Sungrow to Supply Solution for UK’s Longest Duration BESS Project of 825 MWh

Chinese inverter manufacturer Sungrow Power Supply Co. has announced a deal to supply Constantine Energy Storage (CES) with its liquid-cooled BESS solution called ‘Power Titan’. CES is a grid-scale battery energy storage platform.

Sungrow and CES are working on a specific pipeline of projects totalling 825 MWh of capacity spread across five ready-to-build sites. Construction has already started at Ocker Hill, near Birmingham, and Capenhurst, near Chester, both of which will be energised later this year and are each 57MW/165 MWh representing the longest duration grid scale BESS in the United Kingdom to date.

Sungrow said that the remaining projects will be operational in 2024 and are still subject to contractual agreement.

The CES platform is funding the construction of a pipeline of BESS projects developed by Pelagic Energy Developments, a subsidiary of Constantine Group. CES will acquire these sites once operational and operate them long-term. The CES platform is majority-owned by institutional investors Alberta Investment Management Corporation (AIMCo) and Railpen, along with Constantine Group.

Sungrow Senior Vice President James Wu said on the deal, “Constantine Energy Storage is at the very forefront of enabling the energy transition on these shores, and we at Sungrow are happy to assist them in creating a better, cleaner future for everybody. We hope this agreement will be a forerunner for other important deals in the future.”

Louis Burford, Operations Director, CES stated, “Energy storage is essential if we want to decarbonise our country’s energy system. That’s why Constantine Energy Storage is working hard to build out a portfolio of battery energy storage systems across the country. This ground-breaking deal with Sungrow is significant and represents an important milestone in our mission to support the UK’s transition to net zero.”

Sungrow has supplied over 340 GW inverter installed worldwide as of December 2022.

Constantine Energy Storage (CES) is a Surrey-headquartered platform to construct, own and operate institutional grade BESS. Alberta Investment Management Corporation (AIMCo) and investment manager Railpen jointly own a 94% stake in CES which has plans to build out a pipeline of projects in the UK. These projects are currently under development by Constantine Group subsidiary Pelagic Energy Developments.
