The Federal Energy Regulatory Commission accepted most of NYISO’s and New York Transmission Owners’ second compliance filing for Order 1000 while denying multiple requests for rehearing (ER13-102).

The parties have 30 days to submit a further compliance filing.

FERC denied LS Power’s request for rehearing, saying that cost-effectiveness is appropriately assessed in NYISO’s proposed evaluation process.

The commission previously expressed concern that NYISO’s regional cost allocation method for public policy transmission projects could cause unnecessary delays for transmission developers seeking regional cost allocation. FERC accepted the ISO’s proposal that the process for deciding the cost allocation method run in parallel with state siting proceedings.

FERC also:

  • Accepted NYISO’s revisions clarifying how it will review transmission owners’ local transmission plans to determine whether alternative transmission solutions might meet reliability needs. FERC noted that NYISO and the Long Island Power Authority have agreed to tariff revisions that allow LIPA to determine whether “a proposed transmission need driven by public policy requirements requires a physical modification to transmission facilities located solely within the Long Island Transmission District, while also allowing the New York [Public Service] Commission to determine that a transmission need driven by public policy requirements identified by LIPA is a regional transmission need driven by public policy requirements.”
  • Accepted NYISO revisions on who may qualify as an approved transmission developer. A prospective transmission developer will be allowed to submit a detailed plan for financing, developing, constructing, operating and maintaining a transmission facility. The ISO may require information about transmission facilities that the prospective developer has already constructed.
  • Ordered NYISO to treat whether or not a nonincumbent developer has received its siting permits and other authorizations under New York state law as just one factor in the ISO’s selection process.
  • Ordered revisions to clarify that only disputes within the New York PSC’s sole jurisdiction may be subject to judicial review in state courts.
