Bramley 331 MWh BESS Project: A New Record for BESS Delivery in the UK and Across Europe
Project Type:
BESS
Capacity:
100 MW/331 MWh
COD Time:
2025
Record-Breaking Delivery Speed
The 100 MW/331 MWh Bramley Energy Storage Project is now commercially operational, supporting grid flexibility across the UK. Powered by Sungrow’s PowerTitan 2.0 system, the project achieved commercial operation just two weeks after grid connection—about 72% faster than the industry average. This sets a new benchmark for speed and efficiency in large-scale energy storage. Let’s take a look at what made it possible.
Tight Deadlines Required Seamless Collaboration
To meet the tight delivery schedule of the Bramley project, Sungrow dedicated a project team, uniting the technical experts from HQ with on-site engineers. From start to finish, the team ran a closed-loop management system, staying on top of every detail: anticipating risks, tracking real-time progress, coordinating schedules, and even pre-positioning spare parts. When unexpected grid anomalies caused outages, the team leaped into action—diagnosing the issue and safely shutting down the system in just 2.5 hours, all while optimizing the system in parallel. Using Sungrow’s Power Plant Controller (PPC), they passed all ancillary service tests in just 1.5 days. Thanks to this tight collaboration and rapid troubleshooting, Bramley reached commercial operation just two weeks after grid connection—72% faster than the industry average.
Proactive Testing Accelerated Commissioning
With limited on-site time and no access to real-time grid charging, the team turned to simulation. By using diesel generators to simulate extreme grid conditions, they were able to configure technical settings in advance and identify key risks such as PCS communication issues and battery over-discharge. This early testing enabled swift fixes, real-time adaptation to UK grid specifications, and a smooth, accelerated commissioning process.
An All-in-One System, Built for Fast Deployment
The Bramley project chose Sungrow's PowerTitan 2.0 solution, which brings together electrochemistry, power electronics, and grid tech in a single, integrated system. Its smart battery management system keeps everything stable—from individual cells to the full system, while its factory pre-testing means it’s operationally ready upon delivery. The result? Fast, simplified installation and near-instant grid connection, raising the bar for delivery speed in energy storage.
When Everything Just Works
Erik Strømsø, CEO of BW ESS, praised the achievement in a letter of commendation: “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.” This two-week milestone wasn’t luck—it was the result of disciplined execution, forward-thinking risk planning, and seamless global teamwork. By blending innovation with precision, Sungrow is setting a new pace for fast, dependable energy storage delivery.
