The parent comment said overprovisioning and storage. With enough overprovisioning, you'd need storage for half a day at most (keep in mind that the parent thread was talking about pure solar with storage, not wind). The question on this sub-thread is: what would be the optimal (minimum cost) balance between overprovisioned solar and storage, and what would be the cost of that solution (the question was about 1GW, but it probably scales almost linearly), with similar reliability to pure nuclear (I'm assuming this pure nuclear scenario is overprovisioned too, since it has to deal with refueling pauses and the occasional electrical faults)?
(Of course, except for very small isolated networks, a real-life solution would not use only pure solar and storage; adding other things like wind to the mix would probably decrease the cost while keeping the same reliability.)
One cloudy January, and people would live in the dark for a month.
