The Ministry of Energy and Green Transition has announced that the final phase of the Kumasi–Anwomaso Transmission Line Upgrade (K1–K2 Project) and the transformer upgrade at the Kumasi (Ahodwo) Substation will begin on July 20, 2026, as part of efforts to improve electricity supply in the Ashanti Region.
The projects, being implemented by the Ghana Grid Company Limited (GRIDCo) in collaboration with the Electricity Company of Ghana (ECG), are aimed at strengthening the region’s electricity transmission infrastructure to meet rising residential, commercial and industrial demand.
According to the Ministry, Kumasi has for many years depended on an ageing 19-kilometre single-circuit transmission line linking the Anwomaso (K2) and Kumasi (Ahodwo) (K1) substations. While the line has served the city reliably, increasing population growth and commercial expansion have placed significant pressure on the infrastructure, making it inadequate to meet current electricity demand.
The K1–K2 Project will replace the existing 364MVA single-circuit transmission line with a new double-circuit line rated at 2 × 488MVA, giving a combined transmission capacity of 978MVA. The Ministry said the upgrade will more than double the transmission capacity between the two substations, improve the reliability and efficiency of electricity supply, and create additional capacity to support future development in Kumasi and surrounding communities.
The Ministry said the project has reached its final and most critical stage. As of July 16, about 90 per cent of foundation works and 67 per cent of tower assembly works had been completed. The remaining activities include dismantling the existing transmission line, erecting new transmission towers and stringing new conductors.
To facilitate the works safely, the existing transmission line will be de-energised, resulting in temporary and localised power interruptions for customers served by the Kumasi (K1) and Anwomaso (K2) substations during scheduled construction periods.
GRIDCo and ECG said they would issue advance public notices before each planned outage and would make every effort to restore electricity supply before the evening peak demand period.
In addition to the transmission line project, GRIDCo will replace one of the existing 66MVA transformers at the Kumasi (Ahodwo) Substation with a new 145MVA transformer. The Ministry said the upgrade would increase transmission capacity, improve operational flexibility, reduce loading on existing equipment and further enhance the reliability of electricity supply across Kumasi and nearby communities.
The Ministry urged residents to observe all safety measures by staying away from designated construction areas and complying with instructions issued by project personnel throughout the construction period.
The final phase of the project is expected to be completed within three months. The Ministry acknowledged that the planned power interruptions may cause temporary inconvenience but said the works are necessary to deliver a stronger, more reliable and higher-capacity electricity network to support the long-term development of Kumasi, the Ashanti Region and Ghana.
The announcement was signed by Richmond Rockson, Spokesperson and Head of Communication at the Ministry of Energy and Green Transition.
