TX SB388

Establishes a legislative goal that 50% of new generating capacity installed in the ERCOT power region after January 1, 2026, must come from dispatchable generation sources (excluding battery energy storage)

Requires the Public Utility Commission to establish a dispatchable generation credits trading program, which must be activated by January 1, 2027, if dispatchable generation falls below 55% of new installed capacity

Awards nuclear generation facilities a "compliance premium" equal to one additional dispatchable generation credit per megawatt, effectively doubling their credit value compared to other dispatchable sources

Requires ERCOT to establish a tracking system for dispatchable generation credits and file annual compliance reports by September 15, with the commission notifying entities of their credit requirements by January 15

Exempts power generation companies that exclusively operate battery energy storage resources from the dispatchable generation credits requirements and purchasing obligations
