Earthflow Underground · A virtual sensor on every buried power cable
Shine a light on the grid
beneath our feet.
America runs on 1.1 million miles of buried power cable, and no one can see it. Earthflow Underground shows utilities how healthy every cable is, when it's likely to fail, and how much it can really carry, every month.
The problem
The grid is moving underground, out of sight.
Utilities replace cable by age or after it fails, and rate it with one number for a whole territory. Meanwhile data centers, EV charging and electrification land on the same cables.
We don't know
Cable condition
Which segment fails next, and when. Age alone can't say: a 15-year-old cable in wet clay can be in worse shape than a 40-year-old one in dry sand.
We don't know
Cable capacity
What each cable can really carry in the ground it actually sits in. A static nameplate rating ignores soil, moisture, burial depth and the neighbours sharing the duct bank.
What you get
Every cable segment, scored every month.
From records you already hold. No new sensors, no outages, no rip-and-replace. Delivered as data into the tools you already use.
Health index
A condition score for every segment, with a confidence band and the inputs behind it.
→ Fewer failures, lower O&M
Probability of failure
As a likely range, ranked across the whole territory.
→ A risk list you can act on
Remaining-life band
How many years are left, and the dominant driver wearing the cable out.
→ Defer replacing healthy cable
In-situ rating & headroom
An environmentally adjusted rating, normal and emergency, and the year headroom closes. Up to 30% more than a static rating.
→ Connect new load faster
Dominant driver
Thermal, electrical, chemical, hydrologic or environmental stress: the cause, not just the symptom.
→ Fix the cause, test where it counts
Recommended action
Replace, test, defer or monitor, with the reason and provenance on every field.
→ Capex that stands up in a rate case
How it works
Start with four extracts.
We do the rest.
Send what you already hold
Read-only, one way. Messy data is fine.
Our physics engine models every segment
Electrical, thermal, chemical, hydrologic and environmental stress, on the real ground each cable sits in. Not a black-box model trained on someone else's network.
Get a monthly data feed
CSV, Parquet, GeoJSON or API, plus a PDF/HTML report. Roll up to feeder, substation or territory, or drill to one segment.
Proof
Validated by EPRI.
Benchmarked blind.
Technically validated by the head of EPRI's MV Distribution Research Lab, and listed in EPRI VantagePoint.
Every score carries its inputs, its confidence band and the physics behind it, so an engineer can check the work and a regulator can follow it.
Not an LLM. Not trained on other utilities' data. Not a SaaS lock-in.
Why now
America's underground grid has new owners.
None of them know what's in the ground.
Data centers
~90 GW
of planned on-site power, on private campus cable networks.
Private capital
$11.5B
Blackstone–TXNM. Investors are buying wires they have never seen.
Military
~500 bases
moving to run their own power, on their own buried networks.
Competition
~50%
of new UK connections now won by independents, not the incumbent utility.
Every new owner inherits buried cable blind. We make it visible, scored and ready.
The Earthflow platform
One physics core. Five editions.
Earthflow Underground sits on the same physics engine that screens sites, runs solar twins and prices peril. One core, trained on the ground itself.
Utilities
