The proposed agency will provide advice to State authorities in order to assist them in evaluating all available financial options for infrastructure projects. It will be part of the NDFA's role to advise State authorities, such as Government Departments and agencies, as to the appropriate financing structure and to evaluate proposals submitted by the private sector. As well as providing centralised expertise on financial proposals, NDFA will assist in identifying optimal financing arrangements for major infrastructural priorities. In certain circumstances NDFA will be able to raise finance for PPP projects where this would be more cost effective than private funding. NDFA may also raise finance for conventionally procured capital projects where there are clear benefits offsetting any increased cost of agency funding over Exchequer funding.
