TX SB1641

Requires the Public Utility Commission to adopt rules prohibiting transmission or distribution service providers from including projected retail demand additions of 25 megawatts or more at a single delivery point in ERCOT load forecasts unless customers demonstrate they are reasonably likely to use electricity at the stated level, location, and date

Customers can demonstrate demand likelihood through evidence of property lease/legal interest, a security deposit refundable only upon energization at the forecasted level, an attestation confirming demand details, or another commission-approved method

Transmission or distribution service providers must submit attestations to ERCOT with each load forecast certifying that customers associated with large demand additions have met demonstration requirements

ERCOT cannot include projected large demand additions in transmission planning analyses used for determining transmission need unless the service provider submits required attestations and provides all requested information to the commission or ERCOT

Competitively sensitive information provided under these requirements is confidential and exempt from public disclosure under the Texas Public Information Act

Effective September 1, 2025
