The Energy and Petroleum Regulatory Authority (EPRA) recorded an average of 3.91 power interruptions per month for customers in the financial year ended June 2026, up from 3.67 the previous year.

Each interruption lasted an average of 3.23 hours, 0.66 hours longer than the 2.57 hours recorded in the year ending June 2025.

May 2026 saw the longest average outage at 5.49 hours, while September 2025 recorded the shortest at 2.11 hours.

The Customer Average Interruption Duration Index (CAIDI) for 2025/26 stood at 3.23 hours, 1.87 hours above the regulatory benchmark of 1.36 hours for the tariff control period.

CAIDI has risen each year since 2022/23, reaching its highest five‑year level in 2025/26.

The System Average Interruption Duration Index (SAIDI) increased to 13.16 hours for the year, a 3.74‑hour rise from 9.24 hours in the previous year.

Monthly SAIDI figures peaked at 27.33 hours in May 2026 and fell to a low of 7.18 hours in July 2025.

EPRA’s target for SAIDI was 1.5 hours, meaning the 13.16‑hour annual figure remains well above the regulator’s goal.

System losses fell to 21.38 % in the year ended June 2026, the lowest level recorded over the five‑year period.

Despite the decline, losses remain 488 basis points above the 16.5 % allowable limit for the 2025/26 tariff control period.

Technical and commercial losses together account for the gap between electricity generated and electricity billed, with meter tampering and illegal connections cited as key commercial loss drivers.
