The Electricity Company of Ghana (ECG) has announced a major transformer replacement and upgrade project at the Batsonaa Primary Substation, even as engineers continue to battle widespread network faults that plunged scores of communities across the Ashanti, Tema, and Western Regions into darkness on Friday, May 22, 2026.

In a press release issued on Friday, the ECG disclosed that the upgrade forms part of the government's Transformer Replacement and Upgrade Programme, designed to improve the reliability of power supply and reduce system overloads within the distribution network.

The project follows the successful completion of similar upgrade works at the Adenta, Nmai Dzorm, Lashibi, Teshie-Nungua, and Kumasi Ridge Primary Substations.

Batsonaa upgrade schedule

The ECG will replace the existing 20/26 MVA power transformer at the Batsonaa Substation with a higher-capacity 30/39 MVA transformer.

The exercise is scheduled to take place from Sunday, May 31, to Monday, June 1, 2026, with phased power interruptions lasting approximately six hours per affected group.

According to the detailed outage schedule, Group A, covering Mawako Fast Food, Alfa Trading, Goil Filling Station, Spintex Plaza, Coca Cola Factory, Kasapreko, China Mall, and other industries along the Spintex Road, will experience outages from 6:00 am to 12:00 pm on Sunday, May 31, and again from 12:00 am to 6:00 am on Monday, 1st June.
