For years I've been supposing that more BEV's plugged into the grid each night will provide higher base load for our nukes to throttle up. Perhaps that will go toward (non-solar) renewables now, even better. There's, what... 100 million cars in the USA, average age 11 years? Seems we could be a decade away from half of them being EV's, which if smartly managed for overnight charging, could really bring down our peak to average grid load ratio. That's before even discussing selling capacity back to the grid, simply managing charging times and rates across a large fleet by incentivizing off-peak usage.
What's your perspective on this?
Google says there are more like 275M light vehicles in the US, not 100M.
Currently, most projections are for EVs to reach 50% light vehicle penetration for new sales in the US around 2028. But the age of vehicles being as you said about a decade, it will take another decade plus for half of the vehicle fleet to be EVs... more like 2040, under an optimistic scenario.
Comparing that time course to the current decarbonization of the US power grid... EVs show up to the party a decade too late, and their used batteries show up two decades too late. We can expect the CO2 emissions from the grid to fall by 50% from 2005 levels in the early 2030s (and still be dropping fast). While EVs will drop fleet emissions by vehicles by 50% in the early 2040s. The grid also started switching a decade sooner than the EV rollout, so that makes sense.
The helpful thing about EVs for decarbonization is that they will drive down the prices of ALL storage batteries. Storage isn't really a big problem (i.e. to avoid large amounts of curtailment) until renewable energy reaches about 20% of the energy supply... so its just becoming an issue nowadays in CA (solar) and TX (solar and wind) and the prairie states (wind). So that means that mass adoption of EVs (while still only ~10% of sales) is leading to massive investment in battery plants and mining operations, which will spin out the cheap batteries for renewable storage that we will need to get to higher renewable penetration in 8-10 years.
IOW, everything is going just according to the long term decarbonization Master Plans I got from AOC and Soros.

You are asking about better nuke utilization and vehicle to grid (V2G) and or vehicle to load V2L....
I dunno. In 1978 many imagined that by 2023 we would all be living in passive solar homes with trombe walls and giant boxes of rocks in the basement (or earthships), to drive our heating oil consumption down by 50% in the winter. How did that pan out? It didn't bc it was too complicated, and doesn't work in most places, and it impossible ($$$) to retrofit into existing construction.
Similarly, many places won't have a big problem with seasonal renewable storage (like the West, which has great solar and wind in the winter, and the South for solar). I think the Northeast, which is kinda boned for renewables in the winter, will go pretty big for offshore wind and heat pumps in new construction. I think New England (and the northern tier of US states) will just bring up the rear on most of this green stuff (while Boston folks will make a big show of not being behind). They'll be running gas plants and nat gas equipment in their homes longer than the rest of the country does, and lag EV adoption a good bit too. Just like how they are all still rocking heating oil (aka liquid coal) up there and spending $0.33/kWh for electricity and driving low mpg non-hybrid Subies.
Bottom line is that the Northeast looks a lot more like the EU in terms of population density, infrastructure, income and climate than the rest of the country does. And it shows now. So if the EU does a lot of V2G or V2L (or air to water heat pumps) the NorthEast will probably get into it too. The EU/UK are already big into offshore wind, while New England lags due to our nutty maritime flag laws and the Kennedys. While the rest of the country will just go for a much simpler and cheaper utility-based renewable system, on a shorter timeline, following the lead of California or Texas (which are basically doing the same things).
