That's only partly the reason. Many of these older plants were closed because of the new mercury regulations which will reduce the mercury deposition rates here in the US anywhere from 1to 10% raising the average IQ 2/1000 of one point.
If the EPA mandated that you put thousands of dollars of pollution control on that old car you're better off just scrapping it even if it runs perfectly. That's what happened with those plants.
Assuming the new CO2 regulations are finalized which should happen in the coming months new coal plants to replace them won't be built for many years to come if ever, kind of hard to argue about what is more economical when regulations over CO2 will need to be addressed with technology that doesn't exist in a production environment.
