Public Utilities - Alternatives to Construction of New Transmission Lines
Summary
SB 483 expands when the Maryland Public Service Commission must look at alternatives before approving a new electric transmission line. Under current law, the Commission must examine alternatives in limited circumstances involving an existing transmission line that is convenient to the service area or would best promote economic and efficient service. The bill broadens that review to include additional reasons for avoiding a new line, including preserving historical, environmental, or agricultural areas and avoiding impacts on land in planned growth areas or land zoned for residential or mixed use with a residential component.
The bill also clarifies what counts as an alternative to new transmission construction. In addition to using an existing transmission line owned by another company, the Commission would consider using an existing right-of-way, reconductoring an existing transmission line, or undergrounding a transmission line. It further specifies that, when evaluating these alternatives, the Commission does not need to consider whether the owner of an existing line has a franchise in the service area. The act would take effect October 1, 2025.
Impact
SB 483 would amend Section 7-209 of the Public Utilities Article to require a broader alternatives analysis in transmission-line siting cases. The practical effect is to give the Public Service Commission more explicit authority and direction to consider non-new-build options and to weigh land-use and preservation concerns more heavily when reviewing proposed transmission projects. Utilities seeking new transmission infrastructure could face a more extensive review process, while communities, landowners, and local governments in preservation areas, planned growth areas, and residential or mixed-use zones would gain additional statutory protection from new overhead line routes.
Sentiment
Based on the bill text and sponsorship, the measure appears to reflect a pro-local-control and land-preservation sentiment, with support from a group of senators concerned about transmission-line siting impacts. Because there are no committee transcripts or recorded votes provided, there is no documented debate in the supplied materials showing formal support or opposition. The bill’s framing suggests an intent to encourage less disruptive infrastructure planning rather than to block transmission development outright.
Contention
The main point of contention is likely to be the balance between transmission expansion and land-use/preservation concerns. Supporters would favor requiring the Commission to consider alternatives that reduce impacts on historical, environmental, agricultural, and residential areas, while utilities and proponents of faster grid buildout may argue that the expanded review could complicate or delay needed infrastructure projects. Another likely issue is the bill’s removal of the need to consider whether an existing line owner has a franchise in the service area, which could be seen as making it easier to rely on existing infrastructure owned by another company.
