Relating to reliability requirements for certain electric generation facilities.

HB 3356 modifies reliability requirements for specific electric generation facilities in Texas' ERCOT power grid. It applies to facilities with a standard interconnection agreement that have operated for at least one year and are not self-generators. The bill changes the deadline for the first reliability demonstration from the original date to January 1, 2027, while repealing prior provisions related to this requirement. The law takes effect September 1, 2025, directly affecting owners and operators of qualifying power plants in ERCOT.
