The playing field in the energy market is not a level one. Most power generation plants have been built in the past due to either a subsidy of money or a state sanctioned monopoly. Due to these factors, the cost of traditional power plants is lower than it probably would be. So unfortunately the only way that any of these companies are going to actually proceed is if the playing field is "leveled" through additional subsidies. Since our current electric infrastructure is not a real market place of any sort, this is not necessarily a bad thing, as in the end, we the taxpayer/consumer pay for it all anyways. The only time this non market would be bad is if the technology that were being pushed actually had no benefit to those who are paying for it. It's kind of like the roads, there are few roads built today that are not paid for with a government subsidy which is taken from the taxes on gasoline.
