Bill Summary · HB 3511

Legislative bill overview

HB 3511 allows electric vehicles to participate in ERCOT's (Electric Reliability Council of Texas) energy markets, enabling EV owners and operators to potentially sell stored energy back to the grid during peak demand periods. The bill creates a regulatory framework for vehicle-to-grid (V2G) technology participation in Texas's wholesale electricity market.

Why is this important

This legislation positions Texas to leverage distributed energy resources from its growing EV fleet, potentially improving grid reliability and resilience during high-demand periods while creating new revenue opportunities for EV owners. It reflects broader national efforts to integrate renewable and flexible energy sources into aging grid infrastructure.

Potential points of contention

  • Grid safety and technical standards: Unclear whether existing ERCOT protocols can reliably manage bidirectional power flows from thousands of distributed vehicle batteries without destabilizing the network
  • Consumer protection gaps: Vehicle owners may face battery degradation costs or liability issues if discharge cycles accelerate wear, with unclear responsibility allocation between drivers, utilities, and manufacturers
  • Market fairness concerns: Individual EV owners may lack negotiating power against utility companies, and participation barriers (compatible vehicle models, home charging infrastructure) could create equity disparities in who benefits financially
