A surprisingly high Tampa Electric (TECO) bill can be alarming, but there's usually a logical explanation. TECO serves the Tampa Bay area and Hillsborough County, where hot, humid summers drive significant air conditioning usage.
Before assuming something is wrong, it helps to understand the factors that legitimately cause bills to vary month-to-month. Most high bills aren't errors—they're the result of predictable factors that aren't always obvious.
Storm Recovery Charges
TECO includes storm recovery surcharges to fund infrastructure improvements after hurricane damage. These charges were increased in January 2026 by approximately $8.88 per 1,000 kWh.
This is a legitimate charge approved by the Florida Public Service Commission, but it does increase your overall bill. For a household using 1,200 kWh monthly, this adds roughly $10-11 to your bill.
Seasonal Usage Patterns
Florida's climate means most households run air conditioning 8-10 months per year. Summer bills (June-September) are typically 40-60% higher than winter bills due to increased cooling demand.
- Winter (Dec-Feb): $100-150/month average
- Shoulder (Mar-May, Oct-Nov): $130-180/month average
- Summer (Jun-Sep): $180-280/month average
A household using 1,000 kWh in winter might use 1,500-2,000 kWh in summer just from increased AC runtime.
Rate Structure
TECO uses a tiered rate structure where the first block of usage is charged at a lower rate, and additional usage is charged at higher rates. The standard Residential Service (RS) rate ranges from approximately 14-18 cents per kWh depending on usage tier and current fuel adjustments.
The fuel charge appears as a separate line item and fluctuates based on natural gas prices. Like all Florida utilities, TECO passes through fuel costs to customers dollar-for-dollar.
How to Check If Your Bill Is Accurate
Before assuming your bill is wrong, verify a few things:
- Compare to the same month last year — Weather patterns vary, so comparing to the same season gives a better baseline than comparing to last month.
- Check your meter reading — TECO bills show the current and previous meter readings. Subtract to verify the kWh usage matches what's shown.
- Review rate changes — TECO's rates changed in January 2026. If you're comparing to bills from 2025, the rate difference alone could explain a 5-10% increase.
- Look for estimated reads — If your bill shows "EST" or "Estimated," the actual usage may differ from what was billed.
