Extension for LCL Cooling Load Ride-Through Compliance |
This Nodal Operating Guide Revision Request (NOGRR) permits a Large Computational Load (LCL) to achieve compliance with the applicable ride-through requirements within 365 days after its in-service date where the LCL’s cooling load is unable to satisfy such requirements as of the in-service date due to ongoing design and manufacturing limitations, including constraints associated with vendors’ continued adaptation of chiller and Variable Frequency Drive (VFD) equipment to the applicable standards. |

Update to Section 1.5.4, ERCOT Severe Weather Drill |
This Nodal Operating Guide Revision Request (NOGRR) revises Section 1.5.4 to align language for the annual severe weather drill with current practices. Specifically, the revision: (1) replaces references to the Operations Working Group (OWG) in paragraphs (1)(a) and (1)(c) of Section 1.5.4 with references to “the working group designated by the Reliability and Operations Subcommittee (ROS),” reflecting that ERCOT develops the annual severe weather drill with the Working Group designed by ROS, currently, the Operations Training Working Group (OTWG); (2) clarifies the obligation in the existing language by relocating the scheduling and communication-function testing of the primary or backup control centers from paragraph (1) of Section 1.5.4 to paragraph (2); and (3) removes obligations in paragraph (3) of Section 1.5.4 that are more appropriately addressed in the applicable stakeholder group’s Scope document. |
