Austria utility seeks tunnel rehab at 9.58-MW Opponitz

Vienna utility Wien Energie GmbH seeks bids for tunnel rehab at the 9.58-MW Opponitz hydroelectric project on Austria’s Ybbs River. Bids are due November 13.

Wien Energie plans 30 million euros (US$38.1 million) in economic and environmental improvements to the 88-year-old small hydro project. Work is to include a fish ladder and a new weir at Gostling that will increase the amount of water used by the Opponitz hydro plant. An additional turbine-generator is to be added to the project, whose installed capacity is to increase to 12.5 MW.

Wien Energie took bids in 2012 for hydraulic steel, earthworks, and a turbine-generator for Opponitz. The utility also recruited potential partners in 2012 to develop the 300-MW Pfaffenboden pumped-storage project in Austria.

Wien Energie now seeks bids to renovate the tunnel at Opponitz including use of a relining procedure. The work is to be performed between February and June 2014.

Tender information may be obtained from the Wien Energie Internet site under http://wstw.vergabeportal.at/DetailContent.aspx?portal=wstw&atxtnr=20894. Bids, in German, are due by 1 p.m. November 13.
