Local Providers
San Antonio utility providers: CPS Energy & SAWS
San Antonio is served by CPS Energy for electricity and natural gas, and by SAWS (San Antonio Water System) for water and wastewater. Some areas outside SAWS territory are served by special utility districts including East Central SUD.
Unlike most of Texas, CPS Energy is a municipal utility — not part of the deregulated retail electricity market. Residents don't shop for an electric provider; rates are set publicly by the city-owned utility and approved by the City Council.
FAQ
San Antonio utility cost FAQ
What's a normal CPS Energy bill in San Antonio?
Based on 126 community submissions, the average electric bill in San Antonio is $131/month. Bills run higher in summer due to AC load — CPS Energy is a municipal utility (not deregulated), so rates are set publicly.
How much is the average SAWS water bill?
The average SAWS bill across 126 community submissions is $66/month. SAWS combines water, wastewater, and trash on a single bill for most San Antonio addresses.
Why is my San Antonio electric bill so high in summer?
Cooling. South Texas summers regularly hit 100°F+ for weeks, and air conditioning drives the bulk of residential electric use. CPS Energy's standard residential rate also has a higher summer block (June–September) than winter — so you pay more per kWh on top of using more.
Are utilities included in San Antonio rentals?
Across 126 San Antonio submissions, 39 reported some utilities included in rent. Most rentals require tenants to pay CPS Energy and SAWS separately — some apartment complexes include water and trash. Confirm with your landlord before signing.
