Transit Fleet Cost Model

Overview
This model allows for individual fleet analysis of baseline and scenario costs. The detailed input assumptions are in the Input tab and the baseline and scenario calculations with some key user inputs in the Main tab to allow for assessing fleet specific information. All cells that are shaded blue can be modified by the user without overwriting any calculations.
Bus costs and battery electric bus infrastructure costs are shown in section 1, and any other infrastructure costs, like shop chargers, hydrogen stations, inductive charging, are shown in section 2. Users who are interested in viewing the detailed calculation results or in the cash flow for any category the sheet can be expanded (and collapses) by clicking on the numbers 1 and 2at the top left.
Section 1 - Bus and Variable Infrastructure Costs
The model calculates life cycle costs for buses purchases in any year for each row in Section 1. This allows the user to input their existing fleet by entering the number of buses of each model year from model year 2000, and to project any number of new bus purchases in future years out to 2050. The model is set up to allow the user to input the total number of buses in the fleet and will model future purchases as a constant number of buses per year like other models. However, the user can also vary the number of future bus purchases in any year. The model is capable of evaluating multiple bus purchases of different types and from different manufacturers in any year (by using multiple rows for the same model year) if the data is added to the input sheet. Rows can be inserted or deleted as needed to model any combination of new purchases for more sophisticated scenarios by copying from an existing row and pasting the contents into a new row.
"All in" battery electric bus cost estimates include all associated charger and infrastructure costs except for shop chargers or supplemental equipment like inductive chargers to extend range.
Section 2 - Infrastructure Capital Costs
The model separately adds capital costs for infrastructure that is not directly associated with bus purchases like shop chargers, hydrogen station, fuel station upgrades, or site specific conditions, or supplemental chargers. These values need to be input by the user if applicable.
