Relating to renewable energy generation facilities.

HB 3580 prohibits Texas and its political subdivisions from offering new economic or tax incentives for the construction, maintenance, or operation of renewable energy facilities (like wind and solar power plants). It allows existing incentives under pre-existing agreements to continue but blocks renewal of those incentives after the bill's effective date. The bill also creates a new permit requirement for renewable facilities selling energy at wholesale, applying to wind and solar projects regardless of prior agreements. This directly affects renewable energy developers seeking state or local financial support for new projects.
