Even though four of its five members stated unequivocally that a proposed wind energy transmission line would be in the public interest, the Missouri Public Service Commission on Wednesday said it could not grant Clean Line Energy Partners a permit for development of the Grain Belt Express. The commission said it was constrained by a recent state appeals court ruling in a different transmission case. A lawyer representing clean-energy interests said that another appeal is a near-certainty. Mark Lawlor, Clean Line’s vice president for development, wasn’t quite as definite.“I think it’s sort of placed the burden on Clean Line to go ask the courts to sort this out,” he said. “Because of this legal quagmire, the project can’t move forward. It’s a broken system. It’s a problem for Missouri.”
