January 13, 2026
Renewables developer Elements Green has completed the acquisition of the 148.8MW battery energy storage system (BESS) project in West Sussex from developer Envirotech Energy Solutions.
Located near Wineham, the company has secured full ownership of the Bolney Green Energy Hub after signing a share purchase agreement (SPA). The BESS project has a 4-hour duration and is scheduled to be fully operational in the fourth quarter of 2027.
Planning approval for the project was secured back in September 2024 from Mid-Sussex District Council.
The acquisition of the Bolney Green Energy Hub follows the recent financial close of another BESS project in Nottinghamshire, the 360MW/720MWh Staythorpe. Construction of the £71.5 million BESS project began in August 2025 and is expected to be fully commissioned in mid-2027.
“This 4-hour duration project is exactly the type of high-integrity infrastructure needed to support a flexible and reliable renewable energy future. With the SPA now signed, our team is focused on delivering this 148.8 MW asset as part of our wider 13,000 MW global pipeline," said Rasmus Friis, CEO of Elements Green.
The newly acquired BESS project will join a development portfolio of more than 13GW of utility-scale solar PV and BESS projects across the UK, the EU and other markets.

In related renewable energy project acquisitions, investment manager Downing has completed the acquisition of two solar PV plants from developer BOOM Power.
Both consented solar PV projects are located near Wakefield in West Yorkshire and are the 22.2MW New Hall Solar Farm and the 49.9MW Low Farm Solar Farm. According to Downing, the New Hall Solar Farm has been designed with a strong focus on environmental stewardship, incorporating biodiversity enhancements.
These acquisitions align with Downing’s long-term investment strategy, which focuses on building and managing renewable energy assets that deliver stable returns.
Mark Hogan, founder of BOOM Power, said: “The transactions represent another important milestone for BOOM Power and underline the strength and flexibility of our development platform. We are proud to have progressed these projects through consent and to see them move forward with Downing, whose long-term investment approach aligns well with our vision for delivering high-quality renewable energy infrastructure.”
