk allocation, solar in Nigeria can compete with diesel on price and win on reliability.”
