The energy revolution places new requirements on the transmission system in Europe. Within the next assets for long distance bulk power transmission need to be built. Root causes are wind power integra- tion in the north of Europe and solar power production in south. In the last consequence a new network layer will be built which is referred to as an overlay grid. With respect to the transmission requirements the DC grid option is supposed to be the most economic solution. This panel session will focus on activities carried out in Europe with respect to erect a new smart transmission level, to operate it and to integrate it into the existing infrastructure.
