Relating to distributed energy resources.

HB 3346 requires Texas electric utilities to modify service rules to allow residential customers to use certified meter socket adapters for rooftop solar panels and home battery systems. It defines "distributed energy resources" to include residential solar, storage, and smart devices that adjust electricity use during grid events. The bill creates a pilot program (Project 53911) enabling aggregated small-scale systems (up to 160 megawatts for energy markets) to participate in Texas' wholesale electricity markets without geographic restrictions. This primarily affects homeowners installing home energy systems, utilities required to adopt new rules, and the regulatory commission overseeing the pilot.
