Washer Energy Cost at 110% energy cost scope included: a worked example

What does the result look like when energy cost scope included reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when comparing wash temperature settings, heated tanks, drying ovens, pumps, and spray washer operating cost.

The inputs for this scenario

  • Washer energy operating hours: 160 machine hr (unchanged)
  • Energy cost per machine hour: 18 $ / machine hr (unchanged)
  • Energy cost scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed heat-up and demand cost: 380 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable washer energy cost = washer energy operating hours × energy cost per machine hour × energy cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,548 $ for total washer energy cost, the number this scenario is built around.
  • At this operating point the engine returns 22.18 $ / machine hr for energy cost per machine hour.
  • At this operating point the engine returns 3,168 $ for variable washer energy cost.
  • At this operating point the engine returns 380 $ for fixed heat-up and demand cost.

How this compares with the baseline

  • Against the tool's baseline example, where energy cost scope included sits at 100% and the headline result is 3,260 $, this scenario comes in 8.83% above the baseline at 3,548 $.
  • A figure at this level is achievable when energy cost scope included is genuinely sustained, not just peaked for a shift. The per-machine-hour rate bundles heating and pumping at one average load; a washer that spends more time idling at temperature than actively spraying will have a different effective rate than peak draw suggests.

Results at a glance

  • Total washer energy cost: 3,548 $ (headline result)
  • Energy cost per machine hour: 22.18 $ / machine hr
  • Variable washer energy cost: 3,168 $
  • Fixed heat-up and demand cost: 380 $
