TULSA, Okla. (AP) — A project that would develop wind farms and build a $3.5 billion transmission line from far western Oklahoma into Tennessee has cleared a regulatory hurdle that allows a company to being lining up customers.

The Plains and Eastern Clean Line project won approval Wednesday from the Federal Energy Regulatory Commission to strike deals with utilities to purchase up to 75 percent of the 7,000 megawatts of electricity that’ll be distributed through the line.
