New York Regional Interconnection (NYRI)

The New York Regional Interconnection (NYRI) is a plan to build a 190-mile $2.1 billion 1,200-megawatt transmission line from the Utica area through seven upstate New York counties to Orange County to the New York City area. NYRI is a U.S. corporation owned by a series of Canadian holding companies . The high-voltage, direct current (HVDC) power line is needed to improve the state's aging power grid and reduce the threat of blackouts like the one that struck the state in 2003. The state Public Service Commission is holding a serious of 13 public hearings on the project. AAEA supports the project. If approved, the project is expected to be completed in 2018. [Note: we still do not understand why direct current will be used because AC is a more efficient way to move electricity].

The cables are made of steel with aluminum cladding and will be uninsulated. The pipeline route will have 83’- 120’ high scaffold-like towers and the river route 130’-180’ high monopoles. Each main cable would carry 400,000V and 1.2 billion watts. There will be at least 2 cables on each pole or tower, plus a return. On the monopoles, there would be room for 2 more cables.
