FERC on Monday granted NYISO eight extra months — until year-end — to fix a “misalignment” between its market software and its Tariff rules (ER20-1470).

Section 4.4.1.2.1 of the ISO’s Services Tariff allows generators that are committed day-ahead only for non-synchronous operating reserves to modify their minimum generation bids in real-time, but the ISO recently discovered that its software does not provide the flexibility intended by that provision.

NYISO explained that its software currently is preventing all generators, even those that only receive a day-ahead schedule for non-synchronous operating reserves, from modifying their minimum generation bids in real-time.

The ISO said it expects to deploy the necessary software improvements coincident with its broader software revisions to implement fast-start pricing reforms that the commission already accepted in a February order (ER20-659).

Granting the waiver “will allow NYISO to develop and implement software consistent with its business practices without the need to rush a software patch,” the commission said.

However, the waiver will be in effect for only the period necessary for NYISO to code software modifications, perform the necessary quality assurance testing and deploy the software consistent with its standard software development practices, the commission said.

NYISO also asked the commission to “excuse any instances of past non-compliance with the provision at issue,” adding that any such instances “cannot be corrected or reversed.”

“Upon consideration, we will exercise our discretion in addressing such matters and, given the facts and the record before us in this matter, we take no action with respect to the instances of NYISO’s past non-compliance,” the commission said.
