Summary

This Nodal Protocol Revision Request (NPRR) replaces the defined term Maximum Daily Resource Planned Outage Capacity (MDRPOC) with Resource Planned Outage Limit (RPOL) to align with the actual calculated RPOL as described in Section 3.1.6.13; adds the maximum duration of a proposed Transmission Facility Outage that may be approved with a described lead time to align with current Outage Coordination practices; defines the conditions that ERCOT may accept the Resource Planned Outage request if it could cause the exceedance of Resource Planned Outage Limit; and clarifies that, like any other Resource, Energy Storage Resources (ESRs) submit Outages pursuant to Sections 3.1.4.1 and 3.1.4.7.
