EDS HV has completed its electricals design and commissioning support scope for Vattenfall’s 22MW battery storage project at Pen y Cymoedd in south Wales.
The contractor was responsible for the electrical design review and grid consultancy of the battery@pyc site co-located with Vattenfall’s 228MW Pen y Cymoedd wind farm.
The James Fisher subsidiary produced the design and specification for the protection and operation of the 33kV switchboard plus cable rating calculations.
EDS also provided HV authorised staff, commissioning support and oversaw testing for the project featuring BMW lithium-ion batteries energised in late April.
“The complexities of the project meant that we had to provide some very clever engineering solutions,” said EDS principal engineer Luke Bishop.
