Texas has over 1,400 data processing and hosting businesses, and data centers are the most power-dense facilities in commercial real estate: the servers draw huge, constant power, and cooling has to remove every watt of it as heat. Below is what data centers use and pay, and where the power goes. See related guides for warehousing & storage and cold storage, or browse all commercial electricity guides by business type.
Key Takeaways
- Data-center power ranges from a server room (~30,000–150,000 kWh/month) to a large facility (millions of kWh).
- IT equipment is ~45–55% of the bill, and cooling ~30–40%.
- Efficiency is measured as PUE (total power ÷ IT power); ~1.4–1.8 is typical.
- Texas's low commercial rates make it a major data-center hub.
- Cooling optimization, containment, and a competitive contract are the biggest levers.
Data Center Electricity, by the Numbers
Figures are estimates that scale with IT load; small server rooms and hyperscale sites fall well outside this range.
Why Data Centers Use So Much Power
A data center's electricity is driven by its IT load - servers, storage, and networking that run at full power 24/7 - plus the cooling needed to remove all that heat. The ratio of total power to IT power is the facility's PUE; the lower it is, the less overhead you're paying to cool and distribute power.
Estimated usage & bill by facility size
| Facility size | Typical IT load | Monthly usage | Est. monthly bill* |
|---|---|---|---|
| Server room / small IT | ~50–200 kW | 30,000–150,000 kWh | $2,500–$12,500 |
| Mid-size data center | ~1–3 MW | 500,000–2,000,000 kWh | $40,000–$165,000 |
| Large / hyperscale | 10+ MW | 5,000,000+ kWh | $415,000+ |
*Electricity portion at Texas's ~8.3¢/kWh average commercial rate. Large facilities negotiate custom contracts; demand charges are significant at every size.
How does the Texas commercial rate compare?
Texas businesses pay an average of about 8.3¢ per kWh - roughly 38% below the U.S. commercial average of ~13.5¢. Because Texas is deregulated, you can shop the supply portion of your bill across 30+ retail providers and lock in a fixed rate - compare current commercial electricity rates.
Servers and the Cooling to Match
Two things dominate a data center's bill - the IT equipment itself, and the cooling that removes its heat - with power-distribution losses making up most of the rest.
| System | Why it draws power | Approx. share of the electric bill |
|---|---|---|
| IT equipment | Servers, storage, and networking at full load 24/7 | 45–55% |
| Cooling | CRAC/CRAH units, chillers, and fans removing heat | 30–40% |
| Power distribution & UPS | Conversion and battery-backup losses | 8–12% |
| Lighting & other | Facility lighting and building systems | 2–5% |
Shares reflect a typical PUE of ~1.5; a more efficient facility spends proportionally less on cooling and distribution.
Demand Charges at Data-Center Scale
Most of your bill is energy — the total kilowatt-hours (kWh) you use over the month. But many commercial accounts also carry a demand charge, billed on your single highest peak of power draw, measured in kilowatts (kW), usually over a 15-minute interval. It doesn't matter only how much electricity you use, but how fast you use it at your busiest moment.
How to keep demand charges down
- Lower PUE with containment, higher setpoints, and economizer (free) cooling.
- Manage power factor to avoid penalties on a large, steady load.
- Use batteries/UPS and on-site generation to shave demand during peak events.
- Sub-meter and trend IT and cooling loads to target inefficiency.
Demand Response and On-Site Power
Demand response is a program where businesses agree to reduce their electricity use for short windows when the Texas grid (ERCOT) is under strain — typically late afternoons on the hottest summer days. In exchange, participating businesses earn payments or bill credits.
Where Data Centers Cut Energy Costs
- Lock in a competitive contract. At data-center scale, a well-structured energy contract is a major lever.
- Lower your PUE. Hot/cold-aisle containment, higher supply-air temps, and economizers cut cooling overhead.
- Optimize cooling controls. Variable-speed fans and pumps and smart controls match cooling to IT load.
- Refresh IT efficiency. Newer servers do more work per watt; virtualization reduces idle load.
- Manage power factor and demand. Correction and peak management cut demand-related charges.
- Consider on-site generation/storage. Batteries and generation improve resilience and shave peaks.

Frequently Asked Questions
How much electricity does a data center use in Texas?
It ranges enormously. A small server room uses about 30,000 to 150,000 kWh per month, a mid-size data center 500,000 to 2,000,000 kWh (about $40,000 to $165,000 at ~8.3¢ per kWh), and large or hyperscale facilities use millions of kWh.
What uses the most electricity in a data center?
The IT equipment itself - servers, storage, and networking running at full load 24/7 - is about 45 to 55% of the bill, and cooling to remove that heat is about 30 to 40%. Power distribution and UPS losses make up most of the rest.
What is the average commercial electricity rate in Texas?
Texas businesses pay an average of about 8.3¢ per kWh as of 2026, roughly 38% below the U.S. commercial average of about 13.5¢. Your actual rate depends on your ZIP code, utility (TDU), usage, and when you sign your contract.
What is PUE and why does it matter?
PUE (Power Usage Effectiveness) is total facility power divided by IT power. A typical value is about 1.4 to 1.8; the closer to 1.0, the less overhead you pay for cooling and power distribution. Lowering PUE is the main way to cut a data center's non-IT energy.
How can a data center lower its electricity bill?
Lower PUE with hot/cold-aisle containment, higher supply-air temperatures, and economizer cooling; optimize cooling controls; refresh IT for efficiency; manage power factor and demand; and lock in a competitive contract.
Do data centers participate in demand response?
Many do. Without compromising uptime, facilities use batteries, UPS, and on-site generation to ride through ERCOT peak events, earning demand-response payments while supporting grid reliability.
