Energy Spend Analyst
Finds the wrong tariff, the peak that sets your bill, and what runs all night
2 bills run well above what your tariff produces: about $1,043 to query.
12 bills, $91.4K for 527,300 kWh; average $0.173 a kWh.
Demand charges are $27K (29.6% of spend); the average load factor is 37.5%, so peaks are high for the energy used.
Bills sit about 6.1% above the recomputed charge (fixed charges and taxes). Aug 25, Mar 26 stand out at 5 points or more above that.
Time-of-use bands and interval meter data are not in the data; the gap is fixed charges, taxes and anything unexplained.

Bills to query
| Month | Billed | Recomputed | Gap | Gap % |
|---|---|---|---|---|
| Aug 25 | $10.2K | $8,975 | $1,185 | 13.2% |
| Mar 26 | $7,690 | $6,863 | $827 | 12.1% |
What to do this week
- Ask the supplier to explain Aug 25, Mar 26: the gap is above your usual fixed charges and taxes.
- Cut the peak in Aug 25: every 10% off the peak is worth about $2,703 a year.
- Check the demand reading for Aug 25: the highest peak sets a large part of the charge.
Do
- Compare the flagged bills with the meter's interval readings before you write to the supplier.
Don't
- Don't treat the whole gap as an overcharge: some of it is fixed charges and taxes.
How to improve
- Add time-of-use rates so the next report can price each interval.
- Add the fixed charges and taxes on your tariff so the next report can explain the whole gap.

Overview
A commercial energy bill is not price times quantity. It is supply, distribution and capacity charges, a reactive power penalty, a peak demand charge set by one fifteen-minute interval in the month, standing charges, levies and taxes — each with its own basis. Almost nobody checks any of it, because checking means understanding a tariff document written by a utility for other utilities.
So three things persist for years. The site is on the wrong tariff for how it actually uses energy — a pure paperwork saving needing no behaviour change. The peak demand charge is set by a handful of minutes a month, often equipment starting simultaneously, and moving one start by ten minutes changes the bill permanently. And baseload: what a site draws when it is closed and nothing should be running, the clearest waste signal available, appearing in no bill summary.
The quiet one is estimated readings. A site billed on estimates accumulates a correction that arrives as a single large charge, and the estimate is rarely in your favour.
This agent reads consumption against the tariff and reports what each finding costs a year. It switches no supplier and controls no equipment.
Benefits
Savings with no behaviour change
Most of it is tariff and timing, not consumption.
The peak explained
Which minute set the charge, and what was running.
Bills that get checked
Which alone changes what suppliers send you.
What it does
Finds the peak that sets the bill
One fifteen-minute interval a month decides a charge you pay all year. Usually equipment starting together.
Measures baseload when closed
What the site draws when nothing should be running. The clearest waste signal there is, and it appears in no bill.
Tests the tariff against actual use
A paperwork saving needing no behaviour change, and it survives for years because nobody checks.
Catches power factor penalties
A charge for something most sites do not know they are being billed for.
Flags estimated billing
Estimates accumulate into one large correction, and they are rarely in your favour.
Switches nothing
It contacts no supplier, signs no contract, and has no route to any building control system.
What this changes
What this changes about your week
- It takes over
- Checking an energy bill against the tariff and the meter data behind it.
- Done today by
- Nobody, because the tariff is written by a utility for other utilities.
- How often
- Never. It is paid on the assumption it is right.
- Typical manual effort
- Peak charges are set by single fifteen-minute intervals buried in interval data.
Why Energy & Utilities in particular. Much of a commercial bill is not consumption at all — it is tariff fit, a capacity charge set by one interval a month, a power factor penalty nobody knows they pay, and baseload running every night.
Runs unattended
Started by you or by an event, and it finishes on its own. Nothing waits for someone to be at a desk.
The same standard every time
The two-hundredth item is held to the bar the first one was. Consistency is the part people cannot sustain.
It cannot act on its own
Energy Spend Analyst has no path to sending, spending or committing. That limit is why its output is safe to act on.
How it runs
This agent runs server-side through the PROMIVO runtime. Each run is logged step by step and every tool call is permission-checked before it executes.

FAQ
Does it switch supplier or sign contracts?
No. It contacts no supplier and signs nothing. It reports what your current arrangement costs and where it does not fit your usage.
Does it control equipment?
No. It has no route to any building management or control system. It reports when demand peaks and what appears to coincide with it.
Do we need interval meter data?
For peak and baseload findings, yes — those live in the intervals. Tariff fit, estimated billing and penalty charges are visible from bills alone, and it says which findings the data supports.
