Hydro operator Societe de Forces Motrices de Chancy-Pougny SA (SFMCP) seeks bids for civil works and electro-mechanical equipment for fish passage and a 500-kW micro-hydro plant utilizing fish attraction flows at the 49-MW Chancy-Pougny hydroelectric project. Bids are due March 13.

SFMCP, which is jointly owned by Services Industriels de Geneve of Switzerland and Compagnie Nationale du Rhone (CNR) of France, recently upgraded Chancy-Pougny to 49 MW from 37 MW, on the Rhone River between Switzerland and France.

The fish passage includes 60 successive concrete basins over 230 meters on the right bank of the Rhone. The hydro plant is to utilize fish passage attraction flows of 4.3 cubic meters per second and a drop of 10 to 12 meters.

The hydro plant is to include two butterfly valves, two or three cofferdams, two intakes, three screens, a Kaplan or propeller-type turbine of 450 to 500 kW, an asynchronous generator, transformer, controls, and a crane.
