Background

Status: Pending
Date Posted: Aug 31, 2023
Sponsor: EDF Renewables, Inc.
Urgent: No
Sections: 2 and 6.5.1.1
Description: This Nodal Protocol Revision Request (NPRR) defines Extended Action Plan (EAP), revises the defined term Remedial Action Plan (RAP), adds EAP and RAP as types of Constraint Management Plan (CMP) suitable for the market use of the ERCOT Transmission Grid, and removes language limiting the application of these CMPs to congestion issues for which there exists no feasible Security-Constrained Economic Dispatch (SCED) solution. The related NOGRR258 proposes changes that add language to allow the use of RAPs and EAPs to facilitate the market use of the ERCOT Transmission Grid, adds guardrails to ensure that topology reconfiguration requests meet basic reliability and economic criteria, and defines the process for submission, review, and approval of EAPs. This NPRR and NOGRR258 leverage ERCOT’s existing CMP process to quickly mitigate critical transmission congestion impacts by establishing a scalable process for topology reconfiguration requests that is transparent, predictable, equitable, workable, reliable, and compatible with existing planning processes. ERCOT already leverages topology optimization in the CMP processes. Since NPRR529, Congestion Management Plan was introduced in 2013 with the limitations that this NPRR proposes to revise, the power industry has evolved and there have been technological improvements that make transmission topology reconfigurations a powerful option to mitigate congestion beyond just use cases for which there is no feasible SCED solution.
Reason: Strategic Plan Objective 2
