New York PSC approves Propel NY Energy transmission settlement
Built World90-mile underground line would link Long Island to the state grid by 2030
Overview
New York regulators approved the Propel NY Energy settlement on September 17, a major step for a 90-mile underground transmission line. The Public Service Commission (PSC) said the line is needed as old power plants retire, despite arguments that canceled offshore wind projects removed the need.
The $3.26 billion project, a joint effort by New York Transco and the New York Power Authority, still needs several approvals. The PSC must sign off on environmental management and construction plans, and the Army Corps of Engineers must approve the underwater segment. North Shore communities have filed a motion to dismiss; developers say some construction could begin later this year, with full construction in mid-2027 and completion by 2030.
Why it matters
If this line isn't built by 2030, New York City and Long Island face growing blackout risk as old plants retire and demand climbs.

Scenarios
PSC approves first EM&CP phases, construction starts
Discussed by: PSC staff, New York Transco, NYPA
After the October 1 comment deadline, the PSC could approve the first two EM&CP phases and deny the motion to dismiss. Developers say some construction could begin later this year, with full construction in mid-2027.
Motion to dismiss delays EM&CP approval
Discussed by: Village of Sea Cliff, Protect Our Coast LINY, school districts
The PSC could defer EM&CP approval while it considers the motion to dismiss and the Khazanovich Declaration. That would push construction into 2027 and could threaten the May 2030 in-service date.
