Kumasi to experience temporary power outages as GRIDCo begins major transmission line upgrade

Residents of Kumasi and surrounding communities are expected to experience temporary power outages from Monday, July 20, 2026, as the Ghana Grid Company Limited (GRIDCo), in collaboration with the Electricity Company of Ghana (ECG), begins a three-month project to upgrade the Kumasi-Anwomaso transmission line.

The project will increase the transmission line's capacity from 364 megawatts to 1,000 megawatts, nearly tripling its current capacity to meet the Ashanti Region's growing industrial and residential electricity demand while improving the reliability of the national grid.

Because ECG distribution lines intersect the transmission corridor, electricity supply will be interrupted in affected communities during active construction hours to ensure the safety of workers.
