For the transit and refuse fleets, each hostler required 4 additional vehicles
to pay himself off in 7 years. Because both of these numbers are less than a
hostler can handle, these fleets should never limit their number of CNG buses
based on what their current staff can handle. It seems to be a sound decision to
increase staff to accommodate as many CNG vehicles as possible.
Each hostler for a school fleet required 55 additional buses. Therefore, it
would only make sense to hire an additional hostler if he can service 55 buses
or more.
What if I Open My Refueling Station to the Public?
Opening a refueling station to the public changes the project economics in
a number of ways that are listed below. There is too much variability to model
all of these factors in one scenario, but each factor was modeled independently
in response to questions earlier in the report.
1)
Many project grants are tied to the station opening to the public. This
is the same as if the upfront station cost was reduced, as modeled for
this question: "What happens if the price of my station changes?"
2)
Excess capacity may be added to the station to accommodate public
vehicles refueling at the same time as the primary fleet. Other
equipment such as card readers may also be necessary. These both
add to the upfront cost, which is also modeled in the "What happens if
the price of my station changes?" section.
3)
The refueling window might need to be expanded to accommodate
public vehicles. Increased refueling windows were modeled when
answering this question: "What happens as I have more or less time to
refuel?"
4)
The number of attendants must be increased to facilitate sales to the
general public. This increase is also modeled in the "What if I have to
hire a hostler or attendant?" section.
5)
Opening to the public will likely increase wear and tear on station
equipment. This increase is explored under this question: "What if my
maintenance costs increase or decrease?"
6)
A profit can be made on each GGE of CNG sold to the public. The
profit on each gallon affects the firm's finances the same as if the
price of diesel went up so the firm saved more money on each gallon
of CNG used. This impact is very significant, as shown in the "What
will a change in diesel prices do to my payback period?" section.
