Grid uptime by DiscoQ4 2025

Who is keeping Nigeria's lights on — and who isn't.

Eleven distribution companies (Discos) own the last-mile electricity grid in Nigeria. NERC publishes their performance each quarter — hours of supply, ATC&C losses, metering rates, customer counts. Ranked compiles them into a single worst-first league so you can see who is failing your neighbourhood.

How NERC measures Disco performance

Three numbers that tell the story

Average hours per day: Network-weighted across the Disco's feeders — counts the hours customers actually had power, not the hours Disco sent power to the substation. A 12-hour Disco is one where the average customer has electricity half the day.
ATC&C loss %: Aggregate Technical, Commercial and Collection losses. Sum of: power lost in the wires (technical), power consumed but not billed (commercial), and bills issued but not collected (collection). Lower is healthier. Above 40% = financially distressed.
Metering rate %: Share of customers on a prepaid or post-paid meter (vs estimated billing). Higher = customers pay only for what they use; lower = more "crazy bills" complaints. Tied directly to the National Mass Metering Programme rollout.

Cadence: NERC publishes a quarterly performance report 60–90 days after each quarter end. This page is refreshed when a new bulletin is released. Values shown are network averages; per-feeder performance varies. Some Discos are currently under regulatory intervention — the underlying numbers may not reflect ownership changes mid-quarter.
