The NYISO – PJM Joint Operating Agreement covers the PJM – NYISO Interconnection Facilities under the Operational Control of the NYISO and PJM.
NYISO and PJM shall jointly develop and maintain a ‘PJM – NYISO Interconnection Facilities List’ (including a description of the facilities and metering points) and post the most current mutually agreed upon list on their respective public websites. The Parties may jointly revise the list by mutual written agreement. After the Parties mutually agree to changes, NYISO and PJM shall post an updated list on their respective websites. Neither Party shall knowingly post a list that includes changes that are not the product of mutual agreement.
The PJM-NYISO Interconnection contains twenty-five (25) alternating current (“AC”) Interconnection Facilities, seven (7) of which form one (1) AC pseudo-tie[1]; and further contains two (2) HVDC Interconnection Facilities as well as one (1) Variable Frequency Transformer (VFT).
For Operational Control purposes, the point of demarcation for each of the Interconnection Facilities is the point at which the Interconnection Facility crosses the PJM-New York State boundary, except as otherwise noted in the PJM – NYISO Interconnection Facilities List posting.
