GSE at an AeroVironment PosiCharge station in Seattle-Tacoma International Airport. (Port of Seattle)
Our industrial EV charging systems that have been powering Seattle-Tacoma International Airport's (Sea-Tac) electric ground service equipment are not only improving air quality, but they are also helping to save millions for airlines. The following article published in IHS Airport 360 details how the airport's investment in our system helps to improve the bottom line.
"The eGSE program aims to save airlines USD 2.8million per year
Seattle-Tacoma International Airport (Sea-Tac) is engaged in an ambitious USD31 million project to install more than 600 electric charging stations to power the airport's growing fleet of electric ground service equipment (GSE).
The move from fossil fuels to electric-powered GSE is projected to save USD2.8 million in airline fuel costs (equivalent to nearly 1 million gallons) and 10,000 tonnes of greenhouse gas emissions (the equivalent of 1,900 less cars on the road).
The first phase of the Port of Seattle's Electric Ground Support Equipment (eGSE) project involved the installation of 256 charging points throughout Concourses C, D, and the airport's North Satellite building in 2014.
The rest of the stations are to be installed at Concourses A, B, and in the South Satellite building by the end of 2015. As of November 2014, airlines were using about 80 per cent of the available charging stations.
Operated by the Port of Seattle, Sea-Tac is the fifteenth-largest airport in the United States. Passenger traffic there hit a record 37.5 million in 2014.
"We are currently working with our airline partners on the south end of the airfield to time the installation of the rest of the eGSE charging stations," said Sea-Tac media spokesman Perry Cooper. "We have to work through their testing and timing for changing out their equipment."
Cooper noted that several airlines were interested in getting involved, although "we just don't have a confirmed turnover timeline yet". For now, Alaska Airlines has been using charging points at the north end of the airport "and is very happy with their performance".
After a competitive tender in 2012, California-based firm AeroVironment won a USD8 million contract to supply its PosiCharge system to Sea-Tac. The bright yellow charging corrals can fully charge a wide range of GSE such as pushback vehicles, baggage tugs, and belt loaders within four hours.
The smart chargers are equipped to recognise a battery's size and voltage and provide a charge profile tailored to the specific battery. This feature of the PosiCharge system means that driver downtime is minimised and that batteries are charged within their safety parameters, extending their life and ensuring warranties are not voided.
In addition, as more vehicles are hooked up to the charging corral, it is able to assess which vehicle needs to be charged up in priority and meters out power accordingly."
