The Ministry of Energy and Green Transition, in collaboration with the Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG), has announced that the final phase of the Kumasi–Anwomaso Transmission Line Upgrade and transformer upgrade at the Kumasi (Ahodwo) Substation will commence on July 20, 2026.
The Ministry said the projects form part of government’s efforts to strengthen electricity infrastructure to meet the growing energy demands of Kumasi and the Ashanti Region.
In a press release issued on July 16, the Ministry explained that Kumasi has for years relied on an ageing 19-kilometre single-circuit transmission line linking the Anwomaso (K2) and Kumasi (Ahodwo) (K1) substations.
Although the line has served the city reliably, it has become increasingly overloaded due to rapid population growth and commercial expansion, making it inadequate to meet rising electricity demand.
According to the Ministry, the K1-K2 Project will replace the existing 364MVA single-circuit transmission line with a modern double-circuit transmission line with a combined capacity of 978MVA.
The upgrade is expected to more than double the transmission capacity between the two substations, improve the reliability and resilience of electricity supply and create additional capacity to support future residential, commercial and industrial development.
The Ministry disclosed that about 90 per cent of the foundation works and 67 per cent of tower assembly have already been completed.
The remaining phase will involve dismantling the existing transmission line, erecting new transmission towers and installing new conductors.
To facilitate the works, 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.
GRIDCo and ECG said advance notices will be issued ahead of each planned outage, adding that every effort will be made to restore power before the evening peak demand period.
As part of the project, GRIDCo will also replace one of the existing 66MVA transformers at the Kumasi (Ahodwo) Substation with a new 145MVA transformer.
The Ministry said the transformer upgrade will significantly increase transmission capacity, improve operational flexibility, reduce the load on existing equipment and further enhance the reliability of electricity supply in Kumasi and surrounding communities.
Residents have been urged to stay away from designated construction areas and comply with all safety instructions issued by project personnel throughout the construction period.
The Ministry expects the final phase of the project to be completed within three months and appealed to residents and businesses for patience and cooperation.
It acknowledged that the planned outages may cause temporary inconvenience but stressed that 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 the country.
