Tesla Inc. is strengthening its foothold in Europe’s energy sector with an $87 million (€85 million) deal to supply battery storage in Belgium. The project will deploy Tesla’s Megapack batteries, delivering 75 megawatts (MW) of power and 300 megawatt-hours (MWh) of storage capacity—enough to stabilize Belgium’s fast-growing renewable grid.
The system, operated by Energy Solutions Group, will be installed in Harmignies, a former cement factory now repurposed for clean energy. Cement production accounts for 8% of global CO₂ emissions, making the transformation symbolic of the shift to sustainable solutions. “This project is a critical step in balancing renewable energy supply and demand,” said an Energy Solutions spokesperson.
Belgium’s Clean Energy Acceleration
Belgium is rapidly expanding its clean energy infrastructure, investing heavily in offshore wind and battery storage. The country is constructing Princess Elisabeth Island, an “energy island” designed to integrate North Sea wind farms into the power grid.
Tesla’s latest deal follows Belgium’s largest battery energy storage system (BESS), activated in October 2024 in Wallonia. That project, featuring 40 Tesla Megapacks with a capacity of 50 MW and 100 MWh, reinforced Belgium’s commitment to grid reliability.
Tesla Bets Big on Battery Storage
Tesla is scaling up Megapack production as demand for large-scale energy storage surges. Each Megapack unit stores 3.9 MWh—enough to power 3,600 homes for an hour. Tesla’s California Megapack factory recently hit its 10,000th unit milestone, with annual production targets of 10,000 units. A Shanghai Megapack factory is also ramping up, aiming for the same capacity.
With governments worldwide investing in grid-scale storage, Tesla is positioning itself at the center of the clean energy transition. Belgium’s latest deal signals the growing role of battery technology in securing a stable renewable power supply.
