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 engineer signs it under their own licence, 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 the codes adopted by the authority that approves the work.
The Engineer's Signature
A licensed 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
- 01FirstThe room you haveThe existing load from 12 months of your utility's interval data, against the service rating. Nothing is fitted to the panel.
- 02NextWhat frees capacityMeters on the main boards show the current at the peak that does no useful work, circuit by circuit, and the change that returns each part.
- 03ThenThe changes, specifiedEach change written for your electrician, with the amps it frees, simulated on your own demand before anything is touched.
- 04After the changesThe peak, measured againThe service read again with the changes made and the new load running, and the result signed by a licensed engineer under their own licence.
