In a statement issued at 8pm on Tuesday, Kenya Power said the outage experienced in sections of Nairobi and parts of North Rift, and Western regions was caused by a “system disturbance”.

“We have lost electricity supply affecting parts of North Rift, Western and sections of Nairobi due to a system disturbance affecting one of our major power transmission lines,” reads the statement.

The electricity company however assured that an operation is underway to restore power supply.

“Our engineers are working to restore the electricity supply to the affected areas at the earliest opportunity. We apologise to our customers for the inconvenience caused,” said Kenya Power.
