A national blackout has hit the nation with only the Western part and the North Rift left unaffected.
This indicates that the Nairobi North line that brings power to the capital from the Ol Karia area may have become overloaded.
KPLC engineers are said to be working on resolving the issue.
Moves by the local community in Suswa and at Kajiado to block high voltage lines being built by Ketraco has left the nation vulnerable to such blackouts as the Nairobi North line cannot handle the additional capacity broyght y the 280Mw geothermal power plants at Ol Karia.
The Nairobi North line runs from OlKaria to the Dandora substation.
