Wasted energy
Connect energy use to its cause.
Compare power with the process duty the equipment delivers. Use the finding to focus an operating change or maintenance intervention.
The five usual culprits
| Pattern | Typically worth |
|---|---|
| Running when nobody is there | 8–15% |
| Too many machines, all part loaded | 5–12% |
| Efficiency lost to wear and fouling | 10–20% |
| Heating and cooling the same air | 3–8% |
| Everything starting at once | 15–25% of the peak charge |
§ 01
Why energy projects usually stall.
Most energy work produces a report. The report lists opportunities, somebody circulates it, everybody agrees, and then the people who would have to change something are busy keeping the plant running.
The gap is not analysis. It is that a finding in a report is not a job. Nobody is assigned to it, nothing raises it again next month, and there is no record of whether it was ever done.
So findings here end where work is raised. A saving worth having becomes a proposed job on a named machine, and if it is rejected the reason is kept.
“An opportunity nobody was assigned to is a paragraph, not a saving.”
Why savings evaporate
§ 02
What it gives you.
The percentages above are typical ranges seen across industry, not a promise about your plant.1
- 01What it should have used
Expected consumption adjusted for weather, occupancy, and how much you produced, so a cold week does not look like a fault and a quiet week does not look like a saving.
- 02What is driving your peak
The equipment that made this month’s peak charge, and what would happen to the bill if those starts were spread out.
- 03Which machines to run, and when
Suggested staging, setpoints, and schedules, each with the saving worked out, so the decision can be argued about in money.
- 04Proof the saving was real
Savings measured against the baseline afterwards, following the standard method, with a stated confidence rather than a claim.
- 05Your actual tariff
Consumption mapped onto what you really pay, including the hours you pay more, so shifting load can be valued properly.
- 06What it means for carbon
Energy converted to emissions using the factors for your grid, tracked against whatever target you have committed to.
Start with twelve months of bills and readings.
A year of meter data and a year of invoices is enough to show where the waste sits, what each pattern is worth on your tariff, and which of it can be fixed by changing how equipment is run rather than by buying anything.
- 1Ranges are typical industry figures for illustration, not measured customer results and not a projection for your site. What you can actually recover depends on your equipment, your tariff, and how the plant is run today. We build the model on your own data during an evaluation.
