to the cost of operations performed with diesel or CNG buses); and it can be
ensured for the propulsion battery as well which is the main element of the
sustainable operational performance during the specified period.

Evaluation and Conclusions

Today, accelerating the transition from conventional systems to electric
systems in buses used in rubber-wheeled public transportation systems offers
an important opportunity to reduce emissions from transportation and combat
climate change. However, according to data for the public transportation sector
excluding China, it is stated that although more than 100,000 new buses are
purchased worldwide annually, only 13% of them are electric buses (Hummel,
2018). According to the basic scenarios based in many studies, the amount of
greenhouse gas emissions is estimated to be 1,175 Mt CO in Türkiye by 2030.

Electric buses to be used in public transportation systems that are expected
to be the locomotives especially for the electric vehicle industry in Türkiye, are
considered as a good starting point for the reduction of emissions.
With the business model based on the innovative electric bus procurement
approaches to be introduced in this study, an alternative approach for the
relevant audiences has been presented within the framework of the Public
Procurement Law of Türkiye. In accordance with the current public procurement
applications, both the obligation to use the Turkish Lira and the limited periods
contained in the contracts bring various challenges in the supply of electric
buses for local governments within the framework of the envisaged business
models. An innovative and sustainable business purchasing model is presented
with the “Public Transportation Operational Performance” contract, which is
introduced specifically for public transportation systems within the scope of
ICP model. This model allows the procurement of the electric buses in line
with the legislation and practices in force. Technical Specifications is important
for the application of the main tendering documents. In this context, the base
of non-price factors It is suggested that electric bus procurement tenders are
held. By starting the tenders with small scale pilot projects; It is recommended
to provide feedback on possible malfunctions and/or incompatibilities
specific to the public transportation operator/authority that may occur. It is
considered as an alternative procurement method where the above points,
which are emphasized as useful and important, can be implemented within
the framework of the transportation policies to be put forward before the
upcoming elections for local governments.
