Left: Commissioned in 1969, the Gebidem dam in Switzerland, impounds the water of the Aletsch glacier, one of the largest in the Alps. At a depth of 750 metres, the hydropower station in Bitsch uses the water to generate electricity. The plant consists of three Pelton turbines and has a total capacity of 340 MW. The plant can produce an average annual output of up to 564 GWh per year
representative. Together with GE Hydro Solutions, the three partners are committed to deliver the highest engineering and design quality, to ensure continuity of operation, and to organize project integration and management. As the sixth largest hydropower plant in Switzerland, the hydropower plant Bitsch plays a major role in the Swiss energy supply. This upgrade of the power plant capacity underlines the role of hydropower as the major source of renewable energy in Switzerland. “We are delighted to support Electra-Massa SA in their efforts to produce sustainable electricity with a higher level of reliability to meet local demand,” said Pascal Radue, President and CEO of GE’s Hydro Solutions. “We appreciate their confidence and will work to ensure that the customized design of the future generators will help improve the performance of the power station. Most importantly, Electra-Massa SA will be able to produce sustainable electricity with a higher flexibility to meet the local demand. We are proud to be part of this project which confirms the critical role of hydropower in the Switzerland’s energy production.” GE Hydro Solutions will be responsible for the design studies, the engineering, the manufacturing and the delivery of the two generators. Once the generators are delivered, GE Hydro Solutions will be in charge of the erection and the commissioning of the new equipment. The first modernized Bitsch unit is expected to be commissioned in August 2024, and the last one is expected to come online in 2025.
Jebba plant, Nigeria Andritz recently announced it is to modernise a
second generating unit at the Jebba hydroelectric power plant on the Niger River. The technology group was again contracted by Mainstream Energy Solutions Limited following an order received in January 2021 to modernize the first unit 2G6.
Under the new deal, Andritz’s scope of supply and services comprises the entire electro-mechanical and hydro-mechanical equipment for unit 2G5, including a 96.4MW turbine, a 103 MVA generator and accessory equipment, as well as the intake gate. Commissioning

has been scheduled for beginning of 2024. Originally commissioned in 1985, the Jebba
hydroelectric power plant is located in the North Central zone of Nigeria, about 100km downstream of the Kainji Hydroelectric Power Plant. It is equipped with six 96.4MW turbines and has a total generating capacity of 578.4MW. The objectives of the general rehabilitation program
are to extend the equipment service life for the next 40 years, improve reliability, and ensure compliance of the frequency and voltage control with the national grid code. The new equipment will repower the plant, boost the energy production of Nigeria, and provide much-needed energy to the people of the country. ●
