The ISO deliverability assessment methodology was developed for generation interconnection study purposes and is used in support of resource adequacy assessments. This methodology, last modified in 2009, has largely remained unchanged since its initial development in 2004. Through this initiative, the ISO will consider revisions to the methodology given the significant changes in the composition of the existing generation fleet and further changes anticipated over the forecast horizon.
Outcome: The ISO submitted the initial filing on Jan. 1, 2020 to implement three deliverability enhancements for interconnection customers. FERC responded with a deficiency letter on Feb. 28, 2020, with instructions to submit a compliance filing. The ISO did so on June 3, 2020 and FERC accepted on Sept. 11, 2020.
