Tesla has recently secured a significant win for its energy business, with a new $275 million Megapack order tied to a groundbreaking battery storage project in Scotland. Matrix Renewables has announced a full Engineering, Procurement, and Construction (EPC) agreement with Tesla to deliver a 500 MW/1 GWh standalone battery energy storage system in Eccles, marking Matrix’s first standalone BESS project in the U.K.
Situated along key transmission corridors between Scotland and England, the project is strategically located to provide critical grid flexibility, improve system resilience, and enable greater integration of renewable energy. All planning conditions have been met, with full consent secured to begin construction.
Matrix Renewables sees this project as a significant step in its European expansion and the U.K.’s clean energy transition. Sergio Arbeláez, Managing Director of Europe & Latam at Matrix Renewables, stated, “We are delivering infrastructure at the scale required to support the UK’s transition to a clean, secure, and resilient power system. This installation demonstrates our ability to execute complex, utility-scale storage projects through strong partnerships and a long-term strategic vision.”
For Tesla, this deal solidifies the Megapack as its flagship utility-grade energy storage solution. Designed for grid-scale applications, Megapack systems can store large amounts of energy and dispatch it as needed, aiding utilities in smoothing demand and integrating intermittent renewable sources like wind and solar. The technology has already been widely adopted in large-scale battery projects globally, including multiple deployments across the U.K.
Mike Snyder, Energy Vice President at Tesla, expressed excitement about supporting Matrix Renewables in their U.K. entry and collaborating on this landmark project. He emphasized the value of the partnership and the potential for future success.
This announcement comes as Tesla continues to expand its energy storage initiatives worldwide. Earlier this year, the company unveiled Megapack 3 and Megablock, its next-generation utility-scale storage products. Megapack 3 can store 5 MWh of usable AC energy per unit, while Megablock is set to debut at a newly announced $220 million BESS project in Australia.
Tesla’s order book for Megapacks has been growing rapidly, with significant deals such as a $2.7 billion order from Georgia Power in the U.S., a $375 million Megapack deal for xAI’s Colossus II data center, and various other major battery projects worldwide.
For Matrix Renewables, the Eccles project represents a significant energy storage development and a foothold in the U.K. market. The company aims to achieve up to 3 GW of additional capacity in the coming years. For Tesla, this project underscores the increasing importance of grid-scale storage as a key pillar of its business strategy.
