This service contract for local public transport aims to improve the quality and quantity of transport offered, to cope with the expected increase in passengers during the jubilee event. ATAC requested that Roma Capitale supply 1,057 new buses to be added to the fleet and to remove about 960 outdated, highly polluting, and inefficient vehicles during the 2023-2026 period. ATAC played an active role in implementing these investments, using funding that covered 90% of the cost for new buses, while the remaining 10% was covered by self-financing (except for the 411 electric buses fully funded by PNRR Funds). In this context, this specific intervention involved the purchase of 244 new 12-metre methane buses, with a total cost of 75.9 million euros (net of VAT). To meet additional needs, another 78 buses were purchased from different funding sources. ATAC, as the implementing body, adopted an industrial strategy with a single tender process for the acquisition of new buses and the entire maintenance service.
