Consultation 3

Baseline

What scenario should be considered as baseline for the SmartNet analysis? Should we stick to the two options below, or would you suggest another one?
a) Option 1: Only resources connected to transmission level can provide ancillary services.
b) Option 2: Coordination scheme A, in which resources connected to distribution level can provide ancillary services (when certain preconditions are met). This is the current situation in Denmark and in Spain, and it will also probably be the case in Italy in the near future

Q.1

If option 1 is selected, can we ensure that the resources connected to transmission network will be enough to provide all the ancillary services required by the system? If not, what actions should be taken? How would the congestions at distribution level be solved?

Q.2

If option 2 is selected, some costs/benefits may not be adequately addressed and not easily compared. For instance, let’s assume that the costs of implementing a control system for coordination scheme A is 100 and the costs of implementing a control system for coordination scheme B is 130. Since these control systems are not scalable, it is not immediate to state that passing from A to B would cost 30 but, in principle, it can be any value between 30 and 130. Do you have experience with this kind of issues?
