Ghana has commenced the final phase of the Kumasi–Anwomaso Transmission Line Upgrade and transformer replacement at the Kumasi (Ahodwo) Substation. This critical infrastructure project will replace an aging 19-kilometre single-circuit line, currently rated at 364 megawatts (MVA), with a modern double-circuit line capable of delivering nearly 1,000 megawatts.
Simultaneously, the Ghana Grid Company Ltd (GRIDCo) will install a new 145 MVA transformer at the Ahodwo Substation, replacing an existing 66 MVA unit. This significant upgrade will nearly triple the transmission capacity, easing pressure on existing equipment and improving overall reliability for Kumasi and the wider Ashanti Region. The project addresses the region's growing residential, commercial, and industrial electricity demands.
This upgrade is a vital component of Ghana's broader strategy to enhance its national power infrastructure and ensure energy security. The existing transmission lines have been in service for over 30 years, making this intervention essential to prevent a potential collapse of the national grid. Reliable electricity supply is fundamental for economic growth and stability, supporting industries and improving living standards across the Ashanti Region.
Richmond Rockson, Spokesperson and Head of Communication for the Ministry of Energy and Green Transition, stated the upgrade will significantly ease pressure on existing equipment. He confirmed that 90 per cent of foundation works and 67 per cent of tower assembly are already complete. Dr. John Abdulai Jinapor, Minister of Energy and Green Transition, emphasized the project's urgency during a site inspection, warning that further delays could risk a total grid collapse. GRIDCo Chief Executive, Mr. Frank Otchere, added that substation upgrades are technically necessary to match the increased line capacity.
The remaining tasks involve dismantling the old line, erecting the remaining new towers, and stringing conductors. Contractor China Water Engineering has completed 56 of the 60 required transmission towers. While temporary outages will cause inconvenience, they are essential for delivering a stronger, more reliable, and higher-capacity electricity network. This upgraded network will support the long-term development of Kumasi, the Ashanti Region, and Ghana as a whole. Residents are urged to stay away from active construction areas and comply with safety instructions during this period.
