(Uri Report Recommendation 7 and Further Study Recommendation 24)

Understanding Natural Gas Contract Risks
(Uri Report Recommendation 8)

  • NERC's Electric Gas Working Group (EGWG) developed a Fuel Assurance Reliability Guideline to help registered entities fully understand fuel supply chain risks, and offer additional conditions and constraints, especially during extreme events, to consider when performing studies. Guideline issued September 2023

Develop and Implement Actions

November 2023 - NARUC Gas-Electric Alignment for Reliability (GEAR) Working Group
(Findings from NAESB Gas-Electric Harmonization Forum, the Reliability Alliance Report developed by NGSA, INGAA and EPSA, and the FERC/NERC analyses of Winter Storms Uri and Elliott)

  • Convened by National Association of Regulatory Utility Commissioners (NARUC) and chartered in November 2023 for 15 months to "bring together state regulators and industry representatives to develop solutions to better align the gas and electric industries to maintain and improve the reliability of the gas and electric energy system."

December 2023 - NAESB gas-electric coordination business practice standards development
(Elliott Report Recommendation 5)

  • Participants prepared multiple work papers, some of which include proposed revisions to the NAESB Wholesale Gas Quadrant Business Practice Standards. Proposals for consideration include communication protocols to provide notice of weather conditions that could impact or are impacting upstream natural gas production, processing, and gathering; enhanced granularity of locational information provided in critical notices; and centralized posting of gas-electric coordination information by interstate pipelines


Grid Operations

Perform bi-directional seasonal transfer studies
(Uri Report Recommendation 20)

  • 2023: NERC's Reliability Assessment Subcommittee (RAS) completed survey of relevant entities to gain additional insight; 2024: bi-directional seasonal transfer studies for training is included in NERC's Real Time Operations Subcommittee (RTOS) workplan

Load shed coordination and training
(Uri Report Recommendations 10, 21, and 22)

  • September 2022: Electric Reliability Council of Texas (ERCOT) approved additional underfrequency load shed stage (anti-stall stage) to provide time for system operators to respond to grid conditions; Western Interconnection also incorporated anti-stall load shed stage

  • 2023: Operator training rotational firm load shed simulations - completed through NERC RTOS

  • Planned for 2023-2024: RTOS; workplan includes review and improve rotational load shed plans as needed, in collaboration with NERC RAS
