DETAILS OF CONTRIBUTIONS in 2021 In million
Work has continued at a steady pace despite the Covid-19 situation. In 2021, payment appropriations for Société du Grand Paris
amounted to 3.6 billion (stable compared with 2020),
matching the record level of expenditure in 2020.
The 2.5 billion spent on the Lines under its direct control
and 1 billion on Line 14 (not under its direct control) are a
clear indication of work on all Grand Paris Express lines
ramping up in 2021.
Société du Grand Paris has invested 24.9 billion in the
Grand Paris Express since 2010 and has contributed 3
billion to several modernisation projects for existing metro
and RER lines as part of its transport mobilisation plan.
Société du Grand Paris continued its support for several
modernisation projects on the existing metro and RER
networks with 364.6 million in contributions as part of
financing agreements with the Île-de-France region, the
government, local authorities and transport operators.
