ReasonAddresses current operational issues
Created2020-07-16

Sections Affected
5.5.2
Summary
This Nodal Protocol Revision Request (NPRR) establishes a requirement for Qualified Scheduling Entities (QSEs) to notify ERCOT of physical limitations on their Resources’ ability to start that are not able to be modeled in the Reliability Unit Commitment (RUC) software and excuses compliance with portions of RUC Dispatch Instructions that violate physical limitations of Resources if the QSE has previously notified ERCOT of the limitation. The NPRR also establishes a requirement that ERCOT extend a RUC commitment in order to honor the minimum run-time limitation of a Resource when a physical limitation delays the Resource’s ability to reach its Low Sustained Limit (LSL).
