CPS Energy (City Public Service Board of San Antonio)
CPS Energy is the nation's largest municipally owned natural gas and electric utility, serving about 962,000 electric customers across San Antonio and Bexar County plus portions of seven surrounding counties in Texas. The utility offers two managed-charging bill-credit programs, EV Off-Peak Rewards and EV Smart Rewards, which pay customers a one-time enrollment credit plus a monthly credit for charging outside weekday peak hours, either manually or through automated smart charging; no dedicated EV time-of-use rate or hardware rebate program is currently active. CPS Energy customers cannot switch to a competing retail provider because San Antonio is served by a municipal utility exempt from Texas retail electric deregulation.

Managed-charging programs
EV Off-Peak Rewards
Residential customers self-manage their own charging schedule. Participants earn a one-time $30 bill credit at enrollment and a $5 monthly credit for charging at home off-peak. The peak window is Monday through Friday, 4 pm to 10 pm. CPS Energy says customers without an eligible vehicle or charger can still join this program, so it is the option for customers who do not qualify for the automated EV Smart Rewards program.
$30 one-time enrollment credit plus $5/month for self-managed off-peak charging
EV Smart Rewards
Residential customers enroll in automated smart charging managed by WeaveGrid, which schedules charging around a set departure time and battery level to favor off-peak hours. Participants earn a one-time $30 bill credit at enrollment and a $10 monthly credit. Enrollment is limited to qualifying Tesla, Jeep, Toyota, and Lexus EVs and plug-in hybrids (and a few other models) or approved home chargers from ChargePoint, Emporia, or Wallbox. Launched in June 2026.
$30 one-time enrollment credit plus $10/month for automated WeaveGrid-managed charging
CPS Energy does not offer an EV-specific time-of-use rate or an EV hardware rebate. Current residential rates are published in the Residential Electric rate schedule linked in the sources below. The EV Off-Peak Rewards and EV Smart Rewards programs are bill-credit programs for charging outside weekday peak hours.
CPS Energy's primary EV incentives are two bill-credit programs. EV Off-Peak Rewards pays a one-time $30 bill credit at enrollment plus $5 per month for charging at home off-peak; the peak window is Monday through Friday, 4 pm to 10 pm. CPS Energy says customers without an eligible vehicle or charger can still join it. EV Smart Rewards, which launched with WeaveGrid in June 2026, pays the same $30 enrollment credit plus $10 per month for enrolling in automated charging that WeaveGrid schedules around off-peak hours, but it is limited to qualifying Tesla, Jeep, Toyota, and Lexus EVs and plug-in hybrids (and a few other models) or approved ChargePoint, Emporia, or Wallbox home chargers. Both are behavioral incentives, not hardware rebates: there is no cash back for purchasing or installing an EVSE. CPS Energy lists no commercial or multifamily EVSE rebate program.
CPS Energy is a community-owned municipal utility overseen by a board of trustees appointed by the San Antonio City Council, not an investor-owned utility subject to the Texas Public Utility Commission. San Antonio is inside ERCOT's geographic footprint but is served by a municipal utility that is exempt from retail electric deregulation, meaning there are no competing retail providers and customers cannot shop for a better rate. Texas does not have a statewide right-to-charge law protecting EV owners in HOA or condominium communities, so whether a homeowner can install an EVSE in a shared building depends on the association's governing documents, not state statute.
