TX SB2321

Texas Commission on Environmental Quality (TCEQ) may waive emissions enforcement for electric generation facilities and on-site backup generators during grid emergency periods when an independent system operator (such as ERCOT) notifies the commission that additional power generation is needed

During declared grid emergencies, emissions limits, hours of operation limits, and similar operational standards may not apply to power generation facilities for the duration specified in the operator's notification

Facility owners must take "commercially reasonable steps" to operate environmental controls and minimize excess emissions during waiver periods, while maintaining operational records

Facilities must submit documentation to TCEQ including facility name, location, affected units, and details of any emissions events (date, time, pollutant type, quantity, and duration)

TCEQ retains discretion to pursue enforcement actions based on submitted documentation and other available information; the bill takes effect September 1, 2025
