Data Center Electrical Capacity Calculator

Estimate facility electrical input capacity from IT load, target PUE, and an explicit reserve fraction.

Inputs

Planning inputs

Range: 1–1,000,000 kW

Enter planned IT equipment demand in kW. Do not include cooling or other facility loads here; PUE adds those below.

Range: 1–5 ratio

Enter the planning PUE ratio for the facility scenario. Use measured or documented project data when available.

Range: 0–80 %

Enter an explicit reserve allowance as a percentage of estimated facility input. This is a planning assumption, not a reliability or code requirement.

Result

Capacity including reserve (kW)
900.00
Estimated facility input (kW)
