NOTICE TYPE: M-B041526-01 Operations

SHORT DESCRIPTION: Request for data concerning Demand Response capabilities - Q1 2026

INTENDED AUDIENCE: REPs and TDSPs

DAYS AFFECTED: January 1 - March 31, 2026

LONG DESCRIPTION: Under 16 Texas Administrative Code (TAC) Section 25.186, Goal for Average Total Residential Load Reduction, a Retail Electric Provider (REP) with a responsive device program must submit the following data to ERCOT quarterly, using ERCOT's prescribed form, within 45 days after each calendar quarter ends:

• the electric service identifier (ESI ID) for each residential customer with smart appliances or devices enrolled in each responsive device program offered by the REP; and
• the date of each demand response event, including each demand response event start time and stop time and the ESI IDs deployed for each event

ERCOT must file an annual report with the Public Utility Commission of Texas summarizing REP smart appliance and device program data. The requirement states that those responsive device programs must not allow participation of a residential customer that is enrolled in an emergency program such as a Transmission and Distribution Utility load management program under 16 TAC Sections 25.181-183.  To complete this report, ERCOT requires data from both REPs and Transmission and Distribution Service Providers (TDSPs). 

The applicable forms and instructional documents for quarterly data submission for REPs and TDSPs are located at https://www.ercot.com/services/programs/load under "Key Documents".  Detailed formatting instructions can be found in ERCOT Protocols Section 22, Attachment T.

ACTION REQUIRED: ERCOT will send initial email notices (via DRSURVEY@ercot.com) to Authorized Representatives and associated contacts of applicable entities by the end of this week (April 17, 2026). 

REPs that receive a notice email must respond to ERCOT's email upon receipt, stating whether they have a responsive device program.  REPs with programs must submit Q1 2026 data to ERCOT by May 15, 2026.

TDSPs that receive a notice email must respond to ERCOT's email upon receipt, stating whether they have a load management program.  TDSPs with programs must submit Q1 2026 data to ERCOT by May 15, 2026.
