Alstom, a French maker of power-generation and grid equipment, signed an agreement with RusHydro, the country's biggest renewable energy company, to upgrade nine dams on the Kuban River, French Prime Minister Francois Fillon said. The "significant" deal will be concluded during Fillon's two-day trip to Russia that began Thursday, the prime minister said in an interview in Rossiiskaya Gazeta, the government's newspaper of record. Alstom and RusHydro also signed an agreement on production of hydroelectric equipment in Bashkiria, the French company said in a statement distributed to reporters Thursday. The company reached an agreement to upgrade power stations belonging to Mosenergo, as well. Alstom's Russian joint venture, Alstom-Atomenergomash, agreed with Rosatom to produce nuclear turbines.
