Kenya Power has announced planned maintenance that will leave parts of Nairobi and Kilifi counties without electricity on Sunday, April 12, 2026.

The utility firm said the works are part of routine upgrades and repairs on the distribution network.

“Good afternoon. Kindly note that the following areas will be on planned maintenance tomorrow, Sunday, 12/04/2026,” the company said in a notice posted on its official X account on Saturday, April 11, 2026.

It added that customers can check updates through its chatbot and self-service platforms.

The outage in the Nairobi region will affect parts of Machakos County, including Mombasa Road, Lukenya Village, Daystar University and nearby customers. Kenya Power said the maintenance will run from 8.00 a.m. to 6.00 p.m., a ten-hour interruption expected to disrupt homes, businesses and institutions along the corridor.

In the Coast region, parts of Kilifi County will also be affected between 9.00 am and 5.00 pm. The company listed Kikambala, Mavueni and areas around Mombasa Cement among those scheduled for power interruption.

The notice also included a wide range of customers, such as hotels, factories, schools, farms and residential estates spread across Mtwapa, Vipinga, Mnarani, Ganze and surrounding areas.

Rising outages, system losses

Kenya Power said the maintenance will support network stability and improve service delivery in the long term. The firm has, in recent months, increased such works as it responds to rising demand and pressure on the grid.

The announcement comes at a time when Kenya’s power sector is under scrutiny over reliability. According to recent data from the Energy and Petroleum Regulatory Authority (EPRA), consumers still experience an average of 8.39 hours of outages per month, far above the regulator’s target. The report also shows that more than 22 per cent of electricity is lost during transmission and distribution.

“System losses refer to electrical energy generated but lost during transmission and distribution, including unbilled energy from illegal connections, unmetered supply and meter tampering,” EPRA noted in its latest report.

Kenya Power has said ongoing upgrades aim to reduce outages and improve efficiency, but the impact of maintenance work continues to be felt by customers across the country. Businesses in affected areas are expected to rely on backup generators during the scheduled downtime.
