Demand response is basically - please don't use power because we don't have enough or because it's expensive. That's not an appealing option.
Smart grid management is good but it'll take years to reach good condition - you need to expand/upgrade transmission and distribution systems with proper equipment.
Germany has it's own path that's more or less stable for a long time- coal+gas firming, tons of ren and major transmission expenses, to the point govt will start subsidizing them
It's a strange double standard. As is the building of expensive pumped hydro storage for use with nuclear.
THE UK gets 30% of its electricity from wind and another 5% from solar; Denmark gets 70% from renewables, mostly wind. Iowa gets 65% of its electricity from renewables, mostly wind; California, whose economy is larger than that of most countries, gets 38%, mainly from solar.
But some lobbyists are trying to kill momentum, especially those who see nuclear as a silver bullet. It is not.
what you described with demand response is equivalent of rationing- use power when weather is good because otherwise you'll not afford it
Don't confuse transmission needed for 1GW of nuclear vs 10GW of solar with 10% cf and more redispatching requirements
Take cars, for instance. When someone buys an EV rather than ICE, do you think the EV consumes the same amount of energy than the ICE car?

Sure, what do you think that needs to be done when there is a limited resource such as electricity? Yes, produce more, but until then, what should the grid do?

It is two different models, one is centralized (nuclear) and the other is distributed (solar). The planning is essentially different.
Yes, you need vastly more transmission for a distributed ren grid. Both for deployment and for avoiding curtailment
Solar panels in rooftops can decrease the saturation of the grid, so more transmission is not necessarily needed.
