This followed the retirement of Dr Ben Chumo, whose term ended January 6, after being at the helm of the Company since January 2014.
Speaking during the appointment, KPLC chairman Kenneth Marende, said the Board was confident that the Company would run smoothly under Tarus' watch, as recruitment for a substantive CEO begins.
"Tarus will play a key role in entrenching the Company as the leader in electricity sub-sector by aggressively queuing each business growth and diversification,'' said Marende.
On his part, Chumo cited the multi-billion Last Mile Electricity Project that Kenya Power is implementing on-behalf of the national government, saying the Company currently has over Sh65 billion loan received from various donor community, supporting the project.
Tarus who had been serving as KPLC general manager Finance Division for two years, expressed optimism that he would turn around the Company for the better.
The Board's efforts to extend Chumo's term was blocked by the Employment and Labour Relations Court after Activist Okiya Omtata petitioned the Court, barring the Board from recommending Chumo's term extension by the Energy Cabinet Secretary.
