Ghana: Energy Minister Inspects Kumasi Transmission Line Upgrade

Ghana’s Minister for Energy and Green Transition, Dr. John Jinapor, has inspected the ongoing upgrade of the 161-kilovolt (kV) Ahodwo-Anwomaso transmission line in the Ashanti Region, a project expected to be completed within the next three months.

The upgrade will increase the line’s transmission capacity to about 1,000 megawatts (MW) from 364 MW to meet rising electricity demand in Kumasi and support power exports.

The project involves replacing the existing 19-km single-circuit, 364-megavolt-ampere (MVA) transmission line with a higher-capacity double-circuit line rated at 2 x 488 MVA, nearly tripling the current capacity.

As part of the project, the Ghana Grid Company (GRIDCo) will also upgrade one of the transformers at the Kumasi (Ahodwo) substation to 145 MVA from 66 MVA, a move expected to improve the reliability, stability and resilience of electricity supply.

Speaking to reporters during the inspection, Jinapor said measures would be put in place to minimise disruptions to electricity supply while the work is carried out.

“As we enter the final phase of construction from Monday, July 20, 2026, some customers may experience temporary and localised power interruptions to allow these essential works to be carried out safely,” he said.

“These temporary inconveniences are necessary to deliver a stronger, more reliable electricity network that will support the continued growth and development of Kumasi and the Ashanti Region.”

Jinapor urged residents and businesses to be patient during the construction period.

“Every effort will be made by GRIDCo and the Electricity Company of Ghana (ECG) to minimise disruptions and restore supply as quickly as possible. I thank the people of Kumasi for their patience, understanding and continued support,” he said.
