So, rather than blow the grid, the regulators will call the nuclear plant and tell it to go off line. But to do that, it has to shut down so it won't be up again for three days. A week later it happens again, and so it goes that spring and the next fall and all of a sudden, the cost of operation of the reactor just went through the roof. The nuclear industry whines about base load and all that but shortly the economics take over and that plant is decommissioned because it just isn't flexible enough to work in a renewables dominated grid.
At this point, or a little sooner, it is realized that what we really need is energy storage, fast in to handle over production, and slow out as a reservoir to handle night time. Any thoughts on what that technology would look like would be appreciated.
