The Ashanti Sub-transmission of Electricity Company of Ghana (ECG) has had an inter-sector arrangement with the Ghana Grid Company (GRIDCo) to boost supply capacity to meet the growing demand for electricity in The mutual agreement was reached at a meeting held at GRIDCo’s headquarters at Anwomaso .
The arrangement of the agreement after the meeting is to install a 145MVA power transformer between GRIDCo and ECG Bulk Supply Points to replace one of the three 50MVA transformers to increase the installed capacity to meet the growing demand in load, especially during the peak period which is between(7pm and 11 pm).
Before this capacity-building arrangement, the 50MVA transformers at Anwomaso Bulk Such ply Point sometimes stretched to their maximum loading capacity because of the increase in demand at peak times. But with the installation of the 145MVA transformer, the total installed capacity would be 245MVA instead of the existing 150MVA (that is, 3 times 50MVA transformers).
The two stakeholders believe this will help improve supply capacity and reliability in the region.Similarly, at the meeting, there was an agreement to upgrade the Obuasi and Konongo Substations to 50/66 MVA transformers to meet the growing industrial needs in the enclaves and improve supply reliability in the areas.
There were also discussions to send another 145MAV to Ridge BSP shortly to increase the supply capacity of the Station, and the region as a whole.After the discussions between the two companies, there was a site visit to assess where the 145 MVA transformer could be installed. Ing. Peter Kofi Fletcher, General Manager for Ashanti Sub-transmission, and his team discussed with the GRIDCo team on-site to find a suitable location for the new transformer to reduce the material cost of cable laying and other civil works.
Currently, the region has two Bulk Supply Points, Anwomaso and Ridge that supply high-voltage power to other primary substations that feed the local transformers to serve consumers.
