Look at Texas- they only fall apart 1-2 days per year, but that's enough that it's a crisis every time. How confident are we that our hydro dams can sustain us in the worst case every year or decade?
I think to achieve it, we would need to see financial incentives, direct or indirect, to have everyone buying up power batteries for their homes, reducing the variable load. Maybe price incentives like nearly free electricity at night and extra costs during the day, etc.
