Background

Status: Approved
Date Posted: Jul 14, 2011
Sponsor: Edison Mission
Urgent: No
Sections: 2.1, 3.1.4.8
Description: This Nodal Protocol Revision Request (NPRR) clarifies that material derates for Resources are greater than 10MW.
Reason: The proposed language clarifies the Nodal Protocols and relieves Market Participants and ERCOT from undue distraction for reporting that provides little value to system reliability. Section 8.6.3, Deratings, of the zonal Protocols had similar language that apparently was overlooked as the Nodal Protocols were developed. "The Resource Entity or its designee must enter material deratings that are expected to last more than forty-eight (48) hours in the ERCOT Outage Scheduler. A derating is considered to be material when the Resource’s capability is reduced by the greater of ten percent (10%) or 10MW due to the loss of auxiliary equipment or other known conditions. ERCOT will consider the Resource’s capability as the lesser of the latest seasonal net capability test, or the asset registration submittal."
