AUSTIN, Texas — Austin Energy is expanding its at-home electric vehicle charging program to include General Motors vehicles.

The Power Partner Electric Vehicle program now covers several GM models, including the Cadillac Escalade IQ, Chevrolet Blazer EV and GMC Hummer EV.

The program helps the power grid during peak demand periods in summer. Austin energy can temporarily slow charging speeds at home chargers during high-energy events, but drivers can override the setting anytime.

Participants get $50 when they sign up and $25 each year for staying in the program.

Tesla vehicles were already part of the program.

Any electric vehicle can join if owners use approved charging stations from ChargePoint, EVoCharge or Emporium.

Austin Energy said the expansion supports the city’s clean energy goals while giving drivers financial incentives.

“Adding GM’s electric vehicle lineup to Power Partner EV is a significant step toward creating a more flexible, sustainable electric grid,” said Richard Genece, Austin Energy vice president for Customer Energy Solutions. “By enrolling in the program, EV drivers can directly contribute to Austin’s clean energy goals while earning incentives.”
