Virginia Senate introduces $24M pilot program for underground electric transmission lines

On November 18, 2024, Virginia State Senator Perry and Delegate Subramanyam introduced Senate Bill 708, aimed at establishing a pilot program for underground electric transmission lines. This legislative proposal seeks to enhance the understanding of underground transmission systems, focusing on their reliability, construction methods, and economic benefits.

The bill proposes the construction of two qualifying electrical transmission line projects, specifically those rated between 230 and 500 kilovolts, with the option to build portions underground. Notably, the bill allows for the approval of a specific project that has been pending since December 31, 2017, which involves a 5.3-mile transmission line that will utilize both overhead and underground facilities. The underground segment is expected to span approximately 3.1 miles and is designed to be constructed within or adjacent to interstate highway rights-of-way.

Key provisions of the bill include a streamlined approval process for public utilities, which will not require extensive technical analyses for the underground construction segment. The bill also mandates that the Virginia State Corporation Commission approve the underground construction within 30 days of a utility's request, provided there is local community support.

The introduction of SB 708 has sparked discussions regarding its potential economic implications, particularly in promoting economic development through improved electric reliability. However, concerns have been raised about the environmental impacts and the adequacy of the review process, as the bill limits further analysis of the proposed routes.

As the bill progresses through the legislative process, it is expected to face scrutiny from environmental advocates and local communities concerned about the implications of underground construction. Proponents argue that the pilot program could pave the way for more sustainable energy infrastructure in Virginia, while opponents caution against the potential oversight of environmental considerations.

The bill has been referred to the Committee on Commerce and Labor for further examination, where it will undergo discussions and possible amendments before any voting takes place. The outcome of SB 708 could significantly influence the future of electric transmission infrastructure in Virginia, marking a pivotal moment in the state's energy policy.
