BW ESS and Danske Commodities sign 10-year optimisation agreement for 200 MW / 857 MWh battery in the UK
Under the terms of the 10-year floor agreement, Danske Commodities will provide trading and optimisation services for the entire asset. The agreement marks a significant milestone in the commercialisation of Berkswell, which entered construction in September 2026 and is expected to become operational in Q4 2027. Developed by BW ESS from greenfield origination and co-owned with energy and decarbonisation investor AIP Management, the project forms a key part of BW ESS’ UK portfolio.
Once operational, Berkswell will be capable of supporting the electricity needs of around 700,000 UK homes for up to four hours. By storing electricity when generation is abundant and discharging it when demand increases, the project will support the integration of renewable energy and strengthen the resilience, flexibility and security of the UK electricity system.
Located near Solihull in the Midlands, Berkswell is strategically positioned near major centres of electricity demand, enabling it to provide flexibility where it is needed most and help maintain a reliable power supply. The four-hour battery system will be among the longest-duration battery storage sites in the UK. The project is expected to use Sungrow’s PowerTitan 3 technology to deliver the efficiency, reliability and performance required by the evolving UK electricity network.
“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 optimise 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 maximise 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.”
