 The electrification of public transport is becoming increasingly popular as it represents the first step towards the energy transition of the transportation sector. Public ownership and the strong influence of the public sector make tendering procedures the primary way to select the most efficient bus delivery options. These procedures are then used to compare and evaluate the differences in criteria used when selecting battery electric buses versus diesel buses in Poland. The results show that there is no significant difference in the criteria used in tenders between the two types of buses. Instead, the criteria and weights used in tenders are adapted to local conditions and operational requirements. Additionally, the paper examines how the criteria and weights used in tenders affect the total cost of ownership. It was found that the criteria and weights used in tenders do not take into account the advantages and disadvantages of both technologies, resulting in the same criteria being used regardless of the type of bus selected. Furthermore, the paper explores how the criteria and weights used in tenders can be adjusted to better reflect the advantages and disadvantages of each technology.
