Zero-Emission Bus Fleets
charges are an increased cost for
energy assessed on the transit
agency when the transit agency
demands higher energy levels to
charge buses at peak load times
for durations as short as 15 minutes.
They can be very costly and
make a big impact on fuel costs
for the agency. By using an alternative
power supply such as
those listed here, the agency can
reduce its short-term demand on
the utility by deploying these
various micro-grid technologies.

such as extreme weather, when interconnected
with the grid. These
power-generating and storing
technologies are used to reduce
the demand from the grid so that
the transit agency can avoid demand
charges or time-of-use
charges that may be imposed by
their grid power utility. Demand
Affecting Change
at a Higher Level
Beyond project work, an important
way to make a positive impact
is through industry stewardship.
We both currently serve as industry
advisors to the Society of Automotive
Engineers (SAE), a globally
active association that since 1904,
has been responsible for developing
standards and best practices.
SAE has proven to be instrumental
in cases for the U.S. National
Highway Traffic Safety Administration
and its recommendations.
Last year, the organization
developed a universal charging
standard for overhead pantograph
charging that established
a common vehicle interface design.
SAE set the standard for this
vehicle interface so that operators
aren't beholden to a single manufacturer
or require adapters to
charge their fleets.
The work being done now in
California will continue to spread
to other parts of the United States.
And as the nation continues to
integrate zero-emissions technologies,
organizations like SAE are
already looking ahead. SAE may
next look to set a standard for
high power inductive (wireless)
charging.
