Gresham House Energy Storage Fund secured GBP 141 million of senior debt for three UK BESS projects totaling 397 MW/794 MWh. The portfolio includes the 240 MW/480 MWh Cockenzie project in Scotland, 57 MW/114 MWh Monet’s Garden in North Yorkshire, and 100 MW/200 MWh Elland 2 in West Yorkshire. All three two-hour systems are expected online in 2027.

The deal signals a clear shift in UK BESS financing. Capital is moving from equity-led development exposure toward structured, long-tenor project debt for construction-stage assets with grid visibility and near-term revenue potential.

The debt package covers up to 70% of individual project costs and carries a repayment profile of at least 15 years. Gresham House, a listed battery storage investor, will fund the balance through equity contributions and export credit financing agreements already secured for Cockenzie and Monet’s Garden.

This mirrors wider European storage deal behavior. Enerdatics data shows Europe recorded a 120% year-on-year surge in BESS transactions in Q3 2025, with the UK, Germany, and Italy accounting for over 60% of traded capacity as investors targeted advanced-stage storage projects.

For lenders, the commercial logic is execution visibility. Grid-connected, two-hour UK batteries can access merchant revenues, balancing markets, and optimization upside without taking early-stage development risk.
