1. What is the deadline for the Cold Weather Generator Data Report?
All Generator Owners (GOs) must submit the Extreme Cold Weather Temperature (ECWT) report by May 15, 2025. This year, NERC is allowing a grace period until June 15, 2025 for BES units.
2. Who is required to submit the ECWT data report?
Only NERC-registered Generator Owners with BES facilities in the United States are required to submit. Submissions must be completed by the Primary Compliance Contact or Entity Administrator.
3. What resources are available to help GOs complete the ECWT worksheet?
A revised worksheet with instructions
Training videos and materials
ECWT FAQ document
All are available on the NERC Cold Weather Data Request page.
4. What modeling standards ballots are currently open?
Project 2022-02 – Uniform Modeling Framework for IBRs (closes May 16, 2025)
Project 2021-01 – System Model Validation with IBRs (closes May 21, 2025).
5. What did the IBR Model Quality Alert reveal?
The April 2025 aggregated report revealed:

66% of protection settings do not use full inverter capability
Systemic mismatches in model data formats (.dyr/.dyd, field data, and manual entries)
Insufficient use of equipment-specific models for interconnection studies.
6. What are the key recommendations for improving IBR modeling?
Submit both standard library and user-written PSPD/EMT models
Maintain up-to-date and site-specific model parameters
Align models with FERC LGIP/SGIP interconnection standards
Enhance coordination with OEMs and TPs/PCs.
7. Why is reactive power capability reporting important?
20% of solar PV sites are operating under a “triangle” power factor limitation (0.95 PF), reducing the available reactive support to the grid. NERC urges accurate modeling to reflect true inverter capabilities.
8. What is the Align system outage schedule?
Planned maintenance for the Align system is scheduled from:
May 16, 8:00 p.m. ET to May 17, 4:00 p.m. ET
System updates will be outlined in Release Notes 7.2.0.
9. Which standards are scheduled for enforcement in 2025–2027?
July 1, 2025: IRO-010-5, TOP-003-6.1
Oct 1, 2025: TOP-002-5
Apr 1, 2026: TPL-008-1, CIP-003-9
Jul 1, 2026: CIP-012-2
Apr 1, 2027: BAL-007-1.
10. Where can I find registration links for upcoming NERC events?
You can access all events and register through the official NERC Calendar, including:

IBR Milestone 3 Workshop (June 3–5)

Summer Reliability Webinar (May 14)

In 1995, Sonny Patel earned his Electrical Engineering degree from the University of Illinois. But degrees don't build legacies — action does.

Utility. Generator. Regulator. Consultant. Few engineers have seen all four seats. Fewer still have sat in them.His experience spans nuclear, hydro, conventional generation, renewables, oil and gas, mining — and today's data centers, where he is authoring a three-book series on data center design. He is a Licensed Professional Engineer in six states and a Licensed Electrical Contractor in Florida (Unlimited EC) — he doesn't just design the work; he's qualified to stand behind its execution.Today, as Founder and CEO of Keentel Engineering, Sonny leads 51 engineers delivering substation design, power system studies, NERC compliance, and commissioning — done right, coast to coast.Three decades. Every side of the table. One standard: accountable engineering

In 1995, Sonny Patel earned his Electrical Engineering degree from the University of Illinois. But degrees don't build legacies — action does.

For three decades, he has worked the power industry from every side of the table: 16 years as a utility engineer at Exelon/Commonwealth Edison; generation leadership across hydroelectric, industrial steam turbine, and a 9 GW renewable fleet; NERC Regional Entity Senior Compliance Engineer and Audit Team Lead, auditing some of the nation's largest utilities; and testing and commissioning lead on equipment up to 765 kV — the very top of the North American grid.Utility.
