Kenya Power has announced a scheduled power interruption affecting parts of Nairobi, Kisumu, Nyeri, Laikipia and Embu counties on Thursday, April 23, 2026, as the utility company continues with routine maintenance works across its network.

“Good evening, Please be advised that there will be a scheduled power interruption as outlined in the attached notice: Date: Thursday, 23.04.2026 Time: 9.00 A.M. – 5.00 P.M,” Kenya Power said in a post on its official X account.

The utility later attached a detailed maintenance notice listing the affected areas and the duration of the blackout, which will run for eight hours from 9 am to 5 pm.

In Nairobi, the outage will affect parts of Gachie, Mirema and Ngong Road. In Gachie, customers around Stabex Petrol Station, Gachie Market, Redhill Baraka School, Muchugia Estate, Shamuka Road and Bishops Estate will be affected.

In Mirema, the interruption will cover Mirema Drive and Mirema Springs. Along Ngong Road, areas including Lenana School, Ngando Village, Santack Estate, Racecourse, Jamhuri Showground, Polo Club, Ayani Estate, Dagoretti Corner and the Meteorological Department will experience the blackout.

In Western Kenya, parts of Kisumu County will be affected, including Kajulu Water, Gita Market, Great Lakes University, Kianja and Nyabondo.

In the Mt Kenya region, several parts of Nyeri County will go without power, including Kihari, Waihara Market, Kabebero Market, Iriani Market, Thunguri Market, Kiirini Market, Othaya Boys High School, Githimbai Market and surrounding areas.

In Laikipia County, Mia Moja Secondary School, Kamuthanga, Matangi and Ngenia Primary School will be affected. In Embu County, Kamugu Market, Itiira Market, Kirie Market, Mukororai Market, Kathanje Market and nearby areas will also experience the interruption.

Kenya Power said the maintenance is part of efforts to improve service delivery and strengthen the stability of the distribution network.

While the utility did not link the scheduled outage to broader energy issues, the announcement comes at a time when electricity costs and supply stability remain under public scrutiny.

EPRA pushes regional cooperation

The Energy and Petroleum Regulatory Authority (EPRA) has recently said that regional cooperation will be key to improving affordability and reliability in the power sector. Speaking during a conference in Nairobi, EPRA Acting Director General Joseph Oketch said Africa must strengthen coordination to manage energy challenges.

“The challenges we are facing now are a good opportunity to collaborate across sectors and the region to collectively address vulnerabilities in our energy supply chains while building systems that are flexible, integrated, and informed by credible research,” Oketch said.

He added that fragmented national systems are no longer sustainable, noting that “collaboration remains the cornerstone of progress. The challenges we face cannot be addressed in silos.”

EPRA has also pointed to ongoing efforts to harmonise electricity markets and improve cross-border power trade in the region, which it says could help stabilise supply and reduce costs in the long term.
