Fossil fueled power plants are cheap, quick to build, and has plenty of private companies that compete for the contracts. The cost per MWh has almost been cut in half for natural gas in the last 10 years, while nuclear is struggling to reduce costs (if at all). The cheapest possible energy gird currently available is to use wind as much as the weather allows it since it has currently the lowest cost per produced MWh, and natural gas for everything else. Solar is also starting to reach similar cost per MWh as natural gas when weather allows it. We might see a renewal in nuclear if natural gas (and other fossil fuels) were taxed to the point of being economical unattractive. Without that I don't expect something that cost twice as much to compete in a market with a fungible commodity.
