摘要

With the commissioning of the 380-kV high voltage transmission line between the substations Tauern and St. Peter in the spring of 2025, the decommissioning and dismantling of the previous connection between these two grid nodes began—the 65-year-old 220-kV line. Quietly, throughout 2025, the last section of this 65-year-old, originally 143-km-long, 220 kV power transmission route between the switchyards Salzburg and Tauern will also disappear. At the time of its construction, this line was rightly recognized as a pioneering achievement in transmission line engineering for several reasons:

– First domestic 220 kV ring closure in Austria: Kaprun—St. Peter—Ernsthofen—Weißenbach—Kaprun

– First high-alpine transmission line in Austria’s extra-high voltage grid, with sections over 2000 meters above sea level

– Only 18 months of construction time until completion and commissioning in October 1960

– The majority of materials and services were provided by Austrian companies
