What does Texas SB1664 do?
SB 1664 mandates that all Transmission and Distribution Utilities (TDUs) submit a specific, consumer-facing "stand-alone document" with every rate change application to increase transparency. This requirement creates a strict dual-filing obligation—once at the initial filing and again immediately prior to final order approval—affecting all rate proceedings commencing on or after September 1, 2025. Implementation Timeline Effective Date: September 1, 2025 Compliance Deadline: September 1, 2025 (Applies to any Statement of Intent or rate change application filed on or after this date).
