Kpong Hydro Plant

Kpong hydroelectric project represents the third stage in the development of the Volta River, commonly known as the Volta River Project. The first stage began in 1961 when the Volta River was established and work started on the Akosombo dam and power station. By September 1965 the first power was flowing from Akosombo, marking an important step in the economic development of the newly formed Republic of Ghana.
The Kpong generating station was completed in 1982. The total installed capacity at Kpong is about 160 MW. However, if all four units at Kpong are running, there is a rise in tail water elevation, which limits the output of the generation to about 148 MW.

The combined Akosombo/Kpong system has an installed capacity of 1,180 MW. The Kpong head pond has minimal storage capacity and is therefore operated in tandem with Akosombo as a run-of-the-river plant to optimize water use from the Volta Lake. The joint firm energy output from the Akosombo/Kpong hydroelectric development is about 4,800 GWh. Meanwhile the Long-Term Average (LTA) capability of the two plants is about 6,100 GWh.

The other Key events in the project were:

  • August 12, 1976 - Tenders for major Kpong Project (Civil works called);
  • August 24, 1977 - Contracts awarded to Impregilo-Recchi;
  • November 30, 1977 - Ground breaking Ceremony;
  • December 15, 1982 - All Generating Units commissioned;
  • July 1, 1982 - Project officially inaugurated by the Head of State.
