Virginia regulators set deadline for comments on Dominion Energy Virginia’s 230-kV rebuild project

Dominion seeks an in-service date for the rebuild project of Dec. 31, 2022, subject to commission approval and outage scheduling, the commission said

The Virginia State Corporation Commission, in a March 3 order, said that interested persons may file with its clerk by April 14 written comments — as well as a written request for hearing — regarding Virginia Electric and Power’s d/b/a Dominion Energy Virginia estimated $11.1m rebuild project in Chesterfield, Va. (Case No. PUR-2020-00014)

As noted in the order, Dominion in late January filed with the commission an application for a certificate of public convenience and necessity to rebuild, entirely within existing right of way (ROW) or on company owned property in Chesterfield, Va., 3.2 miles of existing 230-kV Chesterfield-Locks Line #205 and Chesterfield-Poe Line #2003 from the company’s existing Chesterfield substation, located on Dominion’s Chesterfield power station site, to Structure #205/19A, #2003/25, which is located about 0.6 mile south of the company’s existing Tyler substation.

The rebuild project includes replacing 32 structures, currently ranging in height from 42 feet to 160 feet, with an average height of 109.4 feet. As proposed, the new structures for the rebuild project would range in height from 50 feet to 160 feet, with an average height of 111.7 feet.

The commission added that according to Dominion, the lines that make up the rebuild project predominantly share double-circuit “COR-TEN” steel lattice towers that were built in 1962. Those towers have been identified for rebuild based on the company’s assessment consistent with its planning criteria, the commission said, adding that Dominion stated that it retained Quanta Technology to evaluate the condition of its towers. According to Dominion, the 2016 Quanta Report confirms the need to rebuild the “COR-TEN” section of Lines #205 and #2003.

Dominion seeks an in-service date for the rebuild project of Dec. 31, 2022, subject to commission approval and outage scheduling, the commission added. Dominion estimates the rebuild project to cost about $11.1m, which includes about $10.8m for transmission-related work and about $0.3m for substation-related work (2019 dollars).

The commission also said that its staff is to file with the clerk by May 1 a report containing its findings and recommendations on the matter. The company may file with the clerk by May 15 any response in rebuttal to the staff report and any comments filed by interested persons in the proceeding, the commission said.
