Energy Cost Benchmarking: How Does Your Illinois Business Compare to Industry Averages
Use energy cost benchmarking to see how your Illinois business compares to industry averages. Discover where you're overpaying and learn how to lower your commercial energy costs below the benchmark.
How much should your Illinois business be paying for electricity? Most business owners don't have a clear answer to that question—and that uncertainty is costing them money. Without a benchmark, there's no way to know whether your current rate is competitive, average, or significantly above what your peers are paying for similar operations.
Energy cost benchmarking is the practice of comparing your business's energy costs to industry averages, peer businesses, and market rates. It's a straightforward but powerful discipline that turns an abstract utility bill into an actionable performance indicator. And in Illinois's competitive deregulated energy market, the businesses that know their numbers consistently do better than those that don't.
This guide will show you what energy cost benchmarking is and why it matters, how Illinois commercial energy costs compare across industries, what the gaps between average and high-performing businesses typically look like, and how to use this knowledge to drive your costs below the industry average.
What Is Energy Cost Benchmarking and Why Every Illinois Business Owner Needs to Know Their Numbers
Energy cost benchmarking is the systematic process of comparing your business's energy performance—usage intensity, cost per square foot, cost per unit of output, or total energy spend as a percentage of revenue—against relevant external standards. Those standards might be industry averages, regional comparisons, peer business data, or established best practice benchmarks from organizations like the EPA's Energy Star program.
For Illinois businesses, benchmarking serves as a diagnostic tool. Just as a financial ratio analysis reveals whether your business is performing above or below industry norms on profitability, leverage, or liquidity—energy benchmarking reveals whether your energy costs are a competitive strength or a hidden liability.
What Good Energy Benchmarking Reveals
- Whether your energy cost per square foot or per unit of production is above or below industry average
- Whether your electricity rate per kWh is competitive in the Illinois deregulated market
- Which specific cost components (supply, demand charges, capacity, delivery) are driving above-average costs
- How your energy intensity compares to similar facilities in similar climates
- Where the biggest opportunities for cost reduction exist
The EPA Energy Star Benchmarking System
The EPA's Energy Star Portfolio Manager is the most widely used commercial building benchmarking platform in the United States. It allows building owners and operators to track energy and water consumption and compare performance to similar properties nationwide on a 1–100 scale. A score of 75 or above qualifies for Energy Star certification, representing the top 25% of similar buildings for energy efficiency. While this tool focuses on building energy intensity rather than procurement cost, it's a valuable starting point for understanding your performance baseline.
Illinois Commercial Energy Rates by Industry: See Exactly How Your Business Stacks Up Against the Competition
Different Illinois industries have very different energy profiles—and therefore different benchmarks. Here's an overview of typical energy cost characteristics by industry, drawing on EIA data and Illinois commercial energy market experience.
Illinois Commercial Energy Cost Benchmarks by Industry (Approximate)
| Industry | Typical Energy Cost % of Revenue | Energy Intensity (kWh/sq ft/yr) | Primary Cost Driver |
|---|---|---|---|
| Manufacturing (light) | 3–6% | 50–150 | Process electricity, compressed air |
| Manufacturing (heavy/metals) | 8–15% | 150–500+ | Electric arc, heat treatment |
| Food & Beverage Processing | 5–10% | 100–300 | Refrigeration, HVAC, processing |
| Healthcare/Hospitals | 2–4% | 200–400 | 24/7 HVAC, medical equipment |
| Retail (general) | 1–3% | 20–60 | Lighting, HVAC |
| Grocery/Supermarkets | 3–6% | 100–200 | Refrigeration, lighting |
| Hospitality/Hotels | 2–4% | 50–150 | HVAC, lighting, laundry |
| Warehousing/Logistics | 0.5–2% | 10–40 | Lighting, climate control |
| Office Buildings | 1–2% | 15–50 | HVAC, lighting, equipment |
| Data Centers | 5–15%+ | 500–2,000+ | IT equipment, cooling |
These ranges are broad because energy costs vary significantly within industries based on vintage of facility, operational practices, equipment age, and—critically—energy procurement strategy. A manufacturer at 8% energy-to-revenue ratio may be in the same industry as one at 4%, but the difference often reflects procurement sophistication and efficiency investment as much as operational differences.
Rate Benchmarks: What Illinois Businesses Should Be Paying Per kWh
Beyond intensity benchmarks, the raw rate per kWh is a useful comparison metric. Illinois commercial electricity rates across the state in 2025 range from approximately $0.085–$0.115/kWh all-in (supply plus delivery). Within those ranges, supply rates—the negotiable portion—typically fall between $0.045–$0.075/kWh depending on contract structure, term, and load profile. If your all-in commercial rate exceeds $0.115/kWh or your supply rate exceeds $0.075/kWh, you're likely paying above-market rates.
Hidden Energy Waste Revealed: The Shocking Gaps Between Average and High-Performing Illinois Businesses
The gap between average and top-performing Illinois businesses in energy management isn't just a matter of degree—it's a fundamentally different approach to energy as a strategic business variable.
The Procurement Gap
High-performing Illinois businesses actively manage energy procurement: they shop competitively at every renewal, use brokers to access multiple supplier quotes, negotiate contract terms, and monitor market conditions between renewals. Average businesses often haven't evaluated their supply rate in two or more years. This procurement gap alone typically represents 10–20% higher supply costs for average businesses.
The Demand Management Gap
Demand charges—the charges based on your peak 15-minute demand each month—represent 20–40% of many Illinois commercial electricity bills. High-performing businesses actively manage their peak demand through load scheduling, equipment sequencing, and automated controls. Average businesses have little awareness of their demand charge exposure, let alone strategies to reduce it. This gap can represent 10–25% of total electricity costs.
The Efficiency Investment Gap
Best-in-class Illinois businesses treat energy efficiency as a capital allocation decision with measurable ROI. They systematically identify, fund, and track efficiency projects—LED retrofits, HVAC upgrades, variable frequency drives, building automation systems. Average businesses address efficiency reactively, if at all. The cumulative usage reduction from systematic efficiency investment can reach 20–30% over a 5-year period.
