A reserved zone serves to keep an area free for future lines. In a reserved zone, no projects that could interfere with the construction of a new line may be undertaken for a maximum of eight years. The national grid company (Swissgrid) can apply to the Swiss Federal Office of Energy for reserved zones.
A reserved zone can impose restrictions on landowners. For this reason, reserved zones form part of the cadastre of public-law restrictions on landownership (PLR Cadastre).
This dataset contains all the reserved zones currently applicable. It also contains all requested reserved zones if the canton in question uses the PLR Cadastre for the official publication of plans.
