Dairy & Frozen Food Manufacturing worked example

Refrigeration Energy Cost at 92% share of load assigned to this product or line: a worked example in dairy & frozen food manufacturing

What does the result look like when share of load assigned to this product or line reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when refrigeration energy cost in dairy and frozen food manufacturing is being put through a dairy and frozen food manufacturing weighted-cost review.

The inputs for this scenario

  • Refrigeration energy use for the period: 100 kWh or ton-hr (unchanged)
  • Electricity or refrigeration cost rate: 45 $ / kWh (unchanged)
  • Share of load assigned to this product or line: 92 % (raised for this scenario; the documented default is 80)
  • Fixed demand charge or utility adder: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Allocated refrigeration energy cost = refrigeration energy use or load × cost rate × assigned share) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total refrigeration energy cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for refrigeration cost per energy unit.
  • At this operating point the engine returns 4,140 $ for allocated refrigeration energy cost.
  • At this operating point the engine returns 250 $ for fixed demand or utility adder.

How this compares with the baseline

  • Against the tool's baseline example, where share of load assigned to this product or line sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when share of load assigned to this product or line is genuinely sustained, not just peaked for a shift. It assumes a flat cost rate and a fixed allocation share, so it will misstate cost under time-of-use tariffs or when load share shifts with ambient temperature and product mix.

Results at a glance

  • Total refrigeration energy cost: 4,390 $ (headline result)
  • Refrigeration cost per energy unit: 43.9 $ / piece
  • Allocated refrigeration energy cost: 4,140 $
  • Fixed demand or utility adder: 250 $
