The Bramley 331MWh BESS, developed by BW ESS and deploying Sungrow Battery Energy Storage Systems (BESS), has officially entered commercial operation. Sungrow achieved grid energization to commercial operation in a period of just two weeks, a 72% efficiency gain, setting a new record for BESS delivery in the UK and across Europe.
Erik Strømsø, CEO of BW ESS, commented in a commendation letter: “In just two weeks, you accomplished the HOT commissioning, compliance testing and ancillary service testing – an impressive feat. We thank you for your efforts and look forward to future collaborations.”
In the UK, the time from grid energization to commercial operation for an energy storage project typically takes several months due to factors including commissioning, compliance testing and final regulatory approvals, with significant delays potentially arising from grid connection backlogs.
The all-in-one AC-DC block design of Sungrow’s PowerTitan 2.0 system, with pre-assembled battery modules and PCS, ensured seamless integration, significantly reducing site installation time.
Conventional systems require separate PCS and battery cabinets for on-site wiring and commissioning. In contrast, the AC-DC block design completes pre-installation and pre-commissioning at the factory, simulates diverse grid scenarios to validate PCS performance, and conducts grid adaptability tests under extreme conditions at the factory, significantly reducing commissioning timelines.
For the Bramley project, Sungrow not only shortened the grid energization to commercial operation cycle from the industry minimum of 50 working days, but also responded promptly to the testing needs of the project operator and the grid. The Sungrow team completed and passed all grid ancillary services tests in just one and a half days, significantly reducing testing time and enabling earlier energy trading and grid service benefits for customers.
Backed by over 520 service centers worldwide, Sungrow delivers 24/7 technical support across more than 180 countries, ensuring rapid response to client needs. The company is reconstructing industry standards with systematic service capabilities, providing customers with an end-to-end experience that exceeds expectations from planning and design to operation and maintenance optimization, helping to accelerate the global energy transformation process.
