NERC Reliability Standards define the reliability requirements for planning and operating the bulk power system (BPS). These standards are developed by the industry using the process described in Appendix 3A of the Rules of Procedure: The Standard Processes Manual. Texas RE actively participates in the process by commenting and voting on proposed new or revised Reliability Standards. In addition, Texas RE maintains awareness of upcoming enforceable standards and provides outreach as needed.

For information on NERC Reliability Standards, visit the NERC website:

Interested entities may participate in the development process in a variety of ways:

  1. The Reliability Standards development process is governed by Appendix 3A of the Rules of Procedure, Standard Processes Manual. At a high level, an interested party submits a Standard Authorization Request (SAR), industry drafts the Reliability Standard, industry comments and votes on the draft Reliability Standard. The Reliability Standard is then put forth for approval with the NERC Board of Trustees and ultimately is filed with FERC for approval.

  2. Texas RE strongly encourages stakeholders to understand and participate in the active projects. This is an opportunity to ensure the reliability of the grid. Stakeholders may vote and submit comments on each project.

  3. Texas RE encourages stakeholders to participate on Standard Drafting Teams, listen to webinars, attend NERC workshops, and participate in the regional NERC Standards Review Forum (NSRF) monthly meetings.

Texas RE Subject Matter Experts have assembled information pertaining to the following enforceable standards:

Standards Review Checklist

One approved Regional Standard is enforceable in the ERCOT Interconnection.

FERC approved Regional Standard BAL-001-TRE-1, Primary Frequency Response in the ERCOT Region, on January 16, 2014. This Regional Standard became effective on April 1, 2014.

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. Texas RE follows its approved Standards Development Process in the development of Regional Reliability Standards.

If you wish to request a Regional Reliability Standard, please complete a Standard Authorization Request (SAR) and send it to the Reliability Standards Manager.

The Members Representative Committee (MRC) reviews SARs and subsequent recommendations for the development, revision, or deletion of Regional Standards and variances. A Standard Drafting Team (SDT) then drafts the standard. Once drafted, a proposed Regional Standard or variance is approved by the MRC. Please see the Standards Development Process for more information.

On January 29, 2019, FERC approved the retirement of Regional Standard IRO-006-TRE-1: IROL and SOL Mitigation in the ERCOT Region. The standard was effective from July 1, 2012 until January 29, 2019.

The NERC Standards Review Forum (NSRF) is a stakeholder group reporting to the Member Representatives Committee (MRC). The purpose of the NSRF is to provide a regional stakeholder forum for discussion, collaboration, and research on NERC Standard Authorization Request forms (SARs), standards under development, interpretations, and existing Reliability Standards. The NSRF may also provide advice and recommendations to the MRC regarding the development of ERCOT Interconnection Regional Standards and variances. The NSRF will provide regular updates to the MRC to assist the MRC in regional industry analyses of standards being developed and balloted by NERC.

Additionally, the NSRF serves as a forum for stakeholders to share information regarding compliance with NERC Reliability Standards. Topics for discussion may include:
  • Best compliance practices
  • Audit experiences
  • Violations and possible violations of standards
  • Lessons learned
  • Industry policies, direction, and trends
  • Current compliance-related events and programs of general interest
  • Compliance with new or modified NERC Reliability Standards
  • The ERCOT protocols and Guides as they relate to NERC requirements
