Resource adequacy one-for-many manual substitution (completed)

Outcome: On Apr 01, 2014, the ISO implemented a manual process that allows scheduling coordinators to substitute, under limited conditions, capacity for resource adequacy resources on forced outages. This will help to avoid availability shortfalls. The ISO is currently developing automated functions to resolve the current system limitations that prevent substituting a single resource for more than one resource on outage. In the meantime, the manual process will be used. — Implemented Apr 01, 2014; FERC approval: May 30, 2014; Tariff amendment filing: Jan 30, 2014 (ER14-1220)

Scheduling coordinators can substitute capacity for resource adequacy resources on forced outages to avoid potential availability shortfalls. The ISO is developing automated functions to resolve current system limitations preventing the substitution of a single resource for more than one resource on outage. Until the solution is deployed, the ISO proposes a manual process to accommodate this one-for-many substitution under a limited set of conditions.
