Bids sought for renewal of Forstsee pressure pipeline

KELAG-Kärntner Elektrizitäts-Aktiengesellschaft, a leading multi-utility in Austria, invites bids by 30 March for the renewal of the steel pressure pipeline serving the 2.4 MW Forstsee pumped-storage plant in Techelsberg am Wörther See in the southernmost state of Carinthia.

The contracted works, which are scheduled to begin in October 2020 for completion by the end of May 2021, covers the replacement of the pipeline, over a length of approximately 350 m, which supplies the powerhouse, located 20 km west of Klagenfurt, directly on the shore of Lake Wörthersee, between Pörtschach and Velden, according to a tender notice published on the EU’s procurement website on 10 March.

The renewal of the pipeline is part of a complete rehabilitation of the Forstsee powerplant, which was commissioned in 1925, and is the oldest storage plant in Carinthia. The rehabilitation programme will also include renovation of the Pelton twin turbine and the intake structure, to increase the efficiency of the plant. It currently produces around 3 GWh of peak electricity per year, harnessing a head of around 160 m. The Forstsee reservoir, with a storage capacity of 4.7 x 106 m³, acts as the upper reservoir.
