Societe d’Energie de la Baie James, a unit of Canadian utility Hydro-Quebec, has awarded a contract to Alstom Hydro to equip the 138-MW Sarcelle hydroelectric plant, part of Hydro-Quebec’s Eastmain 1A/Rupert Diversion hydroelectric complex in northern Quebec.
Alstom Hydro, a joint venture of Alstom and Bouygues, received a C$130 million (US$132.5 million) contract to supply three 46-MW bulb turbine-generators with governors and downstream gates. The plant is expected to begin operation in 2011.
ï¿½Even though we will install at the Sarcelle power plant this type of bulb-type units for the first time in Quebec, we have the required expertise to carry out the work as the company has already installed many such units elsewhere in the world,ï¿½ Alstom Hydro President Claude Lambert said.
The project involves construction of two powerhouses ï¿½- Sarcelle and 768-MW Eastmain 1A -ï¿½ and partial diversion of the Rupert River to the Eastmain 1 reservoir. (HNN 9/13/07) Water diverted from the river will be run through turbines at 480-MW Eastmain 1, now under construction, and the Eastmain 1A powerhouse. It also will be directed through existing powerhouses in the La Grande complex: 5,328-MW Robert-Bourassa, 1,998-MW La Grande 2A, and 1,368-MW La Grande 1.
