Norways. With no upgrades. The Norwegian Water Resources and Energy Directorate has a study showing the details. That’s assuming that most people charge at night. But that’s already happening. Setting up a modern EV to charge based on electricity prices is dead simple. And since electricity is more expensive when the load on the grid is highest, people wanting to charge their cars in the cheapest way will necessarily charge in a way that doesn’t overload the grid. Norway does have a pretty strong grid. It has primarily used electricity for heating, with some wood but not much gas. People are transitioning to heat pumps and improving insulation as well so the load on the grid from heating is actually going down too. Other countries may eventually need some grid upgrades. But how is that an insurmountable issue? The grid has been upgraded in response to increased demands many times before. The same battery tech going into EVs is helping improve and stabilise the grid, and helping some people reduce their energy consumption from the grid to near zero with solar+battery storage. So seems like EVs help contribute to the exact kind of R&D needed to take some of the added load off the grid.
