Sterility Test Equipment Load with sterility test equipment connected load of 1.75 kW: a worked example

This worked example runs the sterility test equipment load numbers for a tougher week than the baseline: sterility test equipment connected load of 1.75 kW instead of the typical 3.5 kW. Estimate energy cost and sample-normalized load for sterility test incubators, readers, and supporting QC equipment.

The inputs for this scenario

  • Sterility test equipment connected load: 1.75 kW (the input this scenario stresses; the baseline uses 3.5)
  • Sterility test equipment runtime: 336 hr (held at the documented default)
  • Blended laboratory electricity rate: 0.16 $ / kWh (held at the documented default)
  • Sterility samples or batches supported: 48 samples (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Sterility test equipment energy cost = connected load × equipment runtime × blended laboratory electricity rate.
  • Sterility test equipment energy cost works out to 94.08 $ energy at these inputs, and this is the headline figure for the scenario.
  • Sterility test equipment energy used works out to 588 kWh at these inputs.
  • Energy cost per sterility sample works out to 1.96 $ / sample at these inputs.
  • Hourly sterility equipment energy cost works out to 0.28 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where sterility test equipment connected load sits at 3.5 kW and the headline result is 188 $ energy, this scenario comes in 50% below the baseline at 94.08 $ energy.
  • Use it when allocating utility cost to QC release testing, sizing UPS or generator coverage, or comparing in-house versus outsourced sterility energy overhead. 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

  • Sterility test equipment energy cost: 94.08 $ energy (headline result)
  • Sterility test equipment energy used: 588 kWh
  • Energy cost per sterility sample: 1.96 $ / sample
  • Hourly sterility equipment energy cost: 0.28 $ / hr
