New transformer in Upper Austria
In order to secure the long-term security of electricity supply in the Western Mühlviertel in Upper Austria as well as to improve the supply situation in the greater Linz area, TSCNET shareholder APG, the Austrian transmission system operator (TSO), is upgrading its substation near the Jochenstein Danube hydropower plant on the Austro-German border. These modernisation measures include a new 220/110kV transformer.
In September 2017, the 280-tonne transformer was delivered by ship across the Danube to Jochenstein. After five months of assembling and extensive functional tests under high-voltage, the state-of-the-art device was finally connected to the grid at the end of March 2018. The commissioning marks the completion of all construction work at the substation, with which APG ensures that green electricity from the Jochenstein hydropower plant continues to be safely fed into the Austrian transmission system. In total, APG invested €10m in the supply security of the region.
