Overview
Green Bay Austin Straubel International Airport (GRB) is the third largest airport in the state of Wisconsin, offering business and leisure travel by five major airlines. As a gateway to Lambeau Field, it is also the home airport for the Green Bay Packers. To further support its passengers’ airport experience, GRB wanted to provide easy access charging for the growing number of electric vehicle (EV) owners. They also sought to do so with a renewable energy source to incorporate sustainability, and one that would have minimal budget impact.
Challenge
The airport knew they needed to look into EV charging as a way to better support their customers and were looking at all options. In partnership with EnTech Solutions, they were able to develop a plan to install a clean EV charging solution to sustainably meet the needs of their guests.
Solution
EnTech Solutions installed an Xcape™ X3 EV charging solution utilizing a single station Wallbox charger. The primary source of energy for the system is a 19.7 kW DC solar array with a grid connection for backup power. EnTech was able to provide the installation at no charge to the airport, utilizing a “pay-per-charge” model to fund it. In addition, when the charger is not being used, the clean electricity is transferred to the electric grid for use by the community.
Because the charger and solar field are located within Federal Aviation Administration (FAA) controlled space, EnTech Solutions also conducted and provided documentation for the required glare study.
Outcome
EnTech Solutions was able to provide GRB with a clean EV-charging solution that met their size, cost and sustainability needs. This turnkey system is fully supported, with EnTech providing ongoing operations and optimization.
