Alstom won a contract worth about $86 million to supply new hydropower turbine-generator units to Hydro-Quebec’s La Romaine 3 powerhouse. The scope of the contract includes the supply of two 200 MW vertical Francis turbine-generator units complete with butterfly valves and regulation systems.
Alstom Grid, the company’s power transmission sector, is also contributing to the broader La Romaine hydroelectric complex through the supply of high voltage switchgear equipment — disconnect switches and circuit breakers. Alstom will manufacture the switchgear apparatus at its facility in La Prairie, Quebec.
The powerhouse is one of four new powerhouses that make up the 1,550 MW La Romaine hydroelectric complex, located north of the municipality of Havre-Saint-Pierre on the north shore of the St. Lawrence River. This contract was booked during first quarter of fiscal year 2013/2014.
Alstom will install and commission the equipment at the La Romaine 3 site.
The design of the turbines, generators and auxiliaries, and the project management will be led by the experienced team from Alstom’s North American hydro headquarters and factory located in Sorel-Tracy, Quebec. The design of the units will incorporate the health and safety standards required by the customer.
In March 2010, Alstom signed a contract for the supply of two 320 MW turbine-generator units for La Romaine 2. Alstom equipment at La Romaine 2 and 3, the largest of the complex’s four power houses, will account for two-thirds of the total 1,550 MW of electricity produced (5.3 TWh out of a total 8.0 TWh annually).
