The City of Garland, Texas (Garland), d/b/a Garland Power & Light (GP&L) on May 31 filed with the Public Utility Commission of Texas an application to amend its certificate of convenience and necessity for the Nevill Road to Greasewood Single-Circuit 345-kV Transmission Line in Pecos County, Texas.
The proposed line, which would be built on steel monopole structures, would extend from the proposed Nevill Road switch, located southwest of, and adjacent to, Garland’s existing Bakersfield to North McCamey 345-kV transmission line, about one mile south of Nevill Road, and the proposed Greasewood substation, located two miles north-northeast of the Owego Road and U.S. Highway 67 intersection. Garland added that the line would require a 125-foot-wide right of way (ROW) and be about 10.3 miles long.
The project is necessary to interconnect Concho Bluff’s solar generation facility Garland said, adding that it has been requested to interconnect at Concho Bluff’s to-be-built Greasewood substation at 345 kV.
The new Nevill Road 345-kV switch would be owned by Garland, while the new Greasewood substation would be owned by the generator, Concho Bluff.
Garland also noted that it is proposing one consensus route for the project because the three landowners directly affected by that route have provided their written agreement to the route. In addition, the consensus route is a forward-progressing and relatively direct path from the proposed Greasewood substation to the proposed Nevill Road switch that meets applicable criteria of the Public Utility Regulatory Act (PURA) and commission rules.
The area traversed by the line is located in the High Plains Physiographic Province of Texas, which is divided into – from north to south – the Central High Plains, the Canadian Breaks, and the Southern High Plains. Garland added that the study area is predominately rangeland/shrubland and has experienced a moderate degree of alteration due to extensive oil and gas development and production, agricultural uses, transportation corridors, as well as existing electric distribution and transmission lines.
No habitable structure is located within 500 feet of the consensus route’s centerline. Garland also said that no park or recreational area is crossed by the consensus route centerline and that no park or recreation park is located within 1,000 feet of the centerline.
Garland noted that the estimated total cost for the transmission facilities portion of the project is about $11.6m, and about $14.9m for the substation facilities portion of the project.
According to the estimated schedule, ROW and land acquisition would begin in August and be completed in January 2020; engineering and design would begin in September and be completed in March 2020; material and equipment procurement would begin in January 2020 and be completed in July 2020; and construction of facilities would begin in August 2020 and be completed in December 2020, which is also when the facilities would be energized.
