WP 2 will identify the value of the various resources at local site and distribution network level, as well as the specific role that they can play, as part of determining/finding an optimal pathway to a renewable flexible energy system. The potential of those resources will be identified, while methods and tools will be developed, enabling the holistic utilization of the distributed and abundant flexibility, stemming from all energy carriers. Furthermore, optimal infrastructure expansion and operational strategies for Swiss local energy utilities and site operators will be proposed.
