EnergyProvisional: plant capacity not yet verified
Demand is growing faster than the capacity we can confirm.
Ghana's peak electricity demand reached a record 4,283 MW in 2025. This page tracks where it stands, where it is heading, and what could change the picture.

Peak demand: history and baseline projection
If demand keeps growing the way it has, annual peak reaches about 4,582 MW in 2026 and 6,147 MW by 2030 (likely range 5,573 to 6,780 MW). This is a trend projection, not a prediction of any single year.
Actual: 2025 Annual Report, GRIDCo, p. 26. Projection: baseline-0.2, constant-growth fit to 13 annual peaks (2013 to 2025); shaded band is an 80% prediction interval. Peaks before 2017 were held down by load shedding, so they show what was delivered, not what was wanted. A fit to only the steadier years since 2019 gives a lower path, about 5,911 MW in 2030. The projection excludes new demand sources such as EV charging. Capacity is not drawn because it has not been verified. In past tests, forecasts of this kind were off by about 3.0% on average, but there were only 15 test cases.
What changes the picture
Gas supply
Most of Ghana's power comes from thermal plants. When gas runs short, available capacity falls below what the plants are rated for.
Hydro levels
Akosombo, Bui and Kpong depend on rainfall. Dry years cut output and limit when plants can run.
New capacity
Plants and solar projects add supply, but projects slip. The model will test on-time and delayed cases.
Cooling and heat
Hotter evenings push air-conditioning load into the peak hours.
Electric vehicles
A small load today. The tool will show how much it would take for charging to matter, and how timing changes that.
Transmission and payments
Thin lines in some corridors and unpaid bills in the sector can cause cuts even when plants are available.
