Can you tell us what kind of control or planning does an EV charging operator need to tap into that revenue stream reliably? Well, first of all, these different services, they have different technical requirements. So the first thing is you need to cover the technical requirements. These are both on the level of the charger, for example, technical requirements on the charger. But also, for example, let's take AFR, for example. It's about a deviation from a baseline. So you need to be able to demonstrate what your baseline behavior was. And then you have deviation. And then you are, let's say, remunerated based on that deviation. So these are a couple of things with respect to metering, data handling that you need to cover. And so these are more like technical requirements. But an important part is, of course, the management problem. The optimization problem is, again, so these different services, they work with very specific mechanism. And you need both to optimize towards the remuneration scheme of that service, but also deal with the constraints and the uncertainty of that driver. You still need to fulfill the driver requirements for his next trip, let's say. And that's, again, why use case is so important.
