In early February 2025, the Bramley 331MWh Battery Energy Storage System (BESS), developed by BW ESS and equipped with Sungrow's energy storage technology, achieved commercial operation. Notably, Sungrow completed the entire process from grid energization to operational launch within two weeks—a 72% efficiency improvement compared to industry benchmarks—establishing a new milestone for BESS deployment timelines in the UK and Europe.
Erik Strømsø, CEO of BW ESS, acknowledged this achievement in an official commendation, stating that Sungrow had executed critical phases including HOT commissioning, compliance testing, and ancillary service validation within an unprecedented timeframe. He emphasized appreciation for the collaborative effort and expressed anticipation for future partnerships.
The accomplishment stands in contrast to typical UK energy storage project timelines, where grid connection backlogs, multi-stage approvals, and testing protocols often extend processes to several months. Analysis reveals two key drivers behind this record-setting execution: the innovative architecture of Sungrow’s PowerTitan 2.0 platform and the deployment of a cross-functional technical team.
Sungrow’s PowerTitan 2.0 system features an integrated AC-DC block configuration with factory-preassembled battery modules and power conversion systems (PCS). This design eliminates on-site wiring complexities by completing grid adaptability simulations and performance validations under extreme conditions during manufacturing. Unlike conventional setups requiring separate PCS-battery cabinet installations and extended field commissioning, the prefabricated solution reduced on-site integration efforts by approximately 70%.
To meet BW ESS’s stringent timeline for the Bramley project, Sungrow mobilized a specialized task force comprising R&D engineers, project delivery managers, and on-site technicians. This team streamlined workflows across planning, testing, and compliance phases. Notably, grid ancillary service tests—typically spanning weeks—were completed in 1.5 days through preemptive scenario simulations and real-time technical adjustments. The accelerated timeline enabled BW ESS to commence energy trading and grid service monetization 48 days ahead of industry norms.
Sungrow’s global service infrastructure, supported by 520+ technical centers and 24/7 responsiveness across 180 countries, further ensured operational continuity. Leveraging 28 years of sector-specific expertise, the company continues to redefine industry benchmarks through end-to-end solutions spanning design optimization, predictive maintenance, and lifecycle performance enhancements, positioning itself as a catalyst for global energy transition initiatives.
