PROJECT DESCRIPTION

Kirby was responsible for the design and build of the electrical system associated with the 75MW Poolbeg Battery Energy Storage System (BESS) Plant connecting to the Eirgrid 220kV system via the Poolbeg 220kV substation. The scope of works included electrical and civil works associated with the electrical balance of plant, including design, procurement, installation and erection, testing and commissioning of works and civil and electrical works for all the BESS equipment. A 220kV underground gridline circuit was successfully installed through the main roads within the existing power plant, navigating the many services encountered to successfully achieve a highquality installation in a highly congested operational brownfield site.
