Champlain Hudson Power Express

The Champlain Hudson Power Express (CHPE) project will propel New York City into a sustainable future with clean, renewable hydropower. Spanning 339 miles, CHPE will supply 1,250 MW of hydropower from Canada to Queens through a buried high voltage direct current (HVDC) transmission line.

CHA is providing engineering design, environmental support, permitting, and inspection services for approximately 84.5 miles of upland cable installation. CHA’s design services include approximately 90 horizontal directional drilling crossings for HVDC electrical transmission cables and a telecommunications line in the Hudson River Valley, optimizing route choices to avoid environmental disruptions. The buried transmission line reduces its environmental footprint and enhances resilience against severe weather conditions while bolstering overall safety measures.
