Independent power producer Cero Generation has purchased a 100MW battery energy storage system project located in Gloucestershire, England, from Longspur Capital and RE Projects Development Limited (REPD). This marks another addition to the UK solar and storage company's expanding portfolio.
The acquisition represents the most recent development for Cero, which operates under Macquarie's Green Investment Group (GIG), a division of the global infrastructure investment firm. Moving forward, Cero will collaborate with its UK development partner Enso Energy to advance the project through construction phases and into operational status, though no specific commercial operation date has been disclosed. The deal was announced on October 27 through LinkedIn.
Declan Deasy, CEO of Cero Generation, commented: "This acquisition demonstrates our continued investment in the UK's renewable infrastructure, delivering further benefits for the UK's energy system, communities and environment."
Macquarie established Cero Generation in 2021 as a solar and storage owner-operator, initially focusing on the UK market while maintaining broader European expansion goals. The parent company operates two additional UK entities in the clean energy sector: Island Green Power, a developer purchased entirely in May 2025, and Eku Energy, a global BESS owner-operator whose UK assets include two battery systems totaling 130MWh that began operations in August.
Earlier this year in July, Cero Generation obtained £200 million in financing from a lending group comprising ING, NordLB, Rabobank and Santander UK to develop its 360MW UK solar and storage project pipeline.
The firm gained significant attention previously for delivering Larks Green, the UK's inaugural transmission-connected solar-plus-storage facility, which combines 70MWp of solar capacity with a 49.5MW/99MWh battery energy storage system.
