FERC on Thursday approved NYISO’s request for up to three more years to implement tariff revisions that will allow distributed energy resources in aggregations to provide all ancillary services they are capable of, in compliance with Order 2222 (ER21-2460).

NYISO last month proposed to extend the revisions’ effective date from the fourth quarter this year to a “flexible” date of no later than Dec. 31, 2026, because of unexpected delays in developing and implementing the necessary software modifications.

The ISO said it will not necessarily need all of that time to complete the necessary work. It noted that it is still on track to implement the DER aggregation and participation models accepted by the commission in 2020 by the third quarter of 2023 and, as a result, may be able to start having aggregations participating in its markets far in advance of 2026.

It also said that in 2024 it will start deploying software that will automate much of the work that will at first be done manually by staff.

NYISO had earlier this year requested for more time to submit its Order 2222 compliance filing; as part of compliance with the order, each RTO and ISO was required to propose a date by which it could complete the necessary work integrating DERs into their markets. (See NYISO Requests Extension, Clarification on Order 2222 Compliance.)

In its brief order, FERC noted that no answers were filed in response to NYISO’s request, approving it without further comment.
