Public Service Commission - Transmission Line Siting - Limitations

SB 853 prohibits the Public Service Commission from authorizing new overhead transmission line construction unless an applicant proves existing power line paths are insufficient. It requires developers to demonstrate that current transmission corridors cannot accommodate new lines before approval. The bill also limits local governments from conditioning permits on approvals like "conditional use" or "special exception" for new power lines. This directly affects utility companies seeking to build new transmission infrastructure and local governments issuing construction permits. The law takes effect July 1, 2025.
