Schedule-correction energy reduction calculator

For stated constant on-state power and negligible off-state input, a schedule correction avoids power times removed energized hours; confirm service requirements before implementation.

Sschedule=Pon×(hold−hnew)S_{\text{schedule}} = P_{\text{on}} \times \left(h_{\text{old}} - h_{\text{new}}\right)

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Worked example

Given

  • PonP_{\text{on}} = 17 kW
  • holdh_{\text{old}} = 5,200 h
  • hnewh_{\text{new}} = 3,100 h
Sschedule=17×(5200−3100)=35,700S_{\text{schedule}} = 17 \times \left(5200 - 3100\right) = 35{,}700
