Renewables developer and IPP Storm has secured project finance for two large-scale BESS projects in Ruien and Langerlo, Belgium.

Storm, investors I4B (The Belgian Infrastructure Fund), PMV, TINC and a banking syndicate are collectively investing €330 million (US$382 million) in the two battery energy storage system (BESS) projects, which total 300MW/1,200MWh of capacity.

The Ruien project is 200MW/800MWh, on the site of a former coal-fired power station, and Langerlo is 100MW/400MWh, and construction on both projects is underway.

Tesla is providing the BESS units, with Ruien scheduled for commissioning in autumn 2027 and Langerlo for summer 2027.

One commenter on the company’s LinkedIn post announcing the news today (25 March) claimed the projects will use the latest tech from Tesla, including its Megapack 3 and Megablock.

Renders of both projects, once complete, are below.

TINC is providing €23 million of the equity portion of the financing, while debt is provided by a banking consortium comprising Belfius, ING, KBC Bank, Rabobank, Santander, Société Générale and Triodos Bank.

Storm has primarily deployed wind in the past, but these projects, plus a third ready-to-build (RTB) 100MW/400MWh BESS in Zeebrugge, mark its entry into energy storage.

Alongside the UK and Germany, Belgium has been one of the early-mover markets in Europe, with plentiful opportunities in energy trading, ancillary services, the capacity market (CM) and a favourable regulatory environment.

Multi-hundred-megawatt-hour projects have launched construction, secured offtake or BESS supply in the past year (or all three). These include projects from operators Apsiravi, I4B (also an investor in Storm’s), HybriX Energy, Engie, Giga Storage. See all Belgium coverage here.
