New York's $6 billion buried power link reached operations in 2026

The Champlain Hudson Power Express reached commercial operations in June 2026, completing a $6 billion privately financed transmission connection from Québec's hydropower system into New York City. The 1,250-megawatt project added a large new route into a dense urban electricity market through 339 miles of underground and underwater transmission.

Transmission Developers marked completion on June 16, saying the project had reached commercial operation ahead of schedule. Hydro-Québec's 25-year contract with the New York State Energy Research and Development Authority took effect June 1. The completion event and contractual start therefore represent related, but different, dates.

For electrical construction, the significant achievement was an installed and commissioned route into the city's grid. It concluded a multiyear building effort rather than announcing another comparable installation program.

The last miles mattered as much as the long cable route

CHPE's route includes 193 miles of submarine cable through Lake Champlain and the Hudson and Harlem rivers, plus 146 miles of underground cable, primarily in road and rail rights-of-way. It terminates at a converter station in Astoria, Queens.

Hitachi Energy's June announcement described a ±400-kilovolt system using voltage-source converters and announced the start of commercial operations. Its converter equipment controls the delivery of high-voltage direct-current power into the city's alternating-current system.

The connection also required local network work. New York State identified the expanded New York Power Authority Astoria Annex substation and a new, nearly four-mile underground Astoria Rainey Cable connecting to Con Edison's Rainey substation.

Those interfaces explain why a completed long-distance cable alone would not have finished the project. Converter, substation and local transmission work had to deliver power into the receiving network.

A construction financing transition accompanied the electrical transition

Transmission Developers said it refinanced $4 billion of CHPE's construction loan through a notes offering that closed June 11. The proceeds were intended to repay most of the existing credit facility and associated transaction costs.

That transaction was a refinancing of an existing asset, not another $4 billion of construction to add to the $6 billion project. It accompanied the change from building a transmission route to operating one under a long-term electricity contract.

The developer identified four principal contractors: Hitachi Energy, Kiewit, EJ Electric and NKT. Their scopes covered converter equipment, on-land construction, local system upgrades and submarine cable. These were delivery roles, not newly advertised awards.

The workforce record belongs to the completed build

The state said the project had supported more than 1,400 construction and operations jobs statewide and involved project labor agreements totaling more than three million union labor hours. Those are different measures: jobs are not hours, and neither figure is an electrician-only count.

The state also reported that a $40 million Green Economy Fund had awarded $2 million to organizations working on disadvantaged communities, workforce development and retraining. The fund's full size should not be presented as money already awarded.

The operator says commissioning finished and the line became fully operational. Operating the installed cable and converter system carries continuing monitoring, maintenance and repair responsibilities, but these disclosures do not establish that the construction workforce remains employed on the same project or quantify current vacancies.

The change was visible in the supply chain. In its August 13 first-half results, NKT said CHPE reaching commercial operation led to lower project activity, including subcontracted work, compared with the high level a year earlier. Completion had an observable effect on the work remaining to be performed.

June's completion statement also acknowledged temporary market restrictions affecting how Hydro-Québec sold electricity over the line. Physical completion, commercial operation and the pattern of actual energy deliveries are separate questions. A transfer rating of 1,250 MW describes capacity; it does not mean the line carries that amount continuously.
