Project Details
Building the Grid for Tomorrow
Fischbach & Moore has been contracted to support the construction of Dominion Energy’s Harper’s 230kV Gas Insulated Substation (GIS) in Virginia Beach, Virginia. This major utility project is part of a 21-acre switching station being developed for the Coastal Virginia Offshore Project. Once complete, the wind farm will consist of 176 turbines generating approximately 14.6 megawatts of power for distribution throughout Dominion Energy’s service area.
Fischbach & Moore’s Vital Role:
- The Harper’s GIS Substation will include 22 Mitsubishi 230 kV GIS breakers housed in an enclosed building with 16 sets of incoming and outgoing Gas Insulated Bus (GIB) feeder circuits. Installation requires 774 single-phase GIB sections of varying lengths and the assembly of more than 100 steel support structures.
- In addition to the GIS work, Fischbach & Moore received a separate contract to construct three STATCOM units within dedicated buildings at the substation site. These STATCOMs will provide critical voltage stability on high-voltage transmission circuits.
Workforce & Resources:
- Through Local 70’s support, we were able to incorporate personnel from Local 103 and Local 104 into the workforce for these projects. Collectively, the combined scope will require more than 77,000 manhours of direct and indirect labor.
Through our work at Harper’s GIS Substation, we are advancing clean energy and building a more resilient, dependable electrical grid for the future.
