Virginia regulators: Public evidentiary hearing on proposed 138-kV line to convene in June

The Virginia State Corporation Commission, in a Jan. 30 order, said that a public evidentiary hearing on Appalachian Power Company’s application for approval to build, own, operate, and maintain the Glendale Area Improvements 138-kV Transmission Project will convene on June 18 in the commission’s second floor courtroom in Richmond, Va.

As noted in the order, Appalachian Power is seeking approval from the commission to build and operate:

  • The new two-mile Wolf Glade 138-kV Extension transmission line on a 100-foot right of way (ROW) between a tap point on the company’s existing Jubal Early-Piper’s Gap transmission line and a new Wolf Glade 138-kV substation to be located in the City of Galax, about 0.5 mile northeast of the company’s existing Cliffview substation
  • The new Wolf Glade substation
  • A 0.5-mile relocation and extension of the Cliffview 69-kV Tap transmission line
  • An addition of a 138/69-kV transformer and other improvements at the Jubal Early substation
  • A new 138-kV line termination, associated equipment, and a control house expansion at the Huffman substation

As proposed by the company, following completion of the project, the existing Cliffview substation, about 0.2 mile of the Cliffview 69-kV Tap, and about 14 miles of the double-circuit 88-kV – operated at 69 kV – transmission line between the Byllesby and Wythe substations would be retired.

The commission added that according to the company, the proposed project would maintain reliability for its customers in the City of Galax, as well as parts of Carroll and Grayson counties in light of thermal and voltage violations of applicable transmission planning criteria. To address those violations, the company asserts that the proposed project would need to be in service by December 2021.

The commission added that according to Appalachian Power the proposed project is the more efficient, cost-effective, and comprehensive long-term electrical solution, with fewer environmental impacts, when compared to alternatives to the proposed project.

Appalachian Power estimates the conceptual cost of the proposed project to be $38m, consisting of $13m for transmission line-related costs and $25m for substation-related costs.

The commission added that the proposed two-mile, double-circuit, 138-kV line and 0.5-mile, double-circuit, 69-kV line comprising the project would require new ROW easements. The proposed route for the proposed two-mile line crosses Carroll County and the City of Galax, while the proposed route for the proposed 0.5-mile line would be located solely within the City of Galax. Appalachian Power represents that some new third-party access road easements may also be required for the proposed project. The commission added that the company further asserts that the proposed Wolf Glade substation would be located on a 16.7-acre parcel, which the company has purchased.

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 April 2. Also, by May 7, each respondent may file with the commission clerk – and serve on regulatory staff, the company, and all other respondents – any testimony and exhibits by which the respondent expects to establish it case. The commission added that staff is to file with the clerk a report containing its findings and recommendations on the matter by May 21. The company may file with the clerk any response in rebuttal to the staff report and any comments filed in the proceeding by June 4. The commission added that any interested person may file written comments on the application with the commission clerk by June 11.
