For years, Nigerian solar was a survival tool: you installed panels because NEPA failed you, and whatever excess power your system generated simply evaporated. In June 2026, NERC changed the equation. The Net Billing Regulations 2026 — now officially in force — create, for the first time, a legal framework for eligible solar owners (“prosumers”) to export surplus electricity to their DisCo and earn credits that offset their bills.
But before you dream of your rooftop paying your NEPA bill, one number matters more than the headlines: the scheme covers systems from 50 kilowatt-peak (kWp) to 1.5 megawatt-peak (MWp) — which means it’s built for businesses, factories, schools, hospitals, malls and estates, not the typical 5 kWp home inverter setup. This guide gives you the honest full picture: what net billing actually is, who qualifies, the exact application steps, how the money works, and what smaller solar owners should do while the scheme matures.
📌 The quick version: NERC’s Net Billing Regulations 2026 (commenced early June) let eligible customers — prosumers — generate solar power for their own use and export the surplus to their DisCo’s network. Eligibility: you must be connected to a DisCo network, run a compliant renewable system, and — the big filter — fall within the 50 kWp to 1.5 MWp capacity band, which targets commercial/industrial and institutional installations rather than small homes. The process: apply to your DisCo, pass a technical feasibility assessment, sign a Net Billing Agreement, register with NERC, then get a bidirectional meter installed that records energy in both directions. The money: exported energy earns credits at a NERC-approved export tariff, automatically deducted from your bill each cycle — credits, not cash payouts. Eko DisCo is already moving on purchases. The context: Nigeria’s solar installs grew 141% in 2025 (Africa’s #2 installer), yet grid-connected solar was only ~0.2% of generation — this scheme is designed to change that. Home users: you’re not eligible yet at typical rooftop sizes — but right-sizing, batteries, and watching for the scheme’s expansion are your smart plays. Full regulations: nerc.gov.ng.
What Net Billing Actually Is (And What It Isn’t)
Strip the jargon and it’s simple. Your solar system powers your premises first. When it produces more than you’re using — a sunny afternoon with light load — the surplus, instead of being wasted, flows into the DisCo’s network through a special meter, and you receive energy credits for every kilowatt-hour exported. At the end of each billing cycle, those credits are deducted from the cost of the electricity you drew from the grid. NERC’s word for you in this arrangement is prosumer — producer plus consumer.
Two clarifications that save disappointment. First, it’s credits, not cash: you won’t receive bank transfers from your DisCo; you’ll receive a smaller bill (which, for a heavy consumer, is the same thing in effect). Second, net billing is not net metering: under classic net metering, every exported unit cancels an imported unit one-for-one at the retail rate. Under Nigeria’s net billing, exports are credited at a separate export tariff approved by NERC — typically set below the retail rate you pay for imports. The economics still work, especially against diesel, but self-consuming your own solar remains more valuable than exporting it: the scheme monetises your surplus, it doesn’t turn you into a power company.
The Eligibility Truth: 50 kWp to 1.5 MWp
Here’s the section most coverage glosses over. NERC’s framework applies to renewable systems — primarily solar PV — sized between 50 kWp and 1.5 MWp. For scale: a typical Nigerian home inverter-and-panels setup runs 3–10 kWp; a 50 kWp system is roughly the footprint of a serious SME, private school, clinic, cold-room business, filling station or small factory. The scheme, as Punch’s reporting put it plainly, targets medium and large consumers, not residential customers with small systems.
So who should be moving right now? Factories and industrial estates running big daytime solar; universities, schools and hospitals with large roof arrays; shopping malls, hotels and office complexes; telecom facilities; agro-processing and cold-chain businesses; and estates or clusters whose combined installations reach the threshold. Beyond eligibility, you must be connected to a DisCo network (fully off-grid sites can’t export to a grid they’re not on), and your installation must meet the technical standards in the regulations — professionally engineered systems with compliant inverters and protection, not improvised setups.
How to Apply: The Five Steps
The process NERC has laid out is refreshingly linear. Step 1 — Apply to your DisCo for participation; this triggers a technical feasibility assessment, where the DisCo evaluates whether your installation meets required standards and whether the local network can safely absorb your exports. Step 2 — Get approval and sign the Net Billing Agreement with the DisCo — the contract governing tariffs, metering and obligations. Step 3 — Register with NERC as required under the regulations; this formalises your prosumer status. Step 4 — Receive your bidirectional meter — unlike a normal meter, it records both the electricity you import from the grid and the electricity you export to it, and it’s the settlement backbone of the whole scheme. Step 5 — Start exporting and earning credits, applied automatically each billing cycle at the approved export tariff.
Practical advice for applicants: engage your solar installer/EPC early (the feasibility assessment is technical — single-line diagrams, inverter specs, protection settings), expect the DisCo’s network-capacity check to matter as much as your own equipment, and read the Net Billing Agreement properly — tariff terms, metering responsibilities and liability clauses are where the fine print lives. Eko DisCo has already signalled it’s buying, and other DisCos are onboarding — your own DisCo’s customer service is the entry door.
The Economics: Does It Actually Pay?
For qualifying businesses, the arithmetic is compelling. Commercial and industrial solar users in Nigeria were already saving 20–30% versus diesel self-generation before this scheme; net billing improves those economics further by monetising the surplus hours (weekends, holidays, low-load afternoons) that previously produced nothing. The credit rate — the export tariff — is set and approved by NERC, and because it offsets grid consumption billed at commercial rates, every exported unit directly shrinks one of your largest operating costs.
Three planning notes. Self-consumption first: since export credits are worth less than the retail rate you avoid, design and operate to use your own solar maximally, and export what’s genuinely surplus. The meter is the ledger: billing disputes die when the bidirectional meter is properly installed and sealed — insist on documentation at installation. Model before expanding: if you’re considering growing your array specifically to export, run the numbers against the actual export tariff in your agreement, not against optimistic assumptions — the scheme rewards surplus monetisation more than pure merchant generation.
Why This Matters (The Bigger Picture)
The timing is no accident. Nigeria recorded 141% year-on-year growth in new solar installations in 2025, becoming Africa’s second-largest solar installer after South Africa — yet as recently as 2024, grid-connected solar contributed only about 0.2% of total generation, because virtually all that capacity sat behind private fences. Net billing is the policy bridge: it turns isolated self-generation into distributed generation, gives DisCos power produced close to where it’s consumed (cutting transmission losses), and shares the grid burden. With Nigeria’s renewable market projected to reach 14.07 GW by 2031 (a 25.58% compound growth rate), the prosumer era is the growth story — and early participants get the learning-curve advantage.
Not Eligible Yet? What Home Solar Owners Should Do
If you run a 5 kWp rooftop, don’t uninstall anything — position yourself. Right-size and self-consume: shift heavy loads (pumping, washing, ironing, freezing) into solar hours so your panels’ output is used, not wasted. Consider storage: batteries capture the surplus the grid won’t yet buy from you, delivering the same bill-shrinking effect by another route. Keep your installation compliant and documented: if and when the scheme’s threshold widens to residential prosumers — the direction most net-billing regimes worldwide have travelled — compliant, professionally installed systems will onboard first. Think collectively: estates, clusters and cooperatives whose combined capacity crosses 50 kWp may find a shared route in; ask your estate association and installer. And watch NERC’s announcements — the commission has framed this as the beginning of distributed-generation reform, not the end.
FAQ: Selling Solar Power to the Grid in Nigeria
1. What are the Net Billing Regulations 2026?
NERC’s new framework (commenced June 2026) letting eligible customers — “prosumers” — generate renewable power, primarily solar PV, for their own use and export the surplus to their DisCo for bill credits at a NERC-approved export tariff.
2. Can I sell my home rooftop solar to the grid?
Not at typical home sizes yet — the scheme covers systems from 50 kWp to 1.5 MWp, targeting businesses and institutions. Most home setups are 3–10 kWp. Watch for future expansion, and consider estate/cluster routes.
3. How do I apply?
Apply to your DisCo, pass its technical feasibility assessment, sign a Net Billing Agreement, register with NERC, receive a bidirectional meter, then start exporting and earning credits.
4. Do I get paid cash?
No — exported energy earns credits at the approved export tariff, automatically deducted from your electricity bill each cycle. For heavy consumers, that’s cash by another name.
5. What is a bidirectional meter?
A special meter recording electricity in both directions — what you import from the grid and what you export to it. It’s installed for approved participants and forms the billing record for the scheme.
6. What’s the difference between net billing and net metering?
Net metering nets exports against imports one-for-one at retail rates. Net billing (Nigeria’s model) credits exports at a separate, NERC-approved export tariff — typically below retail — so self-consuming your solar remains more valuable than exporting it.
7. Which businesses benefit most?
Factories, industrial estates, schools and universities, hospitals, malls, hotels, telecom facilities, agro-processing and cold-chain operations — anywhere with large arrays and surplus daytime generation, especially on low-load days.
8. Is any DisCo actually buying yet?
Yes — Eko DisCo has moved on purchasing excess solar from users, and the framework applies across all DisCos, each running its own application and feasibility process.
9. What are the technical requirements?
Connection to a DisCo network, a renewable system within the 50 kWp–1.5 MWp band meeting the regulations’ technical standards, passing the DisCo’s feasibility assessment, and compliant metering. Professional installation documentation matters.
10. Where do I read the full regulations?
On NERC’s official website, nerc.gov.ng — the commission published the full Net Billing Regulations 2026 alongside its commencement notice.
The Bottom Line
Nigeria just crossed a line most energy markets consider transformative: solar owners can now legally earn from the grid instead of merely escaping it. For qualifying businesses and institutions — the 50 kWp-and-above class — the move is clear: call your DisCo, start the feasibility assessment, sign the agreement, register with NERC, and let a bidirectional meter turn your idle surplus into smaller bills, on top of the 20–30% you’re already saving against diesel.
For everyone else, the honest counsel is patience with positioning: self-consume aggressively, document your installation, explore cluster routes, and watch this scheme evolve — because with solar growing 141% a year here, the residential chapter is a question of when, not if. Either way, the era of wasted Nigerian sunshine is officially ending. Full details at nerc.gov.ng — and start the conversation with your DisCo this week.
