Distributed energy resources (DER) are becoming more and more appealing in terms of costs and technology, so a massive diffusion is expected in the near future. On one side, DER can provide important flexibility services to DSOs as well as to TSOs, enabling them to operate the electricity system in a more cost-efficient way, closer to operational infrastructure limits: the use of flexibility can offer alternatives to the traditional approach to investments in new network infrastructures to face growth and peak demand. In particular, it would be possible to overcome the current «fit and forget» approach, which often allows connections of new generators only after proper network reinforcement.  On the other hand, DER will demand new services to the network, due to new customers attitudes and behaviours triggered by e-mobility, digitalization, decentralised energy management systems. A high digitalization of the network is required, to enable these new services and to continue guaranteeing quality and security of supply.In this scenario, distribution networks and their operators will play a new challenging role: the network operators will procure balancing, congestion management and ancillary services from assets connected to the network, both at transmission and at distribution level, based on a close cooperation among them. This will enable more efficient and effective network management and optimization, and the integration of increasing shares of renewables, too. A strategic role will be played by digitalization of network infrastructures, to properly manage flexibility and use/enable DER services, and by adequate cybersecurity protection and resilience levels.
