Storm raises €330 million for the construction of two large-scale batteries

25/3/26

Storm is investing €330 million alongside I4B – The Belgian Infrastructure Fund (“I4B”), PMV, TINC and a banking syndicate in two large-scale battery parks in Ruien (Kluisbergen) and Langerlo (Genk).

The battery parks will have a capacity of 200 MW in Ruien and 100 MW in Langerlo, with respective storage capacities of 800 MWh and 400 MWh. In doing so, Storm is increasing the available large-scale battery capacity in Belgium substantially.

In Ruien (Kluisbergen), the project is being built on the site of a former coal-fired power station. It covers an area of more than three hectares and will consist of 180 units with lithium-ion batteries, supplied and installed by Tesla. This will make it one of the largest battery parks in Europe. Commissioning is scheduled for autumn 2027.

The battery park in Langerlo (Genk) is being built on a site of almost two hectares in the port of Genk-South. The park will be connected to the transmission grid via the high-voltage connection of a former coal-fired power station. Here too, Storm is using lithium-ion batteries supplied and installed by Tesla. Completion of this project is expected in the summer of 2027.

For both of these projects, the construction phase has already begun.

TINC, the Flemish investment company PMV and I4B are providing the equity capital for the battery parks together with Storm. Project financing is being provided by a banking consortium comprising Belfius, ING, KBC Bank, Rabobank, Santander, Societe Generale and Triodos Bank. Santander Corporate & Investment Banking acted as exclusive financial advisor to Storm for the equity capital raise and debt advisory of the combined projects.

“With these projects, we are taking an important step in the development of flexible energy infrastructure in our country,” says Jan Caerts, CEO of Storm. “Large-scale battery storage is essential for maintaining the stability of the electricity system and enabling the further integration of renewable energy. This is also a transformative step for Storm itself. Over the past 15 years we have developed more than sixty wind turbines in Belgium. By adding flexible storage capacity to our portfolio, we will eventually create a well-balanced sustainable energy supply.”

Storm will develop even more energy storage capacity in the coming years, including a ready to build project in Zeebrugge (100 MW/400 MWh). The company also has dozens of new wind turbines under construction or in development, both in Flanders and Wallonia.
