BW ESS has announced the launch of the UK's largest battery energy storage system (BESS), with a capacity of 100 MW/331 MWh, located near Bramley, Hampshire. According to the company, this project marks an important step forward in the country’s transition to a cleaner, more resilient energy system. 111uw

As the first European project equipped with Sungrow's advanced PowerTitan 2.0 liquid cooling technology, Bramley BESS is one of the most versatile and long-lasting energy storage assets in the UK.

The capacity of Bramley is sufficient to meet the daily electricity needs of 44,000 homes in the UK, helping to reduce emissions, costs, and energy prices, while improving system resilience. The system will play a key role in balancing fluctuating electricity demand and intermittent supply, enabling the integration of additional renewable energy into the grid.

Andreas Sohmen-Pao, Chairman of BW Group, formally inaugurated the project at a ceremony organized by BW ESS, which brought together key stakeholders from across the energy sector, including senior representatives from the project partners, Sungrow and Shell Energy Europe Limited, as well as the Right Honourable Lord James Arbuthnot of Edrom, Co-Chairman of the All-Party Parliamentary Group (APPG) on Electricity Networks.

Meanwhile, Erik Strømsø, CEO of BW ESS, stated, "This is a historic moment for BW ESS's deployment in the UK and a remarkable project within the context of the country's energy transition."

In 2024, BW ESS signed a seven-year contract with Shell Energy Europe Limited for the Bramley BESS project. This agreement represents a first in the market for a single battery energy storage asset in Europe, introducing a new revenue model for BESS projects.

Rupen Tanna, Director of Energy at Shell Energy Europe Limited, commented, "Shell Energy Europe is thrilled to collaborate on this project, which sets a benchmark for innovative revenue models in the UK and European battery storage markets."
