Are You Comparing Electricity Costs Fairly?
Normalize electricity consumption and cost against a physical or operational basis such as floor area, occupied units or production output. This helps separate genuine efficiency changes from changes in scale.
What electricity cost normalization does
Normalization converts raw electricity consumption or spending into a measure that accounts for scale. A larger building can use more electricity while still performing better per square metre, for example.
Choose a basis that reflects the operation
Floor area can be useful for comparable buildings. Occupied units may be more meaningful for residential or hospitality properties, while production-based normalization can be more informative for manufacturing.
Why raw kWh can mislead
If a facility expands, increases output or changes operating hours, its electricity consumption may rise even though its energy performance per unit of service improves.
Normalization is not a substitute for diagnosis
A lower normalized intensity does not automatically mean the underlying equipment is more efficient. Weather, operating schedules, occupancy and production mix can all affect the result.
FAQs
Can I normalize by square foot?
Yes. Select floor area and enter the area in the same unit for both periods.
Can I compare different buildings?
Yes, provided the buildings have a comparable normalization basis and similar enough operating characteristics for the comparison to be meaningful.
Can electricity cost be normalized separately from kWh?
Yes. Cost intensity and energy intensity can tell different stories when electricity prices change.
Does normalization remove weather effects?
No. Weather normalization requires additional variables or a separate model.
