New York ISO Wholesale Market Participation

The New York Independent System Operator (NYISO) offers opportunities for Distributed Energy Resources (DER) to participate in the wholesale electricity market. Central Hudson has introduced new tariff options to better allow customers with generating and energy storage equipment to participate in NYISO markets either directly or through an aggregation.

Wholesale Value Stack – Is a new tariff option that specifies the type of compensation that customers with behind the meter generation can receive from Central Hudson when also exporting to the NYISO. Specifically, this tariff option removes energy and/or capacity compensation from the Value Stack payment made by Central Hudson for customers receiving payment for these components from the NYISO. Additionally, customers exporting to the NYISO are no longer eligible to participate in Net Energy Metering or Buyback service from Central Hudson. A comprehensive description of this tariff option can be found on the Public Service Commission’s website here.

Wholesale Distribution Service – This proposed tariff option, pending approval by the Federal Energy Regulatory Commission, establishes a wholesale distribution rate for generators, including energy storage facilities, connected to Central Hudson’s electric system for export to the NYISO market or for charging for later provision of wholesale services. Additional information can be found on the FERC’s website within Docket No. ER24-1434.

Process
For information on NYISO’s market, including requirements for applying as an aggregator or to participate within an aggregation, please visit the NYISO’s website at https://www.nyiso.com/.

Transmission Node
As part of NYISO’s wholesale market aggregation, Central Hudson’s substations are mapped to the Transmission Node(s) (PTID) that cover the Company’s territory. This Transmission Node (PTID) is established annually by the NYISO and Central Hudson’s PTID information for each substation in its service territory can be found here.

DPS Aggregation Telemetry
Aggregator telemetry provides critical data for operational situational awareness to both the NYISO and the NY Utilities. Each DER aggregator participating as part of NYISO’s wholesale market aggregation is responsible for procuring an approved RTU that connects to Central Hudson’s Energy Management System. A list of Central Hudson’s telemetry requirements can be found here.

Please reach out to wholesaleaggregations@cenhud.com to initiate the process of establishing telemetry.
