They could transition to a combined cycle plant if they wanted to increase efficiency. I'm obviously not an expert, just like 99% of people here. If you look at the basic sentiment here it is that this seems like a fake solution to the problem of coal power plants and I somewhat agree. I think that it would help to know that they are at least attempting to move away from coal towards nuclear or renewable sources. It seems like there are a lot of solutions that could be pursued.
