Another (Russian) nuclear plant that is under construction is expected to produce more expensive MWh's than most of the competing energy sources. In practice, the some foolish buyers of Fennovoima nuclear power plant's energy have been committing into buying energy at a price of 50€/ MWh, while the other energy sources are clearly cheaper than that. Its quite likely that the Fennovoima's nuclear power plant never be producing any energy at a competitive price.
On the other hand, the price of solar keeps sinking 50% in a decade and it's already enough competitive with the prices of other energy sources. Development of high capacity solar energy storage solutions is much more needed than the new nuclear power plants.
