NOGRR078 Real-Time Security Analysis Language Clean Up to Reconcile Operating Guides with Current Operation Practice
ReasonThe ERCOT Technical Advisory Committee (TAC) directed the Planning Working Group (PLWG) of the Reliability and Operating Subcommittee (ROS) to develop planning processes that eliminate the gap between operations and planning in order to significantly reduce the amount of unmanageable constraints that have been observed in Real-Time. It is recognized that unmanageable constraints in Real-Time can arise for a variety of reasons, with the primary drivers being Outage planning and transmission planning. The PLWG has debated and submitted comments via PGRR011 to clarify and enhance the transmission planning process to narrow the gap between transmission planning and Real-Time operations. NPRR409 has been filed with a companion set of recommended enhancements to the Outage planning process that are meant to narrow the gap between Outage planning and Real-Time operations. This NOGRR is meant to clean up the Nodal Operating Guides so that it is clear that only Real-Time security studies are covered there and that the language matches current ERCOT Operations practice.

Sections Affected
1.42.2.2
Summary
This NOGRR clarifies that the only security analysis studies that remain in the Nodal Operating Guides are the Real-Time security studies (given that Outage Planning is now covered in Protocol Section 3.1.5.1 and Transmission Planning is now covered in Planning Guide Section 4, Transmission Planning Criteria); and modifies the language to match current ERCOT Operations practice related to which contingencies are enforced in Real-Time operations.
