The new year will bring some big changes at Greater Bridgeport Transit (GBT): the introduction of two new, all-electric
buses to the fleet.
GBT current runs 57 buses, 35 of them diesel-powered and
22 of them hybrids. The diesels get 3.2
mpg and the hybrids just 4.5 mpg, which means the busy transit agency must buy over
a half-million gallons of diesel fuel a year.
It’s a very busy transit agency carrying over 5 million
passengers a year (about 17,000 a day).
Fares have been steady since 2010:
$1.75 for 90 minutes on any route, $4 a day or $70 for a monthly
pass. And ten percent of their riders
are students, many of whom wouldn’t be able to go to school if it weren’t for
their bus passes.
Why electric buses?
“We want to reduce our use of fossil fuels and cut pollution,” says GBT General
Manager Doug Holcomb. “It’s just the right thing to do.” But finding the best electric bus hasn’t been
easy.
The transit agency needed to do a lot of modeling looking
at the length of their routes, the passenger loads and recharging times. While GBT’s average bus drives about 250
miles in its 16 hour workday, there was no electric bus which could reach that
range in local conditions.
Finally, they settled on a new 40 foot bus built by Proterra.
To be assembled in South Carolina and made with 75% US built parts, the
first two buses should arrive by this spring, with three more coming later in
the year. But they won’t be cheap.
Each electric bus, kitted out the way GBT wants them,
will cost $970,000. That compares to
$630,000 for a hybrid bus and $460,000 for a traditional diesel. The good news is that 80% of the cost will be
paid by a Federal grant with the other 20% coming from the state.
Aside from being much quieter, these new electric buses
will be an environmentalist’s delight.
Even factoring in the emissions from the additional utility generation
of electricity to charge these buses, just two electric buses in the GBTA fleet
will mean almost a half-million pounds less of CO2 in the environment.
The transit agency will also be buying less diesel fuel
and expects to reduce its maintenance costs given the simplicity of the motors. To handle the overnight charging the agency
has had to make a significant upgrade in its Cross Street garage. But that too is mostly being covered by
Federal funds.
What will riders see in the new electric buses? Comfy seats (but without padding to make
cleaning them easier), a security surveillance system, USB charging ports at
every seat and the all the ADA bells and whistles.
Even non-riders will benefit from the move to electric
buses as diesel fumes have
been linked to asthma and any reduction in that pollution is a positive.
CT Transit is also looking at electric buses for their
New Haven and Stamford systems. They
have an RFP on the street now and with any luck will start approving bids for
12 buses by March.
Fittingly, the federal funds
for these new CTtransit buses come from Connecticut's slice of the “Dieselgate” settlement with Volkswagen after
the German carmaker was caught cheating on the emissions standards of its
“clean diesel” cars." The state reportedly received $55.7 million and
planned to spend $7.5 million on upgrading public services fleets.
