After some smaller pilot projects, there is now a larger experiment. A subsidy of €5 million is being made available to support 472 smart chargers on charging plazas in 21 Dutch cities…

Of course, the whole capacity of a car’s battery won’t be available as a buffer for the grid. The owner/driver can set the amount of electricity the grid can borrow and what minimum charge the car should have. With only 472 cars connected to the grid, it is not the size of the reserve capacity that matters, but the speed with which it can react to fluctuations in the grid. When we have a hundred times as many smart public chargers, that’s when capacity becomes relevant.
