To solve some of these challenges that arise with the implemenation of the new legislation on electricity grids in Germany, different working groups have been established. First of all, there is an overarching communication group at federal level, which consists of all four TSOs plus the regulator/permitting authority. In addition, groups for specific projects have been formed, comprising of state governments, the regulator/permitting authority and the project promoter. In these groups, project plans are being discussed and possible difficulties addressed. While TSOs and the permitting authority agree that informal measures of information and participation have to permanently accompany the formal procedure, there are different views about the timing and the goal of these measures. The groups allow for good opportunities to align these different perspectives. They meet approximately every third month.
