Nigeria’s electricity regulator has overhauled the rules for mini-grids, sharply raising the size at which private developers can build and operate decentralised supply. The Mini-Grid Regulations 2026, issued by the Nigerian Electricity Regulatory Commission on 10 April, replace the 2023 framework and lift the ceiling from 1 MW to up to 5 MW for isolated systems and 10 MW for interconnected ones.
The higher thresholds matter because the old 1 MW cap, set when the market was young, had become a constraint on anything beyond village-scale schemes. Allowing far larger plants opens the door to mini-grids that can serve clusters of businesses, agro-industrial sites and densely populated areas, not just remote communities. Isolated systems run independently of the grid; interconnected ones sit alongside the distribution network.
Anchored in the Electricity Act 2023, the regulations also tighten oversight and transparency. Operators below 1 MW must file annual reports and those above it quarterly, and the commission may publish aggregated data on permits, registrations and performance. The stated aims are to accelerate rural electrification, attract private capital, ensure fair tariffs and consumer protection, and improve coordination between mini-grid developers and the distribution companies.
The reform builds on a market that has already drawn private money. More than a hundred privately financed mini-grids are operating in Nigeria with a pipeline of several hundred more, as federal and World Bank programmes continue to channel capital and subsidy into the segment to close a wide rural access gap.
Why this matters
Why this matters for distributed power developers
Raising the cap to 5 and 10 MW reframes the mini-grid from a rural-access tool into a commercial-scale option. Plants of that size can underwrite supply to industrial clusters and large single sites, the same load profile that captive and embedded projects target. Clearer rules, defined reporting and formal coordination with the DisCos also lower the regulatory risk that has slowed private distributed projects.
For Nova Utilities, the direction of travel is favourable. Its embedded generation, including the plant supplying the Lagos Blue Line rail, sits in exactly the band the new thresholds enlarge, and a framework that rewards larger, well-run distributed assets widens the field Nova is built to operate in. Regulation, in short, is catching up with the model.
