The three‑month upgrade of the Kumasi‑Anwomaso transmission line, which began on 20 July, has seen 56 of the 60 towers installed and GRIDCo replace transformers at the Ahodwo sub‑station to support a new 1 GW capacity. Energy Minister Dr John Abdulai Jinapor warned that further delays could jeopardise grid stability. On 29 July, a disturbance on the national interconnected transmission system caused several generating plants to trip, triggering a simultaneous nationwide outage.
