GRIDCo, ECG shut down Mallam and Achimota substations as floods threaten power infrastructure
The Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG) have temporarily suspended power supply from the Mallam and Achimota primary substations after severe flooding compromised critical electricity infrastructure in parts of the Greater Accra Region.
The two power utilities said the emergency shutdown was implemented as a precautionary measure to protect lives, preserve vital equipment, and prevent extensive damage to the national electricity network following the heavy rains.
In a joint statement issued on Monday, the utilities explained that rising floodwaters had affected key transmission and distribution facilities, creating significant safety risks for both personnel and electrical installations.
“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.
The utilities added that suspending electricity supply was the safest course of action until conditions improve.
“To safeguard lives, protect property, and prevent damage to the electricity network, GRIDCo and ECG have taken the decision to temporarily switch off power supply from the affected substations until conditions are safe for restoration.”
GRIDCo and ECG said engineers are continuously monitoring the affected facilities and conducting detailed assessments to determine the extent of the damage caused by the flooding.
They also cautioned that additional power interruptions could occur in other flood affected areas if safety concerns arise.
“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 utilities urged residents to remain vigilant and promptly report fallen electricity poles, exposed or damaged power lines, flooded electrical installations, and any other electricity related hazards to the nearest ECG office or through the company's customer service channels.
According to the statement, timely reporting of such hazards will enable emergency teams to respond quickly and minimise risks to the public.
GRIDCo and ECG apologised for the inconvenience caused by the temporary outages and assured customers that power would be restored as soon as weather conditions improve and engineers confirm that it is safe to resume operations.
