H.B. No. 3511 introduces new provisions to the Texas Utilities Code regarding the interconnection of electric vehicles (EVs) to the ERCOT power grid. The bill adds Section 39.9161, which defines key terms such as "electric vehicle" and "interconnection." It empowers the commission to establish safety, technical, and performance standards for EVs that wish to connect to the electricity distribution system. In developing these rules, the commission is required to consider existing standards from recognized organizations, including the Underwriters Laboratories and the National Electrical Code.

Additionally, the bill allows the commission to create a program enabling the sale of electricity stored in EVs back to the transmission grid and distribution system. This includes provisions for electric utilities or retail electric providers to contract with EV owners, ensuring that the value of the electricity sold is credited to the owners. The legislation also facilitates the participation of electric vehicles in ERCOT market mechanisms, such as ancillary services and Virtual Power Plants, thereby integrating them as valuable assets within the power grid. The act is set to take effect on September 1, 2025.
