BW ESS has signed a 10-year revenue-floor and optimization agreement with Denmark’s Danske Commodities for its 200 MW / 857 MWh Berkswell battery energy storage project in the UK.
The agreement covers the entire asset, which entered construction in September and is expected to become operational in the fourth quarter of 2027. Located near Solihull in the Midlands, Berkswell is co-owned with AIP Management and is expected to use Sungrow’s PowerTitan 3 technology.
The deal follows a similar agreement with BW ESS and EDF in April, covering the 350 MW / 1,243 MWh first phase of BW ESS’s Hams Hall project. BW ESS has now secured 10-year revenue floors for two of its larger UK batteries, both designed for several hours of discharge.
Neither announcement disclosed the floor level or how revenues above it would be shared, or detailed the deeper extent of the agreement.
“This agreement with Danske Commodities provides a strong commercial foundation for Berkswell and helps unlock the long-term value of this strategically important energy storage project,” said Kilian Leykam, chief commercial officer of BW ESS. “With construction under way, we are another step closer to bringing the project online and delivering critical flexibility to the UK grid.”
“We are proud to have been selected by BW ESS to optimize Berkswell,” said Jakob Sørensen, CEO of Danske Commodities. “Drawing on more than 15 years of experience in British power markets, we will use our trading expertise to maximize the value of the asset while providing the flexibility needed to integrate intermittent renewable generation. The UK is a core market for us, and Berkswell is an important addition to our growing portfolio of flexible assets.”
