Matrix Renewables battery storage project Scotland has reached a major milestone with the close of £245 million in non-recourse financing to support the construction of a 500MW / 1,000MWh Battery Energy Storage System (BESS) in southern Scotland.
Matrix Renewables confirmed that the Eccles–Leitholm project has secured funding through an underwritten deal led by CIBC, MUFG, and NatWest, with NatWest also acting as Facility Agent.
Matrix Renewables battery storage project Scotland strengthens grid flexibility
The Eccles BESS is strategically located along key transmission corridors between Scotland and England and is designed to enhance grid flexibility, support energy security, and enable greater integration of renewable energy into the UK power system.
Battery storage is increasingly seen as critical infrastructure for balancing intermittent renewable generation, particularly as the UK accelerates its transition to low-carbon energy sources.
Nicolás Navas, CFO of Matrix Renewables, said the financing reflects growing investor confidence in storage assets and the UK energy market.
“This £245 million financing underwritten by CIBC, MUFG, and NatWest reflects the strong and growing demand for high-quality battery storage assets and reinforces the strength of our UK platform.”
Large-scale storage capacity to support decarbonisation
Once operational, the 500MW / 1,000MWh facility is expected to provide flexibility services equivalent to the annual electricity consumption of approximately 270,000 households. The project is also projected to avoid around 170,000 tonnes of CO₂-equivalent emissions each year.
Construction began in November 2025, with commercial operations scheduled for the third quarter of 2027 under a partnership with EDF.
Beyond grid support, the project is expected to generate local employment opportunities and contribute to economic activity throughout both construction and operational phases.
Investment reflects continued growth in UK energy storage
The UK battery storage sector continues to attract significant investment as developers and financiers respond to the increasing need for flexible energy infrastructure. Projects such as the Eccles BESS are central to enabling higher renewable penetration while maintaining system stability.
Matrix Renewables has worked with local authorities and environmental stakeholders to integrate the project responsibly within the surrounding landscape. A collaboration agreement has also been established with the Leitholm, Eccles and Birgham Community Council to support local initiatives.
The transaction marks a broader expansion of Matrix Renewables’ UK portfolio, which forms part of a global pipeline exceeding 15.5GW of solar, storage and green hydrogen projects.
