What Nigerian regulation actually says about commercial solar installations
NEMSA, NERC's net-billing framework, tariffs and VAT — what a compliant commercial solar installation in Nigeria looks like from the buyer's side.

Commercial solar in Nigeria sits inside a real regulatory framework, and a buyer who knows its outline can separate credible contractors from improvisers in one meeting.
NEMSA and who may do the work
The Nigerian Electricity Management Services Agency certifies firms that carry out electrical installation work and inspects installations. Ask any prospective contractor for their certificate and read the exact title and status on it — 'applied for' and 'issued' are different things.
MGM states its own position exactly: NEMSA Corporate Certification file CC/CEIF/PR/09131 is on record and the certificate has not yet been issued. The NEMSA inspection fee on a new installation is passed through to the client at the official rate and shown on the quotation.
Grid export: possible future upside, not revenue
NERC's Net Billing Regulations 2026 create a framework for eligible systems to export surplus energy, subject to DisCo feasibility approval, an agreement, revenue-grade metering and inspection. What they do not yet create is a dependable revenue line: readiness on the distribution side is unproven.
Treat grid export as possible future upside. If a proposal in front of you books export income as a system benefit, ask which DisCo signed it.
Tariffs and VAT
Grid tariffs published by DisCos are ex-VAT; your delivered cost is the tariff plus 7.5% VAT. Any comparison a contractor shows you should say which side of VAT its figures sit on — and one that does not is telling you something about its other numbers.
What compliance looks like at handover
A compliant commercial installation ends with paper: test results against a documented commissioning plan (IEC 62446-1 is the international reference for grid-connected PV testing — ask whether it is in the contract), as-built drawings, warranty terms in writing, and a handover dossier your own engineer can review. If the handover is a handshake, the compliance was too.
