The Virginia State Corporation Commission (SCC), in a July 10 order, said that a local public hearing is to be convened on Sept. 14 in Woodbridge, Va., to receive testimony on Virginia Electric and Power’s d/b/a Dominion Energy Virginia’s application for approval and for a certificate of public convenience and necessity to build and operate electric transmission facilities in Prince William County, Va.
The company proposes to rebuild, entirely within an existing right of way (ROW) and company-owned property, about 8.5 miles of existing 115-kV transmission lines, Possum Point-Smoketown Line #18 and Possum Point-Smoketown Line #145, located between the existing 115-kV switchyard at the company’s Possum Point Power Station site and the Northern Virginia Electric Cooperative (NOVEC) Smoketown Delivery Point (DP), the SCC noted.
The company proposes to utilize 230-kV design on all but the first 0.7-mile segment originating from the 115-kV switchyard at the Possum Point Station site, which would be rebuilt to 115-kV design. The SCC also noted that while the company proposes to build the lines to be capable of operating at 230 kV, the company states that operation of the lines would continue at 115 kV until such time as needed to serve the Northern Virginia Load Area.
According to the company, the SCC said, the proposed rebuild project is necessary so that the company can maintain and improve reliable electric service to customers served by Lines #18 and #145, which have been identified as nearing their end of life, consistent with the company’s transmission planning criteria.
The company has noted that the lines were originally built between 1948 and 1954 on single wooden H-frames and wooden three-pole H-frame structures, and that the company has determined that it is no longer cost-effective to continue to repair or replace individual components.
Among other things, the SCC also noted that the company anticipates an in-service date for the proposed rebuild project of December 2019, and that the estimated cost of the rebuild project consists of about $18.8m for transmission line work, and about $124,000 for station work.
The SCC said that regulatory staff is to file testimony and exhibits by Sept. 28, and that the company is to file any rebuttal testimony and exhibits that it expects to offer by Oct. 12. A public evidentiary hearing on the application is to be convened on Nov. 2 in the SCC’s second floor courtroom in Richmond, Va., to receive the testimony of public witnesses and the evidence of the company, any respondents, and staff, the SCC said.
