Request Summary
Grouping of resources by vintage in QCC accreditation
Co-sponsors
Description Of Issue
All resources QCC are computed each season resulting in (1) existing resource QCC values being reduced by the addition of new resources and (2) new resources being credited higher QCCs than they incrementally provide to the system. This request is to consider groupings of existing resources by vintage (2 to 5 year windows) in QCC accreditation to better align new resources with their incremental QCC to the system and retain appropriate QCC for existing investments.
Proposed Solution
While we remain open to alternate solutions, we understand the impact of the order in which resources are evaluated for QCC accreditation and believe separating vintage-based groupings to be a viable approach to establishing appropriate QCCs for existing resources apart from incremental resources.
Seasonal QCCs would continue to be studied as per the existing program however accreditation would be performed sequentially with older groupings of resources receiving their accreditation first resulting QCCs more consistent with the time of the investment for both older newer resources.
Noting vintage-based groupings should be based on inclusion in the WRAP program/studies and not the in-service date of the resources as resources may come in and out of the program.

Benefits
More appropriate accreditation for both existing and new resources. Increased certainty in resource adequacy planning by preventing accreditation leakage from over-accrediting new resources. More accurate attainment of reliability goals of the program by reducing over-accreditation new resources. Better insulated parties from impacts of other WRAP participants deployment of the resources that would otherwise diminish the value of existing investments. Align incremental resources with their incremental reliability value.
