VYUH GRID ASSURANCE

Unlock more grid capacity, with the evidence to stand behind it.

A conductor study is not a facility rating. We verify the complete line, from terminal equipment and clearances to records and approval obligations, before a rating change is approved. When the evidence conflicts or goes missing, the decision stops and reaches your engineer with the reason attached.

NORTH–CENTRAL 138 KV LINE 1

900 A → 1,200 A

Conductor capabilityThe linked line-design report supports 1,200 A, subject to its documented assumptions.SUPPORTED

Terminal equipmentTwo systems give the north disconnect two different ratings. No field record settles it.HOLD

Road-crossing clearanceAt the proposed condition, span 118–119 clears County Route 12 by 21.2 ft against 22.4 ft required.FAIL

Change obligationsThe planning model, operations model, effective date, and final approval are not in place.INCOMPLETE

NOT READY FOR APPROVAL

The conductor passed. The complete line did not.

THE PROBLEM

A power line is only as capable as its weakest constraint.

The conductor may carry more while a disconnect, a jumper, a road crossing, or a record nobody revised still limits the complete facility. The proof is scattered across the line-design model, GIS, the asset system, one-lines, datasheets, spreadsheets, and prior approvals. Today, engineers reconcile it by hand.

EVIDENCE COMPLETENESS

Are the studies, records, and approvals all present and linked?

ASSET IDENTITY

Is the disconnect in EAM the same one on the one-line?

LIMITING EQUIPMENT

Was every series element evaluated, not just the conductor?

RATING CONSISTENCY

Do the worksheet, one-line, EAM, and datasheet agree?

CLEARANCE SUPPORT

Does a valid study support the proposed conductor condition?

CHANGE OBLIGATIONS

Have the planning and operations models caught up?

NERC's 2026 compliance plan ties incorrect facility ratings to unknown operating states, line sag beyond design limits, equipment damage, fires, and widespread outages. It also notes that ratings feed the very models used to plan for load growth. Getting the rating right is now a capacity strategy, not just a compliance duty.

THE PILOT

Start with completed projects, not live grid operations.

Eight weeks, one line family, 10–20 historical rating changes, read-only records. We measure whether Vyuh reproduces known findings, cites the right requirements, catches real record conflicts, abstains when it should, and cuts review-preparation time.

THE UTILITY BRINGS

Historical facility-rating worksheets and final approvals.
Clearance or line-design reports, one-lines, equipment lists.
The internal rating methodology the checks must honor.
A facility-ratings or line-engineering SME, a few hours a week.

WE BRING

Evidence ingestion and cross-system asset reconciliation.
The utility-approved check set, configured together.
A review package for every historical case.
A held-out evaluation and an honest production-gap report.

No live SCADA. No OT access. No autonomous decisions. The pilot runs on records that already exist, which means it can start in weeks.

EVERY CAPACITY CLAIM SHOULD CARRY ITS PROOF

Bring one completed rating change. We will show you what it proves.

What is traceable, what conflicts, and what is still missing. On your own historical package, in one working session.
