Description

We have designed, manufactured and supply switchrooms for the Ørsted’s first large-scale Battery Energy Storage System (BESS) in the UK.

The project, co-located with the Hornsea 3 Offshore Wind Farm onshore infrastructure near Norwich, will be among the largest battery systems in Europe:

Power rating: 300 MW
Energy capacity: 600 MWh (≈ 2 hours nominal duration)
Shared grid connection with offshore wind for optimized efficiency

Our scope included 4 Medium Voltage Switchrooms 33kV, 2000A, 31.5kA(3s) and 1 Control Room, equipped with:

MV AIS switchgear 36kV
LV panels for protection and monitoring
Patch panels & Roxtec cabling systems
4G antenna, weather station, GPS
Swicom
Fire detection system
HVAC
Human interface panels

A project that combines technology, safety, and reliability to accelerate the energy transition.
