The National Electricity Corp of Sudan has signed a contract with Voith Siemens Hydro Power Generation for the modernisation of the Kashm El Girba power station. The plant, which is on the river Atbara, a tributary of the Nile, has been supplying power and water for irrigation for 35 years. Under the deal, worth E4 million, Voith Siemens will provide new turbine runners, a digital governor and other major components for two Kaplan turbines. Upon completion, the plant should produce 20 per cent more energy that previously. Voith Siemens is already refurbishing three pump turbines at the same plant.
