The European Investment Bank has, over the past 8 years, been supporting the Ministry of Infrastructure and Transport and OSY in the progressive expansion of the Athens bus fleet with electric vehicles. This transition is increasing electricity demand and warrants a need for a long-term investment plan for energy supply and management in bus depots. In response, the European Investment Bank Advisory Team (EIB Advisory) will work with the Ministry of Infrastructure and Transport and OSY S.A. to develop a programme that will ensure that energy needs and charging infrastructure will be delivered to support ongoing investment in electric buses in Athens.
