Caisse des Dépôts and Vauban Infrastructure, two investment firms, completed the acquisition of Coriance, a company that builds, develops and operates urban heating and cooling networks supplied locally and mainly by renewable energies and recovery, from Igneo Infrastructure Partners, an infrastructure firm. Financial terms were not disclosed. "Our equity stake in Coriance, a major player in heat and cold networks in France, allows the Caisse des Dépôts to support the State's ambition to achieve carbon neutrality and to fully meet our strategic objectives: accelerate ecological transformation and support national energy sovereignty, strengthen social and territorial cohesion,” Eric Lombard, CDC General Director.
