Island Green Power Secures £315 Million Growth Financing Facility
London, UK – 06. July 2026, Island Green Power (“IGP”), a leading UK-based clean energy developer and power producer, specialising in solar PV and battery energy storage systems (“BESS”), has successfully closed a £315 million HoldCo debt financing, provided by Nomura and Barclays, that will support its strategic transition from a pure development business into an independent power producer.
The HoldCo facility is being used to refinance existing debt and provide flexible capital to support the growth of the business and facilitate the construction of IGP’s first projects, including the West Burton solar project, the largest solar project to ever have been awarded a Contract for Difference (“CfD”).
100% owned by funds managed by Macquarie Asset Management, the company has a long and proven track record, having successfully brought more than forty projects to Ready-to-Build (“RtB”) stage, representing approximately 4 GW of capacity.
IGP is focused on delivering and operating large-scale solar and BESS projects classified as Nationally Significant Infrastructure Projects (“NSIPs”). The Company has received planning consent for two of the largest co-located solar and BESS projects in the United Kingdom: Cottam Solar Farm, with a 600 MWAC connection agreement, and West Burton Solar Farm, with a 480 MWAC connection agreement. IGP has more than 17 GW of utility-scale solar and BESS projects in its pipeline, including five NSIPs currently in the planning examination process.
