From Vending Energy Label to Electricity Budget: A Worked Example
An energy label can help you build an initial electricity allowance for refrigerated vending equipment, provided you keep the calculation and its assumptions visible. It is not a guaranteed bill for your site. Use the figure for the actual proposed model, apply a clearly identified electricity rate and explain what the result includes. Then plan how the estimate will be reviewed against suitable operating information later.
Begin with the correct consumption figure
The European Commission’s commercial refrigeration guidance identifies annual energy consumption in kWh among the information on the relevant label. Ask the supplier for the label and information sheet matching the quoted equipment. Do not copy a consumption figure from another cabinet in the same product family or use a photograph that cannot be connected to the offer.
Keep kWh separate from money. The energy figure describes consumption under the applicable assessment method; your cost calculation adds a tariff assumption. Ask the supplier about the operating conditions relevant to the proposed location. A site’s actual use may differ, so keep the first calculation labelled as an estimate rather than presenting it as a promise about future invoices.
Make the arithmetic easy to audit
Consider a purely hypothetical machine using 1,200 kWh annually and an assumed energy rate of €0.30 per kWh. Multiplying 1,200 by €0.30 gives €360 per year. Dividing by twelve gives an average allowance of €30 per month. These numbers are an illustration only: they are not specifications for the machine pictured, a current Irish tariff or a quotation from our business.
State whether the rate used includes or excludes taxes and other charges, using information supplied by the person responsible for the site’s electricity account. Do not silently add the whole building’s standing charge to one machine. Ask finance which costs belong in the decision and keep any separately allocated charges visible. The simple multiplication estimates the stated energy component, not every item on a utility bill.
Show how the result changes
Using the same hypothetical 1,200 kWh figure, an assumed rate of €0.25 produces €300 annually, while €0.35 produces €420. This range illustrates sensitivity to the rate; it is not a forecast of future electricity prices. Replace the assumptions with the site’s supported figures and retain the date and source so the calculation can be updated when circumstances change.
If comparing two machines, apply the same tariff basis and explain any difference in the job they are expected to do. A lower energy estimate is not automatically the best purchase if the equipment cannot meet the required product or capacity brief. Keep energy alongside purchase cost, servicing, stock handling and customer access in the wider comparison, with each assumption stated separately.
Plan a later review without guessing
Agree how actual consumption could be assessed safely and appropriately for the installed equipment. Ask the supplier or relevant competent person about a suitable method; do not improvise electrical connections or move a cabinet to reach a socket. Record the period and operating conditions of any measurement so it is not compared uncritically with an annual label figure.
When reviewing the budget, distinguish a changed tariff from changed consumption. Also note material changes in location, operation or equipment configuration. A higher cost does not by itself establish that the machine has become less efficient. Keeping the underlying figures makes the conversation more useful and helps identify whether the estimate, operating conditions or equipment needs further attention.
Our vending cost guide provides wider buying context. Use a documented energy estimate as one part of that budget, with explicit assumptions and a planned review.
