This is a 230/69/13-kV, Class H gas-insulated switchgear (GIS) substation. Working with PSE&G and its GIS vendors, Burns & McDonnell provided site development, designed, procurement and installation of Bergenfield Substation facilities, including the GIS building. The 230-kV and 69-kV GIS equipment was installed by the GIS vendors. The work included installation of two three-phase 230/13-kV transformers and a three-phase 230/69-kV autotransformer; a masonry GIS building with the control room as a second floor above the 69-kV GIS equipment; a 12-cubical 13-kV switchgear, two 230-kV high-pressure fluid filled (HPFF) underground riser structures, three 69-kV XLPE riser structures including station light and power transformers; oil containment for the transformers; and protection and controls for the new substation and associated 230-kV and 69-kV lines.
This is one of multiple engineer-procure-construct (EPC) projects Burns & McDonnell completed for PSE&G. To facilitate aggressive project schedules, the utility selected the EPC approach to allow parallel scoping, preliminary design, detailed engineering, procurement and construction activities, cutting months from the typical project cycle. This has resulted in on-time energization schedules under critical outage windows. Burns & McDonnell works closely with PSE&G to prequalify and select subcontractors and suppliers, including vendors familiar to either or both firms.
