GSE Hydraulic Test Energy Load with hydraulic test stand connected load of 19 kW: a worked example

This worked example runs the gse hydraulic test energy load numbers for a tougher week than the baseline: hydraulic test stand connected load of 19 kW instead of the typical 38 kW. Estimate energy used and cost for hydraulic test stands used on belt loaders, cargo loaders, deicers, stairs, and other powered GSE.

The inputs for this scenario

  • Hydraulic test stand connected load: 19 kW (the input this scenario stresses; the baseline uses 38)
  • Hydraulic test runtime: 7.5 hr (held at the documented default)
  • Electricity rate: 0.14 $ / kWh (held at the documented default)
  • GSE units hydraulic-tested: 12 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Hydraulic test energy used = connected load × hydraulic test runtime.
  • Hydraulic test energy used works out to 143 kWh at these inputs, and this is the headline figure for the scenario.
  • Hydraulic test energy cost works out to 19.95 $ at these inputs.
  • Energy cost per GSE unit tested works out to 1.66 $ / GSE unit at these inputs.
  • Hydraulic test energy cost per hour works out to 2.66 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where hydraulic test stand connected load sits at 38 kW and the headline result is 285 kWh, this scenario comes in 50% below the baseline at 143 kWh.
  • Use it when costing a test campaign, sizing electrical supply to a test cell, or evaluating whether a more efficient pump pack pays back. 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

  • Hydraulic test energy used: 143 kWh (headline result)
  • Hydraulic test energy cost: 19.95 $
  • Energy cost per GSE unit tested: 1.66 $ / GSE unit
  • Hydraulic test energy cost per hour: 2.66 $ / hr

Run it with your numbers
