District Energy & Thermal Network Equipment worked example

Controls Commissioning Load with commissioning connected load of 6 kW: a worked example in district energy & thermal network equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop commissioning connected load to 6 kW, then walk the calculation through step by step. Estimate energy and cost consumed while commissioning plant controls, metering, pump sequences, ETS controls, and network temperature reset logic.

The inputs for this scenario

  • Commissioning connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Controls commissioning runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Control points or stations commissioned: 1,000 points or stations (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Controls commissioning energy used = commissioning connected load × controls commissioning runtime.
  • Controls commissioning energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Controls commissioning energy cost works out to 5.76 $ at these inputs.
  • Energy cost per control point or station works out to 0.01 $ / piece at these inputs.
  • Hourly controls commissioning energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where commissioning connected 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 commissioning connected load, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes the full connected load runs for the entire commissioning runtime, which overstates energy if testing is intermittent or staged across subsystems.

  • Controls commissioning energy used: 48 kWh (headline result)
