Electricity is the biggest running cost of any data center. This calculator uses the AI Build Configurator formulas: IT load × utilisation plus cooling overhead (PUE), priced at the local rate with any large-load minimum-take floor. A 50 MW site at 88% utilisation and PUE 1.13 uses 442,380 MWh a year, about US$31.4M in Texas.

Calculate Your Data Center Power Cost

Data center power cost calculator

Formula: (IT MW × 8,760 h × utilisation + IT MW × (PUE − 1) × 8,760 h) × rate. Large-load minimum-take floors are applied above each state's threshold. Rates are the configurator's modelled industrial rates (Q4 2026); enter your own rate to override.

Server Power Usage: Watts, kWh and Cost per Server

A data center's power bill starts at the server. Annual energy is simply the server's average draw in kilowatts × 8,760 hours, then multiplied by the facility's PUE (power usage effectiveness) to cover cooling and electrical losses. Typical figures at full load:

1U CPU server
~0.5 kW · 4,380 kWh a year · about US$350 a year at US$0.08/kWh
Dual-socket storage / database server
~0.8 kW · 7,000 kWh a year · about US$560 a year
8-GPU AI training server
~10.2 kW · about 89,000 kWh a year · about US$7,100 a year
Liquid-cooled AI rack (GB200-class)
~120 kW · about 1.05 GWh a year · about US$84,000 a year

Those are IT-only numbers. At a PUE of 1.3, the meter reads 30% higher, so the 8-GPU server becomes about 116,000 kWh a year at the facility. Real servers average below their nameplate rating, while AI training clusters run close to it around the clock.

To turn server counts into a full facility bill, enter your IT load in the calculator above, or model the whole site, including cooling, construction and payback, in the AI Build Configurator.

Data Center Power Rates by State

Lowest US rates: per kWh, Louisiana and New Mexico Lowest provincial rates: per kWh, Manitoba Hydro

The cheapest modelled industrial rates in the configurator:

Louisiana
US$0.065/kWh · Entergy Louisiana / Cleco / SWEPCO
New Mexico
US$0.065/kWh · PNM / El Paso Electric / SPS
Oklahoma
US$0.068/kWh · OG&E / PSO
Texas
US$0.071/kWh · ERCOT retail market (Oncor / CenterPoint / AEP Texas TDUs)
South Carolina
US$0.073/kWh · Dominion SC / Duke / Santee Cooper

California is the target market for many of our readers, so it is worth knowing it sits at the expensive end on every axis: US$0.205/kWh modelled power, a 1.22× construction cost factor, a 48-month grid queue and no sales-tax exemption on equipment. Canadian provinces price in CAD: Manitoba C$0.055/kWh, British Columbia C$0.066 and Newfoundland and Labrador C$0.070 are the lowest.

Large-Load Tariffs and Minimum-Take Floors

Several utilities now bill large data centers for a minimum share of their contracted load whether they use it or not. The calculator applies these floors automatically above each threshold:

Virginia
Dominion GS-5, 25 MW+, 85% floor
Ohio
AEP Ohio data center tariff, 25 MW+, 85%
Georgia
Georgia PSC rule, 100 MW+, 80%
Indiana
I&M settlement, 70 MW+, 80%
Kansas, Missouri
Evergy large-load service, 75 MW+, 80%
New Jersey, Oregon
50 MW+ and 20 MW+, 80%

At low utilisation, a floor can raise the power bill by a third. Read the details in our Virginia, Ohio and Georgia tariff guides, or model it in the full configurator.

Frequently Asked Questions

How do you calculate data center power cost?

Multiply IT load by hours and utilisation, add cooling overhead of IT load times (PUE minus 1) times hours, then multiply the total MWh by the power rate. Apply any large-load minimum-take floor.

How much power does a 50 MW data center use?

About 442,380 MWh a year at 88% utilisation and PUE 1.13, roughly US$31.4M in Texas and US$90.7M in California.

What is the cheapest state for data center power?

In the SCR AI Build Configurator, Louisiana and New Mexico at US$0.065/kWh, followed by Oklahoma (US$0.068) and Texas (US$0.071).

What is a large-load minimum-take floor?

A tariff rule that bills large customers for a minimum share of contracted load (80% to 85% in the states modelled) even if they use less.

Does cooling affect data center power cost?

Yes. PUE sets the overhead: air cooling at PUE 1.40 uses about 27% more total power than direct-to-chip liquid at PUE 1.13 for the same IT load.
