The Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG) have temporarily shut down the Mallam and Achimota primary substations following severe flooding caused by heavy rains in parts of the Greater Accra Region, warning that additional power interruptions may occur if weather conditions worsen.
The statement was jointly issued on June 29, 2026, by the Corporate Communications Section of GRIDCo and the Communications Directorate of ECG.
The two power utilities said the precautionary shutdown was necessary after floodwaters affected critical electricity infrastructure, posing significant risks to electrical equipment and operational personnel.
“The precautionary shutdown became necessary because the flooding has affected critical power infrastructure at a number of substations, posing significant risks to both electrical equipment and operational personnel,” the statement said.
It added that the decision was taken “to safeguard lives, protect property, and prevent damage to the electricity network” until conditions are safe for power restoration.
According to the statement, GRIDCo and ECG are continuously monitoring the situation and conducting detailed assessments of the impact of the flooding on both the transmission and distribution networks.
The utilities cautioned that as the heavy rains and flooding continue, electricity supply could be temporarily interrupted in other affected areas where safety risks are identified.
“As the heavy rains and flooding persist, the public is advised that power supply may be temporarily interrupted in other affected areas, where necessary, as a precautionary measure to protect lives, property, and critical electricity infrastructure whenever safety risks are identified,” the statement noted.
The public has also been urged to exercise extreme caution and immediately report fallen electricity poles, exposed or fallen power lines, flooded electrical installations, and other electricity-related hazards to the nearest ECG office or through the company’s customer service channels.
GRIDCo and ECG apologised for the inconvenience caused, assuring customers that every effort would be made to restore electricity supply as soon as weather conditions improve and it is safe to do so.
