German utility seeks to upgrade pump-turbines, equipment at 1,050-MW Markersbach pumped-storage

Vattenfall Europe Generation AG seeks bids for upgrade and repair of pump-turbines and other equipment of the 1,050-MW Markersbach pumped-storage project on Germany’s Mittweida River. Bids are due April 14.

Vattenfall Europe Generation, the German unit of Sweden-based Vattenfall AB, has performed numerous modifications to Markersbach since it was commissioned 30 years ago in Saxony State. Last year, it took bids to expand the upper and lower reservoirs of the project. In 2012, the utility took bids for concrete work at 11 hydro projects including Markersbach.

The utility now seeks bids for four lots to recondition and upgrade six 175-MW pump-turbines, perform on-site mechanical adjustments to pump-turbines and spherical valves, upgrade spherical valves, and upgrade cooling water and oil pipelines. The work is expected to require six years between November 2014 and December 2020.

Tender documents may be obtained from the address below. Bids, in German, are by 11:59 p.m. April 14 to Vattenfall Europe Business Service GmbH, Angebotseingangsstelle (Raum 4.0.113), Puschkinallee 52, 12435 Berlin, Germany.
