SHORT DESCRIPTION:  Administration of PUC Substantive Rule 25.476, Renewable and Green Energy Verification

INTENDED AUDIENCE:  All Retail Electric Providers

DAY AFFECTED:  March 1, 2021

LONG DESCRIPTION:  This notice is to announce the continuing administration of PUCT Substantive Rule 25.476, Renewable and Green Energy Verification, for which ERCOT serves as the registration agent. This rule affects owners of generating facilities located in Texas and all Retail Electric Providers (REPs).

The purpose of PUCT Substantive Rule Section 25.476 is to establish the procedures by which REPs calculate and compose their renewable content pursuant to Section 25.475, General Retail Electric Provider Requirements and Information Disclosures to Residential and Small Commercial Customers, and to establish guidelines and verification for claims of “green” products.

The following deadlines affect REPs:

March 1, 2021 – Each REP that relies upon a supply contract with an out-of-state generator to authenticate fuel mix shall submit a report of the facility’s annual fuel mix to ERCOT. Additional detail can be found in Section 25.476 (f) (2).

March 15, 2021 – Each REP within Texas that markets “green” electricity for power generated from natural gas produced in Texas shall submit attestations to ERCOT from the generator that the natural gas used to generate electricity supplied to the REP was produced in Texas.  Additional information can be found in Section 25.476 (f) (1).

July 1, 2021 – Each REP shall update its Electricity Facts Label for each of its products. Additional detail can be found in Section 25.476(h).

No later than April 1, 2021, ERCOT will publish the fuel mix and environmental impact data for calendar year 2020 for each generation owner, including the percentage of MWh generated from each fuel source and the MWh-weighted average annual emissions rate. Additional details can be found in Section 25.476(e)(2). In addition, ERCOT will also calculate and publish the state average fuel mix, statewide system average emission rates for each type of emission, and a default scorecard to account for all generated electricity not authenticated by a Renewable Energy Credit no later than April 1, 2021. Additional details can be found in Section 25.476(e)(4).
