Ghana’s President John Mahama created a ministry of power on Saturday in a fresh bid to resolve a long-standing electricity crisis that has slowed economic growth and frustrated citizens with frequent power cuts.

According to a statement from the presidency, Kwabena Donkor, the chairman of parliament’s energy committee, will head the new ministry. Donkor was a former deputy energy minister.

Power production was previously overseen by the energy ministry, which was also responsible for managing Ghana’s upstream oil and gas sector.

Ghana generates much of its power from three hydro-electric dams that do not produce enough energy to satisfy an economy projected to grow at 6.9 percent this year.

It also imports natural gas from Nigeria via the West African Pipeline Company and will soon have offshore gas from the Jubilee field once a delayed pipeline and processing plant at Atuabo comes online.

On Friday, Mahama sacked the head of the state Electricity Company of Ghana, which is seen by experts as the least efficient of a chain of state power companies.
