Maybe way back then. Now other fuel sources are cheaper, cleaner, and easier to use. Power companies don’t want to screw with coal anymore. Why would a power company want to mess around with a fuel that must be mined, trucked, rail transported, and then dispose of hazardous waste? Natural gas turbines get fuel delivered by pipelines, can be fired up and turned off instantaneously, and burn clean with no plant cleanup or waste to dispose of. And cost less overall. Solar farms, once installed feed energy directly to the grid, supplementing the gas turbine produced energy. There is zero reason to mess around with a fuel that’s both dirty and more expensive.
