We wish to actively participate in the energy transition by building "carbon neutral" public technical infrastructures for small and medium-sized municipalities financed by "operational leasing PPP" without impacting the balance of municipal accounts. Innergia has developed an innovative economic mechanism enabling it to offer local public authorities their energy transition through the realisation of their sustainable technical infrastructure as a total enterprise, i.e. turnkey construction as a general contractor, as well as full financing through "PPP operational leasing" without impacting on municipal finances and using institutional investors as a source of financing.
