JEFFERSON CITY, Mo. — A proposal for a high-voltage power line carrying wind energy across the Midwest might now move forward after the Missouri Supreme Court ruled that regulators wrongly rejected it.

The ruling that was handed down Tuesday means that Missouri must re-evaluate whether Clean Line Energy Partners deserve approval for a $2.3 billion project that would build one of the longest electric transmission lines in the U.S.

Clean Line has been working on the so-called Grain Belt Express power line since 2010 but hasn’t been able to start construction because of regulatory hurdles.

The line would run from wind farms in western Kansas across Missouri and Illinois before hooking into a power grid here in Vigo County that will then serve the eastern U.S.
