NPRR394  Outage Reporting

Approved sponsor Edison Mission posted 2011-07-14 ercot.com
ReasonThe 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."
