Current Operating Plan (COP)

The following diagram describes the structure of a Current Operating Plan (COP), where the COP provides a schedule for a resource:

AS Capacity Structure

COP submissions are never cancelled, as a COP must be submitted. A resubmission of a COP overwrites the previous submission. On submission, the following table describes the items used for a COP:

ONSC - Resource is On-Line operating as a synchronous condenser and available to provide Responsive Reserve (RRS) and ECRS, if qualified and capable, and for commitment by RUC, but is unavailable for Dispatch by SCED. For SCED, Resource Base Points will be set equal to the telemetered net real power of the Resource available at the time of the SCED execution
