Energy Ministry confirms full shutdown of Akosombo dam after substation inferno

The Ministry of Energy has confirmed that the Akosombo Dam has been completely shut down following a devastating fire at the Ghana Grid Company (GRIDCo) substation in Akosombo, a development that has triggered widespread power outages across the country. The shutdown represents a major disruption to Ghana’s electricity supply chain, as the Akosombo Dam is one of the country’s primary sources of power generation, supplying a significant portion of the national grid.

Ministry spokesperson Richmond Rockson said the decision to shut down the facility was unavoidable after critical infrastructure was destroyed in the blaze. He noted that the scale of the destruction posed serious safety risks and made continued operations impossible under current conditions.

“The switch yard, which is at the Akosombo Substation, is completely burnt down and it is not salvageable. The primary control room for the switch yard is completely gone,” he said. The switch yard is a vital component of the power transmission system, responsible for directing electricity from generation sources into the grid, making its destruction particularly severe.

According to him, the extent of the damage made it impossible to safely continue operations at one of Ghana’s most important power generation facilities. He explained that engineers and officials who visited the site struggled to even access parts of the destroyed installation due to debris, heat damage, and safety concerns.

“It was even difficult for us to walk there when we got there to assess the situation,” he added. This highlights the intensity of the fire and the level of structural damage caused to the facility.

The fire reportedly broke out around 2:01 p.m. on Thursday, April 23, engulfing the GRIDCo substation, which plays a key role in transmitting electricity from the Akosombo Dam to the national grid. The substation acts as a central hub for power distribution, meaning any disruption there has immediate nationwide consequences.

The Ministry says the shutdown of the dam has had a significant impact on power supply nationwide, given Akosombo’s central role in Ghana’s electricity generation mix. The loss of power from the dam is expected to increase pressure on other generation sources, including thermal plants, which may struggle to fully compensate for the deficit in the short term.

Rockson stressed that the shutdown was a necessary safety measure following the destruction of the switch system, which has rendered operations in the area inoperable for now. He indicated that restoring operations would depend on rebuilding critical infrastructure and ensuring all safety standards are met.

He spoke on the Citi Breakfast Show on Monday, April 27, where he provided updates on the situation and reassured the public that efforts were underway to address the crisis.

Investigations are expected to continue into the cause of the fire, while restoration works are likely to begin once technical assessments are completed. Authorities are also expected to review safety protocols and infrastructure resilience to prevent similar incidents in the future. Energy sector stakeholders may need to consider additional investments in grid protection systems and emergency response mechanisms to enhance reliability.
