NORWICH – The New York State Public Service Commission called the circumstances surrounding the New York Regional Interconnect Inc. power line case “extraordinary” and “unusual,” in a ruling issued by the agency Monday.

However, the state’s transmission siting authority also referred to recent arguments provided by several of the NYRI opposition groups as “repetitive,” warning that a pattern of recycled evidence in the future could cause the review process to become expensive and inefficient.

NYRI is an Albany-based developer proposing to construct a 190 mile-long, 1,200 megawatt power line from Oneida to Orange County, in what company officials say is an effort to alleviate downstate electricity constraints. The line would traverse 44 miles of Chenango County.

“Our initial review of the opposition responses to the NYRI waiver motion shows substantial overlap and repetition of the same substantive points,” the ruling states. “We urge the parties to take note that the strength or the merit of an argument is not often fortified by its mere repetition.”
