NERC Compliance Modeling for FERC Order 901 & MOD Standards

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

In the ever-evolving landscape of power system management, maintaining compliance with NERC standards is not optional—it’s essential. The emergence of renewable energy resources and inverter-based technologies has dramatically transformed the operational dynamics of the Bulk Power System (BPS). To support this transformation, Keentel Engineering offers advanced NERC compliance services tailored to help Generator Owners (GOs), Transmission Owners (TOs), and other regulated entities navigate complex requirements under FERC Order 901, MOD-032-2 modeling, and MOD-026-2 compliance standards.

Keentel Engineering’s NERC compliance modeling services address key standards such as MOD-032-2, MOD-026-2, and MOD-033, helping Generator and Transmission Owners implement FERC Order 901 requirements effectively. Whether you need IBR compliance modeling, assistance with PRC-002-5 disturbance data, or MOD-032-2 model validation, we provide tailored solutions. Our engineers support clients with FERC 901 ibr standards, mod-026-2 compliance, and mod-032-2 modeling for real-world accuracy. Even complex needs like EMT model validation services or mod-033 audit readiness are handled with precision.

What is a NERC compliance service?
A NERC compliance service is a suite of engineering consulting and modeling solutions that ensure utilities, GOs, TOs, and other entities meet mandatory reliability standards set by NERC.
Why is NERC compliance important?
NERC compliance guarantees the reliable operation of the Bulk Power System (BPS), prevents grid disturbances, and helps stakeholders avoid significant financial penalties.
What is FERC Order 901?
FERC Order 901 is a federal directive mandating updated modeling and validation practices—particularly for Inverter-Based Resources (IBRs)—to enhance grid reliability.
What is the difference between model verification and validation?
Model Verification confirms that the model’s design aligns with NERC and IEEE requirements.
Model Validation compares simulation outputs against real disturbance data (e.g., from PRC-002 and PRC-028) to ensure accuracy.
Which entities need to comply with MOD-026-2?
Generator Owners with new or existing IBRs commissioned after the effective date must comply with MOD-026-2 for model verification and validation.
What does MOD-032-2 address?
MOD-032-2 defines a uniform framework for collecting model data for IBRs and DERs across all planning regions, including the new Attachment 1 requirements.
How does MOD-033 ensure system reliability?
MOD-033 mandates end-to-end system model validation, comparing dynamic and steady-state simulations against actual performance data to guarantee planning models reflect real behavior.
What are Inverter-Based Resources (IBRs)?
IBRs are energy assets—such as solar PV, wind turbines, and BESS—that interface with the grid via power electronics, requiring specialized modeling and compliance under PRC-029, MOD-032, and related standards.
Who benefits from Keentel’s NERC compliance services?
Utilities, GOs, TOs, Distribution Providers, and any NERC-registered entities gain from our turnkey compliance solutions, ensuring audit readiness and operational resilience.
What is EMT modeling and who needs it?
EMT modeling (Electromagnetic Transient) involves high-fidelity PSCAD or similar simulations for IBRs to assess transient behavior during faults and system events.
Are legacy systems covered under the new NERC modeling rules?
Yes. Even legacy assets lacking OEM support must be modeled or justified for exemption under MOD-026-2 and MOD-032-2 guidelines.
What is Attachment 1 in MOD-032?
Attachment 1 is the detailed data sheet specifying required information—such as control parameters and protection settings—for all DER, demand, and IBR models.
What are “Acceptable Models” under ERO criteria?
“Acceptable Models” meet the ERO’s performance and usability benchmarks, ensuring consistency and comparability across interconnection-wide studies.
How is model performance evaluated?
Performance is validated by comparing simulation outputs against recorded disturbance data from PRC-002-5 and PRC-028-1 monitoring equipment.
How long do I have to comply with new MOD-032-2 changes?
Compliance timelines extend up to 36 months post-effective date, depending on FERC approval and the specific implementation phase (R2–R4).
Do unregistered IBRs need to be modeled?
Yes. MOD-032-2 requires modeling for all IBRs above threshold capacities, regardless of formal NERC registration.
What’s Keentel’s approach to phased compliance?
We develop customized roadmaps aligned with FERC milestones and COD (Commercial Operation Date) requirements for each standard’s phase-in.
What if I lack disturbance data for model validation?
Keentel assists in acquiring and interpreting disturbance recordings from PRC-002 and PRC-028 monitoring equipment.
Can Keentel support me during a NERC audit?
Absolutely. We deliver comprehensive compliance documentation, technical reports, and expert defense during NERC audits.
How are system models validated interconnection-wide?
Validation is performed collaboratively across all Planning Coordinators’ footprints to ensure regional consistency under MOD-033.
Does MOD-033 apply to real-time operations?
No—MOD-033 applies to offline models used by planners, not to real-time operational systems.
What if my model is deemed unacceptable?
We reconfigure, retest, and resubmit your models for ERO approval, ensuring full compliance.
What tools does Keentel use for modeling and validation?
Industry-approved platforms such as Siemens PSS®E, PSCAD, and other benchmarking software ensure model accuracy and compliance.
What happens after model validation?
Validated models are updated, resubmitted, archived, and integrated into ongoing grid operations and future audits.
