Oncor seeks approval for 138-kV project in Winkler County, Texas

Oncor Electric Delivery Company on Aug. 16 filed with the Public Utility Commission (PUC) of Texas a standard application for a certificate of convenience and necessity for the proposed Balding Point of Delivery (POD) 138-kV Transmission Line Project.

The proposed single-circuit line would be built on double-circuit capable structures between the proposed Balding POD and the existing Oncor Wink-Loving 138-kV transmission line segment of the Wink-Culberson line in Winkler County, Texas. The proposed Balding POD would be located about 4.5 miles west of Wink, Texas, adjacent to State Highway 302 just west of the Targa Midstream Services LLC Wildcat facilities in Winkler County, the company added.

The existing Oncor Wink-Loving 138-kV transmission line is about 2.5 miles south of the proposed Balding POD, the company noted, adding that Targa is involved in the right of way (ROW) acquisition for the proposed project.

Oncor and Targa have signed a letter agreement for Oncor to provide transmission service to Targa’s new substation located in Winkler County, Oncor said, noting that Targa is installing new oil and gas processing facilities in the area and plans to build, own, and operate its own substation in Winkler County. In order to provide transmission facilities necessary to interconnect Targa’s new substation facility to the electric grid, Oncor said that it proposes to build, own, and operate the 138-kV line extension tapping the existing Wink-Culberson 138-kV Line, in the Wink-Loving 138-kV line segment.

The proposed project includes modifications at the tap point of Oncor’s existing Wink-Loving 138-kV line and at the POD location, Oncor said, noting that that work may include dead-end structures, transformers, grading, and fences, among other things.

The estimated total cost for the transmission facilities portion of the project is $3m, and $135,000 for the substation facilities portion, the company said.

The length of the proposed line project route is about 2.5 miles, the company said.

All of the necessary ROW for the project is acquired or in the approval process, Oncor said, noting that 75% of land is acquired by easement, while 25% of land will be obtained through the University of Texas Permanent University Fund lands (UT Lands) ROW Process. That is a ministerial process where a prescribed fee is paid to have a land lease granted, the company said.

The project area is situated in a relatively remote portion of Winkler County, and no incorporated cities, unincorporated towns, or communities are within the project area. Oncor also said that almost the entirety of the study area consists of rural and undeveloped land used primarily for livestock grazing or oil and gas production. The topography of the study area is gently rolling with primarily desert grass-shrub vegetation, the company said, adding that residential and commercial development is absent within the project area.

Among other things, the company said that according to the estimated schedule, ROW and land acquisition began in June and is to be completed in November; engineering and design began in June and is to be completed in December; material and equipment procurement is to be completed in February 2018; and construction of facilities is to begin in December and be completed in March 2018, which is also when the facilities would be energized.
