Relating to the interconnection and integration of distributed energy resources.

SB 2021 establishes new requirements for connecting small-scale renewable energy systems to Texas' electric grid. It defines "distributed energy resources" (like rooftop solar, home batteries, or electric vehicles supplying power) and creates a new "aggregated" category for groups of these systems (each under 1.5 megawatts) operated as one unit. Owners must register as power generation companies with the state commission to sell electricity wholesale through the grid, streamlining access for smaller producers. This primarily affects homeowners, small businesses, and community energy projects seeking to connect their renewable systems to the broader electric grid.
