You are delusional if you think renewables and storage will be the same reliability as base load plants like nuclear, gas, coal

Renewables and storage wouldn't drop gigawatts off the grid in an instant. They'd be massively redundant and distributed. That's how you get reliability.

No way any current place is building that kind of oversupply and redundancy

"No one is doing it therefore it is impossible" is a remarkable argument, especially from someone trying to argue nuclear can replace fossil fuels.
