Austria utility seeks bids to build 430-MW Reisseck 2 pumped-storage

Austria utility Verbund Austrian Hydro Power AG seeks bids for civil construction of the 430-MW Reisseck 2 pumped-storage project in Austria. Bids are due May 5.

Verbund announced plans in 2007 to build Reisseck 2 as an addition to the six-plant, 138.1-MW Reisseck/Kreuzeck hydroelectric complex in Upper Carinthia. (HydroWorld 10/9/07) The project represents an investment of about 215 million euros (US$287 million) and 3,000 person-years of employment.

The developer seeks bids for a water tunnel constructed by tunnel-boring machine, surge tank, penstocks, powerhouse and transformer caverns, approach roads, and related facilities.

Verbund said a special feature of Reisseck 2 is that existing storage and equalizing basins with a head of 580 meters will be used. A five-kilometer tunnel will connect the Reisseck annual storage reservoir and the 730-MW Malta Hauptstufe power plant.

The existing Grosser Muhldorfer See reservoir on the Reisseck lake plateau will be used as an upper reservoir in pump operation while the lower reservoirs will be the Gosskar and Galgenbichl reservoirs of the Malta power plant group, Malta Hauptstufe, 120-MW Malta Oberstufe, and 41-MW Malta Unterstufe.

The six plants in the Reisseck/Kreuzeck hydroelectric complex include 67.5-MW Reisseck annual storage, 23.2-MW Reisseck daily storage, 45-MW Kreuzeck daily storage, 1.6-MW Niklai, 600-kW Muhldorf, and 200-kW Steinfeld.

Bid documents, in German, may be obtained from the address below. Bids, in German, are due by noon May 5.
