Disco report cardQ1 2026
Nigeria’s electricity companies, graded by NERC’s own numbers.
Eleven distribution companies (Discos) own the last-mile grid. NERC reports billing and collection efficiency, the combined revenue-based ATC&C loss measure, and how many active customers 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 combines billing and collection losses in revenue terms. It is not a physical-energy loss or hours-of-supply measure. Lower means less revenue loss on this metric. 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. This is a metering measure, not a measurement of supply hours or complaint rates.
- Active registered customers
- NERC’s post-April-2025 rebased count: customers vended or billed at least once in the last 12 months, rather than 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.
This page retains the dated Q1 2026 report. A later source check does not turn it into a newer reporting period. Customer complaint counts are excluded from this comparison. Lowest-loss EKEDC still missed its own ATC&C target. This comparison concerns ATC&C targets only, not a general service-quality verdict.

Where to check: PDF p.40 / printed p.34, Table 6: billing efficiency, 2026/Q1 column; PDF p.42 / printed p.36, Table 8: collection efficiency, 2026/Q1 column; PDF p.45 / printed p.39, Table 9: MYTO targets and Q4 2025/Q1 2026 ATC&C losses; PDF p.64 / printed p.58, Table 18: active customers, metered customers and metering rates.
- ATC&C is a revenue-based billing and collection measure, not the share of physical electricity lost and not hours of supply.
- Table 18 reports 7,324,079 metered customers; the executive summary on printed page 9 instead says 7,324,097. This page uses Table 18, whose company rows reconcile to its total.
- From Q1 2026 the allowed tariff in billing-efficiency calculations includes VAT; this affects comparison with Q4 2025 (printed page 33, footnote 17).
- Active customers were rebased in April 2025: customers billed or vending at least once in a twelve-month period (printed page 58, footnote 29).
