Tesla's energy storage business is planting a major flag in Europe. Construction has officially begun on a $116 million Megapack battery facility in Kluisbergen (Ruien), Belgium — one of the largest grid-scale storage projects the company has undertaken on the continent.
The facility will deploy 180 Megapack units to deliver 700MWh of total energy storage capacity. According to verified reports, the project features Tesla's latest Megapack 3 technology and is being developed by Belgian energy firm Storm. Testing and commissioning are expected to wrap up by the end of 2027.
To put the scale in context, 700MWh is enough stored energy to power hundreds of thousands of homes for several hours during peak demand — exactly the kind of buffer that grid operators across Europe are scrambling to build as renewable generation capacity outpaces storage infrastructure. Projects like this one sit at the intersection of Tesla's two core businesses: it generates revenue for Tesla Energy while directly supporting the clean grid that makes EV ownership more meaningful.
Tesla Energy has been a quietly accelerating part of the company's story. Megapack deployments have grown significantly year over year, and large contracted projects like the Belgium facility provide predictable revenue that smooths out the quarter-to-quarter volatility of vehicle deliveries. With commissioning still 18 months away, this project will be a line item worth watching when Tesla reports energy storage deployment figures through 2026 and into 2027.
