For utilities and transmission owners

Independent verification of the large load models you receive.

You carry the study risk of a model you did not produce. Nyquist gives planning and protection teams an independent, measured view of how large computational loads actually behave.

What we provide

Evidence your planners can defend.

Submission review

Independent review of customer-supplied dynamic models and questionnaire data against measured behavior, with specific parameter findings.

Commissioning measurement

Measurement plans and analysis for staged energization, so models are validated with real data before the site reaches full load.

Ride-through investigations

Root cause analysis when a facility trips or behaves unexpectedly during a disturbance, built on recorded data from both sides of the fence.

Requirement checks

Automated checks of measured performance against your own large load technical requirements, from ride-through envelopes to ramp and oscillation limits.

The gap

Most entities still lack a process to commission and verify large loads.

Large load models are often built from datasheets and generic parameters. Recent events show those models can miss the behavior that matters most: whether load rides through, transfers to backup or trips, and how it comes back.

FAQ

For planning and protection teams.

Can Nyquist review a model a customer has already submitted?

Yes. We compare submitted large load models against measured behavior from the site or from similar facilities, and flag parameters that do not hold up, such as transfer thresholds, lockout logic and recovery timing.

Do you work for the utility or the data center?

Either, and that is the point. We are an independent third party with no equipment to sell and no load to control, so the evidence holds up for both sides.

Can you support commissioning?

Yes. We provide commissioning measurement plans and analysis so the first energization produces data that can validate the model before full load.

Give your planners a measured view of large loads.

We work with a small number of utility partners on submission review and commissioning measurement. A 30 minute demo covers the platform and how it fits your process.
