Alstom has been awarded a contract worth approximately 50 million by utility Hydro-Québec to modernise the Robert-Bourassa generating facility in Canada, bringing a substantial increase to the plant's efficiency.
Consisting of 16 units with a total power generation capacity of 5,616 MW, Centrale Robert-Bourassa is the worlds largest underground generating station. The dam is located on the La Grande River in northern Quebec and one of the facilities of Hydro-Quebec's James Bay project. Together with the La Grande 2-A generating station, the two plants account for over 20% of Hydro-Quebec's installed capacity.
Under the terms of the contract, Alstom will design, manufacture and deliver four new 333 MW Francis turbine runners for units 1-4 of the dam, and carry out the complete refurbishment and modernisation of two turbine-generator groups. Alstom will also supply several new components (ring gate, distributor, servomotors and turbine shaft) for unit 1 of the power plant, while refurbishing some of the existing components for units 2 and 3, and replacing 16 electronic governor systems. Commissioning of the first upgraded unit is scheduled for autumn 2013.
The contract also includes an option for the supply of four more runners for units 4-8 and the refurbishment and modernization of six more turbine-generator units.
"Centrale Robert-Bourassa is strategically important for the province of Quebec and it is therefore a source of pride for Alstom to have been selected for this project. This contract further strengthens our long standing and excellent relationship with Hydro Quebec" said Jérôme Pécresse, President, Alstom Renewable Power, and Senior Vice-President Alstom Hydro.
