Ghana’s Power Crisis: Why Another Major Blackout Has Raised Fresh Questions

For theGhana’s Power Crisis: Why Another Major Blackout Has Raised Fresh Questions time in less than a month, many Ghanaians woke up to an unexpected power outage.

On Thursday, August 20, parts of the country were plunged into darkness after a major fault developed on the Akosombo–Volta transmission line.

GRIDCo said the fault occurred at about 4:30 a.m. and triggered the automatic shutdown of the Akosombo generating units and some thermal plants. The shutdown was part of the national grid’s protection system, which is designed to prevent further damage and protect the stability of the network.

Power has since been restored to affected areas, but the latest incident has left a bigger question hanging in the air:

Why are major power disruptions happening again?

It is the second major disruption in three weeks

The timing of the latest outage is what has particularly worried many people.

On July 29, Ghana experienced another widespread power system disturbance that affected several parts of the country.

Less than three weeks later, another major disruption occurred.

GRIDCo says the two incidents were linked to technical problems affecting the transmission system. The company has also indicated that investigations are underway.

For households and businesses that depend on a reliable electricity supply, however, repeated interruptions are more than just a technical matter.

A single unexpected outage can mean spoiled food, interrupted work, cancelled business transactions, damaged equipment and additional operating costs.

For small businesses in particular, the impact can be immediate.

What happened on Thursday?

According to GRIDCo, the latest incident began with a fault on the Akosombo–Volta transmission line.

The fault caused several generating units to trip automatically. Some thermal generating plants were also affected.

These automatic protection systems are designed to respond when the grid detects a serious disturbance. In this case, they helped protect the wider transmission system from potentially more serious damage.

GRIDCo engineers then isolated the affected line and began restoring the system.

By Friday, the company said electricity supply had been fully restored to all affected areas and that grid-strengthening measures were continuing.

So, from GRIDCo’s perspective, the response worked.

But that has not ended the questions.

Energy experts want more answers

The Africa Sustainable Energy Centre (ASEC) says restoring power should not be the end of the matter.

The organisation has called on GRIDCo to publish a comprehensive technical report explaining what caused the recent disturbances, whether existing protection and redundancy arrangements are adequate and what will be done to prevent similar incidents.

Energy analyst Justice Ohene-Akoto has also accused GRIDCo of not providing enough information about the causes of the recurring outages.

His concern is essentially about transparency: if the public is being asked to accept repeated disruptions, people should also be given a clear explanation of what is going wrong and what is being done about it.

The Institute for Energy Security has separately called for the release of the technical findings from the July 29 outage, particularly following the latest incident.

Is Ghana returning to “Dumsor”?

That is the question many people are already asking.

But it would be premature to describe the current situation as a return to the prolonged nationwide power crisis popularly known as Dumsor.

The latest outages have been attributed to specific system disturbances and transmission problems, rather than an officially declared nationwide power rationing programme.

Still, the concern is understandable.

Ghanaians remember how disruptive prolonged power instability became, particularly for businesses, hospitals, schools, households and industries.

That is why repeated major disturbances naturally bring back uncomfortable memories.

The Akosombo system remains a concern

Energy Minister John Jinapor has appealed to Ghanaians to remain calm following the latest outage.

He explained that ongoing work on the Akosombo transmission system is part of the wider challenge and indicated that the permanent works are expected to be completed next month.

That timeline will therefore be closely watched.

If the permanent system is completed as expected, one important question will be whether the changes provide enough resilience to prevent a repeat of the recent disruptions.

The real issue is reliability

For ordinary Ghanaians, the technical language surrounding transmission lines, protection systems and generating units can sometimes feel distant.

The concern is much simpler:

Can the lights stay on?

Businesses need electricity to operate. Students need it to study. Hospitals and other essential services need dependable power. Households also need stability to plan their daily lives.

That makes reliability just as important as restoring power after a failure.

The latest developments suggest that Ghana's energy authorities have been able to restore the system after major disturbances.

The bigger test now is whether they can make the system strong enough to withstand those disturbances in the first place.

For that reason, the calls for a detailed technical report deserve attention.

Ghanaians do not simply need to know that the lights have come back on.

They also need to understand why they went off, what caused the problem and what is being done to make sure it does not happen again.

Global Pulse GH will continue to monitor developments in Ghana's power sector and provide updates as GRIDCo and the energy authorities release further information.
