Question juridique clé
Whether switchgear and related facilities at the interface of the transmission grid belong to the transmission network under Art. 2 Abs. 2 StromVV.
Solution extraite
Such facilities belong to the transmission network when they serve as the connection of a power plant or downstream grid level to the transmission grid; the ordinance is compatible with the statutory definition.
Motifs extraits
Art. 2 Abs. 2 lit. b StromVV must be read in light of Art. 4 Abs. 1 lit. h StromVG and the ordinance preamble. The law covers the transmission network plus necessary ancillary installations; interface switchgear is part of it, while isolated switchgear between lower grid levels is not.
