600 Chargers to Support eGSE Vehicles Saving $2.8 Million per Year
Battery electric ground support vehicles will save some $2.8 million per year at the Seattle-Tacoma International Airport, the Port of Seattle says, reporting a $31 million project with partners including Alaska Airlines and the Western Washington Clean Cities organization.
“The eGSE project here at SeaTac should serve as an example of how energy efficiency is not only good for the environment, but is also a smart financial investment,” U.S. Congressman Adam Smith said in a Port release.
“We must continue to invest in alternative energy technologies that protect consumers, reduce greenhouse gas emissions, and strike a balance between moving away from our dependence on fossil fuels while mitigating the economic impact of that transition,” Smith said.
576 Charging Locations by September
Suppliers including Charlatte for eGSE baggage tugs, bag ramps and pushback vehicles, and AeroVironment for high-power PosiCharge equipment to support them, are among the major industrial beneficiaries.
“As many as 650 vehicles could eventually be covered by electric technology and make a huge difference in the airport’s carbon footprint,” said Courtney Gregoire, co-president of the Port of Seattle Commission.
The Sea-Tac electrification project includes bright yellow charging corrals with smart, fast-charging plug-ins for vehicles to receive a full charge in less than four hours. A first phase provides 296 charging locations. A second phase cover the rest of the Sea-Tac terminal for a total of 576 charging locations by September.
‘Alaska Airlines Has Taken the Lead’
“Alaska Airlines has taken the lead in this green opportunity,” states the Sea-Tac announcement, with 204 electric vehicles (146 with Alaska, 58 with Horizon). “Alaska’s conversion to electric vehicles is the equivalent of taking 360 passenger vehicles off the road for a year,” the Port says.
Funding came in large part through federal grants, including $5 million from the U.S. Department of Energy through a grant with the Western Washington Clean Cities Coalition. An additional $3.5 million came from a Federal Aviation Administration grant.
The investment in eGSE is just part of the story at Sea-Tac, which notes that
- centralized pre-conditioned air for aircraft parked at gates will save $15 million in airline fuel costs (operation began in July 2013);
- the 48 electric vehicle charging stations in the airport garage, installed from 2010 through late 2013, is the most of any airport in North America;
- a fleet of compressed natural gas/CNG buses moves customers between the terminal and the Sea-Tac rent-a-car facility;
- the airport requires taxis to use CNG vehicles or have high efficiency engines of 45 miles per gallon or better (2011),
- a centralized off-aircraft recycling system of large capacity, computer-monitored compactors reduces waste sent to landfills, decreases air emissions, improves ramp safety, saves more than $250,000 each year and reduces pickup trips by 75% (2010); and
- a partnership with Alaska Airlines, Boeing, other airports and Washington State University is supporting aviation biofuel development in the Pacific Northwest.
