Define the decision the study must support
An energy study may be intended to explain rising bills, reduce maximum demand, assess a proposed investment or create a longer-term improvement plan. The objective determines the measurement duration, equipment coverage and level of financial analysis.
Build a reliable baseline
- Collect utility bills and production or occupancy information for a representative period.
- Reconcile major loads with the single-line diagram and operating schedule.
- Identify seasonal, shift and process changes that affect comparison.
- Record assumptions and data gaps rather than hiding them.
Measure where it changes a decision
Temporary logging can help separate base load, process demand, motor duty, power factor and harmonic behaviour. Measurement points and duration should be selected around the question, not simply around available instruments.
Prioritise opportunities
A useful action plan distinguishes operational improvements, maintenance issues and capital projects. Each opportunity should state the evidence, assumptions, implementation dependencies and a method for verifying performance afterward.
