Security Audit Workload with audit-rig connected electrical load of 6 kW: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop audit-rig connected electrical load to 6 kW, then walk the calculation through step by step. Estimate security audit workload for payment terminal and retail hardware using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Audit-rig connected electrical load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Audit test runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Terminals audited during the run: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total security audit workload energy cost = security audit workload connected load × security audit workload runtime × blended electricity rate.
  • Security audit workload energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total security audit workload energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly security audit workload energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where audit-rig connected electrical load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to audit-rig connected electrical load, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts only the rig's connected electrical load; HVAC to cool the lab, standby draw between runs, and labor are not included.

Results at a glance

  • Security audit workload energy used: 48 kWh (headline result)
  • Total security audit workload energy cost: 5.76 $
  • Energy cost per kWh: 0.01 $ / piece
  • Hourly security audit workload energy cost: 0.72 $ / hr
