Ghana Government Begins Anwomaso-Kumasi Power Line Upgrade to Tackle Low Voltage

The Government of Ghana has begun reconstructing the 161kV transmission line between Anwomaso and Kumasi to improve power supply and resolve low voltage challenges in Kumasi and the Dunkwa mining enclave. This is according to a report by Joy News on Tuesday, 8 July.

The project involves rebuilding a 12-kilometre section of the existing 161kV single-circuit line between the Kumasi and Anwomaso substations. It is being upgraded to a double-circuit line using twin bundle conductors mounted on steel lattice towers.

The reconstruction is undertaken by the Ghana Grid Company (GRIDCo). It forms part of ongoing efforts to strengthen Ghana’s power infrastructure and ensure a more stable electricity supply to major urban centres.

Once completed, the upgrade is expected to improve voltage levels and transmission reliability across the Ashanti Region, especially in Kumasi and surrounding communities.

Alongside the line upgrade, substation expansions and the Ameri power plant relocation are reportedly underway. These combined efforts are expected to stabilise voltage levels and improve transmission reliability in the Ashanti Region by the end of the year.

According to the energy data platform GlobalData, the project is under construction. Although initially scheduled for commissioning in 2023, some key milestones have now been reached, and work continues on the ground.

In addition to this, the government has rolled out other electricity initiatives in 2025 to improve the national grid. In May, Energy Minister John Abdulai Jinapor directed the Electricity Company of Ghana (ECG) to deploy 200 new transformers in Accra and other urban centres.

Earlier in March, Parliament approved GH₵1.2 billion for the Ministry of Energy and Green Transition. The funding will support the installation of one million smart meters under the “Programme for Results” and the launch of the “Government Goes Solar” initiative. It also covers the Accra-Kumasi transmission line project work, further expanding the country’s power infrastructure.
