Repower has played a significant role in increasing cross-border capacity between northern and southern Europe by building the international Bernina Line (380 kV/220 kV), commissioned in 2005 and transferred to the Swiss national grid operator Swissgrid at the beginning of 2013.
In October 2009, Repower joined forces with Edison and the municipality of Tirano to inaugurate the first A/C merchant line in Europe.
