NOGRRs for review and language changes:

  • 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] (language review)
  • 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] (language review)
  • 153NOGRR, Maintenance of Duplicate EEA Language via Alignment NOGRR Process. This Nodal Operating Guide Revision Request (NOGRR) creates a new process for maintaining alignment of the Energy Emergency Alert (EEA) language between the Protocols and Nodal Operating Guides via "Alignment NOGRRs".This NOGRR is in response to the 5/28/15 Technical Advisory Committee (TAC) decision that EEA language be maintained in both the Protocols and Nodal Operating Guides; and that a process be developed to ensure consistency. (Impact Analysis review)
  • 154NOGRR, Alignment with NPRR755 and Requirements for ERCOT WAN Installation and Exchange of Resource-Specific XML Data. This Nodal Operating Guide Revision Request (NOGRR) clarifies the installation requirements for the ERCOT Wide Area Network (WAN), allows a Qualified Scheduling Entity (QSE) to designate an agent for purposes of connecting to the ERCOT WAN, and requires ERCOT and Market Participants to use the ERCOT WAN to exchange Resource-Specific Extensible Markup Language (XML) Data (language review)
  • 155NOGRR,Voltage Ride-Through Requirements Clarification.  This Nodal Operating Guide Revision Request (NOGRR) clarifies Voltage Ride-Through (VRT) performance requirements for all Generation Resources immediately following a fault.  This NOGRR stipulates that, in addition to remaining On-Line and connected to the transmission system following a fault, Generation Resources must also maintain real power. [ERCOT] (language review)
  • 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] (associated with NOGRR150)
