Sungrow agrees Constantine UK supply deal

March 14, 2023

Sungrow has agreed a deal to supply Constantine Energy Storage (CES), a grid-scale battery energy storage platform, with its liquid-cooled battery energy storage system.

Sungrow and CES are working on a pipeline of projects totalling 825MWh of capacity spread across five “ready-to-build” sites in the UK. 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/165MWh, which Sungrow says represents the “longest duration grid scale BESS [battery energy storage systems] in the UK to date. The remaining projects will be operational in 2024 and are still subject to contractual agreement.

The CES platform is funding the construction of projects, which are being 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.
