CRIS Revisions Approved
NYISO’s Management Committee on Wednesday approved the ISO’s proposed tariff revisions related to the expiration and transfer of capacity resource interconnection service (CRIS).
The multiyear effort intends to enhance CRIS rules, with the objective of spending 2023 finishing the functional software requirements necessary to allow the ISO to track partial CRIS expirations.
The proposals seek to facilitate increased capacity deliverability by lowering the cost of new entry into the capacity market for an internal generator or an unforced capacity deliverability rights (UDR) facility looking to either transfer their CRIS rights to a same-location unit or expire their partial CRIS rights.
NYISO also adjusted the CRIS retention rules by enabling deactivated facilities to simply notify the ISO at any point that they will voluntarily relinquish their CRIS.
The Long Island Power Authority continued to object to the changes, saying they “do not address their concerns with CRIS expirations associated with interregional transmission ties with UDR,” while three other organizations abstained from the vote. (See ‘CRIS Revisions Advance,’ NYISO Business Issues Committee Briefs: Jan. 18, 2023.)
The proposals now move to the Board of Directors for approval. NYISO anticipates filing the rules with FERC before the end of the first quarter.
External and Virtual Transaction Errors
Sheri Prevratil, NYISO counterparty and credit risk manager, told stakeholders that the ISO identified typographical errors in the tariff language related to changes to credit requirements for external and virtual transactions, approved last year. (See ‘Credit Requirements on Virtual Transactions,’ NYISO Management Committee Briefs: Nov. 30, 2022.)
Prevratil said the two errors “changed one digit in the import supply table and one digit in the virtual supply table,” though these “did not affect the analysis presented to the MC, and [the ISO has] already updated the presentation and tariff language” accordingly.
In response to a question from Howard Fromer, who represents Bayonne Energy Center, Prevratil confirmed that the tariff changes have not yet been filed with FERC and said NYISO intends to first seek board approval for them in February.
