GridLiance High Plains has begun construction of the Panhandle Reliability Project, which entails a new substation, new 115-kV transmission line, and upgrades to an existing GridLiance transmission line in Texas County, Okla., according to a March 4 statement posted on GridLiance’s website.
Vera Carley, director of communications of GridLiance, on March 5 told TransmissionHub that construction on the project began in February, and that the project’s total estimated cost is about $17m.
According to the statement, the project will improve service for Tri-County Electric Cooperative (TCEC) members in the region and ensure that the electric transmission system can serve new developments in the region.
The project includes building the new 15-mile, single-circuit line between the Powell Corner substation and the Four Corners community northwest of Guymon, Okla. The statement added that five miles of existing 69-kV transmission line from Four Corners to the new Panhandle substation will be rebuilt as a 69-kV and 115-kV, double-circuit transmission line; the new Panhandle substation is being built as a part of the project. The Powell Corner substation will be upgraded with the installation of a new bay to accommodate the new 115-kV line from the Panhandle substation, the statement noted.
“When we partnered with TCEC in 2016 and acquired their high-voltage transmission assets, we made a commitment to increase service reliability for its members,” Calvin Crowder, president and CEO of GridLiance, said in the statement. “While we have already completed other upgrades, the work we are undertaking now is the next step in our ongoing efforts to achieve that goal. The Panhandle Reliability Project will improve service for existing members and provide the transmission capacity necessary for new economic growth in the region.”
As noted in the statement, GridLiance in April 2016 acquired TCEC’s electric transmission assets, comprising about 410 miles of 69-kV and 115-kV transmission lines and the related substation infrastructure. An initial series of electric transmission system upgrades were completed on the GridLiance transmission system last year, the statement noted, adding that improvements included the construction of the Powell Corner and Hovey substations, as well as reconductoring and reinsulating nine miles of existing 69-kV transmission line to a 115-kV transmission line.
Zac Perkins, CEO of TCEC, said in the statement, in part, “The project will reduce the time of extended power outages, improving system reliability, and it will help power additional economic growth in the county.”
Construction of the transmission line and substation are scheduled to be completed in August, according to the statement.
