Minister of Energy and Green Transition Dr John Abdulai Jinapor has toured the Kumasi-Anwomaso Transmission Line Upgrade (K1–K2 Project), describing it as a key investment to strengthen electricity supply and improve the stability of power in Kumasi and across the Ashanti Region.
The update was shared in a post on X on Friday, July 17, 2026, by the Minister’s spokesperson and Head of Communications at the Ministry of Energy and Green Transition, Richmond Rockson.
According to the statement, the project is expected to significantly expand electricity transmission capacity while reinforcing the region’s power network.
“The Kumasi–Anwomaso Transmission Line Upgrade is a strategic investment aimed at strengthening electricity supply in Kumasi and the wider Ashanti Region,” the statement said.
The project forms part of the government’s broader efforts to modernise Ghana’s electricity transmission infrastructure and improve the quality and reliability of power supply for households, businesses and industries in the Ashanti Region.
As part of the upgrade, the existing 19-kilometre, 364MVA single-circuit transmission line linking the Anwomaso and Kumasi substations is being replaced with a modern double-circuit transmission line rated at 2 × 488MVA, giving it a combined capacity of 978MVA, more than twice the current level.
In addition, the Ghana Grid Company (GRIDCo) is replacing one of the existing 66MVA transformers at the Kumasi (Ahodwo) Substation with a new 145MVA transformer to improve the reliability, resilience and stability of electricity supply.
“The new double-circuit transmission line will more than double the transmission capacity between the Anwomaso and Kumasi substations, while the new transformer will significantly enhance the reliability, stability and resilience of power supply,” the statement noted.
Dr Jinapor also announced that the project will enter its final phase on Monday, July 20, 2026, warning that some consumers could experience temporary and localised power interruptions while engineers complete the remaining works safely.
He appealed to residents and businesses in Kumasi and the wider Ashanti Region to cooperate with the power utilities during the exercise.
“As the project enters its final phase, some customers may experience temporary and localised interruptions to electricity supply to enable the works to be carried out safely,” the statement said.
The Minister assured the public that GRIDCo and the Electricity Company of Ghana (ECG) would work together to minimise disruptions by issuing advance notices and restoring electricity as quickly as possible.
“GRIDCo and ECG will work closely together to minimise disruptions, provide advance public notices and restore power supply as quickly as possible,” he assured.
