Deliverability is an essential element of any resource adequacy assessment. LSE compliance with resource adequacy procurement obligations will be affected by the ability of their procured supplies to serve Load under peak conditions. Therefore, an effective deliverability study is essential in resource planning so that LSEs are able to their resources to determine if they ‘count’ are satisfying the required Reserve Margins. The deliverability of Generation to the aggregate of Load measures the capability of the transmission system given the dispatch of other proximate Generation resources to deliver power output from a particular Generator to Load in the ISO Control Area during peak Demand conditions. A resource whose output is not fully deliverable will have the capacity that it may offer for resource adequacy purposes reduced. Consequently, ISO has developed a deliverability study to assess deliverability of Generation to serve Load in the ISO Control Area. This deliverability assessment of Generation to the aggregate of load is performed through both annual assessments to measure general system changes and for new Generating Facilities through the Large Generator Interconnection Procedure. ISO performs Deliverability Assessments consistent with the timeline of Generator Interconnection Procedure (GIP). Table 1 outlines the studies to be done in each GIP study cycle: Table 1: Deliverability Assessment Start End Cluster Phase I June October Cluster Phase II January July Annual Full Capacity June August Deliverability Option1 The annual full capacity deliverability option for Generating Facilities previously studied as Energy-Only Deliverability Status starts in 2012. Pursuant to Section 6.5.2 of the Generator Interconnection Procedure (GIP), Appendix Y of the ISO Tariff, ISO will conduct a Deliverability Assessment in the Phase I study to determine: Preliminary Delivery Network Upgrades required to provide the Generating Facility with Full Capacity Deliverability Status. MW of deliverable generation capacity for the group of generators that contribute to the same transmission constraints if the highest cost Delivery Network Upgrade component were removed from the preliminary Delivery Network Upgrade plan. The Interconnection Customer can choose to move forward into the Phase II study either confirming the same deliverability status as in Phase I or changing the deliverability status from
