The company has already started building the integrated gasification combined cycle (IGCC) power plant in Kemper County, about 30 miles north of Meridian.

The Sierra Club opposed the project before the PSC; however, the PSC entered an order in favor of the power company. The Harrison County Chancery Court later affirmed the commission’s order. The Sierra Club appealed.

The state’s high court, in a unanimous decision, said the PSC did not provide evidence to support its decision allowing the company to start charging ratepayers. The order was remanded to the Commission for further proceedings.”
