Kassø-Tjele high-voltage transmission line
High-voltage transmission line in Denmark / From Wikipedia, the free encyclopedia
The Kassø-Tjele high-voltage transmission line is a 400 kV high-voltage transmission line in Denmark from Transformer Station Kassø by Kassø west of Aabenraa to HVDC converter station Tjele by Foulum east of Viborg. Along the way, it passes the Coupling Station Revsing by Vejen and Station Askær by Brande. The transmission line is a total of 174 km long and is operated by Energinet, which describes it as the backbone of the Jutland-Funen electricity transmission network.[1]

In the period 2012-2014, the transmission line was upgraded from a single-system line with a capacity of 1.150 MW for a two-system line with a capacity of 2 x 1.800 MW or a total of 3.600 MW.[2] The upgraded transmission line was put into operation on November 28, 2014.[3]
The main purpose of the expansion of the transmission line was to be able to exchange surplus production of electricity with other countries, i.a. to and from Norway via the Skagerrak connections. In particular, the expansion of electricity production from wind turbines made it necessary to be able to transport electricity from wind turbines when there is a lot of wind and the production of wind turbine power is high, in order to be able to utilize the energy.[4]
