Constant power and price; excludes fixed charges. Use PUE 1 if measuring the whole facility.
A 250 W server running 24 hours for 30 days uses 180 kWh at PUE 1. At 0.20 per kWh, the variable cost is 36 currency units, excluding fixed charges.
Constant power and price; excludes fixed charges. Use PUE 1 if measuring the whole facility.
Fields contain editable examples.
kWh = W/1000 × h/day × days × PUE; cost = kWh × priceConstant power and price; excludes fixed charges. Use PUE 1 if measuring the whole facility.
All amounts use the same currency of your choice. These are estimates, not measurements or offers.
Use measured average power, daily hours and days. A power supply’s maximum rating is not continuous consumption. Enter your contract’s unit price; the example is not a current tariff.
If you measure only IT equipment, PUE estimates total facility energy. PUE 1.5 raises this example to 270 kWh. Do not apply it again if cooling and other facility loads are already measured.
Total facility energy divided by IT-equipment energy over the same period; a multiplier in this model.
Only what is included in your unit price. Add other bill components separately.
Calculate each period with its own hours and price, then add costs without double-counting hours.
