EDMOND — Pelco Products Inc. is poised for unprecedented growth thanks to “a classic sales story.” Subsidiary Pelco Structural LLC landed a contract earlier this year to design and build most of the support poles for an 800-mile transmission line project that will span Oklahoma and Arkansas. The Plains and Eastern Clean Line is intended to carry wind power from the Oklahoma Panhandle region to Tennessee and other southeastern states eager for renewable energy. Pelco — a leading manufacturer of traffic, ornamental and utility products — was eager to be a part of the $3.5 billion project after officials heard a Clean Line executive speak at the Tulsa Press Club in February. “We chased them,” Pelco Structural President Phil Albert said. Albert said Pelco officials talked to Clean Line about the project at a Washington, D.C., industry conference before spending three or four months detailing the company’s capabilities and its reputation for innovation, quality and service. He said Pelco is capable of delivering and installing its product as well as building and storing it, so the company can help cut project costs. “We’re building products for similar projects all across the country,” Albert said. Pelco secured its deal with Clean Line in June; it’s expected to create 100 new jobs and close to $300 million in work orders. “This project sets us on the national stage,” Albert said.
