Enmon through the eyes of the CFO

The most expensive signature of the month
is made blind.

One day a month the energy invoice lands. A huge sum, up year on year, and the only information on the table is an “Approve” button. Play that day from 8:52 to 16:30, twice. Once the way you know it. Then with Enmon.

The day the energy invoice arrives

Eight moments of one day. On the left, the way most CFOs know it. On the right, the same day with data.

8:52

A morning look at cash flow

Before
?

How much have we spent on energy this month? The answer arrives with the invoices, one by one, a month late.

The second biggest cost after payroll is a black box for cash flow until the due date.

After, with Enmon

You watch the drawdown continuously from measured data, the month-end invoice is a confirmation, not a surprise.

▲ +18% vs. the same month last year

The biggest regular payment after payroll. Why did it grow? Consumption? Prices? An error? The system offers a single action: Approve. Try it.

Approved, unchecked
After, with Enmon

Consumption matches measured data (+4%, higher production)
Unit prices match the contract (+11%, new price list since January)
Reserved capacity not exceeded
Reactive power: €500, item to investigate

The same invoice, with context. That +18% has a name and a cause before you touch the button. And one item blinks red.

9:26

What do those lines actually mean?

Before
Invoice linespage 3/7
Electricity commodity HT/LT1 128 400
Distribution + reserved capacity492 180
Power-factor penalty (reactive power)12 400
System services, renewables levy, tax…214 250

Reactive power? Power factor? I call the energy manager, on holiday. The distribution contract? Somewhere with legal, last version 2021. The check ends before it began.

After, with Enmon

Distribution and capacityfor guaranteed supply, no breach this year✓ per contract
Reactive power €500a power-factor penalty, compensation can cut it to zero✗ needless
Regulated itemsset by the state, we check the rates✓ correct

Every line in plain language, the contract attached at the metering point, and a clear verdict: this item is needless and can be removed for good.

10:05

The signature

Before

The clock is ticking, you don’t want to upset the supplier, and nobody in the building can say whether the invoice is right. So you pay. All of it. Again.

Paid, €74,000

The reactive power burns through next month too. And the next. €500 a month is €6,000 a year, for nothing.

After, with Enmon

The invoice checks out except one item. You pay with peace of mind, and claim the reactive power with a power-factor chart attached. A compensation request goes out too, so the item disappears for good.

Paid, €73,000Claimed, €500

The bank calls: substantiate the green-loan numbers

Before
Documentation for the bankdata origin
Energy_2025_v7_FINAL.xlsxauthor: the energy manager · methodology: in his headunverifiable
Change history“a controlling colleague edited it too”none

Auditors and the bank want the origin of the numbers. “From the energy manager’s Excel” no longer passes, and better loan terms leave with it.

After, with Enmon
Documentation for the bankaudit trail
Consumption and emissionsfrom meters, 15-min granularity, complete series✓ substantiated
Every valuewho · when · from where · by what methodology✓ traceable
Year-on-year intensity reductionthe basis for the green-loan rate✓ measured

The export goes to the bank the same day. A data trail instead of a spreadsheet, and the rate negotiation stands on numbers, not trust.

13:40

Accounting rebills the tenants

Before
AccountantI split it by the m² key as always, it comes to €8,700 for the ground-floor tenant.
TenantThat’s a third more than last year, we dispute it. Nobody can substantiate your calculations.
YouTwo spreadsheets, two numbers. I don’t know where the truth is, and the dispute hangs on me.

Three versions of the truth, zero meters. The dispute ends in a goodwill discount, and starts over next month.

After, with Enmon
Ground-floor tenant€7,900
1st-floor tenant€5,700
2nd-floor tenant€3,700
Common areas€2,600

Rebilling from submeters, not a key, every invoice with a consumption chart attached. There is one truth and it is measured. The dispute never happens.

15:10

An investment on the table: power-factor compensation

Before

Another request from operations: “Let’s buy a compensation cabinet, it will save money.” How much? “Definitely a lot.” Without numbers it is just another paper in the capital queue.

Deferred, substantiate the benefit

A deferred decision costs money too: the morning invoice’s reactive power keeps running, €500 every month.

After, with Enmon
Investment card, power-factor compensationmodel numbers
Investment€3,600
Substantiated loss (measured power factor)€6,000/yr
Payback≈ 7 months

The morning’s red item returns in the afternoon as an investment with measured payback. This approves itself.

Approved, 7-month payback
16:30

The board wants a cost outlook

Before
?

“What will energy cost us next quarter?” The budget is guessed from last year plus a buffer. And the buffer decides what does not get invested elsewhere.

The rooftop PV payback? “We believe it pays back.” Belief is not a financial category.

After, with Enmon
Energy costs, plan vs. actual + quarterly outlook
plan (dashed) · actual · outlook

An outlook from measured data and contract prices, plan vs. actual by cost centre, and PV payback substantiated by generation, not belief. The board gets numbers, not a buffer.

Beyond invoice day

Three views the CFO keeps year-round

The model day is a slice. This is the data that turns energy into a managed cost all year, before and after, like everything on this site.

Budget vs. actual, by cost centremodel numbers

Before
P&L, the cost linemonth
Energy (everything, everywhere, in one)€74,000
Deviation from plan+9 %
Explanationan e-mail from operations“it was cold”

One line in the P&L. The deviation gets explained in words, and next year’s budget is last year plus a buffer.

After, with Enmon
Production1 141 t.−5% vs. plan
Warehouse and cooling462 t.+10% vs. plan
Administration198 t.−4% vs. plan
Total1 801 t.−2% vs. plan

Every cost centre has its plan and actual. The warehouse deviation has a cause in the data (a dehumidifier fault, being fixed), not in the weather. And next year’s budget is built from measured history.

Active energy management typically delivers 4–15% cost savings with no technology investment, from operational optimisation, uncovered faults and invoice errors. Payback within 2 years with active use.

Reserved capacity, insurance you pay for

Before
Contracted capacitymodel metering point
Reserved capacity800 kW
This year’s actual maximum612 kW
Last Decemberan appliance overlap nobody sawbreach penalty

Two bad options at once: you pay for capacity you do not use, and every so often you exceed it anyway, because nobody watches the quarter-hour maxima.

After, with Enmon
Managed capacityquarter-hour maxima live
Alarm before the maximum is reached✓ notification in time
Overlaps of large appliances✓ managed by shifting
Capacity contracted from data✓ no padding

Maxima are watched continuously and capacity is contracted to measured reality, you pay for the certainty you actually draw.

This is not a model example: since deploying Enmon, one logistics operator has paid zero reserved-capacity breach penalties, across 18 branches in 3 countries. The full story is in our case studies.

Investments that are measured, not promised

Before

The business case gets computed before approval, and then nobody ever opens it again. Is the rooftop PV generating? “Probably.” Are the new boilers saving? “We believe so.”

Locked-up capital with no feedback: you do not know which investments to repeat and which never again.

?
After, with Enmon
Investments under watchmeasured against baseline
PV, generation vs. planmonth by month, deviation immediately✓ measured
Power-factor compensationreactive power on the invoice → €0✓ substantiated
LED, boilers, controlssavings against the pre-investment baseline✓ reported

Every investment has a baseline before and a measured impact after. Payback is a number in a report, not a sentence in a deck, and the next CAPEX is ranked by data.

A real benchmark: one client generates roughly 5 GWh a year from PV, over 30% of its own consumption, and tracks generation and payback in data. For every investment Enmon measures the impact against baseline, so “is it paying back?” stops being a question of faith.
What the CFO gets

Control over the second biggest cost

For most operations energy is the biggest regular payment after payroll, and the only one approved without documentation. Enmon returns it to financial control.

Invoices approved with documentation

Every invoice passes an automatic check against metering and the contract before it reaches you. You sign with a verdict, not with trust.

Budget tracking and forecasts

Plan vs. actual by cost centre, an outlook from measured data and contract prices. The energy budget stops being a guess with a buffer.

Investments with substantiated payback

PV, compensation, new boilers, every investment has a measured impact against baseline. And the audit and the bank get a data trail, not “the energy manager’s Excel”.

For financial decisions

Verify the numbers yourself

The calculator speaks CFO: an investment ceiling

We do not ask the price of the solution, we compute the annual savings in two scenarios and the investment ceiling for payback within the years you choose. We built the CFO argument in industry too: the APPROVED stamp there landed on a 2.1-year payback.

Sign your next invoice with documentation

It starts with a screening of metering points and contracts. The first month means the first invoice with a traffic light, and the first item you do not pay needlessly.
