S.B. No. 1664 introduces new requirements for transmission and distribution utilities in Texas regarding rate changes. The bill mandates that utilities provide a stand-alone document with each rate change filing that details the proposed changes for each rate class, the duration of the changes, anticipated revenue impacts, current and future delivery charges for average residential customers, and the differences between these charges. Additionally, if a regulatory authority proposes a different rate change than what was initially filed, the utility must submit a new document reflecting the updated information. The bill also requires the Public Utility Commission to maintain and regularly update information about utility rates on its website in a format that is easily understandable to the public.

The changes outlined in this bill will only apply to proceedings that commence on or after its effective date of September 1, 2025. Any proceedings that began before this date will continue to be governed by the existing laws at that time. This legislation aims to enhance transparency and public understanding of utility rate changes, ensuring that consumers are well-informed about the financial implications of such changes.
