Understanding the Basics
Your commercial utility bill contains critical information that directly impacts your bottom line. Most businesses pay their bills without understanding what they're actually paying for—leaving thousands of dollars in potential savings on the table.
- Account information and meter readings
- Rate schedule and tariff codes
- Usage charges vs. demand charges
- Taxes, fees, and surcharges
Demand Charges: The Hidden Cost
Demand charges can represent 30-70% of your total bill, yet most businesses don't understand how they work. These charges are based on your peak energy usage during a billing period—even if that peak only lasted 15 minutes.
- Peak demand is measured in kilowatts (kW)
- One spike can affect your bill for months
- Load management can dramatically reduce these charges
- Time-of-use rates affect when demand is measured
Power Factor: The Efficiency Penalty
If your power factor falls below 90%, you may be paying a penalty. Power factor measures how efficiently your facility uses electricity. Poor power factor means you're drawing more current than necessary to do the same work.
- Power factor correction equipment can eliminate penalties
- Typical payback period: 1-2 years
- Improves overall electrical system efficiency
- Reduces strain on electrical infrastructure
Rate Schedule Optimization
You may be on the wrong rate schedule for your usage pattern. Utilities offer different rate structures optimized for different consumption profiles. A rate analysis could reveal significant savings with no changes to your operations.
- Time-of-use rates reward off-peak usage
- Demand response programs offer bill credits
- Interruptible service rates provide discounts
- Seasonal rates vary throughout the year
