Electric Transmission line routing is the process electric utility companies use to determine where new high-voltage power lines will be placed. These lines form part of the broader electrical grid that carries power across long distances. Routing decisions identify which properties will be affected and where easements must be secured.

Typically, a utility will study numerous possible routes and then file a formal application with the Public Utility Commission of Texas (PUC). The application filing includes maps, environmental studies, and proposed routes. Once submitted, the PUC begins a proceeding to decide which route will ultimately be approved.
