Case Studies
The BESS has already started commercial operations and the project is thus actively contributing to improving the stability of the Belgian high-voltage (HV) grid as well as operating in the short-term electricity markets. The plant is located on the site of a former 800 MW coal fired power plant and therefore constitutes a good example of how to drive the energy transition forward by embedding flexible BESS assets in a market with an already elevated penetration of renewables in the production mix. The project also highlights the importance of battery energy storage systems for the energy transition throughout Europe, as a decisive part of a future integrated European energy system.
The 25 MW/100 MWh grid-scale BESS in Ruien is one of the largest connected to the Belgian HV grid as well as one of the first four-hour long duration BESS units in the EU. It is one of the first projects of this type in Europe that meets all relevant ESG standards and has a strong focus on sustainable construction and operation.
