A campaign to renovate the hydroelectric power stations of Bervercé (9MW) and Heid de Goreux (8MW) has just started. The Robertville dam upstream from Bervercé is also part of this work program. Dating back to 1930, these facilities were pioneers in the production of renewable and local energy in Belgium. This work will enable them to contribute to a carbon-neutral future for decades to come.
The country’s leading producer of renewable energy with 836 MW of installed capacity, ENGIE produces renewable energy from various energy sources, including hydropower. ENGIE operates 22 MW of hydroelectric installations spread over 8 sites and also has extensive experience in hydroelectric infrastructure with the Coo pumped storage plant (1080MW) in operation since 1972.
The cost of renovating the Bervercé, Heid de Goreux and Robertville dam power stations amount to 15 million euros in total. These will allow these infrastructures to continue to produce renewable and local energy each year. Their production of 48 GWh per year is equivalent to the annual consumption of just over 16,500 households. It avoids the emission of 19,200 tonnes of CO 2 per year, the equivalent of the annual emissions of 9,600 personal diesel cars.
At the Bervercé hydroelectric power station, two of the three turbines will be replaced. Maintenance and repair work on the external facing of the Robertville dam upstream of the power plant will also be carried out. The end date of this work is scheduled for September 2022. In 2023, anti-corrosion treatment work on the pipe connecting the Robertville dam to the Bervercé power plant will also be undertaken. This 5 km pipe connects the dam to the power plant downstream over a drop of 150 meters. All of these installations are supplied by the waters of the Warche. Bervercé is a so-called “accumulation” power plant because its upstream Robertville dam allows water to be stored in the event of excess electricity on the network and to turbinate the water if necessary. The Robertville dam also plays an important local role: with its 8 million cubic meters in reserve, it supplies the town of Malmédy with mains water and offers a popular nautical and fishing area. It also regulates the flow of the Warche and thus prevents flooding.
At the Heid de Goreux power station, the two turbines will be replaced and a new connection to the distribution network will be made. The replacement of the turbines follows the flooding of the power station in 2018. The power station is supplied by the Amblève via an underground pipe running 3.5 km over a drop of 40 meters. This pipe is connected upstream to a control reservoir at Lorcé. The power station is said to be “run-of-river” because it turbines the flow of the river without a storage tank upstream. The completion date is scheduled for summer 2022.
Cedric Osterrieth, CEO ENGIE Generation Europe: “These hydroelectric plants are part of the energy history of their region and our country. They have been producing renewable and local energy for nearly a century. Thanks to the significant investments of ENGIE and its expertise as the leading green producer, they are more than ever part of the country’s energy future, a future in which ENGIE intends to be the leader in the transition to carbon neutrality”.
