A load study shouldn’t take six weeks and a consultant.
Traditional firms sell hours: site walks, spreadsheets, weeks of waiting. Wattif rebuilds your electrical system as a verified model, runs the NEC 220.87 math on your own measured demand, and a licensed engineer seals the package. Fixed price per report. Most come back in 3 days.
One question, answered two ways.
From your utility records
Your real 12-month peak, times 125%. Routinely recovers capacity the calculation cannot see.
From $500 · 3 days →From 30 days on the panel
The only measured path for feeder and sub-panel additions, or when no usable records exist.
From $3,300 · about 5 weeks →Three steps. 30 days. One answer.

Sensors go on the panel
A contractor mounts CT clamps on your mains and feeders, typically under an hour on site. No shutdown, no rewiring, no disruption to the facility.
- 02 · Day 1 to 30
30 days of evidence
We monitor exactly what your study needs: the mains, one feeder, or several panels across the site. Real kilowatt data at 1 to 15 minute resolution, matched to the question.

The determination, sealed
The recorded peak is taken to 125% under NEC 220.87 and set against the rating of the service or the feeder the load is going on. A licensed engineer reviews and seals it. You get the answer in plain language, with the numbers behind it.
How else would you get this answer?
There are three ways to get a permit-ready load study today. Two of them cost more and take longer.
Engineering consultant
Hourly billing, a site walk to redraw what your documents already show, and the study lands in the queue behind bigger jobs.
Do it in-house
Spreadsheet NEC 220 math from the panel schedule. Nobody has checked it, the AHJ will not take it unsealed, and the liability stays with you.
Wattif load study
Five published prices, sealed from $1,800, metering only where the question needs it. AHJ and utility revisions free until the submittal is accepted.
