From the German perspective, the penetration of electric vehicles already started a couple of years ago. The one thing we learned there, which I also mentioned, was the infrastructure to charge these vehicles and the electric supply. Just to give you an idea, if on a given street, everybody had an electric car and charged it at the same time, the transformer would not be enough.
We want to make this charging infrastructure for buses intelligent. The answer is laying there. How can we optimize, and how can we ensure we are not charging at peak times, which is already a stress factor for the grid?
You mentioned vehicle-to-grid charging back into the system. What is required is the optimization of the overall system. We are running pilots in Germany where we are looking into these optimizations and how to do that. In fact, we are also piloting in Atlantic Canada together with Nova Scotia Power and New Brunswick Power. That is work that is still ahead of us, and we need regulatory reforms to make that happen. Without that, it would be challenging.
