For a manufacturer, electricity is more than a building expense. Motors, compressed air, process cooling, and production schedules can change both energy use and the way a commercial account is billed. A useful savings review starts with the plant’s operating data, then checks whether its supply contract still fits.
1. Build a Clear Baseline
Collect at least 12 months of electricity bills, the current supply agreement, and the plant’s shift schedule. Record total kWh, billed demand where shown, and any recurring pass-through charges. Flag months with overtime, seasonal production, or equipment changes. Two plants with similar monthly kWh can have different costs if one concentrates more of its use into a short peak.
Ask the operations team to identify the largest loads. According to ENERGY STAR’s guidance for small and medium manufacturers, motor systems are a major electricity use in many industrial facilities, followed by process equipment, HVAC, and lighting. Your actual mix depends on what you make.
2. Look for Compressed-Air Waste
Compressed air is convenient, but leaks and equipment running through idle periods can add avoidable consumption. Walk the system when the production floor is quiet, log leaks for repair, and check whether compressor controls match the plant’s real schedule. Setpoints and process changes should be reviewed by maintenance and production staff so quality and safety remain protected.
3. Separate Energy Use From Peak Demand
Electricity usage is measured in kilowatt-hours. Demand reflects how much power a facility draws over a shorter interval. Some commercial tariffs and contracts have charges linked to demand or other load characteristics. If multiple large machines start together, shifting their startup times may help, but only when the applicable billing structure supports it. The Department of Energy’s rate guide explains why a facility should model the effect on its actual charges before making a change.
4. Compare Offers Against the Plant You Operate Today
A rate quote based on last year’s load may be misleading if the business added a line, changed shifts, or expects new equipment. Ask each supplier to model the same projected start date and usage profile. Compare the full delivered cost, treatment of delivery and other pass-through charges, term, early termination terms, and what happens after the contract ends. Our article on working with a broker versus buying directly explains the procurement options.
5. Prepare for an Energy Review
- Twelve recent bills for each plant meter.
- The current contract and expiration date.
- A list of planned equipment additions or shift changes.
- Any interval data available from the provider or utility.
- The person who can explain production constraints.
A 30-Day Manufacturing Electricity Plan
Week 1: Establish the baseline
- Collect bills, contract terms, and shift schedules.
- Record monthly kWh, billed demand, and total cost by meter.
- Note production changes that make last year an imperfect comparison.
Week 2: Walk the plant
- Review compressed-air leaks and idle equipment.
- Check motor maintenance, HVAC schedules, and lighting left on outside active zones.
- Identify any high-load equipment that starts at the same time.
Week 3: Test operational changes
- Prioritize repairs and schedule changes approved by operations.
- Measure consumption after each change rather than assuming a savings figure.
- Document any quality, safety, or production constraints.
Week 4: Review procurement
- Confirm the contract expiration date and notice requirements.
- Compare equivalent supply offers using the updated load profile.
- Assign someone to review the first bill after a new agreement begins.

The Bottom Line
Manufacturers get the clearest picture when production and procurement teams work from the same data. Fixing waste inside the plant and comparing contracts against the actual load are complementary decisions.

Frequently Asked Questions
What uses the most electricity in a manufacturing plant?
It depends on the process. Motors, compressed air, process heating or cooling, HVAC, and lighting are common areas to investigate. Start with metered data and equipment hours rather than applying another plant’s percentages.
Will fixing compressed-air leaks reduce my bill?
It can reduce electricity use if the compressor system responds to the lower load. The dollar effect depends on controls, operating hours, energy prices, and whether demand charges also change. Measure the result.
Should a plant choose the lowest quoted cents per kWh?
Compare projected total cost and risk, including delivery treatment, demand exposure, pass-through charges, usage provisions, term, and expiration language.
