The Virginia State Corporation Commission, in an Oct. 29 order, said that a hearing will convene on April 1, 2021, either in its second floor courtroom in Richmond, Va., or by electronic means, to receive testimony and evidence offered by the company, respondents, and staff on the Partial Line #2010 230-kV Single-Circuit Transmission Line Underground Pilot Project (Tysons-Future Spring Hill Substation).
As noted in the filing, Virginia Electric and Power d/b/a Dominion Energy Virginia in late September filed with the commission an application for certification of the project in Fairfax County, Va., with the project involving:
- Removing an approximate 0.56-mile segment of its existing overhead 230-kV Reston-Tysons Line #2010 from the Tysons substation to just south of the site for the future Spring Hill substation and to relocate and replace the line underground
- Completing work at the Tysons substation to allow that segment of Line #2010 to be relocated underground
- Building a transition pole just south of the future Spring Hill substation to transition Line #2010 from an underground line to an overhead line
The company requests that the commission approve the project as a project that qualifies as a line to be placed underground, in part, because the project meets all of the statutory requirements for the “Underground Pilot Program.”
The commission added that the company states that the desired in-service date for the project is Dec. 31, 2025, and that estimated conceptual cost of the project (in 2020 dollars) is about $30.4m, including about $22.6m for underground transmission line-related work, about $0.70m for overhead transmission line-related work, and about $7.10m for substation-related work.
Commission staff is to file testimony on the project by Feb. 19, 2021; interested persons may file comments on the company’s application by March 26, 2021; and a hearing for the receipt of testimony from public witnesses on the project will convene on March 31, 2021, the commission said.
