Relating to a study by the Public Utility Commission of Texas on the feasibility of constructing certain extra high voltage transmission lines.

SB 1665 requires the Texas Public Utility Commission (PUC) to conduct a study before approving construction of a specific 765-kilovolt transmission line for the Permian Basin Reliability Plan. The study must examine performance under different conditions, costs to ratepayers (especially residential customers), potential cost overruns, and supply chain/workforce constraints. The PUC must submit study results to an independent third party for review, but cannot use a third party previously hired by the project's developer after 2020. This bill directly affects the PUC's approval process for this transmission project and expires in 2029.
