You need to cover the "once every 20 years there's a modest shortfall and we can predict it 2-3 days out" which we are at now.
And that's because the variable sources of power discussed here don't make up much of the power supply. Crank it up to a much larger percent and you will have problems more often.
A lot of this stuff is just off-loading costs onto electricity consumers. For example, all those businesses who can't just afford to be down for hours or days just because the "once every 20 years modest shortfall" happens again and again will need beefed up backup generators and power storage - stuff the electricity provider no longer provides.
