SHORT DESCRIPTION: Instructions Regarding 16 Texas Administrative Code 25.186 submissions available at ercot.com for REPs and TDSPs

INTENDED AUDIENCE: TDSPs and LSEs

DAYS AFFECTED: April 30, 2025 and May 15, 2025

LONG DESCRIPTION: Per the requirements in 16 Texas Administrative Code (TAC) §25.186, Goal for Average Total Residential Load Reduction, no later than 45 days following the end of each calendar quarter, a Retail Electric Provider (REP) (as described by 16 TAC 25.186) providing a responsive device program within the ERCOT region must submit to ERCOT the following information for the previous quarter:

• 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;
• the start and end dates of the ESI ID's participation; 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

By March 31st each year, ERCOT is required to file a report with the Public Utility Commission of Texas summarizing data submitted by REPs pertaining to their responsive device programs.  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/Distribution Utility load management program under 16 TAC §§25.181-183.  Therefore, in order to complete the required report, ERCOT requires data from both REPs and Transmission / Distribution Service Providers (TDSPs). 

The applicable instructions regarding data submission are available here for REPs: https://www.ercot.com/files/docs/2025/04/14/Instructions_Quarterly_Residential_DR_Data_Submission_REP.docx
