Kumasi-Anwomaso electrcity transmision line upgrade commences

Ghana is undertaking a critical upgrade of the Kumasi-Anwomaso electricity transmission line and replacing a key transformer at the Kumasi (Ahodwo) Substation. This intervention, a partnership between the Ministry of Energy and Green Transition, GRIDCo, and ECG, aims to significantly enhance power transmission capacity and reliability.

The project involves replacing an aging 19-kilometer single-circuit line, currently rated at 364 megawatts (MVA), with a modern double-circuit line capable of delivering nearly 1,000 megawatts. Concurrently, a new 145 MVA transformer will be installed at the Ahodwo Substation, replacing an existing 66 MVA unit. This upgrade is expected to nearly triple transmission capacity, alleviate pressure on existing equipment, and improve overall grid reliability.

According to Richmond Rockson, Spokesperson and Head of Communication for the ministry, the enhanced capacity will support the burgeoning residential, commercial, and industrial electricity demands of Kumasi and the wider Ashanti Region. He noted that 90% of foundation work and 67% of tower assembly are complete, with the remaining tasks including dismantling the old line and stringing new conductors. The contractor, China Water Engineering, has erected 56 of the 60 required transmission towers.

Minister of Energy and Green Transition, Dr. John Abdulai Jinapor, emphasized the project's urgency during a site inspection, warning that delays could risk a total collapse of the national grid. "The existing transmission lines have been in service for more than 30 years. We cannot postpone this project indefinitely. It is essential to safeguard Kumasi’s electricity supply," he stated, appealing for public patience during construction.

GRIDCo Chief Executive, Mr. Frank Otchere, confirmed the technical necessity of the substation upgrades to match the increased line capacity. While temporary outages may cause inconvenience, officials stress they are essential for a more robust and higher-capacity electricity network, vital for the long-term development of the region and the country.
