Relating to the provision of certain electricity services.

HB 4800 amends Texas Utilities Code to clarify what constitutes "transmission service" and streamline municipal consent for utility infrastructure. It redefines transmission service to exclude grid management services (like voltage control and operating reserves) provided by power generators after customer choice implementation, shifting responsibility to transmission operators. The bill also requires municipalities to respond within 90 days to utility requests for building or expanding transmission facilities (including substations), with automatic approval if they fail to act. This directly affects electric utilities seeking infrastructure permits and Texas municipalities managing local land use.
