The HASP run for HE02 may be missed. During the maintenance outage window, internal resources which have Resource Adequacy capacity should follow their last good RT ADS dispatch. Intertie resources that do not receive a HASP ADS dispatch should follow their day ahead Residual Unit Commitment schedules or operator instructions. For ancillary service awards, if you do not receive a RT instruction, follow your day ahead awards.


Resources which are scheduled to shut down or transition during this outage should contact ISO RT system operations to get approval prior to transitioning or shutting down.
