In one of the largest green debt transactions for battery storage infrastructure in the UK, Pulse Clean Energy has announced the successful closure of a £220 million financing deal. Backed by a consortium of six global financial institutions—Santander, NatWest, ABN AMRO, NORD/LB, Investec, and CIBC—the deal marks a significant step forward in advancing the UK’s energy transition through large-scale battery storage deployment.
Structured in line with the Green Loan Principles of the Loan Market Association, the deal was coordinated by Santander Corporate & Investment Banking. The funds will be used to construct six ready-to-build battery energy storage system (BESS) projects, collectively offering over 700MWh of capacity. Notably, four of these sites are repurposed former diesel generator facilities—demonstrating Pulse’s commitment to transforming legacy fossil fuel infrastructure into clean energy assets.
In addition to these new builds, the financing will support ongoing operations and construction across nine other BESS sites currently active or in late-stage development. The projects are strategically located throughout the UK, including key regions such as Scotland, Devon, Greater Manchester, and Wales.
The energy storage assets are expected to deliver more than £200 million in gas and emissions savings over their lifetime. By enabling flexible, time-shifted delivery of renewable energy, the batteries will play a pivotal role in reducing reliance on gas peaker plants and improving grid stability—while helping consumers benefit from cheaper, cleaner electricity.
With this funding, Pulse Clean Energy strengthens its position as a leading battery storage developer in the UK, aiming to reach over 2GWh of operational capacity by 2030. All systems financed under this deal are slated to be operational by 2027.
The financing also reflects growing investor confidence, enabling the National Wealth Fund (which previously backed Pulse) to step aside as commercial lenders take the lead in a maturing storage market.
