The Electricity Company of Ghana (ECG) has begun a GH¢240 million transformer replacement and upgrade exercise across selected parts of Accra, in a move aimed at improving power supply reliability and meeting rising electricity demand in the capital.
The first phase of the project, approved by the Minister for Energy and Green Transition, Dr. John Abdulai Jinapor, commenced on Wednesday, April 8, 2026, at the Nmai Dzorn substation in the Adenta Municipality, and is expected to conclude by Friday, April 10, 2026.
The exercise covers 12 power transformers across six primary substations in Adenta, La, Teshie-Nungua, Nmai-Dzorn, Baatsonaa, and Lashibi. The transformers will be upgraded from 20/26 Mega Volt Ampere (MVA) to 30/39 MVA, significantly boosting load-handling capacity and reducing system overloads in these fast-growing communities. A subsequent phase at the Lashibi substation is scheduled to run from April 15 to April 17, 2026.
ECG General Manager in charge of Sub Transmission Operations, Francis Kofi Atsyatsya, who addressed the media ahead of the exercise, said the Nmai Dzorn area alone would see two new transformers installed at a cost of approximately GH¢34 million, fully funded by ECG. He added that the new equipment is expected to last more than 30 years with proper maintenance.
“We just want to assure customers in this enclave that they should be reassured,” he said. “Although there will be some impact of load management, we are very confident that within these two days, we will be able to complete this work and all of them will enjoy a reliable supply.”
To minimise disruption, ECG has grouped affected customers into four batches, with each group facing a planned six-hour outage during the work period rather than a total blackout. The company said detailed outage schedules have been prepared and will be published on its official communication platforms.
Acting Director of Communications Dr. Charles Nii Ayiku Ayiku said the upgrade would prevent transformer overloads, reduce frequent outages, and improve voltage stability across the affected communities. The broader programme is set to cover eight substations in the Greater Accra Region, with a separate transformer replacement also planned for Kumasi in the Ashanti Region.
