A Coordinated Electric System Interconnection Review—the utility’s deep-dive on technical and cost impacts of your project.

As solar, wind, and battery-based Inverter-Based Resources (IBRs) rapidly expand across the Bulk Power System (BPS), NERC has identified reliability risks due to poor model quality. On June 4, 2024, the North American Electric Reliability Corporation (NERC) issued a Level 2 Industry Recommendation Alert addressing widespread IBR dynamic modeling deficiencies.

At Keentel Engineering, we help Generator Owners (GOs), Transmission Planners (TPs), and Planning Coordinators (PCs) align with these NERC recommendations, supporting compliance, planning accuracy, and system stability across all interconnection and reliability study phases.

What is the alert about?
To address systemic inaccuracies in dynamic IBR models.
Who must respond?
GOs, TPs, and PCs with BPS-connected IBRs.
What models are required?
PSPD, EMT, and standard library (case-dependent).
What are equipment-specific models?
Custom, validated inverter models matching site behavior.
Why are standard models not enough?
They lack customization and dynamic fidelity.
How are models validated?
Through benchmarking and performance comparison.
What’s in a benchmarking report?
Comparisons of model types vs. real equipment behavior.
When must models be updated?
After any hardware/firmware/control change.
What are ‘qualified changes’?
Changes impacting behavior per FAC-002-4.
Impact on interconnection studies?
Only validated models are accepted near study zones.
Is EMT always required?
No, only for EMT-driven studies.
TP/PC responsibilities?
Define requirements, verify submissions.
Can vendors help?
Yes, they should provide validated parameters and models.
Is the alert enforceable?
Yes under NERC’s Rules of Procedure (non-compliance may be flagged).
How can Keentel help?
We provide end-to-end validation, worksheet support, and model integration for compliance.

In 1995, Sandip (Sonny) R. Patel earned his Electrical Engineering degree from the University of Illinois, specializing in Electrical Engineering . But degrees don’t build legacies—action does. For three decades, he’s been shaping the future of engineering, not just as a licensed Professional Engineer across multiple states (Florida, California, New York, West Virginia, and Minnesota), but as a doer. A builder. A leader. Not just an engineer. A Licensed Electrical Contractor in Florida with an Unlimited EC license. Not just an executive. The founder and CEO of KEENTEL LLC—where expertise meets execution. Three decades. Multiple states. Endless impact.
