There are currently approximately 25 power plants in Ghana with a combined installed capacity of about 5,615 MW. Historically, the Electricity Supply Industry (ESI) has been dominated by hydroelectricity from plants on the Volta, with The Volta River Authority (‘VRA’) owning over 80% of the total capacity.
However, following significant investment in conventional thermal generation capacity, as of 2024, Ghana's total installed generation capacity comprises 70% thermal generation and 28% hydropower generation.
The projected system peak demand for 2024 is 3,848 MW. However, this demand is expected to exceed 5,000 MW by the end of 2027.
