Virginia regulators to hold public evidentiary hearing in April 2020 regarding Dominion’s proposed 230-kV switching station

The commission said that any person or entity may participate as a respondent in the proceeding by filing a notice of participation by Feb. 28, 2020

A public evidentiary hearing on Virginia Electric and Power’s d/b/a Dominion Energy Virginia application for approval of a project that includes a new 230-kV switching station will be held on April 14, 2020, in the Virginia State Corporation Commission’s second-floor courtroom in Richmond, Va., the commission said in a Dec. 17 order.

As noted in the order, the company on Dec. 2 filed with the commission an application for a certificate of public convenience and necessity to build and operate in Loudoun County, Va., the new 230-kV Evergreen Mills switching station on land owned by the customer; a new approximately 0.6-mile, 230-kV, double-circuit loop of the company’s existing 230-kV Brambleton-Yardley Ridge Line #2172 on new right of way (ROW), supported by seven structures, from a tap point along those lines — the Evergreen Mills Junction — to the Evergreen Mills switching station — the #2172 Loop; and a new approximately 0.6-mile, 230-kV, double-circuit loop of the company’s existing 230-kV Brambleton-Poland Road Line #2183 on new ROW, supported by nine structures, from the Evergreen Mills Junction to Evergreen Mills switching station — the #2183 Loop.

The company proposes to build the project in two parts, the commission said, adding that the company proposes to first acquire the 160-foot ROW for the full project, build the Evergreen Mills switching station, and build the #2172 Loop (Part A). The second part of the project would consist of the construction of the #2183 Loop and the installation of the remaining breakers at the Evergreen Mills switching station (Part B).

The commission added that Dominion states that the project is to serve load growth of the “Data Center Alley” in Loudoun County; maintain reliable service for the overall growth in the project area; and to comply with mandatory NERC Reliability Standards.
The company states that the expected in-service date for the project is May 1, 2021, for Part A, and in 2025 for Part B. The commission also said that the company states that the estimated cost of Part A is about $21.2m, including about $11.4m for transmission-related work and about $9.8m for substation-related work. The company stated that the estimated cost of Part B is about $9.1m, which includes $4.1m for transmission-related work and $5m for substation-related work.

Among other things, the commission said that any person or entity may participate as a respondent in the proceeding by filing a notice of participation by Feb. 28, 2020. Commission staff is to file with the commission clerk testimony and exhibits on the matter by March 13, 2020, and the company is to file any rebuttal testimony by March 31, 2020. The commission also said that any interested person may file written comments on the application with the commission clerk by April 7, 2020.
