Transmission Line Siting - Comprehensive Plan, Recommendation, and Reporting Requirements

HB 645 requires all Maryland counties and Baltimore City to update their comprehensive plans to include an "electric system planning element" by January 1, 2026. This element must identify transmission line corridors, plan for future high-energy use facilities, and prioritize underground lines where feasible to minimize new infrastructure. Electric companies serving these areas must report annually to local governments on their compliance with these planning requirements, and the Public Service Commission must consider county recommendations when reviewing transmission line projects. The bill directly affects local governments, electric utilities, and the state's permitting process for transmission infrastructure.
