NOTICE DATE: August 24, 2023

NOTICE TYPE: M-A082423-01 Operations

SHORT DESCRIPTION: TCEQ Enforcement Discretion Beginning at Noon Today

INTENDED AUDIENCE: QSEs and Resource Entities with Generation Assets

DAYS AFFECTED: August 24, 2023

LONG DESCRIPTION: ERCOT anticipates high system demand today, August 24, 2023 through Sunday, August 27, 2023 due to extremely hot temperatures 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. TCEQ’s enforcement discretion will apply beginning at noon today. Unless TCEQ provides notice otherwise, the period of enforcement discretion will continue until ERCOT issues a Market Notice indicating that ERCOT’s request for enforcement discretion has ended. ERCOT will end its request for enforcement discretion when ERCOT determines that this discretion is no longer necessary to ensure sufficient generation supply, and such a determination could occur earlier or later than Sunday, August 27, 2023, depending on grid conditions.

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.
