Measured load reduction percentage calculator

Express the reference's before/after load comparison as a percentage reduction on the baseline load.

R=100×(Pbefore−Pafter)PbeforeR = \frac{100 \times \left(P_{\text{before}} - P_{\text{after}}\right)}{P_{\text{before}}}

Worked example

Given

  • PbeforeP_{\text{before}} = 82 kW
  • PafterP_{\text{after}} = 29 kW
R=100×(82−29)82≈64.634R = \frac{100 \times \left(82 - 29\right)}{82} \approx 64.634
