Electric Transmission Texas (ETT), in a May 25 application filed with the Public Utility Commission of Texas, said that it is proposing to design and build a new 345-kV transmission line in Foard County, Texas, to interconnect a new wind facility.
The proposed line would be built as a single-circuit line on double-circuit-capable tubular steel monopole structures, ETT said, adding that the line would extend from the ETT Edith Clarke 345-kV station to the new Foard City substation, which will be owned by the generator, Foard City Wind, LLC.
Discussing the need for the project, ETT noted that Foard City Wind has requested ETT to interconnect at its to-be-built Foard City substation at 345 kV to provide interconnection service to its planned 350-MW plant capacity comprised of 140 GE 2.5-MW wind turbines.
The number of miles of right of way (ROW) for the proposed project is about 2.6 miles, ETT said, noting that the number of miles of circuit would be about 2.7 miles.
The line would require a nominal 150-foot-wide ROW, ETT said, adding that the typical structure for the project would be about 140 feet to 195 feet in height.
The specific area of the project is used for farming and some ranching, ETT said. That is the primary reason that self-supporting tubular steel monopole structures were selected for the project since they do provide a reduced structure footprint, ETT noted. The reduced footprint of the monopole structure would ease the ability to access the easement in a manner to reduce the impact to farming operation for maintenance of the area around the structure, as well as provide the ability of the farmer to utilize more of the property, according to ETT.
According to the estimated schedule, if the project is approved, ROW and land acquisition would begin in June and be completed in December; material and equipment procurement would begin in August and be completed in December; and construction of the facilities would begin in January 2019, and be completed in May 2019, which is when the facilities would be energized.
The transmission facilities would cost about $7.5m, and the substation facilities would cost about $5.3m, ETT said.
Among other things, ETT said that no habitable structures are located within 500 feet of the “consensus route,” and no park or recreation area is located within 1,000 feet of that route’s centerline.
