POWER SUPPLY
ABB points to two real world
examples of WESS in operation.
Southeastern Pennsylvania Transportation Authority (SEPTA) began its first WESS project in 2012
and, following two subsequent
phases, decided to roll out the
technology across its entire system.
In a white paper on the project, a SEPTA WESS substation
capturing 1.2MWh of energy per
day, can deliver electricity at a cost
of around $0.06/kWh over a 15year period or $0.09/kWh over 30
years, the higher figure accounting
for additional maintenance costs.
For comparison, SEPTA's grid delivered power is $.095/kWh.
New York Metropolitan Transportation Authority (MTA) will
launch a pilot project in 2019 with
ABB and Viridity that will be funded by New York State Energy Research and Development Author-

ity. The pilot aims to use the stored
energy to do peak shaving during
periods when rates are highest.

Environmental
considerations

Alstom notes the emergence of
environmentally-friendly
innovations that also address the
energy efficiency of rail systems.
The company says that the transportation sector in most countries
is the second largest producer of
environment damaging emissions,
which is why environmental considerations among rail stakeholders have been on the rise.
"Such innovations are also
transferring part of the electrification infrastructure to the trains
themselves, through onboard energy systems, such as batteries or
supercapacitors, which also have
the benefit of making the trains

more autonomous. In parallel, we
are seeing requests for solutions
that help optimize the life-cycle
costs of the transport systems,
such as the re-injection of electricity into the rail networks, thus,
both reducing CO2 emissions and
costs," explained Alstom.
Alstom notes that the development of its Coradia iLint electric train powered by a hydrogen
fuel cell is the result of investing
to improve the environmentally-friendly aspects of its product
and solutions. The train has been
running passenger operation
since September 2018 and recently toured six states in Germany to
demonstrate its capabilities. The
company says the Coradia iLint is 100 percent emission free,
less noisy and offers comparable
acceleration and braking performance to a conventional Coradia

"Such

innovations are
also transferring
part of the
electrification
infrastructure
to the trains
themselves,
through
onboard energy
systems, such
as batteries or
supercapacitors,
which also have
the benefit of
making the
trains more
autonomous."
