After receiving pan-sector feedback from stakeholders asking for more time to review NYISO's proposed changes to the reliability planning process, the ISO said it would delay proposing tariff language.

NYISO is proposing to use a set of multiple scenarios rather than relying on a single base case in its Reliability Planning Process to avoid study-by-study fluctuations in determining reliability needs.
