The TUCO-to-Woodward 345-kV transmission line between Xcel Energy's TUCO Substation was energized when a connection was made with an Oklahoma line segment built by Oklahoma Gas and Electric (OG&E). Xcel Energy built the line from TUCO to just east of the Texas-Oklahoma boundary in Beckham County, Okla. The OG&E segment connects from the Beckham County site to Woodward, Okla. Total cost for Xcel Energy's portion of the TUCO line is approximately $205 million, shared among the member utilities of the Southwest Power Pool, the regional transmission organization overseeing grid reliability in portions of eight south-central states, including the Texas Panhandle-South Plains region and eastern New Mexico.
