Enderby Battery Storage

Hopkins Energy successfully completed the Enderby Battery Storage Project, installing 16 new CATL BESS units and reconfiguring existing Sungrow units to ensure compatibility with the Sungrow Power Conversion System (PCS).

The project involved retaining Sungrow BESS units in their original positions while disconnecting and replacing outdated DC and communication cabling. Trenching, ducting, and new cabling were installed to connect these units to updated PCS locations. For the new CATL BESS units, the team prepared the ground, installed 16 concrete plinths, laid trackways, and implemented a new earthing system. Auxiliary power and communication cabling were also installed and tested.

Hopkins Energy reviewed and updated the electrical design to ensure compatibility, installing three new LV feeder pillars and updating auxiliary power connections. Comprehensive testing was completed to verify functionality. Throughout the works, 24/7 site security was in place to safeguard equipment and maintain safety.

This project was completed efficiently, ensuring seamless integration of new and existing systems.

Penwortham Battery Storage

Hopkins Energy successfully completed the Penwortham Battery Storage project, involving the installation of new CATL Battery Energy Storage System (BESS) units and relocation of existing Sungrow BESS units. Gresham House oversaw equipment delivery and commissioning.

Key activities included reconfiguring cabling, removing PCS units 1–8, and updating connections from battery containers 2–8 to PCS units 9–15. The CATL BESS installation involved preparing ground, installing concrete plinths, positioning BESS and auxiliary cabinets, stabilising with shingle, and constructing trackways. Cable management covered laying and terminating DC, auxiliary, and communications cabling, along with installing a new earthing system. HV services were reconfigured, and new cabling was installed for PCS and auxiliary connections. Hopkins Energy conducted testing on all new cabling, while Gresham House commissioned BESS systems and communications. Site security measures were implemented to safeguard equipment and ensure safety throughout the project.

This collective effort ensured the project’s smooth and successful completion.
