Inauguration of EStor-Lux, the first high-capacity battery park, in Bastogne

The fleet of 480 lithium-ion battery modules, operational since December 9th, has an installed capacity of 10 MW and a storage capacity of 20 MWh, making it the largest operational battery site in the Benelux in terms of the storage capacity. It is also one of the first battery banks in Europe to offer long-term electrical recovery capacity (about 120 minutes, ie 2 to 4 times more than existing systems), allowing much more frequent and longer periods to ensure grid balancing , explained Bruno Vanderschueren , chairman of the board of the EStor-Lux consortium, which notably includes SRIW, Ackermans & van Haaren, CFE or even Idelux.

Beyond these technical details, this park makes it possible to meet the increased need for flexibility through renewable energies, “fluctuating and not perfectly predictable”. In this context, electric storage projects with batteries have the advantage over gas-fired production plants that they are more reactive (immediate activation), have no minimum load threshold for the provision of balancing power and emit no CO2.

According to its managers, since it was launched just over four months ago, EStor-Lux has made it possible to save around 40,000 tons of CO2 compared to the equivalent production of conventional gas-fired production plants.

“If we are to meet our climate goals, we need to move towards a flexible system to cope with the disruption in renewable energy. Batteries offer this opportunity,” said Federal Energy Minister Tinne Van der Straeten. “For too long, energy has been viewed as a problem to be solved rather than its incredible potential. But the world is changing. With this valuable tool for the energy transition, the Province of Luxembourg is an innovation ahead,” she added.

“This park is a beacon project for the environment and the economy. We are really in the middle of the energy transition, even though we know that there is still a long way to go before we reach 100% renewable energy,” added Regional Energy Minister Philippe Henry.

“In the face of a changing world, it is important that we do not remain immobile,” stressed Walloon Economy Minister Wily Borsus, paraphrasing Jacques Chirac. He welcomed the park’s success, “the result of a public-private partnership” and the impact of energy costs on businesses, and assured the project leaders “of the very strong mobilization of Walloon economic instruments”. “The region is also accessible through its tools dedicated to research,” he finally affirmed.
