Energy change with different operating schedules calculator

A lower operating load can still increase energy when the schedule expands enough.

ΔE=Pbefore×Hbefore−Pafter×Hafter\Delta E = P_{\text{before}} \times H_{\text{before}} - P_{\text{after}} \times H_{\text{after}}

Worked example

Given

  • PbeforeP_{\text{before}} = 24 kW
  • HbeforeH_{\text{before}} = 60 h
  • PafterP_{\text{after}} = 16 kW
  • HafterH_{\text{after}} = 84 h
ΔE=24×60−16×84=96\Delta E = 24 \times 60 - 16 \times 84 = 96
