Tesla has begun construction of a 2.8 GWh Megapack battery facility in Belgium, a major European energy storage project using its new Megablock architecture.
Tesla has broken ground on a $650 million megawatt‑hour‑scale battery plant in Belgium, marking the company’s largest single‑site energy‑storage project in Europe.
Megapack megawatt‑hour capacity
The new facility will host 2.8 GWh of Megapack units, enough to power roughly 1 million homes for a full day or provide grid‑balancing services across the region.
Tesla’s Megablock architecture, introduced earlier this year, integrates multiple Megapack modules into a modular, pre‑engineered block that speeds construction and reduces on‑site labor.
Strategic location in Belgium
The plant is sited near the town of Hasselt in the Flemish region, close to existing transmission infrastructure and major renewable‑energy hubs in the Netherlands and Germany.
Belgium’s government has pledged to double its renewable‑energy capacity by 2030, and the Megapack site is expected to support that goal by storing excess wind and solar generation.
Economic and job impact
Tesla estimates the project will create 300 direct jobs during construction and 150 permanent positions once operational, boosting the local economy and reinforcing Belgium’s role in the European clean‑energy transition.
- Construction slated for completion in late 2027
- Full operational capacity expected by 2028
- Potential to expand to 5 GWh if demand rises
The investment underscores Tesla’s broader European strategy, which includes expanding Megapack deployments in the United Kingdom, Spain and Italy to meet rising grid‑storage demand.
“This project demonstrates Tesla’s commitment to delivering reliable, large‑scale storage solutions that enable a carbon‑free grid across Europe,” said Tesla’s European operations lead in a press release.
