The project involves a crucial 13-mile line through Loudoun County, which is nearing the end of expected life and requires replacement to maintain reliability.
Aging infrastructure - This line was built in the mid-1960s and the structures are approaching the end of their expected service life.
Growth in local and regional demand - Dominion Energy's service territory continues to be one of the fastest growth areas in PJM and Loudoun County.
- Reduces the risk of a major failure of the high-voltage network
- Improves local and regional electric reliability
- Increases capacity of the lines through the corridor
Dominion Energy's service territory continues to be one of the fastest growth areas in PJM and Loudoun County is still experiencing above average electrical growth, primarily driven by data center development. The proposed Loudoun-Pleasant View 500kV Rebuild Project reduces the risk of a major failure of the region's high-voltage network without the need to obtain additional easements.
Approval is required by the Virginia State Corporation Commission (SCC). An application was filed with the SCC in October 2013 and approval for construction was provided by the SCC Final Order received April 28, 2014.
For more information on construction activities on the eastern half of this same corridor, refer to the Brambleton-Mosby Project.
The south terminal substation for the new line will be Mosby (adjacent to Loudoun) and the north terminal substation will be Goose Creek (near Pleasant View). At the conclusion of the project, the rebuilt 500 kV Loudoun-Pleasant View Line #558 will be split and renamed as Brambleton-Goose Creek Line #558 and Brambleton-Mosby Line #590.
