Sample Lab Load with sample lab connected load of 2.75 kW: a worked example

This worked example runs the sample lab load numbers for a tougher week than the baseline: sample lab connected load of 2.75 kW instead of the typical 5.5 kW. Estimate energy and cost for sample lab equipment used to prepare, mix, heat, chill, homogenize, or test flavor and fragrance samples.

The inputs for this scenario

  • Sample lab connected load: 2.75 kW (the input this scenario stresses; the baseline uses 5.5)
  • Sample lab operating time: 7 hr (held at the documented default)
  • Blended electricity rate: 0.14 $ / kWh (held at the documented default)
  • Samples prepared or tested: 180 samples (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total sample lab load cost = sample lab connected load × sample lab operating time × blended electricity rate.
  • Sample Lab Load energy used works out to 19.25 kWh at these inputs, and this is the headline figure for the scenario.
  • Total sample lab load cost works out to 2.7 $ at these inputs.
  • Energy cost per lab sample works out to 0.01 $ / piece at these inputs.
  • Hourly sample lab load cost works out to 0.39 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where sample lab connected load sits at 5.5 kW and the headline result is 38.5 kWh, this scenario comes in 50% below the baseline at 19.25 kWh.
  • Use it when costing a creative submission, building a lab overhead rate, or comparing energy cost across benches, shifts, or analytical instruments. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Sample Lab Load energy used: 19.25 kWh (headline result)
