Southwestern
Electric
Power
Company (SWEPCO) is building a new
345,000-volt transmission line between
Valliant, OK, and Texarkana, Texas.
During the construction of the line near
Texarkana, construction crews have
used helicopters to perform work on
the transmission line. Two aerial-service
contractors,
Erickson
and
Winco,
performed the work to assemble and
place transmission poles, transport
workers, and pull wire between the
structures.
This method of construction is expected
to help reduce impact to the land, and
minimize damage to property.
Construction of the 77-mile line began in
Oklahoma in early 2014 and is expected
to be complete in both Oklahoma and
Texas in late 2016.
The project was ordered by the Southwest
Power Pool (SPP), the regional transmission
organization responsible for overseeing
the electric transmission grid in parts of
Oklahoma and Texas to address regional
reliability issues.
