Fully charged recently did a video on the city of Utrecht in the Netherlands where I used to live: https://www.youtube.com/watch?v=L_BYDKz3_Jg https://www.youtube.com/watch?v=L_BYDKz3_Jg. They are implementing a plan there with vehicle to grid that basically boils down to having enough plugged in capacity at any time to be able to run the entire region for a while. The city of Utrecht has a few hundred thousand people and the wider region has closer to a million people.
Many people have the wrong ideas about the intentions of batteries on the grid. They are mostly used to deal with short term dips and peaks in demand and supply of power. A few thousand cars can provide a lot of power. Long term, we are talking millions of cars.
For reference, the Netherlands has about 8M cars on the road and a production capacity of about 35GW. If millions of those cars were plugged in they could easily keep the Netherlands powered for a few days even if all that production capacity was wiped out. That is of course not the goal and it would not be a good plan. But it's interesting that it could work.
A more likely scenario would be that those millions of cars would be used to deal with dips and peaks to the extent of a few hundred MW. Instead of switching on a gas peaker plant of e.g. 1GW for an hour or so, you'd instead end up draining less than a KWH per car over the course of an hour. The point of having that much capacity is not using all of it but being able to spread the load such that the load on each car is minimal. That minimizes the wear and tear on the battery and makes it easier for power companies to deal with even substantial demand peaks.
Additionally you can match local demand with local supply and not deal with efficiency losses associated with getting power from elsewhere; or worse importing it from abroad over long distance cables.
