Why Is My Commercial Electric Bill So High?7 Hidden Costs Draining Your Budget
Quick Summary
- • Florida businesses overpay 15-40% on electricity bills
- • 7 hidden costs: wrong rate, demand charges, inefficiencies, missing rebates
- • Free 5-minute audit identifies your specific issues
- • Average savings: $50,000-$150,000 annually
- • Reading time: 12 minutes
If your Florida business is spending $10,000+ monthly on electricity, you're likely overpaying by $1,500-$4,000 every single month. That's $18,000-$48,000 in annual losses that could go straight to your bottom line instead.
After analyzing 500+ Florida commercial electric bills, we've discovered that most businesses pay far more than necessary due to hidden costs they don't even know exist. The worst part? Your utility company won't tell you about these issues.
In this guide, you'll discover the 7 most common (and expensive) reasons commercial electric bills are high, plus exactly how to fix each one. By the end, you'll know:
- ✅ Why your bill is actually high (the specific reasons)
- ✅ How much you're overpaying (and where)
- ✅ What to do about it (actionable solutions)
- ✅ How much you can realistically save (with real examples)
1.You're on the Wrong Utility Rate Schedule
The Problem: 60% of Florida businesses are on the wrong rate schedule, costing them 5-15% more than necessary. Utilities don't automatically switch you to cheaper rates—you have to request it.
How Rate Schedules Work
Florida utilities (Duke Energy, FPL, TECO) offer multiple rate schedules:
- •General Service Demand (GSD): Standard rate for most businesses. Includes demand charges based on peak usage.
- •Time-of-Use (TOU): Lower rates during off-peak hours (nights/weekends), higher during peak (weekdays 12-8pm).
- •Interruptible Service (IS): Significant discounts in exchange for allowing utility to curtail power during emergencies.
Real Example: Manufacturing Facility Saves $31,000/Year
Company: Tampa metal fabrication shop
Original rate: GSD (General Service Demand)
Monthly bill: $8,200
Problem: 70% of operations ran during off-peak hours, but paid peak rates
Solution: Switched to Time-of-Use rate
Savings: $2,600/month → $31,200/year
Implementation cost: $0 (free rate change)
ROI: Immediate
2.Demand Charges Are Killing You
The Shocking Truth: For most commercial customers, 30-70% of your electric bill is demand charges, not energy consumption. Yet most business owners have no idea what these charges are or how to reduce them.
What Are Demand Charges?
Demand charges bill you for your peak electricity usage (kW) during any 15-minute interval in the month, separate from your energy consumption (kWh).
Example Calculation:
Peak demand at 2:47 PM on July 15th: 500 kW
Duke Energy demand rate: $11.50 per kW
Monthly demand charge: 500 × $11.50 = $5,750
This is separate from energy (kWh) charges and applies for the entire month based on a single 15-minute peak.
Why This Matters: If five pieces of equipment happen to run simultaneously for just 15 minutes, you pay the demand charge for that peak level all month—even if it never happens again.
Real Example: Tampa Warehouse Reduces Demand by 230 kW
Company: Distribution warehouse, Tampa
Original peak demand: 850 kW
Demand charge: $9,775/month
Problem: HVAC, forklifts, and conveyor systems all started simultaneously
Solution: Staggered equipment start times + load monitoring
New peak demand: 620 kW
Savings: $2,645/month → $31,740/year
Implementation cost: $0 (operational changes only)
3.Time-of-Use Penalties During Peak Hours
Hidden Cost: If you're on a Time-of-Use (TOU) rate but operating during expensive peak hours, you could be paying 2-3x more per kWhthan necessary.
Peak vs Off-Peak Pricing
| Time Period | Rate (Duke Energy) | Difference |
|---|---|---|
| Off-Peak (9pm-7am, weekends) | $0.058/kWh | Baseline |
| Mid-Peak (7am-12pm, 8pm-9pm) | $0.092/kWh | +59% higher |
| Peak (12pm-8pm weekdays) | $0.143/kWh | +147% higher |
Real Example: Cold Storage Warehouse Shifts Schedule
Company: Refrigerated warehouse, Jacksonville
Problem: Heavy freezer/cooling loads running during peak hours
Monthly consumption: 120,000 kWh
Before: 60% usage during peak hours → $11,400/month
Solution: Pre-cooled during off-peak, reduced peak usage to 20%
After: Most usage shifted to off-peak → $7,400/month
Savings: $4,000/month → $48,000/year
Implementation: Programmable thermostats + operational scheduling
4.Power Factor Penalties (5-15% Hidden Surcharge)
What It Is: Power factor measures how efficiently your business uses electricity. A low power factor (below 0.95) means you're wasting energy, and utilities charge you extra for it.
⚠️ Common in Businesses With:
- •Electric motors (HVAC compressors, pumps, fans)
- •Old fluorescent lighting with magnetic ballasts
- •Arc welding equipment
- •Induction heating systems
The Cost
Most Florida utilities apply a 5-15% surcharge when power factor drops below 0.95. For a $10,000/month bill, that's $500-$1,500/month in unnecessary charges.
Real Example: Manufacturing Plant Installs Capacitors
Company: Metal fabrication shop, Tampa
Power factor: 0.78 (very poor)
Monthly penalty: $1,200
Solution: Installed power factor correction capacitors
New power factor: 0.97 (excellent)
Savings: $1,200/month → $14,400/year
Equipment cost: $8,500
Payback period: 7 months
ROI: 169% in year one
5.Inefficient Equipment (HVAC & Lighting)
Equipment Energy Consumption: HVAC and lighting typically account for 50-70% of commercial electric costs. Old, inefficient systems can waste 30-50% of that energy.
LED Lighting: Fastest ROI
| Type | Watts | Annual Cost | Lifespan |
|---|---|---|---|
| T12 Fluorescent | 75W | $66/year | 15,000 hrs |
| T8 Fluorescent | 32W | $28/year | 20,000 hrs |
| LED | 18W | $16/year | 50,000 hrs |
💡 Available Rebates for LED Retrofits:
- Duke Energy: $20-$50 per LED fixture
- FPL: $15-$35 per fixture
- TECO: $15-$30 per fixture
- Federal Tax Credit: Section 179D - up to $1.80/sqft
HVAC: Biggest Energy User
Commercial HVAC systems account for 30-50% of total electricity use. Units older than 10 years can be 30-40% less efficient than modern high-efficiency systems.
Real Example: Office Building Upgrades HVAC + Lighting
Company: 25,000 sqft office building, Orlando
Monthly electric bill: $6,800
Upgrades:
- • Replaced 200 fluorescent fixtures with LED → $4,200 rebate
- • Upgraded 3 rooftop HVAC units (14 SEER → 18 SEER) → $2,400 rebate
Total project cost: $32,000
Rebates received: $6,600
Net cost: $25,400
Monthly savings: $1,850
Annual savings: $22,200
Payback period: 13.7 months
25-year ROI: 2,087%

Duplicate Charges
Same fee charged twice, or old accounts not closed properly.
Incorrect Demand Charges
Peak demand billed higher than actual meter reading shows.
⚠️ Real Error Found: $47,000 Overcharge
Company: Manufacturing facility, Jacksonville
