H&SB Electric Transmission Line Rebuild

New York

Central Hudson Gas & Electric Corporation (Central Hudson) needed to take action to address its aging infrastructure. Electric transmission lines constructed nearly 100 years ago coming to the end of their useful life needed to be rebuilt. The lines, named “H” and “SB”, are in a 23-mile corridor between Kingston and Catskill, New York. Upgrading the existing 69 kV lines to support 115 kV will enhance service reliability and help meet the energy needs of the local communities within Ulster and Greene Counties.

VHB performed environmental reviews and identified significant natural and historical features to preserve along the route. We conducted wetland and stream delineations, engineering studies and grading plans, threatened & endangered species surveys, visual impact analyses, and supported public outreach and public hearings. We also prepared a Stormwater Pollution Prevention Plan (SWPPP) and wetlands permitting.

VHB’s coordinated efforts mean when the old transmission line is retired, the new line can slip seamlessly into service without any planned disruption to customers—or the environment.

Electric power lines traverse a remote area in upstate New York.
