Parts of Nairobi have also seen power restored even as Kenya Power technicians work to address the power outage.
Kenya Power has commenced the restoration of power in some parts of the country following a nationwide power outage that started on Friday, August 24, at 9 pm.
On Saturday morning, the utility firm confirmed that it restored power in the Mt Kenya region hours after the system failure occurred.
Areas within the Nairobi Metropolitan considered crucial to the country's operations, also saw their power restored on Saturday morning.
Kenya Power added that its teams moved quickly to power up critical infrastructure such as airports and hospitals.
Kenyans were asked to be patient even as its technicians across the country worked around the clock to restore their services to normalcy.
According to Kenya Power, the countrywide power outage was caused by a fault in one of its production plants.
However, the specific station that witnessed the fault and the specific cause of the fault was yet to be established.
"Our teams are working to restore electricity to all areas across the country that were affected by the outage. We apologise to our customers for the inconvenience caused and thank them all for their patience," read the statement in part.
"We are working in collaboration with teams from all involved sector partners to facilitate speedy restoration of power supply in the shortest time possible."
The nationwide power outage majorly affected Western Kenya, Rift Valley, Mt Kenya regions, and the Nairobi Metropolis.
It stalled economic activity in parts of the country, with many Kenyans relying on the national utility firm for the supply of power in their homes and businesses.
Some institutions also experienced system failure with their backup generators, resulting in further delays in the delivery of services. Among those affected were Jomo Kenyatta International Airport (JKIA).
However, the Kenya Airports Authority (KAA) confirmed that operations had been restored at the facility.
