Capacity Recovery
Whether to sign the upgrade quote, or recover the capacity you already have first.
Current doing no useful work found circuit by circuit, the changes designed and simulated, the control run on site, and the panel measured again.

What You Can Decide With It
| 1 | RTU-1 and RTU-2 start together at 07:00Stagger starts by 10 minutes | 18.6 kVA |
| 2 | Dock exhaust fans at full speed all dayDrive speed matched to occupancy | 9.2 kVA |
| 3 | Compressor C-1 held above tool pressureSetpoint to the tools' requirement | 4.0 kVA |
| 4 | Power factor 0.84 at the serviceCorrection to 0.96 | 32.2 kVA |
| Recoverable at the measured peak | 64.0 kVA |
Key circuits recorded for 6 weeks, Jun to Jul 2026, in the peak season, with 12 months of utility demand. Simulated on the measured demand before anything changes.
What Can Be Recovered
The design: each source of current doing no useful work, the circuit it sits on, what it occupies at the peak and the change that returns it, simulated on your own measured demand. Changes are specified by what they must achieve, never by brand.
| Change | kW designed | kW measured |
|---|---|---|
| RTU starts staggered | 15.6 | 13.1 |
| Dock exhaust on a drive | 7.7 | 6.5 |
| Compressor to tool pressure | 3.4 | 2.9 |
| Power factor to 0.96 | 0 | 0 |
| Total | 26.7 | 22.5 |
Same instruments on the same channels, weather-normalised against the baseline window. Designed 64.0 kVA, achieved 59.6 kVA.
The Panel, Measured Again
The same instruments in the same positions once the changes are in place and the control is running. It states the capacity returned at the peak, then each change against the kW the design said it would take off.
The service supports the addition.
The Answer First
Existing demand, the load you want to add, the headroom that remains and the verdict, on one page. A licensed Professional Engineer signs it, and the method is named beside the result.
I hereby certify that this load study, the attached single-line diagram, panel schedules, and calculations were prepared under my direct supervision, and that to the best of my knowledge they comply with NEC 220 and the applicable codes of the authority having jurisdiction.
The Engineer's Signature
A licensed Professional Engineer reviews the whole document and signs it under their own licence. This is the page that gives the calculation its standing.
How It Is Produced
- 01FirstDeterminationA high-level estimate of the capacity your service has. Nothing is fitted to the panel.
- 02NextInvestigationThe Load Study: the detailed analysis, and the kW that can be unlocked.
- 034 to 8 weeksIntervention: DesignKey circuits recorded in the peak season. Which loads change, what sheds and how many kW come off, simulated on your own data.
- 04OngoingIntervention: Managed CapacityA licensed electrician fits the controller and any physical change. Wattif runs the control, and the panel measured again is signed by a licensed Professional Engineer.
