Every transformer's load at 2, 5 and 10 years, before EVs and solar arrive

A fast-growing municipal utility · DER growth planning

60%of overload failures flagged a year or more ahead

The problem

A fast-growing city utility plans upgrades from feeder-level forecasts and rules of thumb. Transformers on streets where EVs and heat pumps cluster fail from overload before any plan flags them, while some capacity projects get built years before the load shows up. Each rooftop solar or battery application takes an engineer hours to review.

What we ran

A municipal network of 60,000 customers and about 8,000 service transformers. Ten years of growth ran under low, expected and high scenarios for EVs, rooftop solar, heat pumps, batteries and new large loads, then compared against a rule-of-thumb plan.

What the agent did

It projects loading on every transformer and feeder at 2, 5 and 10 years using virtual-meter load shapes, flags each asset that crosses its limit and the year it does, ranks upgrades by year and risk, and pre-screens each solar or battery application against the projected loading. Planners approve the plan.

What it is worth

* Study simulated with partners on public data.

Run it on your network

The feeder model, a year of smart meter load and the interconnection queue. We return a 10-year loading map for one substation area.
