Relating to the generation of electric power for sale by a water supply or sewer service corporation.

This bill allows water supply and sewer service corporations operating within ERCOT (Texas' electric grid) to register as power generators and sell electricity. It directly affects these public utility corporations by enabling them to generate revenue from electricity sales. The key provision requires that all revenue from power sales must be used exclusively to cover the costs of power generation (like equipment, fuel, and maintenance) or for purposes specified under existing water service laws. The bill does not change how these corporations operate their core water or sewer services.
