Who is financing this project?

At this stage, the financing of the studies has been defined, but that of the construction of the extension has not yet been defined.

• The preliminary studies up to the public inquiry, amounting to €8.82 million, are financed 70% by the Île-de-France Region and 30% by the State via the Société des grands projets.
• The financing of the detailed design studies and the construction of the extension remains to be defined, if the project goes ahead and obtains, if necessary, a declaration of public utility. For this type of transport project, financing is generally organised within the framework of State-Region Plan Contracts (CPER), to which local authorities, in particular Departments, Territorial Public Establishments and Municipalities, can also contribute. The funders and the distribution among them are gradually specified, by means of financing agreements corresponding to the different stages of the project.
• The 12 additional trains needed to operate the extension would be 100% financed by Île-de-France Mobilités.

There is therefore no financing plan for the extension at this stage. This will have to be defined with the various partners if the project continues.
