It has taken two years of intense work and NOK 145m to build the new facility. The facility has been in operation since June, and now delivers 150 GWh of energy in the form of steam to the nearby aluminum company Rio Tinto Alcan (RTA), equivalent to reducing nearly 40,000 tons of greenhouse gas emissions.
Mr. Helge Aasen, Elkem CEO and Mr. Jean Villeneuve, Senior Vice-President, Elkem AS – Foundry Products Division participated at the ceremony. Also present were distinguished guests, Mr. Stéphane Bédard – Minister responsible for Government Administration and Chair of the Treasury Board, Mr. Jean Tremblay – Mayor of Ville de Saguenay and Mr. Jean-François Nadeau – Plant Manager for Rio Tinto.
The project was realized in collaboration with the Elkem Engineering department, local engineering firms, local contractors and by the Chicoutimi plant management. The facility was built during normal furnace operations, and the Elkem Chicoutimi plant employees made sure that safety was in focus at all times.
The water used in energy recovery runs in a closed loop. The steam is generated by off-gas from a 29 MW furnace and then transported to Rio Tinto Alcan via a 3 km pipeline. RTA uses the heat in a Bayer process for recovering alumina from bauxite. The water is then transported back again to the steam generator at the Chicoutimi plant.
The Ministry of Natural Resources and Wildlife has through its Agency for energy efficiency given financial support to Elkem for this project.
