Dept. of Energy Designates Transmission
Line Corridor in Loudoun
On May 8th the U.S. Department of Energy released a list of potential “priority” corridors for the construction of new or expanded transmission lines. According to the Loudoun Times Mirror (5-9-2024). “One possible corridor includes existing transmission rights-of-way across Loudoun County along with a new path through western Loudoun.”
The corridors are designated by the Department of Energy as National Interest Electric Transmission Corridors, or NIETCs.
The designation is significant for several reasons. One, it permits federal financing, including direct loans for the construction of transmission lines within the corridors. In addition, because of the NIETC designation, both State and Federal regulators will have the authority to override local government regulations regarding the location of the transmission lines. With the NIETC designation, the Virginia State Corporation Commission (SCC) will have the authority to override Loudoun’s carefully developed zoning regulations, historic designations, and conservation easements restricting the placement of transmission lines.
Furthermore, if the Va. SCC were to deny a proposed transmission route through Western Loudoun, the applicant could still apply to the Federal Energy Regulatory Commission (FERC) to override the SCC decision.
NextEra, a Florida based energy company has applied for NIETC designation for the construction of a 500 KV transmission line – known as the MidAtlantic Resiliency Link (MARL). According to the Loudoun Times Mirror NextEra’s line “would connect the proposed Woodside substation outside Winchester near the West Virginia border, travel through western Loudoun, and end at the proposed Aspen substation outside Leesburg near Cochran Mill Road. The line would span 130 miles across Virginia, West Virginia, Pennsylvania, and Maryland.”
NextEra has not released specifics about the proposed route and has not yet filed an application with the State Corporation Commission.
A 500 KV transmission line requires massive towers and significant land clearing for both construction and maintenance (see accompanying photo).
There is considerable public concern about the impact of the line on the Blue Ridge Mountains and the local environment. Friends of the Blue Ridge Mountains has joined numerous other environmental and conservation organizations in Loudoun County in the formation of the Loudoun Transmission Line Alliance (LTLA).
The objective of the LTLA is to minimize the impacts on the environment, culture, and economy of the new transmission lines. To minimize the damage, the LTLA’s position is that all transmission lines should be built within existing power corridors as opposed to constructing new corridors.
The Loudoun County Board of Supervisors (BOS) has adopted the same position. At the April 16th business meeting, the Loudoun BOS unanimously adopted a resolution encouraging the use of existing transmission line corridors for the new Mid Atlantic Resiliency Link (MARL).
Because of the NIETC designation the Federal Energy Regulatory Commission (FERC) will have the authority to override any restrictions or conditions Loudoun County, or the Commonwealth of Virginia may wish to place on the location of the transmission lines.
There is a 45-day public comment period on the NIETC designation. Comments may be submitted through June 24 by emailing NIETC@hq.doe.gov.
Friends has formed an internal MARL Working Group and will be developing a policy position regarding the NIETC designation over the next several weeks. If you would like to work with our MARL Working Group, please contact FBRM’s Executive Director, Larry Malone, at 703/709-1066. |
