GRIDCo, ECG temporarily shut down Mallam and Achimota substations as flooding disrupts power supply
The Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG) have temporarily shut down power supply from the Mallam and Achimota Primary Substations following severe flooding caused by heavy rains in parts of the Greater Accra Region.
In a joint press release issued on Monday, June 29, 2026, the two institutions said the precautionary shutdown was necessary to protect lives, prevent damage to critical electricity infrastructure, and ensure the safety of operational personnel.
According to GRIDCo and ECG, floodwaters have affected critical equipment at several substations, creating significant safety risks. They explained that the decision to switch off power supply was taken as a preventive measure until the floodwaters recede and engineers can safely assess the extent of the damage.
The utilities said they are closely monitoring the situation and conducting detailed assessments of the impact of the flooding on both the transmission and distribution networks. They warned that if heavy rains and flooding continue, additional power interruptions may occur in other affected areas where safety concerns arise.
GRIDCo and ECG urged the public to exercise extreme caution and immediately report any fallen electricity poles, exposed or fallen power lines, flooded electrical installations, or other electricity-related hazards to the nearest ECG office or through the company’s customer service channels.
They assured customers that every effort would be made to restore electricity supply as soon as weather conditions improve and it is safe to resume operations.
The two institutions also apologised for the inconvenience caused and thanked customers for their patience, cooperation, and understanding as emergency response teams work to protect critical power infrastructure and ensure public safety.
