KW Wassen Lot 4.1b Revision of Turbine Machine 1

This tender concerns the revision of Machine Turbine 1 (MG1) at the Wassen Power Plant (KWW). The Wassen Power Plant, located on the Reuss river in the municipality of Wassen, is a crucial component of the Reuss cascade, alongside the Göschenen and Amsteg power plants. This cascade collectively generates 40% of the Swiss Federal Railways' (CFF) traction current, with the KWW contributing an average annual production of 290 GWh. Therefore, the KWW plays a vital role in supplying traction current along the north-south axis.

Lot WV 4.1b specifically focuses on the overhaul of the Francis turbine MG1. This turbine has the following technical specifications: power output (P) ranging from 20.7 to 26.8 MW, a net head (Hn) between 230.7 and 275.0 meters, and a flow rate (Q) of 10.5 to 11.4 m³/s. Potential temporal overlaps with ongoing works in other lots may necessitate work interruptions during the construction phase. Bidders should be aware of this possibility when planning their execution strategy.

This is a consulting contract in the energy and power, architecture and engineering and construction and civil works sectors, with a focus on Power Generation, Mechanical Engineering and Construction Supervision. Located in Switzerland, Europe, this opportunity is open to firms and consortiums.
