"A first-of-its-kind 'clean coal' power plant that utility owner Southern Co. spent years constructing in Mississippi may end up burning no coal at all -- and instead just run like a natural gas generator.

After years of delays and billions of dollars in cost overruns, Mississippi regulators on Wednesday called on Southern to work up a deal that would have the Kemper plant, now estimated to cost about $7.5 billion, fueled only by gas. The state Public Service Commission said in a statement that it’s looking for a solution that eliminates the risk to ratepayers “for unproven technology,” which involved converting coal into gas that could then be used to generate electricity -- all while capturing emissions.

Settling for gas only at Southern’s Kemper plant threatens to undermine the business rationale for the kind of clean-coal technology the Trump administration has hailed as a way to save jobs at mines. It would mark the end of a very costly venture that has company investors demanding pay cuts for executives. The utility owner is also grappling with its long-delayed, over-budget Vogtle nuclear project in Georgia."
