Northeastern RTOs see no need for interregional transmission projects for now

Citinga previously approved project that went into service in late 2015, the threeRTOs/ISOs that operate in the Northeast and Mid-Atlantic have determined thatno new interregional transmission projects are needed at this time.

ThePJM Interconnection LLC,New York ISO andISO New England Inc.on April 11 published their "2015 Northeastern Coordinated System Plan."In the plan, they said they did not identify any new interregional transmissionprojects that "would be more effective or cost efficient in meeting theneeds of multiple regions" than proposed improvements within theindividual markets as of Dec. 1, 2015.

Accordingto the report, no new interconnection projects were approved in 2014 or 2015but a previously approved 345/115-kV interconnection between PJM and NYISO wasactivated in November 2015. The project connects the central Pennsylvaniaborder with New York on the Homer City-Watercure 345-kV line at a substation inMainesburg, Pa. A second baseline reliability project in the same area wasapproved in 2012. Expected to go into service in June, the project willestablish a new tie point on the Homer City-Stolle Road 345-kV line at asubstation in Farmers Valley, Pa.

Thereport also focused on the regions' joint compliance with FERC's Order No. 1000to address interregional transmission planning and cost allocation. Inaddition, the report summarizes interactions and participations with otherplanning entities, such as the North American Energy Reliability Corp., and itsregional reliability entities, the Northeast Power Coordinating Council andReliabilityFirst Corp.
