NOGRRs for Review and Language Changes:


  • 149NOGRR Revision to Definition of Transmission Operator. This Nodal Operating Guide Revision Request (NOGRR) revises the definition of "Transmission Operator" to establish a "Bright Line" threshold (annual peak MW) below which a Distribution Service Provider (DSP) owning no transmission or generation facilities, and who is not provided or offered Transmission Operator (TO) services from their incumbent Transmission Service Provider (TSP) or wholesale power supplier, would be exempted from having to procure designated TO services from a third-party provider. The "Bright Line" threshold being recommended is 25 MW. [Schneider Engineering]
  • 150NOGRR Alignment with NPRR747, Revision of Voltage Control Requirements.  This Nodal Operating Guide Revision Request (NOGRR) relocates language concerning voltage support obligations that currently resides in an ERCOT procedure document but that should be moved to the Operating Guide so that the requirements are recognized as binding.  Based in part on discussions at the April 8, 2015 Voltage Workshop, this NOGRR also allocates each of various voltage support responsibilities to the appropriate Entity.  Additionally, this NOGRR clarifies that the ERCOT Transmission Operator (TO) has the authority to instruct a Qualified Scheduling Entity (QSE) to modify its Generation Resource’s Voltage Set Point.  Additional edits are intended to better synchronize language with the North American Electric Reliability Corporation (NERC) Reliability Standards. [ERCOT]
  • 151NOGRR Alignment with NPRR748, Revisions associated with COM-002-4 and Other Clarifications Associated with Dispatch Instructions. This Nodal Operating Guide Revision Request (NOGRR) aligns the Operating Guides with changes made in NPRR748 and also provides consistency, transparency, and clarification related to communication protocol in the ERCOT Region. [ERCOT]
  • 152NOGRR Restore Synchrony between Contingency Planning for Minimum Level of Responsive Reserve Service and Real Time Contingency Analysis. Align consideration of the simultaneous loss of the South Texas Nuclear Project (STP) as a credible single contingency for purposes of determining the minimum amount of Responsive Reserve (RRS) as it is currently used in the Real-Time Contingency Analysis (RTCA). [Apex et al]
  • 747NPRR Revision of Voltage Control Requirements. This Nodal Protocol Revision Request (NPRR) proposes new definitions related to Voltage Profiles, defines various entities’ responsibilities related to Voltage Support, and also clarifies that the interconnecting Transmission Service Provider (TSP) (or its designated agent) may modify a Generation Resource’s Voltage Set Point).  This NPRR addresses issues raised at the April 8, 2015 Voltage Workshop.  [ERCOT]
  • 748NPRR Revisions associated with COM-002-4 and Other Clarifications Associated with Dispatch Instructions. This Nodal Protocol Revision Request (NPRR) aligns with North American Electric Reliability Corporation (NERC) Standard COM-002-4, Operating Personnel Communications Protocols, and provides language clarification for Dispatch Instructions and procedures.  [ERCOT]
