The Electricity Company of Ghana (ECG) has started the installation of two high-capacity power transformers at the Ridge Bulk Supply Point in Kumasi, a major step to reinforce supply reliability across the metropolis.
The project replaces two existing 20/26MVA transformers with upgraded 30/39MVA units, significantly boosting station capacity and easing pressure on the network.
This upgrade directly addresses recent intermittent outages and voltage fluctuations in parts of Kumasi, which have been driven by rising demand rather than generation shortfalls.
ECG’s Acting Managing Director has emphasized the strategic importance of the project:
“Kumasi is expanding, and electricity demand is rising with it. This upgrade ensures our infrastructure keeps pace so customers can enjoy more stable and reliable power.”
On site, Manager, Substation & Switchgear Maintenance for Ashanti Sub-Transmission described the work as both urgent and complex: “The existing transformers are under pressure. These new units give the system breathing room and improve overall stability.”
Teams from Accra and Ashantii Sub-Transmission Divisions are jointly coordinating the installation. The transformers are scheduled to be installed by May 6 and 7, 2026, with energization planned shortly after.
Installation schedule:
- May 6: Replace and energize Transformer 2
- May 7: Replace and energize Transformer 1
Outage details
To ensure smooth safety operations, ECG will implement controlled outages:
- Dates: May 6 and May 7
- Time: 9:00 AM – 3:00 PM
There will be temporary shutdown of sections of the 33kV network and managed load distribution on 11kV feeders.
ECG assures customers that the interruptions are carefully planned and limited in duration.
”We understand the inconvenience, but these are necessary steps to deliver a more reliable system,” added Collins Manu, Communications Officer of Ashanti Sub-Transmission.
