This comes months after Kenya Power recorded its highest-ever electricity demand, reaching a new peak of 2,362.28 megawatts (MW).
In a statement on Wednesday, July 30, Kenya Power attributed the surge in demand to new customer connections and increased grid usage during the cold season.
The company said data from its National Control Centre indicates the record demand was registered on Wednesday, July 23.
It came weeks after a previous high of 2,325 MW was recorded on July 2, surpassing the earlier peak of 2,316 MW set in February this year.
Kenya Power reported that it connected 401,848 new customers during the financial year ending June 30, 2025.
According to the company, the current cold season has also played a significant role in pushing electricity consumption higher.
It reported that most households and businesses rely more on grid power to warm homes and offices.
"We are at various stages of implementation of the last mile connectivity projects that have been commissioned across the country. In addition to these projects, the Company is carrying out other connectivity projects targeting various customer categories, including commercial and industrial consumers. We expect that the onboarding of these customers will push electricity demand further," Kenya Power's Managing Director & CEO, Dr. (Eng.) Joseph Siror said.
He added: "The new peak demand is a testament to our commitment to drive national electricity access through the deployment of various electrification projects. When we look at our electricity dispatch figures, we realise that electricity demand has increased by 46 MW in the last five months since February, when we had the first peak demand this year. We expect the momentum to continue as we roll out more connectivity projects across the country."
