CPS Energy (City Public Service Board of San Antonio)

CPS Energy does not offer an EV-specific time-of-use rate. Residential customers, including EV owners, are served under the standard Residential Electric (RE) rate, a flat energy charge with a summer peak capacity component that applies above a monthly usage threshold. There is no off-peak discount window, no separate overnight EV tier, and no opt-in time-of-use rate for residential accounts. Current rates are published in the RE rate schedule linked in the sources below. The utility has stated it does not plan to introduce a standalone EV rate in the near term, though the EV Off-Peak Rewards and EV Smart Rewards programs function as a behavioral substitute.

CPS Energy's primary EV incentives are two bill-credit programs launched with WeaveGrid on June 24, 2026. EV Off-Peak Rewards pays a one-time $30 bill credit at enrollment plus $5 per month in any month the customer charges at home at least once and avoids the peak window (Monday through Friday, 4 pm to 10 pm); it is open to any residential EV or plug-in hybrid owner regardless of vehicle make or charger brand. EV Smart Rewards 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 Tesla, Jeep, Toyota, and Lexus EVs and plug-in hybrids paired with a ChargePoint, Emporia, or Wallbox home charger; customers without an eligible vehicle or charger can still use EV Off-Peak Rewards. Both are behavioral incentives, not hardware rebates: there is no cash back for purchasing or installing an EVSE. No commercial or multifamily EVSE rebate program has been identified from Tier-1 or Tier-2 sources as currently active.

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.
