Load testing begins on mini-hydroelectric plant in Gangelas, Angola

7 October 2014

Work to build a mini hydro-electric plant with a production capacity of 1.2 megawatts of electricity at the Gangelas dam in Angola, has been completed and is now waiting for the water level to rise to carry out load testing, according to Angolan news agency Angop.

The agency cited official João Delgado as saying that all work related to the construction, installation of turbines at the power station and power transmission lines had been completed and finishing touches were now being made.

Delgado also said that the water in the reservoir is not enough, given the current low flow of the river, and the team was waiting for the rainy season to begin to be able to conduct final tests.

Once it is fully operational, the power plant will consume 6.5 cubic meters of water per second. Its smallest group of generators has a capacity of 0.4 megawatts and consumes 2.4 cubic meters of water per second and the biggest (0.8 MW) consumes 4.1 cubic metres per second, so the reservoir must have at least 1.8 million cubic metres of water stored to drive the turbines.

Delgado stressed that the facility is guaranteed to operate for 50 years, if it is used appropriately and there are no unpredictable situations that could compromise the physical and technical integrity of the plant.

The Gangelas Dam, in Huila province, which was refurbished in 2009, has a reservoir capable of accumulating 3.5 million cubic metres of water and has two 24-kilometre channels and an irrigated area of 6 hectares of arable land. (macauhub/AO)
