Substation Ernsthofen

The Ernsthofen substation, which was first commissioned in 1941, is one of two network node substations within the northern operating region with 380/220/110-kV outdoor switching stations. Its maintenance area covers substations in Ernsthofen, Kronstorf, Ybbs Field, Hausruck, Pyhrn, Bergern, Sattledt, Wegscheid, Leonding, Pichling, Abwinden, Ottensheim, Wallsee, Großraming, Rosenau and Klaus in addition to power lines in the northern region. The substation acts as a coupling point that joins the distribution grids in Upper Austria and Lower Austria. The 380-kV, 220-kV and 110-kV outdoor switching stations are connected via grid coupling transformers. A phase-shifting transformer is used to control load flows.

The substation is also the base for an overhead line team whose role is to manage the high-voltage overhead lines in the region, ensure that they are operating properly as well as to carry out maintenance work and remedy any faults.
