Public Utilities - Alternatives to Construction of New Transmission Lines

SB 483 requires Maryland's Public Service Commission to evaluate alternatives to building new transmission lines whenever specific conditions are met, such as preserving historical, environmental, or agricultural areas, or avoiding conflicts with planned residential zones. The bill expands the Commission's review to include options like using existing utility corridors, reconductoring older lines, or undergrounding existing infrastructure instead of constructing new routes. This directly affects utility companies planning new transmission projects and the Commission, which must now consider these alternatives before approving new construction. The law applies to all new transmission line projects within Maryland starting October 1, 2025.
