Early 2016 – Capacity Procurement Mechanism Replacement (CPM) Project Info Details/Date Competitive Solicitation Process (CSP): CSP replaces the existing administrative price process for annual, monthly and intra-monthly CPM events for flexible and generic RA capacity. CSP will cover all events that allow the ISO to procure additional capacity. CIRA: − Bid Submittal system for SCs to submit capacity bids (not an existing bid type) − Capacity bids to implement new validation rules (not an existing bid type) − Capacity Bid submittal to be on a yearly, monthly, and intra-monthly level − LSE/LRA deficiency calculation to be performed for CSP for Generic and Flexible RA data − Existing CPM calculation to be deprecated for trade dates after the effective date of implementation. − Manage import allocation and bilateral trades of import allocation Application Software Changes Settlements: Settlements will need new CPM formulas that will result in charge code impacts. Reporting: If an annual or monthly CPM occurs greater than two times (over a rolling 24 month period) or more than 50% of the LSE’s RA requirement is CPMed, a report must be given to Market Participants. OASIS: − Publish all finalized offers into the competitive solicitation process on a rolling five-quarter delay. (Deferred) − Solicitation for soft offer cap. Timeline for submittal needs to be defined. − Submittal process for annual/monthly CPM bid submittal Business Process Changes − New business process for amount of capacity being relied on (non-RA from partial RA) − New process for Competitive Solicitation Process (annual/month/intra-monthly) Page 61
