Construction Progress
Open House Scheduled for May 7th
The CHPE project is hosting a pre-construction open house to explain the route and give Rockland County residents and business owners the opportunity to ask questions about the project’s construction, location and timeline on Tuesday, May 7th from 6:00 – 8:00 pm at the Patriot Hills Senior & Community Center, 19 Clubhouse Lane, Stony Point, NY, 10980. Please read the press release or download the flyer for more information. The Champlain Hudson Power Express (CHPE) officially began construction on November 30, 2022. Construction will continue throughout mid-2026, when CHPE becomes operational and begins delivering clean, renewable energy directly to New York City – aiding New York State’s green energy transition, improving air quality, and providing millions of dollars in new county and school tax revenue, all while preserving the State’s scenic landscapes and vistas. The project involves close collaboration and coordination with Hydro Quebec (HQ), which is building an approximately 58km (~36mile) underwater and underground transmission line from the Hertel substation in La Prairie, Quebec to an interconnection point with CHPE in the Rivière Richelieu, at the Canada–New York border. More information on the Hertel-New York interconnection line is available on Hydro Quebec’s website here.CHPE Construction Updates
The CHPE project uses time-tested high-voltage direct current (HVDC) energy transmission cable technology that transmits power over long distances more efficiently than alternating current (AC) transmission. CHPE HVDC cables will be installed for ~339miles underground and underwater from Lake Champlain at the U.S-Canada border to a Converter Station in Astoria, Queens, where the HVDC power will be converted to AC power so it can be injected into New York City's energy grid for local distribution.Interactive Project Map*
