There are currently approximately 21 power plants in Ghana with a combined installed capacity of about 5,083 MW Historically, the Electricity Supply Industry (ESI) has been dominated by hydroelectricity from run-of-river 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, by the end of 2010, Ghana's total installed generation capacity was almost equally divided between these two power sources.
The projected system peak demand for 2019 is 2,665.68 MW. However, demand is expected to exceed 5000MW at a rate of 18% reserve margin by 2024.
