Over 12,000 company reviews
Texas has over 1,300 machine shops, and unlike most businesses their bill is driven by motors and equipment: CNC machines, lathes and mills, and the compressed-air system behind the whole shop. Below is what machine shops use and pay. See related guides for print shops and auto repair shops, or browse all commercial electricity guides by business type.
Key Takeaways
- A typical Texas machine shop uses about 10,000–25,000 kWh a month (roughly $850–$2,100 at ~8.3¢/kWh).
- Machine tools (CNC, mills, lathes) are the biggest load, with compressed air next.
- Compressed air is often the most wasteful system in a shop - leaks add up fast.
- HVAC and lighting round out the bill.
- Compressor efficiency, LED, and a competitive fixed rate are the biggest levers.
Machine Shop Electricity Snapshot
Figures are estimates for a typical shop. See methodology and sources below.
What It Costs to Run a Machine Shop
A machine shop's electricity tracks its equipment and how many hours it runs. CNC machines and conventional tools are the core load, and the air compressor that powers tooling, clamping, and blow-off runs alongside them - often the single most wasteful system if it has leaks.
Estimated usage & bill by shop size
| Shop size | Approx. sq ft | Monthly usage | Est. monthly bill* |
|---|---|---|---|
| Small shop | ~3,000 | 4,000–8,000 kWh | $330–$660 |
| Typical shop | ~8,000 | 10,000–25,000 kWh | $850–$2,100 |
| Large / production | 20,000+ | 30,000–60,000+ kWh | $2,500–$5,000+ |

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.
Machines, Compressed Air, and Climate
Machine tools and compressed air are the heart of the bill, with HVAC and lighting behind them.
| System | Why it draws power | Approx. share | Est. cost / month* |
|---|---|---|---|
| Machine tools (CNC, mills, lathes) | Spindles, drives, and coolant pumps | 35–45% | $490–$630 |
| Compressed air | Feeds tooling, clamping, and blow-off | 15–20% | $210–$280 |
| HVAC & ventilation | Cooling the shop and exhausting fumes | 15–20% | $210–$280 |
| Lighting | Shop floor and offices | 10–15% | $140–$210 |
| Welding & other | Welders, finishing, and misc. | 5–10% | $70–$140 |
*Illustrative split of a ~$1,400/month shop bill. Compressed-air leaks can quietly add hundreds of dollars a month.
How Spindles and Compressors Set the Peak
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
- Fix compressed-air leaks and right-size the compressor - the highest-value shop fix.
- Stagger machine startups so spindles and drives don't all inrush together.
- Use a VFD compressor to match air output to demand.
- Watch your interval data to find the monthly peak.
Demand Response for Machine Shops
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 Machine Shops Cut Energy Costs
- Lock in a fixed commercial rate. Comparing 30+ Texas providers at the right time is usually the biggest single lever.
- Fix compressed-air leaks. Air leaks are one of the biggest and most fixable wastes in any shop.
- Right-size and VFD the compressor. Matching air output to demand cuts a steady load.
- Switch to LED. LED shop-floor lighting cuts energy and adds less heat for HVAC.
- Maintain HVAC and ventilation. Efficient cooling and exhaust keep the shop comfortable at lower cost.
- Review demand and interval data. Knowing your peak kW shows whether a different rate structure would save money.

Frequently Asked Questions
How much electricity does a machine shop use in Texas?
A typical Texas machine shop uses about 10,000 to 25,000 kWh per month, or roughly $850 to $2,100 at the state's average commercial rate of about 8.3¢ per kWh. Large production shops use more.
What uses the most electricity in a machine shop?
Machine tools - CNC machines, mills, and lathes - are the biggest load, followed by the compressed-air system, then HVAC and lighting. Compressed air is often the most wasteful system because of leaks.
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.
How can a machine shop lower its electricity bill?
Fix compressed-air leaks and right-size (or add a VFD to) the compressor, stagger machine startups, switch to LED, maintain HVAC and ventilation, and lock in a competitive fixed rate.
Do machine shops pay demand charges?
Often yes. When several machines cut at once and the compressor loads while HVAC runs on a hot afternoon, the peak in kilowatts is billed by a demand charge across the month.
What is demand response and can a machine shop earn from it?
Demand response pays businesses to reduce use during short summer grid-peak windows. A shop can shift non-urgent jobs or heavy air use and ease HVAC during a peak window in exchange for bill credits.
