Keeping the Lights On


In the past, Tri-County Electric Cooperative (TCEC) members in the Oklahoma Panhandle regularly contended with severe weather that disrupted electric transmission service in the region for days and weeks. To keep the lights on and reduce the number and severity of power outages, GridLiance completed a series of upgrades to transmission and related facilities, including substations that dated back to the 1950s. The three-year project increased the reliability of the regional grid and improved transmission service levels for TCEC’s members. The work created more than $440 million of economic benefits in the region, according to a study conducted by Oklahoma Panhandle State University, and enables load growth in the Panhandle.
