Disco report cardQ1 2026

Nigeria’s electricity companies, graded by NERC’s own numbers.

Eleven distribution companies (Discos) own the last-mile grid. Each quarter NERC publishes how much of the electricity they receive is lost to bad wires, unbilled use, and uncollected bills (ATC&C losses), plus how many customers actually have meters. Ranked compiles the Q1 2026 report into a single worst-first league. In Q1 2026, all 11 Discos missed their ATC&C targets.

The league · worst-first by ATC&C losses

ATC&C = the share of received electricity a Disco fails to turn into collected revenue (technical + commercial + collection losses). Lower is healthier. The arrow compares against Q4 2025.

How NERC measures Disco performance

The numbers, defined

ATC&C loss %: Aggregate Technical, Commercial and Collection losses — computed as [1 − (billing efficiency × collection efficiency)]. Power lost in the wires, power consumed but never billed, and bills issued but never collected. Since Q2 2025 NERC computes billing efficiency in naira terms, and from Q1 2026 the allowed tariff is VAT-adjusted.
Metering rate %: Share of active registered customers with a meter (vs estimated billing) as of 31 March 2026. Lower metering = more “crazy bills” complaints — metering was 51% of all electricity complaints NERC logged this quarter.
Active registered customers: NERC’s post-April-2025 rebased count: customers vended or billed at least once in the last 12 months — not total connections. That is why these counts look lower than older “customer population” figures.
Why no “hours of supply” column?: NERC does not publish measured average supply hours per Disco — the service-band framework states committed minimums per feeder, not measured delivery. Rather than estimate, Ranked leaves the column out. When NERC publishes it, we’ll add it.

Cadence: NERC publishes a quarterly report 60–90 days after each quarter end; this page is refreshed each release. Customer complaint counts are published for only 8 of 11 Discos this quarter (Eko, Ikeja and Ibadan are absent from NERC’s own table), so we exclude them from the league. Best-ranked EKEDC still missed its own ATC&C target — no Disco earned a pass mark in Q1 2026.
