At the same time, the condominium takes benefits for the load shifting of Family 1 since it increases its payoff to EUR 2081 (+4.7%). \begin{table}

Table 9: Yearly revenue of each stakeholder of the configuration for Scenario A-EC, considering different levels of load shifting from user Family 1. As already mentioned, all the users are driven to shift their load to increase (or simply, not reduce) their pay-off. The effect of the load shifting provided at the same time by all the users has been tested. The resulting payoffs are reported in Table 10 and in Figure 2b. On average, the increment of the revenue of each single passive member is 41.7%. Nonetheless, the effect is strongly different among the users. In particular, the average increment of the young couples is equal to 129.2%, while for the offices there is an average reduction of 10.5%. Similarly, to what already observed in the previous case, the improvement of the performances of some users has a slightly negative effect on the revenues for the users that are not improving (or improving less). In other words, in the base case, the offices are awarded for their relative importance in the configuration. Indeed, without any load shifting they are the only users with relevant load during the hour of PV production, and they are fundamental to obtain the incentive. When all the users shift their profiles, offices lose this relative importance, and their revenues are reduced. From the perspective of the condominium, the load shifting is extremely beneficial, and its revenues increase by 22.3%. Figure 2: Impact of load shifting on the yearly revenues for each member of the configuration in Scenario A-EC: (**a**) only Family 1 is performing load shifting; (**b**) all the passive members are performing load shifting. It is important to point out that the load shifting has a positive result both for the overall revenues and for the payoff allocated to the condominium.
