5 Strategies to Reduce Manufacturing Energy Costs Without Cutting Production

The Manufacturing Energy Challenge

Energy is often the second or third largest operating cost for manufacturing facilities, after labor and raw materials. Yet many manufacturers view energy as a fixed cost, missing significant optimization opportunities.

Here are five proven strategies to reduce energy costs without impacting production.

1. Demand Response Revenue

Convert your operational flexibility into revenue. Manufacturing facilities typically have these curtailable loads:

• HVAC systems: Pre-condition spaces before events
• Compressed air: Reduce pressure or use stored air capacity
• Batch processes: Schedule around peak periods
• Material handling: Pause non-critical conveyors
• Lighting: Reduce warehouse and parking lighting

Typical savings: $50,000 – $500,000+ annually in new revenue

2. Peak Demand Management

Your monthly demand charge is based on your single highest 15-minute consumption period. Strategies to reduce peaks include:

• Load staggering: Sequence equipment startups
• Production scheduling: Avoid running all lines simultaneously
• On-site generation: Run backup generators during peaks
• Battery storage: Install batteries to shave peaks

Typical savings: 15-30% reduction in demand charges

3. Power Factor Correction

Many manufacturers pay penalties for poor power factor (the ratio of real to apparent power). Large motors, VFDs, and welding equipment often cause poor power factor.

Installing capacitor banks or active power factor correction can:

• Eliminate power factor penalties
• Reduce apparent power consumption
• Free up electrical capacity

Typical savings: 5-10% of total electricity bill

4. Compressed Air Optimization

Compressed air is often called the “fourth utility,” and it’s expensive. Common inefficiencies include:

• Leaks: The average plant loses 25-30% of compressed air to leaks
• Over-pressurization: Running at higher pressure than needed
• Inefficient compressors: Older units use 20-40% more energy

Addressing these issues can reduce compressed air costs by 20-50%.

Typical savings: $20,000 – $200,000 annually

5. Process Heat Recovery

Manufacturing processes generate significant waste heat that can be captured and reused:

• Preheat combustion air: Use exhaust heat to warm incoming air
• Heat process water: Reduce boiler fuel consumption
• Space heating: Redirect waste heat to facility heating
• Power generation: Organic Rankine Cycle systems for larger facilities

Typical savings: 10-25% reduction in thermal energy costs

Implementation Approach

We recommend a phased approach:

1. Assessment: Identify opportunities and quantify savings
2. Quick wins: Implement demand response and peak management first
3. Capital projects: Plan larger investments like power factor correction
4. Continuous improvement: Monitor and optimize ongoing
