Description: This Nodal Protocol Revision Request (NPRR) modifies the Reliability Unit Commitment (RUC) engine to scale down commitment costs of fast-start Resources (<=1 hr starts) so that the RUC engine will recommend slow-start Resource commitments only if re-Dispatching of On-Line Resources and potential market-based self-commitments of fast-start Resources will not resolve the reliability issue.
Reason: Addresses current operational issues. Meets Strategic goals. Market efficiencies/enhancements.
