Sungrow and Statera team up on energy storage in UK


United Kingdom – Sungrow and Statera Energy have teamed up to supply a 362 MW/391 MWh energy storage project in the United Kingdom.

The project’s first phase was connected to the grid in Q1 2022, and the rest will be completed this year.

Sungrow’s ST3727kWh-3450UD-MV high-efficiency turnkey energy storage system solution with enhanced safety will be used by independent power producer Statera Energy to develop subsidy-free energy storage capable of discharging power at times of peak demand or under-production in multiple suburbs across the UK. More importantly, by strengthening the National Grid’s Dynamic Containment frequency response service, the project will help the UK meet its Capacity Market goal of achieving long-term supply security and contribute to offsetting the risk of increasing reliance on wind generation.

Battery assets efficiency

With lower inertia and larger, more numerous losses than ever before, the UK’s electricity system is currently experiencing lower inertia and larger, more numerous losses. Because system frequency is moving away from 50 Hz at a faster rate as a result of imbalances, faster acting frequency response products are required.

In January 2021, National Grid, the UK electricity system operator, began allowing revenue stacking in parts of the Balancing Mechanism, which has been critical to battery asset owners. The National Grid anticipates that the increased flexibility and revenue stacking will improve the efficiency of battery assets delivering the service and increase competition, lowering consumer costs.

Since its Milton Keynes branch opened in 2014, Sungrow UK, a subsidiary of Sungrow, has seen significant growth in the United Kingdom, with tens of energy storage applications. Furthermore, Europe’s largest energy storage project, the 100 MW/100 MWh Minety plant, has been operating reliably and efficiently for over a year, thanks to Sungrow’s 1500V energy storage system solutions.
