Fire at Akosombo Substation Disrupts Power Across Ghana
On Thursday, April 25 2025, at approximately 2:01 p.m., a fire broke out at the Akosombo substation operated by the Ghana Grid Company Limited (GRIDCo) in the Eastern Region. The incident prompted an immediate shutdown of several transmission lines, leading to widespread power interruptions in parts of southern Ghana.
What Happened
GRIDCo’s official statement confirmed that the fire originated in auxiliary equipment within the substation yard. Emergency response teams, including the Ghana National Fire Service and GRIDCo’s technical crew, were dispatched within minutes and began containment efforts. According to the statement, the blaze was brought under control by 3:45 p.m., though equipment damage necessitated a thorough inspection before any re‑energising could occur.
Impact on Power Supply
The disruption affected the national grid’s ability to transmit electricity from the Akosombo and Kpong hydro‑electric plants to distribution networks managed by the Electricity Company of Ghana (ECG). ECG notified customers in the Volta and Oti regions that the outage stemmed from a “technical issue at the Akosombo Power Plant,” a direct consequence of the substation fire.
Areas experiencing loss of supply included:
- Sogakope
- Akatsi
- Yorkutikpo
- Dabala
- Adutor
- Torve
- Tordzinu
- Kpenu
- Ada
- Parts of Keta
- Adidome and surrounding communities
ECG’s notice emphasized that power would be restored once GRIDCo completed repairs and re‑synchronised the affected transmission lines.
Response and Restoration Efforts
GRIDCo reported that a comprehensive assessment is underway to determine the extent of equipment damage. Technical teams are:
- Inspecting transformers, circuit breakers, and control panels for heat‑related damage.
- Replacing compromised components with spare units from the national stockpile.
- Conducting insulation resistance tests to ensure safety before re‑energising.
- Coordinating with ECG to stage a phased restoration plan that minimises customer impact.
The utility urged the public to remain calm, noting that the situation is “under control” and that all feasible steps are being taken to normalise operations as quickly as possible.
Official Statements
“We kindly request the public to remain calm and reassure themselves that the situation is under control,”
ECG echoed this sentiment, adding that customers would receive regular updates via SMS and their customer service portals.
Looking Ahead
Industry analysts note that substation fires, while uncommon, can have cascading effects on national reliability. The Ghana Energy Commission has announced a review of fire‑prevention protocols at key grid facilities, with recommendations expected within the next 60 days. In the meantime, both GRIDCo and ECG continue to work around the clock to restore full power supply to the affected regions.
