Akosombo Hydro Generation Station

Volta River Authority (VRA) management tables out plans to boost power generation at two of its power stations, namely Kpone Thermal Power Plant and Akosombo Hydro Generation Station.

Business Day Ghana reported that VRA intends to double the capacity of its Kpone Thermal Power Plant and has stated that water levels at Akosombo Hydro Generation Station have increased.

According to the director of Akosombo Hydro Generation Station, Richard Oppong-Mensah, the authority has minimised the level of generation at the Akosombo Dam to allow water levels to appreciate as the rainy season has started.

Media reported that Oppong-Mensah made the announcement last week during a tour at the hydropower plant.

Akosombo Hydro Generation Station

Figures from VRA indicated that as of Friday June 30, 2017, water levels were 240.42 feet (73.280 metres) about five feet more than it was at this same time last year – 235.50 feet (71.780 metres).

“We are expecting more increase, as the rain is at its peak especially from now till November. Actual rainfall will be in November,” Oppong-Mensah said.

The plant has installed and dependable capacities of 1,020MW and 900MW respectively; however, the Akosombo Hydro Generation Station is currently generating 353MW of power, media reported.

While Kpone Thermal Power Plant has an installed capacity of 220MW and a dependable capacity of 200MW.

Kpone Thermal Power Plant expansion

It is estimated that at least €153 million ($173 million) might be needed for the expansion works for the plant, which currently uses gas and distilled fuel oil (DFO) for its generation.

“We prefer running the thermal plant than the hydro plant, especially when the water level is very low. If you don’t manage the dam well, you destroy the turbines. When it [water levels] goes low, the effect becomes severe,” Oppong-Mensah noted.

According to media he explained that though the use of renewable energy is not that cheap, many people are now resorting to solar panels to reduce the high demand of energy on the national grid. Read more…

“Thermal runs on fuel while hydro runs on water. We have different sources of fuel to run our thermal plants. They are using heavy fuel other than gas,” Oppong-Mensah explained.
