Ghana announces plans to build more mini hydropower plants

Ghana may build more mini hydropower plants across the country, to increase power supply from the national grid, according to the Ghana News Agency.

The agency recently reported that Mr. John Peter Amewu, Minister for Energy, said the country was migrating to mini hydro power plants as a source of power supply for communities when the national grid was off. Amewu is reported to have said this when he inspected completed works on the construction of civil structures of a 42-kW Tsatsadu mini hydro power project at Alavanyo-Abehenease in the Volta Region. The Tsatsadu waterfall is a tourist site.

He said construction of more mini hydropower plants would make renewable energy become a “sizeable proportion” of the country’s energy mix. He also said the power plants would also serve as a learning center for students to gain more knowledge on the generation of mini hydro power in the subregion.

The construction of the mini hydro power plant at Alavanyo-Abehenease on the Tsatsadu River started in 2005 but stalled before resuming in 2017. It is estimated at $400,000 and, when completed, will be the first in Ghana.

Alex Okae-Acheampong, design manager at Bui Power Authority and project manager of the run-of-river Tsatsadu Generating Station, said generation from the plant was estimated for seven months in a year after, with the rest of the months used for maintenance works.

Fred Oware, chief executive officer of Bui Power Authority, said the authority is looking for other waterfalls in the region that may be viable for the construction of a hydropower plant.
