21MVA Battery Energy Storage System

The client required the design, construction, and commissioning of a 21MVA Battery Energy Storage System (BESS) compound in Broadditch, Kent.

THE CHALLENGES

Site earthing presented a challenge due to the 33kV overhead line connection and the planned future 11kV connection, requiring careful consideration of combined fault contributions and differing clearance times. In addition, site constraints made plant installation difficult, as the six 32-ton batteries required a complex lifting operation into position.

WHAT WE DELIVERED

  • 6nr batteries
  • 3nr transformers
  • 460m of 33kV cabling,
  • 2-panel 33kV switchboard,

“From the outset, the project relied on careful design integration and coordination on site to manage constraints and ensure safe installation. That approach was key to achieving a robust and compliant end result.“
