Same-Boundary Energy Verification
Verify energy only by recording a baseline, defining a configuration, then re-testing on the same machine, duty cycle and measurement boundary. A result from a different boundary is not a like-for-like comparison.

Record a baseline before changing the configuration
Identify the equipment, motion, stable work cycle and measurement start and end points. Record the baseline before treating a proposed configuration as a comparison candidate.
Keep a simple comparison sheet with meter readings, elapsed production time and completed output for both runs. Record interruptions or changes in material and cycle settings alongside the readings. Use average measured input power or metered energy over a representative cycle when estimating running cost; the motor nameplate is not a measurement of actual electricity use. You can then use the energy-savings calculator with annual operating hours, your electricity tariff and the proposed investment.
Re-test the same boundary
After configuration, repeat the measurement on the same equipment and work cycle. Keep the measurement boundary consistent and record exceptions so the comparison can be reviewed.
Review record
- Baseline record
- Configuration and revision
- Same equipment and duty cycle
- Same measurement boundary
- Re-test record and exceptions
Translate measured savings into running costs
Measure electricity use at the same output, then combine the result with annual operating hours and your electricity tariff to calculate the change in annual running costs.
FAQ
Frequently asked questions
Why must the boundary stay the same?
Changing the equipment, duty cycle or measurement start and end points changes what is being compared. A controlled comparison keeps those conditions aligned.
How can I estimate electricity savings for my machine?
Share your current power draw, motion and holding times, annual operating hours and electricity tariff. We can help define a measurement plan and estimate savings.
