Nigeria's Electricity Act 2023 quietly did three things that matter for anyone building mini-grids in this country.
First, it devolved generation, transmission, and distribution licensing to the states. For decades, an investor wanting to build a 250kW mini-grid in Ogun State had to navigate a federal process built for utility-scale plants. Now Ogun State has its own electricity regulator — SERC Ogun — with the authority to issue licences and approve tariffs for projects up to 100MW. As of May 2026, eight states have stood up SERCs, with another twelve expected by end of year.
Second, NERC's Mini-Grid Regulations 2023 (replacing the 2016 version on 29 December 2023) clarified the regulatory pathway at the 100kW–1MW tier. Below 1MW, a developer needs a permit, not a full licence. The processing target is 30 business days. Tariffs are filed at the state level and reviewed annually. Crucially, the new regulations strengthened exit-compensation rights — if the national grid arrives and absorbs your mini-grid customers, the DisCo has to compensate the mini-grid operator at a transparent formula. This is the single biggest investability change of the past decade.
Third, the Rural Electrification Agency's mandate was reaffirmed and expanded. The REA's results-based grant programme — funded by the World Bank's Nigeria Electrification Project and AfDB co-financing — pays developers up to USD 600 per verified connection, and the minimum-subsidy tender programme covers up to 75% of CAPEX for qualifying sites. Combined, REA has roughly USD 750 million of programmed finance through 2027.
The window is open. It will not stay open forever. Common Watt's strategy assumes the regulatory environment is roughly this favourable for the next three to four years; after that, the early-mover advantage compounds.
