Energy Cost Estimator

Two lines that make the same product can differ by two orders of magnitude in the electrical column and not at all in the physics. The published loads only become comparable once they are divided by output and multiplied by your own tariffs. Enter what you pay and this returns energy cost per kilogram of finished product for any two of the thirteen models side by side.

All Thirteen Models on Your Tariffs

The electrical load and the gas consumption in the first two columns are the published parameter-sheet values. Output is converted to kilograms per hour on the basis the sheet uses, which is not the same basis for every model: four of the thirteen are rated in pieces per hour and depend on the piece weight you entered, two are rated per shift day and depend on your running hours per day, five are rated per 24 hours and are simply divided by 24, and two are already published per hour. Energy cost per kilogram is the sum of the two energy streams divided by that output, so it moves when your tariffs move and when your piece weight moves.

A dash in the last three columns means the output basis for that model needs a figure you have not entered yet, either a piece weight or a running hours per day, so the division has no honest answer.

What These Numbers Do and Do Not Include

Electricity and gas are not interchangeable

A gas-fired line and an all-electric line of the same output are not two versions of one machine. The gas line needs a supply, a pressure, a flue and a permit; the electric line needs a transformer and a cable. Swapping between them after the building is committed is a rebuild, not a change order, and the cost per kilogram calculated here is only the running cost, not the cost of getting either supply to the wall.

The gas figure needs no calorific conversion

The parameter sheet publishes gas consumption in cubic metres per hour, and your gas tariff is quoted per cubic metre, so the two multiply directly. No calorific constant is introduced anywhere in this calculation, which is deliberate: an assumed megajoule-per-cubic-metre figure would silently change every result on the page.

Cost per kilogram, not cost per hour

Cost per hour makes a small machine look cheap. The YT-06 draws 5.8 kW against the YT-XMT800’s 418 kW, which is a seventy-fold difference in the hourly bill, and it disappears the moment both are divided by what they actually produce. Energy per kilogram is the only basis on which a bench machine and a 55-metre line can be compared at all.

What is left out

Compressed air, water, cooling, standby losses, power factor penalties, and the energy used during warm-up and changeover are all excluded, because none of them is published on the parameter sheet and inventing a figure for them would corrupt the comparison rather than complete it. Treat the result as the floor of your energy cost, not the whole of it.
