ECG commissions a new power 33kV sub-transmission feeder in Obuasi

The Electricity Company of Ghana (ECG) has completed and commissioned a new 33kV sub-transmission feeder to strengthen the electricity supply to Obuasi and nearby communities in the Ashanti Region.

The new line, which was energised on August 24, 2025, is linked to an upgraded 50/66 MVA transformer installed by the Ghana Grid Company (GRIDCo). It comes after months of unstable supply that followed a fire which destroyed GRIDCo’s transformer serving the Obuasi Bulk Supply Point. The incident disrupted power for thousands of households and businesses across the area.

ECG deployed a very dedicated standby team of engineers who traveled weekly between Kumasi and Obuasi to manage the crisis. Working with GRIDCo and its contractors, the team was able to restore power within six weeks.

As part of the upgrade, ECG retired its 11kV cables and replaced them with new 33kV connections linking GRIDCo’s gantry to the company’s GIS panels at the Obuasi Substation. Officials say the move has significantly improved the network’s strength and capacity to meet demand.

Speaking at the commissioning, the General Manager of Ashanti Sub-Transmission, Ing. Peter Kofi Fletcher, praised the effort and teamwork that made the project possible.

“What we have achieved in Obuasi is proof of the power of collaboration and sacrifice,” he said. “Our engineers, GRIDCo, contractors, and even AngloGold Ashanti, who stepped in to support some communities with supply from their own transformer, were all instrumental in overcoming the challenges. Today, we can confidently assure Obuasi and its surrounding areas of a stable and reliable electricity supply. This project is not just about transformers and lines; it is about keeping homes lit, businesses thriving, and industries running.”

He also expressed appreciation tothe  staff of Ashanti Sub-Transmission, Ashanti South, GRIDCo, AngloGold Ashanti, and the contractors involved in the project.

With the successful commissioning, residents and businesses in Obuasi and adjoining communities can now expect a steady and efficient supply of electricity.
