A ruling by the Missouri Supreme Court has revived the prospects of a 780-mile transmission project from Kansas to Indiana. The $2.3-billion Grain Belt Express Clean Line transmission project proposed by Houston-based Clean Line Energy is designed to move about 4,000 MW of wind power to population centers via a high-voltage direct-current line (HVDC). The project won approvals from regulators in Kansas, Illinois and Indiana, but stalled in August 2017 when the Missouri Public Service Commission (PSC) denied the project a certificate of convenience and need. The PSC said Grain Belt needed to secure approvals from each of the Missouri counties through which the line would pass. The state’s Supreme Court, however, said that PSC erred in its reading of state law. County approvals are only needed for distribution lines, not transmission lines, though county approvals are needed if the project affects publicly owned roads. The Supreme Court reversed the PSC’s decision and remanded the case to the commission.
