The Electricity Company of Ghana‘s (ECG) Ashanti sub-transmission division has entered a collaborative agreement with the Ghana Grid Company (GRIDCo) to enhance supply capacity and meet the rising electricity demand in the region.
This partnership was formalized during a meeting held at GRIDCo’s headquarters in Anwomaso.
According to the agreement reached during the meeting, there are plans to install a 145MVA power transformer between GRIDCo and ECG Bulk Supply Points.
This upgrade aims to replace one of the existing three 50MVA transformers, thereby increasing installed capacity to address growing load demands, particularly during peak hours, typically between 7 pm and 11 pm.
Previously, the 50MVA transformers at the Anwomaso Bulk Supply Point sometimes operated at maximum capacity during peak periods due to increased demand.
However, with the planned installation of the 145MVA transformer, the total installed capacity will rise to 245MVA, compared to the current 150MVA provided by three 50MVA transformers.
Both parties anticipate that this initiative will improve supply capacity and reliability across the region.
Additionally, discussions during the meeting also focused on upgrading the Obuasi and Konongo Substations with 50/66 MVA transformers to meet growing industrial needs in those areas and enhance supply reliability.
Further discussions included plans to dispatch another 145MVA transformer to Ridge BSP shortly to increase supply capacity for the station and the broader region.
Following these discussions, a site visit was conducted to assess suitable installation locations for the new transformer.
Ing. Peter Kofi Fletcher, General Manager for Ashanti Sub-transmission, and his team collaborated closely with the GRIDCo team to identify optimal sites, aiming to minimize material costs associated with cable laying and civil works.
Currently, the region is served by two Bulk Supply Points, Anwomaso and Ridge, which distribute high-voltage power to primary substations, subsequently serving local transformers to meet consumer needs.
