Labeling Line Energy Cost with bottling and labeling line load of 50 kW: a worked example

Push bottling and labeling line load up to 50 kW and the picture changes. This example computes every intermediate figure at that operating point. A packaging or cost team needs the energy cost of running the labeling, coding, and serialization line for a run and the cost per labeled unit.

The inputs for this scenario

  • Bottling and labeling line load: 50 kW (raised for this scenario; the documented default is 20)
  • Labeling and serialization run time: 7 hr (unchanged)
  • Electricity rate: 0.14 $ / kWh (unchanged)
  • Bottles coded and labeled: 60,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Labeling line energy cost = bottling and labeling line load × labeling and serialization run time × electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 49 $ for labeling line energy cost, the number this scenario is built around.
  • At this operating point the engine returns 350 kWh for energy used.
  • At this operating point the engine returns 0 $ / unit for energy cost per unit.
  • At this operating point the engine returns 7 $ / hr for energy cost per hour.

How this compares with the baseline

  • Against the tool's baseline example, where bottling and labeling line load sits at 20 kW and the headline result is 19.6 $, this scenario comes in 150% above the baseline at 49 $.
  • It computes the electricity cost of a labeling and serialization run and breaks it into kWh, cost per hour, and cost per unit. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Labeling line energy cost: 49 $ (headline result)
  • Energy used: 350 kWh
  • Energy cost per unit: 0 $ / unit
  • Energy cost per hour: 7 $ / hr
