SHORT DESCRIPTION:  ERCOT Membership Application for 2026 Membership Year Now Available Online

INTENDED AUDIENCE:  Entities interested in becoming 2026 ERCOT Members

DAY AFFECTED:  November 7, 2025

LONG DESCRIPTION:  On September 29, 2025, ERCOT notified all 2025 ERCOT Members via email that the ERCOT Membership Application and Agreement (Application) for the 2026 Membership Year is now available online for completion. The Application for the 2026 Membership Year may be accessed through ERCOT's Public Portal at Annual Membership Request.

Market Participants may become, but are not required to be, ERCOT Members, subject to the requirements of the ERCOT Bylaws. A Member Applicant may join as a Corporate, Associate or Adjunct Member. Corporate Membership includes the right to vote on matters submitted to the general Membership, such as election of Technical Advisory Committee (TAC) Representatives and members of TAC subcommittees.

ERCOT Membership terms are for no more than one Membership Year and do not renew automatically. The 2026 Membership Year begins on January 1, 2026, and ends on December 31, 2026. To become an ERCOT Member for the 2026 Membership Year, an authorized representative of the applying entity must complete and electronically sign the Application online, pay the applicable Annual Member Dues required by ERCOT Bylaws Section 3.4, and receive written confirmation of approval from ERCOT. 

Electronic funds transfer instructions will be attached to the autogenerated confirmation of receipt email that the Applicant Contact receives after submission of the online Application. Annual Member Dues are payable as follows:

Any Member may request that the Member's Annual Member Dues be waived for good cause shown. Annual Member Dues are not prorated even if Membership is approved by ERCOT after the 2026 Membership Year has begun.

The announcement of the members of the Technical Advisory Committee (TAC) for the 2026 year will occur at the fifty-fifth Annual Membership Meeting on December 8, 2025 (Annual Meeting). In accordance with the ERCOT Bylaws, the Record Date for 2026 ERCOT Corporate Members to vote in the 2026 TAC Representatives Elections is Friday, November 7, 2025. Your entity would have to be approved in writing by ERCOT as a Corporate Member for the 2026 Membership Year 2026 no later than the Record Date of November 7, 2025.

Given that the Application must be reviewed by ERCOT for approval, those interested in applying for Membership should do so well in advance of November 7, 2025, to avoid potential delays that could affect the start date of Membership (such as questions related to Segment eligibility and requests for additional information). All Applications for the 2026 Membership Year shall be submitted online at Annual Membership Request. When registering as a new user, users are required to verify their email address after submitting the Sign Up form before they can proceed with the Application. Alternatively, if you log into ERCOT's Public Portal you can find the Application by searching for "Annual" or "Member" in the search bar on the landing page. If you are experiencing login issues using your email address or have technical questions and need support regarding the portal, please contact portalsupport@ercot.com. Attached is the ERCOT Public Portal Registration Guide to assist you with registration.

ADDITIONAL INFORMATION:  ERCOT Membership will post an updated 2026 ERCOT Members document to Membership (ercot.com) by close of business every Friday until the Record Date. Please note, final approval of the 2026 Membership Application and Agreement is dependent upon several variables, such as submitting correct information on the application form, timely responses to follow-up questions by Membership staff, and timely payment of Membership dues.

Please note that being registered as a Market Participant is independent from being a Member. Membership is completely optional and does not interfere with your Market Participant status. For more information or to obtain a copy of the ERCOT Bylaws and Certificate of Formation, please visit ERCOT's website at http://www.ercot.com/about/governance.

Other related Membership information, including a link to the online portal for Membership Applications, are posted on the Membership page of the ERCOT website at http://www.ercot.com/about/governance/members.
