Major cause of outages

The power outages come days after Kenya Power Managing Director Joseph Siror revealed that between 50 and 70 per cent of electricity outages across the country are caused by trees and vegetation interfering with power lines.

“The biggest challenge, if you look at most of our outages, I would want to tell the public that about 50-70% is because of trees, and the unfortunate thing you would recall is that about 2-3 years ago, we entered into a very intensive programme of cutting all the trees near our lines,” Siror said.
