Chicago Transit Authority To Add Dozens Of Electric Buses After Successful Tests



After over a year of testing, Chicago is ready to commit to all-electric buses.
The Chicago Transit Authority (CTA) took delivery of two electric buses in 2014, and found them satisfactory.
So the city now plans to purchase 20 to 30 all-electric buses over the next few years, as part of an overall modernization of its fleet.

The CTA claims to be the first major transit agency to put all-electric buses into daily revenue service. Its pair of buses have operated continuously since October 2014.
Both are 40-foot models made by New Flyer Industries.
Each is equipped with a 300-kilowatt-hour lithium-ion battery pack, which the CTA says provides a range of 80 miles.



Charging takes three to five hours, and is done overnight while the buses are idle. The pair have already carried around 100,000 passengers on 13 routes--racking up 25,000 in-service miles.
No significant mechanical issues cropped up during testing, according to the CTA. The buses' battery packs are intended to last their entire service lives--meaning about 12 years.

Officials claim the emissions reductions from operating the two buses is the equivalent of removing 14 internal-combustion cars from the road, and adds up to $39,000 in health-benefit savings.
In an "average year of use," the CTA expects each bus to save $25,000 in fuel, and $55,000 in public-health costs.
The agency will issue a request for proposals later this year, for both additional 40-foot electric buses and charging stations that will be placed along their routes.




The entire project will cost an estimated $30 to $40 million, which will come from a yet-to-be-finalized group of Federal funding sources, the CTA said. In addition to all-electric buses, the CTA will continue to operate diesel-electric hybrids, which currently make up about 15 percent of its fleet.

As part of a fleet modernization effort first announced by Mayor Rahm Emanuel in 2012, the CTA is also recently retired older vehicles that date back to 2000-2002, and performed overhauls on newer vehicles.
That includes adding particulate filters to some diesel buses, in order to reduce harmful particulate-matter emissions.
