How to lower your business electricity cost
- Check your rate schedule. Utilities put businesses on rate classes by size and usage. Ask your utility whether another schedule, such as a time-of-use rate, fits how you use power.
- Manage demand charges. If your bill has a demand charge, it is set by your highest short burst of usage in the month. Staggering when large equipment starts can lower it.
- Compare supply offers. Check the price per kWh, contract length, early-termination fees and what happens when the contract ends before you sign.
