The North Carolina airport issued a request for proposals this week asking companies to pitch a massive airport solar array that could be the largest in the state and would likely beat out Indianapolis International Airport for the largest airport solar installation in the country.
Charlotte Douglas had a small pilot project for solar, but hadn’t previously committed to such a large-scale investment in the technology.
“This is potentially going to bring us into a whole new ballpark,” Robert Phocas, Charlotte’s Energy and Sustainability Manager told the Charlotte Observer.
The airport is offering up 128 acres, which includes building rooftops and spaces between runways, as well as parking lots and structures. If the space were completely built out to its maximum density with solar panels, it could potentially produce 53 megawatts of solar electricity. Of course, natural limitations in space, connectivity and logistics will likely result in a much lower total.
Even if the total size of the solar array is half its potential, it could still be more than twice the size of the 12.5-megawatt solar installation at Indianapolis International Airport, which is currently believed to be the largest located at an airport.
Charlotte airport’s RFP states that whatever company wins the deal will own and maintain the solar panels for the first six years, paying a land-lease to the airport and selling the power to Duke Energy. After six years, the airport will have the option to buy the solar panels.
Charlotte Douglas joins a long list of airports that have ventured into solar investments.
The Chattanooga Airport in Tennessee is powered almost 90 percent by solar energy. Chicago’s Midway Airport recent installed solar panels. And thousands of solar panels power facilities at the Denver International and Austin-Bergstrom International airports.
Airports have struggled to make their operations more environmentally sustainable as thousands of jets take off from and land on their airstrips every month and hundreds of thousands of vehicles drive long distances to park in their parking lots. The carbon footprint of flying and the airline industry is massive.
To offset some of their environmental impacts and to reduce expenses for airports, which are typically managed by the cities they occupy, administrators have become creative.
In states where the incentives are good and utilities are willing to negotiate, solar is a perfect fit for the enterprises, which often have huge swaths of undeveloped land not suited to other types of development.
Charlotte’s RFP is open with room for developers to be creative – something they requested, Phocas added.
