Utility rates & providers in Williamson County, TN

Representative example: Franklin (1,000 kWh + 5,000 gal)

Williamson County is one of Tennessee’s most affluent counties and a major Nashville MSA suburb. Retail electric service for most Franklin-area and broader Williamson County addresses in our modeling is provided by Middle Tennessee Electric Membership Corporation (MTE), a TVA-affiliated cooperative whose residential Schedule RS tariffs combine access charges with per-kWh energy components and monthly TVA Fuel Cost Adjustment pass-throughs—effective energy rates can change monthly even when nominal rate sheets are stable.

FAQ

We use base charges and per-unit rates from official provider and municipal sources for each city in Williamson County. Electric uses city or provider tariff data; water, sewer, and trash use city or provider rate schedules. Each city page shows assumed usage (kWh, gallons) and source links.
Cities in the same county can have different electric providers, municipal water and sewer systems, and trash contracts. Rates and fee structures vary, so estimated monthly totals differ. Use the comparison table and city links to see details.
Each city page shows a 'last verified' date and links to official sources. Always confirm current rates on the provider's or city's website before making decisions.
No. Franklin’s published schedules apply to qualifying inside-city accounts. Other cities and utility districts in Williamson County bill separately—match the legal payee on your water bill.
We merge filings from Franklin’s coordinate and an unincorporated sample south of the city (35.720°N, 86.980°W) so acreage and equestrian-lot filings appear alongside in-town merges—FCC data is still address-specific.
