GSE Hydraulic Test Energy Load with hydraulic test stand connected load of 95 kW: a worked example

What does the result look like when hydraulic test stand connected load reaches 95 kW? The full calculation is worked below with real intermediate numbers. a GSE manufacturer or maintenance shop needs to estimate energy demand for hydraulic functional testing

The inputs for this scenario

  • Hydraulic test stand connected load: 95 kW (raised for this scenario; the documented default is 38)
  • Hydraulic test runtime: 7.5 hr (unchanged)
  • Electricity rate: 0.14 $ / kWh (unchanged)
  • GSE units hydraulic-tested: 12 units (unchanged)

Working through the calculation

  • Applying the documented formula (Hydraulic test energy used = connected load × hydraulic test runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 713 kWh for hydraulic test energy used, the number this scenario is built around.
  • At this operating point the engine returns 99.75 $ for hydraulic test energy cost.
  • At this operating point the engine returns 8.31 $ / GSE unit for energy cost per gse unit tested.
  • At this operating point the engine returns 13.3 $ / hr for hydraulic test energy cost per hour.

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 150% above the baseline at 713 kWh.
  • A figure at this level is achievable when hydraulic test stand connected load is genuinely sustained, not just peaked for a shift. It assumes the connected load runs continuously at the rated value; real test cycles include idle and low-pressure phases, so actual energy is often lower than nameplate load times runtime.

Results at a glance

  • Hydraulic test energy used: 713 kWh (headline result)
  • Hydraulic test energy cost: 99.75 $
  • Energy cost per GSE unit tested: 8.31 $ / GSE unit
  • Hydraulic test energy cost per hour: 13.3 $ / hr
