The report presents the methodology and major results of the third phase of the FLEXNET project. This phase is focused on elaborating a societal framework for the trade-off between grid expansion investments and deployment of flexibility for congestion management. Given the increasing demand for flexibility as shown in the second phase of the FLEXNET project, the number of situations with a high and simultaneous peak demand for electricity transport at specific locations and points in time will increase. Grid operators can resolve the resulting grid congestion either by grid expansion investments or deployment of flexibility for congestion management. Since this choice affects not only network operators but also producers, consumers, and other actors, there is a need for a societal framework. Dependent on the size of avoided grid expansion investments and the available information to determine effects, the report shows that an indices cost-benefit analysis (CBA) or indicative CBA would be most appropriate. Next, the relevant CBA steps are applied to the issue at hand, which includes carrying out a problem analysis, determination of baseline and project alternatives, and identification of relevant effects. The next step, quantification of these effects, depends on the expected size of the effect, required time and efforts, and whether quantification would contribute to societal support for the deployment of flexibility. The feasibility of deployment of flexibility for congestion management purposes requires abolishment of the Dutch rule that limits the duration of deployment of congestion management until network reinforcements are ready. Besides, implementation of the societal framework in legislation and/or network regulation would boost its uniform application by network operators. Finally, the report concludes that further research is desirable for obtaining better insights in the societal value of flexibility in specific situations by applying the developed framework.
