BW ESS has launched its 100MW / 331MWh battery energy storage system (BESS) in Bramley, Hampshire, marking the largest project of its kind to begin operations in the UK. The project is seen as a crucial step in advancing the UK's transition to a more resilient and sustainable energy grid.
At a ceremony hosted by BW ESS, Andreas Sohmen-Pao, Chairman of BW Group, officially inaugurated the project. The event brought together key stakeholders, including senior representatives from project partners Sungrow and Shell Energy Europe Limited.
Bramley BESS is the first European project to feature Sungrow's advanced PowerTitan 2.0 liquid-cooled technology and is among the UK's longest-duration energy storage assets. The system will help balance the fluctuating electricity demand and supply, enabling greater integration of renewable energy sources into the grid.
Erik Strømsø, CEO of BW ESS, said: “This is a landmark moment for BW ESS' UK roll-out, and a notable project in the context of the UK's energy transition. Bramley is a state-of-the-art, pioneering project aligned with our mission to unlock the value of energy storage.”
He added, “I'm grateful that so many of our peers and partners were able to join us to mark the occasion.”
The 100MW BESS has the capacity to meet the average daily electricity needs of 44,000 homes in the UK. It is expected to contribute to reducing emissions, energy costs, and price volatility, while enhancing grid resilience.
Richard Thwaites, Executive Director and Head of UK for BW ESS, also commented, “We are proud to see the Bramley BESS reach commercial operation. This reflects the dedication and expertise of the project team, as well as strong collaboration with local communities and authorities, whose engagement has been invaluable throughout the project's development.”
In 2024, BW ESS entered into a seven-year tolling agreement with Shell Energy Europe Limited for the Bramley BESS, further strengthening the role of energy storage in supporting the UK's clean energy ambitions.
