Holistic review of the resource sufficiency evaluation Stakeholders have requested a holistic review of the resource sufficiency evaluation. They state the EIM footprint has changed since the EIM implementation in 2014 and therefore the resource sufficiency evaluation approach should be evaluated. The ISO plans to complete a holistic review of the resource sufficiency evaluation during the extension of the day-ahead market to the EIM (EDAM), which is scheduled to start in the middle of 2019. Any EDAM design will require a day-ahead resource sufficiency evaluation. In order to introduce a day-ahead resource sufficiency evaluation, the ISO will need to align the day-ahead resource sufficiency evaluation with the real-time resource sufficiency evaluation. This is the appropriate time and place for a holistic review. Stakeholder Engagement The ISO has appreciated stakeholder engagement and comments during the April 30 and July 19, 2018 workshops. At this time the ISO is addressing items that were prioritized by stakeholders: freezing transfers for fifteen-minute intervals for failure of the flexible ramping test, introduction of a 1% tolerance band for the flexible ramping test, and a new approach to calculate the resource sufficiency evaluation requirement. None of these items require tariff changes and therefore can be implemented with the business practice manual (BPM) change process. Therefore, the ISO will not be pursuing a stakeholder initiative for the energy imbalance market resource sufficiency evaluation at this time. The ISO will discuss this paper during a stakeholder conference call on September 26, 2018. The ISO requests that any outstanding questions or comments are discussed at that time.
