A public evidentiary hearing on the May 15 application for a certificate of public convenience and necessity filed by Virginia Electric and Power d/b/a Dominion Energy Virginia is scheduled for Sept. 11 at the Virginia State Corporation Commission’s second floor courtroom in Richmond, Va., the commission said in a June 1 order.
As noted in the order, the company is seeking approval to rebuild, entirely within an existing right of way (ROW), an approximately 8.2-mile section of the existing 11-mile, 230-kV transmission Lines #211 and #228, which run from the company’s existing Chesterfield substation in Chesterfield County to the company’s existing Hopewell substation in the City of Hopewell.
The company is also seeking approval to rebuild two structures on Lines #211 and #228 near the Chesterfield substation on company owned property, as well as to complete minor equipment replacements at the Chesterfield and Hopewell substations.
The commission added that according to the company, the rebuild project is necessary to replace aging infrastructure that is at the end of its service life in order to comply with the company’s mandatory transmission planning criteria, thereby enabling the company to maintain the overall long-term reliability of its transmission system and the generating capabilities of the system.
The company anticipates that the rebuild project could be in service by Dec. 31, 2020, subject to commission approval and outage scheduling. The commission also said that the estimated cost of the rebuild project is about $26.4m – that is, about $25.8m for transmission line work, and about $0.6m for substation work.
According to the company’s application, Lines #211 and #228 run 11 miles from the Chesterfield substation to the Hopewell substation, and about 8.2 miles of those 11 miles were built in 1969 on double-circuit “COR-TEN” weathering steel towers, which have been identified for rebuild, based on the company’s assessment in accordance with mandatory transmission planning criteria.
The company said that it proposes replacing 46 230-kV, double-circuit, weathering steel lattice towers and one double-circuit, 230-kV weathering steel pole (Structure #29) supporting Lines #211 and #228 – for a total of 47 structures – with 33 230-kV, double-circuit, weathering steel poles for the tangent suspension structures, and 14 230-kV, double-circuit, weathering steel, two-pole, double deadend structures for the line angles – for a total of 47 structures.
The length of the existing ROW to be used for the rebuild project is about 8.2 miles long, and since the existing ROW is adequate to build the proposed project, no new ROW is necessary, the company said.
Written comments on the application are to be filed with the commission by Aug. 10, the commission said in its order, adding that its staff is to file testimony by Aug. 17.
