French hydro operator seeks study, design of replacement turbines for 272-MW Mareges hydro project

French hydropower operator Societe Hydro-Electrique du Midi (SHEM) seeks bids to study and design four replacement turbine runners for the 272-MW Mareges hydroelectric project on France’s Dordogne River. Bids are due September 3.

SHEM, a unit of ENGIE, operates 49 hydroelectric plants totaling 773 MW under concession on rivers or dams. It seeks bids by August 24 to supply electro-mechanical equipment including a turbine-generator for rehabilitation of the Castela hydroelectric project.

SHEM issued a similar Mareges solicitation in March to supply four replacement runners. Mareges, completed in 1935 in Correze Department, features four 37.5-MW turbine-generators plus a 122-MW unit added in the adjoining St. Pierre plant in 1988.

SHEM now says it is considering replacement of the four 37.5-MW units and seeks firms that can perform studies and calculations to improve the flow profile and manufacture vertical Francis turbine runners. The work is to be carried out from August 2015 to October 2018.

Solicitation documents may be obtained until 5 p.m. September 1 from the address below.

Bids, in French, are due by 5 p.m. September 3. For information, contact Camille Frazza Lignieres, SHEM Engie, 1 Rue Louis Renault, 31133 Balma, France; (33) 561171598; E-mail:; Internet:
