Developers of a proposed $2 billion transmission line say they are returning their attention to Missouri after Illinois regulators approved the multistate project.

The Columbia Daily Tribune reports Clean Line Energy will try again to persuade Missouri regulators to approve the 780-mile Grain Belt Express transmission line that would carry wind-generated electricity from Kansas through Missouri and Illinois to Indiana.

Illinois officials gave their approval Thursday. Missouri's Public Service Commission voted in July to deny Clean Line's application for a certificate of need and public necessity, a step necessary to carry wind energy from the plains across Missouri. The commission said developers didn't provide evidence the project would benefit Missouri.

Mark Lawlor with the Grain Belt project said officials haven't decided whether to file a new case with the commission or pursue the project through federal energy regulations.
