Ghana’s electric vehicle market is growing quickly, but the shift away from petrol and diesel is creating a new problem: how to keep the country’s power grid strong enough to handle the extra demand.

The government sees electric vehicles as a way for households and businesses to cut fuel costs. But as more charging stations appear, especially fast-charging facilities, the electricity network is coming under pressure in some areas.

Energy and Green Transition Minister John Abdulai Jinapor raised the concern at the 2026 Future of Energy Conference in Accra on Aug. 25. He said Ghana must make sure the growth of electric mobility does not come at the expense of reliable electricity for factories, mines, data centers and other businesses.

Ghana is already seeing strong interest in EVs, with lower running costs helping drive adoption. Jinapor said government research shows EV users can save about 40% on fuel costs, giving consumers a clear financial reason to switch.

Fast charging puts transformers under pressure

The biggest concern is fast charging. New systems can charge some vehicles in five to 10 minutes, but that speed comes with a heavy electricity load over a short period.

Jinapor said some transformers have failed after charging stations were connected to local networks. He said the government wants charging infrastructure planned alongside grid upgrades rather than added first and addressed later.

Ghana’s power demand is already rising

The timing adds to a wider challenge for Ghana’s electricity sector. The Energy Commission expects peak power demand to reach 4,581 megawatts in December 2026, up 7% from 2025, while electricity consumption is forecast at 28,992 gigawatt-hours.

The commission also expects reserve margins to remain below the recommended 18% level for much of the year. That leaves less room for unexpected outages or sudden increases in demand, making careful planning of EV charging infrastructure more important.

Government moves to control EV charging growth

Legislation before Parliament would require operators to obtain approval from the Energy Commission before setting up charging stations. The approval process would allow authorities to assess grid capacity and determine where transformers or other upgrades are needed.

The Energy Commission, Ghana’s technical regulator for the energy sector, already advises individuals, companies and institutions to seek approval before installing EV charging or battery-swap facilities. Its rules are intended to ensure the infrastructure meets safety, technical and operating standards.

For Ghana, the EV shift is no longer only a transport story. As more vehicles move to electricity, the country must also make sure its power network can keep up without disrupting the industries and businesses that depend on reliable electricity.
