Regional Reliability Standards

There are two approved regional standards in the Electric Reliability Council of Texas (ERCOT) region.

BAL-001-TRE-1, Primary Frequency Response in the ERCOT Region, was approved by the Federal Energy Regulatory Commission (FERC) on January 16, 2014. This regional standard became effective on April 1, 2014.

IRO-006-TRE-1, IROL and SOL Mitigation in the ERCOT Region, was approved by FERC on May 31, 2012. This regional standard became effective on July 1, 2012.

Please refer to the Regional Reliability Standards Development section for information on the process and to access current Standard Drafting Team efforts.

Texas Reliability Entity, Inc. (Texas RE) regional reliability standards will apply to the reliable operation and planning of the bulk-power system (BPS) in the ERCOT region. Future regional standards published in this section will apply to entities in the ERCOT region whose functional North American Electric Reliability Corporation (NERC) registration appears in the list of applicability associated with each standard, regardless of membership in the region. Regional reliability standards are approved by the Texas RE Board, NERC, and FERC and become part of the body of NERC Reliability Standards.

Regional reliability standards provide for as much uniformity as possible relative to NERC Reliability Standards. The regional reliability standards go beyond, add detail to, or implement NERC Reliability Standards, or cover matters not addressed in NERC Reliability Standards.
