Constellium signed an agreement with French energy provider Dalkia and the City of Issoire, France, to launch the Energ’Iss heating network project. Through the project, heat recovered from Constellium’s local furnaces for aluminum production will be converted by Dalkia to provide heat and hot water to buildings and homes in Issoire.
“We are very proud of our contribution to this ambitious project and to be able to provide solutions that support our community and the environment,” explained Stéphane Corre, director of the Constellium plant in Issoire. “CO2 reduction is a priority for Constellium and for our communities, and such projects demonstrate the benefits of public-private collaboration.”
To implement the heat recovery system, Constellium installed a system to collect residual heat at the exit of its furnaces. Dalkia is responsible for installing a heat exchanger to supply a new distribution network that will provide heat and hot water to some 40 buildings and homes in the city.
“We are proud of the trust placed in us by the City of Issoire and Constellium for this sustainable heating network project, which will achieve a rarely equalled 90% rate of renewable and recovered energy,” said Jérôme Aguesse, Dalkia’s regional director for the Center-East region of France. “Through its dedicated company Energ’Iss, Dalkia has been able to propose innovative technical solutions for developing green energy in Issoire. The success of this project will help make Issoire a national benchmark for sustainable development.”
With this new heating network, the Issoire is demonstrating its commitment to renewable energy by reducing CO2 emissions, while using a more economical solution than traditional heating networks. “The City of Issoire is committed to the energy transition thanks to this technologically innovative and environmentally friendly partnership,” said Bertrand Barraud, mayor of Issoire. “This project strengthens the close ties between our city and its economic fabric and contributes to the influence of the entire region. Our heating network, through the energy savings it generates, is a message of hope for future generations.”
Work on the Energ’Iss heating network project is scheduled to begin in November 2021, with the new utility service to be commissioned in the fall of 2022.
