In the 1980s and 1990s Ghana experienced strong economic growth that brought with it a large increase in demand for energy, however, Ghana suffered power shortages because it had not invested heavily in its energy infrastructure, it did not have the capacity to keep up with the growth in energy demand.
Rolling blackouts from 1998-2000 decreased output from the industrial and service sectors and, as a result, the economy suffered. 2007-2009 saw another intense period of electricity rationing whilst as recently as March 2012, the majority supplier of electricity in Ghana, the Volta River Authority (VRA) announced that there will be further rolling blackouts all around the country until July 2012 at the very earliest.
Electric power constitutes only about 11% of Ghana’s energy supply mix. Access to electricity in Ghana is, however, 45% compared to an average of 20% for West Africa.
A little over half of Ghana’s energy is obtained from hydro sources, whilst the remaining is obtained from thermal. The supply of electric power to Ghana is obtained primarily from hydropower generated at the Akosombo and Kpong dams and two thermal plants (light crude oil fired) near Takoradi in Southern Ghana.
