Background

Status: Approved
Date Posted: Mar 14, 2011
Sponsor: ERCOT
Urgent: No
Sections:
Description: This System Change Request (SCR) modifies the existing Current Operating Plan (COP) validation to use the highest Emergency Ramp Rate value from the registered Emergency Ramp Rate curve as an input to the COP validation check of Responsive Reserve (RRS) responsibility.
Reason: Currently, the Emergency Ramp Rate value that is used in the COP validation check of RRS responsibility is limited by the COP High Sustained Limit (HSL) for the same hour, which can cause some COP submissions to be rejected even when the RRS Responsibility is valid.
