China-headquartered Sungrow has agreed to supply 1.4 GWh of its latest generation battery energy storage systems to developers Penso Power and BW ESS for their massive project in the UK.

The supply deal is for 280 sets of PowerTitan 2.0 liquid-cooled energy storage systems, which will be installed at the 350 MW/1750 MWh Hams Hall energy storage project, currently under development in North Warwickshire, England. The five-hour storage system secured the planning approval back in 2022.

With the UK market undergoing challenges in terms of reduced grid inertia and voltage instability due to the significant integration of renewables, the demand for grid-scale energy storage technology within the UK’s ancillary service market has skyrocketed.

Therefore, the systems provided by Sungrow will be designed specifically for grid-forming. The systems will be capable of millisecond-level response, helping to address instabilities in grid frequency and voltage. In addition, they will boast a black start capability, enabling swift intervention when regional power sources disconnect from the grid, promptly restoring power supply.

In July, Sungrow inked three landmark energy storage contracts with Saudi Arabia’s Algihaz Holding, amounting to 7.8 GWh. At the time, this was the world’s largest grid-side storage order, but was eclipsed by Tesla’s 15.3 GWh Megapack supply contract in the US only a couple of days after.

For BW ESS and Penso Power, the supply deal with Sungrow is the second major announcement for the UK market in recent weeks. Last month, the two developers announced a long-duration tolling agreement with Shell Energy Europe for a 100 MW/330 MWh battery energy storage system, scheduled for commissioning in late 2024. The fixed-price deal came at a time of reduced revenues for batteries trading in Great Britain’s electricity wholesale markets.
