FERC on Tuesday approved NYISO’s request for a 30-day extension for submitting additional reliability-must-run tariff revisions. The ISO must now file the changes no later than Jan. 16, 2018 (ER16-120).

NYISO had appealed for more time to consider directives the commission set out in a Nov. 16 order, which largely accepted the ISO’s RMR proposals but asked it to clarify that a developer could propose solutions to a reliability need that are not market-based and involve generators that are already mothballed or in a forced outage. (See FERC Approves NYISO Reliability-Must-Run Plan.)

The ISO said the additional time would enable it to develop compliance revisions that fully address the directives and allow New York stakeholders an opportunity to review any changes and provide feedback. It also said the extension would help it avoid disputes with stakeholders and obtain input from its Independent Market Monitor.
