The Netherlands is often seen as a leader in electric mobility. Could you imagine delivering control power with EVs in the German market too?
Elias De Keyser: The provision of control energy with mobile assets is somewhat more complex than with stationary assets, especially if they are connected to the low voltage grid. Several questions need to be addressed, such as "in which balancing group is the control energy provided?", “what is the impact on the household supplier?”, and "how can prequalification processes be designed in a way that works for everyone?”. In Germany, these questions need to be clarified first. Projects like the one with Jedlix and TenneT are very valuable because we learn how these questions can be solved best. It also builds confidence among other European grid operators that decentralized flexibility can reliably deliver ancillary services.
What was your biggest learning from the pilot project?
Elias De Keyser: We have been delivering aFRR for several years in countries like Germany, but we didn’t have any experience with electric cars. This pilot project was an opportunity to push our boundaries and experiment with the flexibility potential from an EV-fleet. We also developed a unique approach to integrate the EVs in our pool, whereby Jedlix acts as a sub-aggregator. The integration with their systems provides a blueprint for other integrations of fleets of, for example, home energy storage systems and domestic electric boilers. This will come in handy in the near future, for example in our collaboration with Sonnen.
Nick Hubbers: Obviously, we assumed EV drivers would be willing to provide control energy. Still, it was very reassuring for us to see, that they really are committed. From a technical point of view, we learned that it is challenging but doable to provide aFRR. However, for a sustainable solution and participation in the regular market, there are still some administrative barriers to overcome. We understood that the role of an independent aggregator is new to the established system and still needs to find its place. For now, we are very happy to have achieved our main objective and shown that electric vehicles can deliver aFRR successfully.
