The Ghana Grid Company Limited (GRIDCo) has announced planned works on the 330kV Takoradi–Thermal–Anwomaso Transmission Line as part of efforts to connect a new power generation plant at Anwomaso in Kumasi to the national grid.
The announcement follows a temporary power outage that affected parts of Greater Kumasi on Sunday, December 21, 2025, after a minor fault at GRIDCo led to a reduction in electricity supply to the Electricity Company of Ghana (ECG).
In a press statement issued the same day, GRIDCo said the works are being undertaken by AKSA Energy to bring its newly constructed power generation plant at Anwomaso into operation.
According to GRIDCo, the plant, when fully commissioned, will add to Ghana’s generation capacity and significantly improve the reliability of power supply to Kumasi and surrounding communities.
As part of the commissioning process, an exercise is being carried out to safely connect the AKSA Anwomaso Generating Plant to the national power system via the 330kV transmission line. GRIDCo said the activity may require a temporary interruption of power supply to some customers for approximately three hours to allow for the safe termination and integration of the new substation.
Power supply to all affected customers is expected to be fully restored by 11:00 p.m. on the same day.
GRIDCo apologised for any inconvenience the temporary interruption may cause and assured the public that the works are necessary to enhance the stability and reliability of electricity supply in Kumasi and adjoining areas.
