Business energy for engineering and CNC machining
CNC machines, compressed air and extraction create heavy, shift-based electricity demand. For larger shops, when you use power matters almost as much as how much.
How engineering workshops and CNC use energy
- CNC machining centresLarge motors and spindles, often on long cycles.
- Compressed airExpensive to generate. Leaks and idle running add up.
- Extraction and coolant systemsRun alongside machining.
- Welding and fabricationHigh peaks on three-phase supplies.
- Space heatingLarge workshops with high ceilings.
Things to consider when buying
- Larger shops are often half-hourly metered, so your daily profile affects pricing.
- Check the agreed supply capacity (kVA) on HH supplies, as it carries its own charges.
- If you're adding machines or shifts, tell the energy expert. Some contracts limit changes in use.
Questions
What is half-hourly data?
A record of your electricity use every 30 minutes. See half-hourly data.
Does running night shifts change my price?
On half-hourly supplies, yes. Use at different times costs different amounts, so share your shift patterns.
What is a capacity charge?
A daily charge based on the agreed supply capacity (kVA). Check it matches your real peak demand.
