Matrix Renewables has signed a full EPC (Engineering, Procurement, and Construction) agreement with Tesla for the design, construction, and commissioning of a 500 MW / 2-hour (1 GWh) standalone battery energy storage system (BESS) located in Eccles, Scotland. The announcement was made on December 22, 2025, marking Matrix Renewables' first standalone BESS project in the UK.

Project Scale and Strategic Importance

The project represents one of Matrix Renewables' largest energy storage developments in Europe and globally to date. The 500 MW capacity with 2-hour duration translates to 1 GWh of energy storage capability. The facility is strategically positioned along key transmission corridors between Scotland and England, designed to provide critical grid flexibility, enable greater renewable integration, and strengthen system resilience.

The project directly supports the UK's Net Zero 2050 target and Clean Power 2035 ambition. All planning conditions for the project have been discharged, and full consent has been secured to commence construction.

Company Leadership Perspectives

Sergio Arbeláez, Managing Director, Europe & Latam at Matrix Renewables, emphasized the project's significance in supporting the UK's energy transition. “We are delivering infrastructure at the scale required to support the UK's transition to a clean, secure, and resilient power system,” Arbeláez stated. “This installation demonstrates our ability to execute complex, utility-scale storage projects through strong partnerships and a long-term strategic vision.”

Mike Snyder, Energy Vice President at Tesla, expressed enthusiasm about the partnership. “We are excited to support Matrix Renewables with their entry into the UK, bringing Tesla's track record in the market together with Matrix Renewables' expertise and vision. We highly value the partnership with their team and look forward to executing this landmark project together,” Snyder said.

Technical Advisory and Community Engagement

A comprehensive advisory team supports the development to ensure high technical and delivery standards throughout the project lifecycle. Enertis Applus+ is leading the technical due diligence, GHD is acting as Technical Advisor, and Black & Veatch is serving as Owner's Engineer. In line with Matrix Renewables' social commitment, a collaboration agreement has been signed with the local Community Council to deliver joint initiatives that will generate lasting benefits for the surrounding communities.

Future Expansion Plans

This project marks Matrix Renewables' entry into the UK market and signals broader expansion plans for the region. The company is actively pursuing new opportunities to expand its UK pipeline across renewable generation, energy storage, and emerging technologies. Matrix Renewables has plans to add up to 3 GW of additional capacity in the coming years, reinforcing its commitment to innovation, strategic growth, and a fully decarbonized UK power system.

Matrix Renewables is a renewable energy platform created and backed by global alternative asset manager TPG and its USD 29 billion impact-investing platform. The company's current portfolio comprises 15.5 GW of solar, storage, and green hydrogen projects in Europe, the United States, and Latin America.
