First name, email and what you're interested in are all we need to get moving. Everything else, including drawings or an RFP, is optional.
Transmission Planners run studies with your models. Reliability Coordinators and Transmission Operators run the grid with your ratings. When a model does not match plant behavior, planning and operating decisions are made on the wrong basis. When a rating is higher than the most limiting piece of equipment, the grid can be operated beyond what the facility can actually carry.
That is why the ERO has made model quality — particularly for inverter-based resources — and facility ratings recurring priorities. Both are engineering problems first: they are solved with test data, simulation, nameplate verification and field walk-downs, then recorded as compliance evidence.
Always work to the version in effect for your facility and audit period — several of these standards are being revised under FERC Order No. 901, particularly for inverter-based resources.
| Standard | What it addresses | Engineering evidence we produce |
|---|---|---|
| MOD-025 | Verification and reporting of generator real and reactive power capability | Test plans, staged or operational test data, capability curves, data reporting to the Transmission Planner |
| MOD-026 | Verification of excitation control system or plant volt/var control models | Model parameter review, test or disturbance data, simulated vs measured comparison, verification report |
| MOD-027 | Verification of turbine/governor and load control or active power/frequency control models | Frequency-response testing or event data, model tuning, verification report |
| MOD-031 | Demand and energy data | Data compilation and submission support for applicable entities |
| MOD-032 | Data for power system modeling and analysis | Steady-state, dynamic and short-circuit data prepared to the PC/TP data requirements; EMT models where required |
| MOD-033 | Steady-state and dynamic system model validation | Comparison of planning models against actual system events, documented validation process |
| FAC-001 / FAC-002 | Facility interconnection requirements and studies | Interconnection study models, requirement documentation and study-coordination records |
| FAC-008 | Facility Ratings | Ratings methodology, equipment-level ratings database, most-limiting-element determination, as-built reconciliation |
Test planning, witness support, data analysis and capability-curve reporting for synchronous and inverter-based plants.
Model parameterization, benchmarking against measured response and verification reports in PSS®E and PSLF.
PSCAD™ plant models built from OEM inverter models, collector systems and plant controllers, benchmarked to positive-sequence models.
Steady-state, dynamic and short-circuit data prepared to each Planning Coordinator’s and Transmission Planner’s requirements — PJM, CAISO, ERCOT, MISO, SPP, WECC and others.

A methodology that covers every equipment type in the series path, with the assumptions a reviewer will ask about.
Equipment-level normal and emergency ratings, most-limiting-element determination and change control.
Field and drawing verification that ratings reflect the installed equipment — CTs, jumpers, switches, breakers, conductors and relay limits.
Facility Ratings are one of the most persistent compliance issues in the industry because they depend on every piece of equipment in the series path — and equipment changes over time. A single replaced CT, a new jumper or an upgraded relay can change the most limiting element without anyone updating the rating.
For inverter-based resources, model accuracy depends on the inverter firmware, the power plant controller, the collector system and the settings actually installed. Generic or outdated models are a recognized ERO concern, and planning entities increasingly require EMT models alongside positive-sequence models.
We build and verify IBR models from OEM data and site settings, benchmark positive-sequence against EMT behavior, and update both after augmentation, repowering, firmware changes or controller tuning.
Nameplates, OEM models, settings, test reports, one-lines, drawings and the PC/TP data requirements that apply to you.
Confirm the model and ratings inputs reflect installed equipment and in-service settings.
Plan staged tests or use disturbance and operational data for capability and model verification.

Commissioning changes, firmware updates and tuning leave the submitted model behind the plant.
A parameter check alone does not show the model reproduces actual plant response.
Planning entities increasingly reject submissions where the two models behave differently.
Omitted components — jumpers, CTs, relays, wave traps — can hide the true limiting element.
Equipment replacements quietly change the most limiting element.
Each PC and TP publishes its own requirements; a submission built for one region may not satisfy another.
We build and run PSS®E, PSLF and PSCAD™ models ourselves — the same work that goes into interconnection studies.
Experience with PJM, CAISO, ERCOT, MISO, SPP and WECC model submission processes.
Substation design experience means we know where the limiting element usually hides.
Every verification and rating record is written so a Regional Entity reviewer can trace it.
Model verification demonstrates that the models used for your generating facility — capability, excitation or volt/var control, and governor or active power/frequency control — reproduce the actual behavior of the plant. MOD-025, MOD-026 and MOD-027 set the requirements for this verification.
Verification needs measured response to compare against the model. That can come from staged tests or, where the standard allows, from recorded disturbances and operational data. We help select the approach that meets the requirement with the least operational disruption.
MOD-032 requires entities to provide modeling data to their Planning Coordinator and Transmission Planner according to the data requirements those entities publish. The format, content and schedule vary by PC and TP.
Positive-sequence models cannot fully represent fast inverter controls and weak-grid behavior. Many planning entities now require PSCAD™ EMT models for inverter-based resources, benchmarked against the positive-sequence model.
FAC-008 requires Generator Owners and Transmission Owners to have a documented Facility Ratings methodology and to establish Facility Ratings consistent with it, reflecting the most limiting applicable equipment rating.
Ratings depend on every piece of equipment in the series path, and that equipment changes over time. Without change control and periodic reconciliation, ratings drift from the installed equipment.
Yes. Where drawings and records cannot be relied upon, we support field verification of nameplates and equipment to reconcile the ratings database with what is installed.
Yes. Adding storage, replacing inverters, changing firmware or retuning plant controllers can change plant behavior and capability. Models, data submissions and, often, ratings should be updated.
Order No. 901 directed NERC to develop new or revised standards for inverter-based resources, including model verification and data requirements. Model verification standards are being revised as part of that work, so the applicable version and its effective date should be confirmed for each facility.
No. This service covers Operations & Planning modeling and ratings standards. CIP cybersecurity is a separate discipline.
Send us your current models, test reports and ratings database. Keentel will show you where they diverge from the installed equipment — and fix it before your Planning Coordinator or auditor does.
