Kenya, April 9, 2026 - The Nairobi Metropolitan Region was the leading consumer of electricity in the country in the second half of 2025, accounting for almost half of the country’s total electric consumption.
 
According to a report by the Energy and Petroleum Regulatory Authority, the region utilised 44.24 per cent of the country’s electricity, after using 2,627.44 Gigawatt-hour (GWh), up from 2,415.44 GWh in a similar period last year.

Overall, national electricity consumption grew by 8.27 per cent from 5,484.54 GWh to 5,938.14 GWh, according to the authority.

The number of grid-connected customers increased by 182,195 to 10,216,952 during the period under review, according to the regulator.

"In the period under review, electricity generation was highest in December at 1,328.52 GWh, and lowest in September at 1,258.36 GWh. This is a notable improvement compared to a similar period in the previous year where the highest generation was 1,233.59 GWh in October 2024," EPRA said.
