NOTICE DATE: February 4, 2025

NOTICE TYPE: W-A020425-01 General Operations

SHORT DESCRIPTION: Generation Information Needed for Renewable and Green Energy Verification with a DocuSign process for Emissions Reporting where the Generation is EPS metered

INTENDED AUDIENCE:  All Owners of Generation in Texas

DAYS AFFECTED: March 1, 2025 

LONG DESCRIPTION:  As the registration agent specified in the Public Utility Commission of Texas's rule16 Texas Administrative Code (TAC) § 25.476, Renewable and Green Energy Verification, ERCOT requests that all generation owners submit certain emissions, generation output, and fuel mix information for all of their generation units in Texas, as required by 16 TAC § 25.476, for the purposes of creating individual generator scorecards and calculating statewide fuel and emissions data used in updating Electricity Facts Labels for Retail Electric Providers (REPs). 

By March 1, 2025, all generation owners shall submit the following data for all of their generation units in Texas for calendar year 2024 to ERCOT: 

• For all ERCOT Polled Settlement (EPS) metered generation units:
• Generation owners shall submit the MWh-weighted average annual emissions rate, on an aggregate basis, for each of the following emission categories: carbon dioxide, nitrogen oxides, particulates, sulfur dioxide, and nuclear waste using a DocuSign process. EPS metered Generators do not need to submit their net generation output and fuel mix information as this information is available in ERCOT’s settlement system.  The emissions data will be requested using a DocuSign process and the files requesting that data are planned to be distributed on February 5, 2025.  The files will be distributed to the Authorized Rep who can assign the DocuSign envelope to the appropriate responder.    

• For all generation units that are not EPS metered:
• Generation owners shall submit the MWh-weighted average annual emissions rate, on an aggregate basis, for each of the following emission categories: carbon dioxide, nitrogen oxides, particulates, sulfur dioxide, and nuclear waste. 
• Generation owners shall also submit the net generation in MWh and fuel mix information.  Information on appropriate categorization of fuels for purposes of Electric Facts Labeling is provided on the instruction tab of the attached spreadsheet to be used to submit this information.  Please note that there is no change to the reporting process that has been used in the past for units that are not EPS metered.

ACTION REQUIRED: All generation owners should submit the required information by March 1, 2025. For generators that are not metered with EPS meters, use the attached spreadsheet named “2024 Generators with NO EPS Meters.” The form is attached to this email and are also available on the Labeling of Electricity page of ERCOT.com. This form is submitted to ElectricityLabel@ercot.com.  For Generators with EPS Meters, a DocuSign envelope will be distributed on February 5, 2025 to the Authorized Representative.

ADDITIONAL INFORMATION: For more information on 16 TAC § 25.476, please visit the page on the PUCT's website.
