The first to collapse will be nuclear reactors, because they cannot deal with such low prices. Only the cheaper energies can. Even is you are half the year at a prize of 0, if the other half compensates you are fine. That's what drives eolic and solar, as they think "OK, in that scenario we would break even in 12 years instead of 6. Not bad either". Gas can adjust to produce only in the positive half of the year, and also "we would break even in 20 years instead of 10". Meanwhile, nuclear reactors and specially new nuclear projects, have to take in consideration than half of the time they will be producing at zero, and the other half barely covers the costs (mainly amortization). They are in a "at those prices we would never break even" scenario. The key point is that the sources in the margin (i.e. with less profit margin) are the ones to collapse first, while the most efficient ones keep going on with less profits, but profits nonetheless.
