Storm, together with I4B (‘The Belgian Infrastructure Fund’), PMV, TINC and a banking syndicate, is investing €330 million in two large-scale battery parks in Ruien and Langerlo.
The company said the projects will have a capacity of 200MW in Ruien and 100MW in Langerlo, with storage capacities of 800MWh and 400MWh respectively.
Storm added that the developments will significantly increase the available large-scale battery capacity in Belgium.
The Ruien project is being built on the site of a former coal-fired power plant and will consist of 180 lithium-ion battery units supplied and installed by Tesla.
The Langerlo project is located in the port of Genk-Zuid and will also use lithium-ion batteries supplied and installed by Tesla.
Construction has already started on both projects, with commissioning planned for autumn 2027 in Ruien and summer 2027 in Langerlo.
TINC, PMV and I4B are contributing capital alongside Storm, with project financing provided by a banking consortium including Belfius, ING, KBC Bank, Rabobank, Santander, Societe Generale and Triodos Bank.
“With these projects, we are taking an important step in the development of flexible energy infrastructure in our country,” said Jan Caerts, chief executive of Storm.
“Large-scale battery storage is essential to keep the electricity system stable and to enable the further integration of renewable energy.”
