NOTICE DATE: August 29, 2023

NOTICE TYPE: M-A082923-01 Operations

SHORT DESCRIPTION: TCEQ Enforcement Discretion From 2 p.m. to Midnight on August 29 and 30, 2023

INTENDED AUDIENCE: QSEs and Resource Entities with Generation Assets

DAYS AFFECTED: August 29 and 30, 2023

LONG DESCRIPTION: ERCOT anticipates high system demand during the afternoon and evening hours today and tomorrow due to hot temperatures across the ERCOT Region.  ERCOT has also experienced a high level of unexpected thermal generation outages and continues to forecast a lower than usual level of wind generation output across the ERCOT Region.  To ensure as much generation as possible is available to serve system demand, ERCOT has requested that the Texas Commission on Environmental Quality (TCEQ) exercise its enforcement discretion with respect to generator exceedances of TCEQ air permit limitations. TCEQ has communicated to ERCOT that it will use its enforcement discretion in evaluating generation facility exceedances of emission and operational permit limits to maximize generation availability.  Unless TCEQ provides notice otherwise, TCEQ’s enforcement discretion will apply from 2 p.m. until midnight today, August 29, 2023 and tomorrow, August 30, 2023. 

Any generation facility operator that expects to exceed its air permit limits to assist during this period shall document its activities and provide notice to Kelly Cook ([log in to unmask]), Deputy Director of Critical Infrastructure Division for TCEQ.

Please refer to the “Procedure for Requesting TCEQ Enforcement Discretion Relating to a Power Emergency in Texas for ERCOT, MISO, or SPP Regions,” available at https://www.tceq.texas.gov/downloads/response/enforcement-discretion.pdf.
