Extreme Cold Weather Grid Operations, Preparedness, and Coordination SAR

Extreme Cold Weather Grid Operations, Preparedness, and Coordination SAR

The Standards Authorization Request (SAR) related to cold weather grid operations submitted October 6, 2021, began a series of technical document development, revisions to existing standards, and creation of new standards. While state entities like the Texas Public Utility Commission have taken immediate steps to require generators and transmission service providers to formulate plans for reliable cold weather operations, this SAR begins the process of including cold weather operations reliability in the NERC standards.

The SAR includes nine recommendations summarized below along with their implementation timeline. These recommendations have an implementation timeline before winter 2023/2024. Some recommendations were steered by NERC-issued technical documents or guides while some were included in updates to current or revised NERC Reliability Standards. Some will be included in new NERC Reliability Standards with corresponding revisions and retirements of the existing standards. While mainly targeted to Generator Owners, due to their knowledge of their generation systems, the changes also relate to processes performed by Transmission Operators and Balancing Authorities in their functions related to transmission system reliability.

The nine recommendations are summarized below with an update on current status:

Several Reliability Standards will be updated moving into this winter 2023/2024 season. If you have ever considered monitoring the standards development process for issues directly related to how you plan, operate, and maintain your piece of the grid, now is the time. This SAR has had near- and long-term effects that will affect budgets, staffing, and training for years to come.

As we have said before, this process is completely transparent. All the details of any new or revised standard will be posted, opinions and reviews will be solicited, and responses to those opinions and reviews will be posted.

It’s also worth noting the section of the SAR that addresses the Cost Impact Assessment remains unknown.

We will continue to monitor and provide insight into this SAR as it moves forward, but you know the specifics of your equipment and systems better than anyone. Make sure your potentially unique issues are addressed.
