NOTICE TYPE: M-A110526-02 Operations

SHORT DESCRIPTION: NDCRC API MOTE access for QSE test request submissions

INTENDED AUDIENCE: Qualified Scheduling Entities with NDCRC access

DAYS AFFECTED: November 5, 2026 - November 13, 2026

LONG DESCRIPTION: NDCRC API MOTE access to support the programmatic submission of QSE Test Requests to ERCOT entered market testing on November 5, 2026 and is scheduled to go live in production on November 13, 2026. The existing web application interface will remain live, so migrating to the API for any QSE with existing NDCRC access is completely optional. No new credentials are needed to authenticate using the API - the same QSE user certificates that are compatible with the existing web application are all that is required.

ACTION REQUIRED: If your organization is interested in performing market testing, please download the attached NDCRC API Quickstart guide from this notice for further instructions on how to integrate with the market testing (MOTE) environment.  

ADDITIONAL INFORMATION: Digital certificates with the QSE_W or QSE_R roles can be requested through your organization's USA and are required for access in their respective environments (market testing certificates cannot be used in production and production certificates cannot be used for market testing).

CONTACT: If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via email at ClientServices@ercot.com.
