I don't think so, because Peabody has been battling the Navajo Nation and enviro's for some time over it's coal mining and tremendous use of water to transport it's coal to Edison's plant. The coal mine has been in the cross hairs for years & years and was, I think, going to end up shut down anyway. Edison, having no readily available coal for their plant, was going to have to shut down.
The enviro's got a two-fer out of this.
Maybe so, I have no specific info on Mojave at hand, but I daily keep up with the generation buisness. But I know a station that large with a nearby available coal supply would not let scrubbers come between them and staying operational. If there are other killers to the deal, it may not be feasible. Many times fuel transportation cost is the largest expense to a coal-fired plant.
Maybe the Utilities should burn "enviros" instead of coal! Now that would be a "two fer one" I could get behind!
