Labeling Line Energy Cost with bottling and labeling line load of 10 kW: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop bottling and labeling line load to 10 kW, then walk the calculation through step by step. Estimate the electricity cost of running the labeling, coding, and serialization line, so packaging and cost teams can fold it into cost per bottle.

The inputs for this scenario

  • Bottling and labeling line load: 10 kW (the input this scenario stresses; the baseline uses 20)
  • Labeling and serialization run time: 7 hr (held at the documented default)
  • Electricity rate: 0.14 $ / kWh (held at the documented default)
  • Bottles coded and labeled: 60,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Labeling line energy cost = bottling and labeling line load × labeling and serialization run time × electricity rate.
  • Labeling line energy cost works out to 9.8 $ at these inputs, and this is the headline figure for the scenario.
  • Energy used works out to 70 kWh at these inputs.
  • Energy cost per unit works out to 0 $ / unit at these inputs.
  • Energy cost per hour works out to 1.4 $ / hr at these inputs.

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 50% below the baseline at 9.8 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to bottling and labeling line load, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Labelers draw in short bursts as bottles index through, so steady-load math slightly overstates energy on intermittent runs.
