The Ghana Grid Company Limited (GRIDCo) and the Electricity Company of Ghana (ECG) have announced the temporary shutdown of 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 measure was necessary to protect public safety after floodwaters affected critical electricity infrastructure.
According to the statement, the flooding posed significant risks to electrical equipment and operational personnel, making it unsafe to continue supplying power from the affected facilities.

“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.
GRIDCo and ECG explained that power supply from the affected substations would remain suspended until conditions are safe for restoration.
The two institutions said they are continuously monitoring the situation and conducting detailed assessments of the impact of the flooding on the transmission and distribution network.
They also cautioned that if the heavy rains and flooding persist, electricity supply could be temporarily interrupted in other affected areas where necessary as a precautionary measure.
The utilities appealed to customers and the general public for patience and understanding while engineers work to ensure the safe restoration of electricity services.
