The Public Utility Commission of Texas, in an April final order, approved Golden Spread Electric Cooperative’s application concerning a request to convert a 69-kV line from private to public use in Concho County, Texas.
As noted in the order, Golden Spread in April 2018 filed an application with the commission to amend its certificate of convenience and necessity (CCN) to reflect the acquisition of the Colorado River Municipal Water District’s existing 69-kV line and conversion of the line from private to public use. No physical conversion is necessary to convert the existing line from private to public use, and no new construction or alteration of the existing line is required, the commission said.
As TransmissionHub reported, Golden Spread said in its April 2018 application that it and its member, Coleman County Electric Cooperative (Coleman Electric), received a request from Enterprise Products Partners L.P., to provide transmission voltage (69 kV) retail electric service to Enterprise’s new pipeline pumping station (the Millersview pump station), which will be located in Coleman Electric’s singly certificated retail service area in Concho County.
Coleman Electric asked that Golden Spread supply wholesale power to Coleman Electric at a delivery point near a substation being built by Enterprise for its Millersview pump station, Golden Spread said, noting that CRMWD owns and operates a 12.6-mile, private 69-kV transmission line that serves CRMWD’s O.H. Ivie Reservoir water pumping facilities, (the existing line), located about 0.85 miles away from the Enterprise project site.
Golden Spread said that in this proceeding, it seeks to amend its CCN to add the existing line and convert it to public use, so that Golden Spread may operate the line as a public utility facility in ERCOT.
Enterprise is building the Midland to Sealy (M2S) segment of its larger Midland to ECHO crude oil pipeline system for the transportation of crude oil and condensate from the prolific Midland basin to markets along the Texas Gulf Coast, Golden Spread said.
Enterprise determined the best location for a pipeline pump station for the M2S segment, also known as the Millersview pump station, is off FM 1929 (Ray Stoker Jr. Hwy) near CRMWD’s Lake Ivie pumping facilities, Golden Spread said. At the Millersview pump station, Enterprise has built a substation designed to convert 69-kV power to a lower operating voltage, Golden Spread said, adding that Enterprise will own and operate that substation.
The commission noted in its April 4 order that Golden Spread’s purchase of the existing line from the district is not part of the application. Golden Spread’s purchase of the existing line does not involve the transfer of any certificated rights or facilities currently regulated by the commission and involves consideration of less than $10m.
The commission also noted that Golden Spread will purchase the existing line from the district for $3.5m, which includes all existing transmission assets, easements, and land rights.
The commission said that in connection with the conversion of the existing line, Golden Spread proposes to build a new 0.85-mile, 69-kV line extension to a new substation built, owned, and operated by Enterprise Products Partners at its Millersview pump station. Neither the new line extension nor the Enterprise substation is part of the application. The estimated cost of the new line extension is $913,000.
The commission also said that the area traversed by the existing line is typically undeveloped flat rural land interrupted by periodic creekbeds. The property is used primarily for grazing livestock and, to a lesser extent, for producing cultivated crops. The commission also said that the area includes scattered single-family residences and agricultural outbuildings.
The existing line originates at the terminals of an existing switch point along AEP Texas Inc.’s Ballinger-to-Eden 69-kV transmission line, which is part of the ERCOT transmission system, located seven miles southeast of Paint Rock, Texas, and one mile east of U.S. Route 83. The existing line extends in a northeasterly direction to the point where insulators attach to an existing dead-end tower in the district’s existing substation at the O.H. Ivie Reservoir, the commission added.
The existing line is about 12.6 miles long and consists of a single circuit. The commission added that after the existing line becomes public, Golden Spread will have the capability and contractual duty to provide wholesale transmission service to Coleman Electric and other potential wholesale customers from the existing line at 69 kV.
Among other things, the commission said that Golden Spread must inspect the existing line and make any necessary repairs before placing the existing line into public use.
