John F. Kennedy Worldwide Airport, the busiest airport for worldwide visitors in North America, at all times appears to be reinventing itself. It opened in 1948 as New York Worldwide Airport, though it was usually referred to then as Idlewild. The airport was supposed because the world’s largest and best, with “no confusion and no congestion.”
As airport visitors grew, so did the necessity for bigger and improved services. In 1954, architect Wallace Harrison designed a plan that gave main airways their very own terminals. The outcome was known as Terminal Metropolis: 5 airways had their particular person terminals, three airways shared a sixth terminal, and overseas airways used the worldwide arrivals terminal.
Since then, there have been a number of adjustments and reconfigurations. Now JFK is present process a $19-billion redevelopment venture that, amongst a number of new terminals, consists of the two.4-million square-foot, 23-gate terminal dubbed the New Terminal One, which would be the largest at JFK—greater than twice the dimensions of the present Terminal 1, which opened in 1998.
The New Terminal One could have what its creators have stated is the biggest photo voltaic array at any US airport, which is able to energy a fleet of electrical automobiles used on the terminal each landside and airside. Development of the large array, consisting of greater than 13,000 photo voltaic panels on the terminal’s roof, started in 2024.
As Port Authority of New York and New Jersey Chairman Kevin O’Toole stated in saying plans for the photo voltaic array, “Guests from world wide can be energized from the second they enter the New Terminal One at JFK.”

It gained’t solely be the passengers who’re energized. The New Terminal One’s photo voltaic array will help roughly 50% of the terminal’s power necessities—an quantity of power that might energy greater than 3,500 common US properties. It would even be a blended system in order that, at any level, the electrical units that preserve issues transferring at a busy aerodrome can be working on 50% clear power.
The 6.63 megawatts (MW) of photo voltaic power can be a part of a 12 MW microgrid. Situated in 4 clusters {of electrical} technology infrastructure strategically positioned across the new terminal to create a single sensible, resilient power system, this microgrid can even embody 3.84 MW of gas cells and 1.5 MW/3.34 MWh of battery power storage to steadiness electrical demand and enhance energy high quality. The system can function independently from or whereas linked to the principle energy grid.
Advantages of electrical floor help automobiles
The microgrid will provide the ability to cost the various sorts of electrical automobiles distinctive to airports.
Airports make use of an enormous array of automobiles giant and small of their operations. Some function airside (after safety), and a few landside, however their mission is important to folks (and baggage) transferring. There are various operations that happen behind the scenes (which passengers not often see), together with upkeep, baggage dealing with and plane motion.
Many airport automobiles are fairly seen to passengers, together with baggage carts, baggage tugs, pushback automobiles, passenger shuttles and conveyor belt loaders. What passengers don’t usually see embody the automobiles transporting baggage to storage operations in warehouses, these utilized by cleansing companies, refrigerated vans for transporting meals and meal trays, and automobiles that deal with recycling and waste administration.
Because the transfer from diesel- or LP-powered automobiles to electrical automobiles takes place at airports, it’s vital to remember that ICE-powered automobiles convert 20% to 30% of their gas into propulsion, whereas EVs convert 80% to 90%.
Case examine: Electrical buses substitute diesel bus fleet at JFK
The Port Authority took an enormous leap into electrification 4 years in the past when it changed quite a few ICE buses that carry passengers to the terminal with the driverless light-rail JFK AirTrain, which makes use of electrical energy. Even after the launch of the JFK AirTrain, the Port Authority nonetheless had quite a lot of diesel coach buses.
After a number of years of planning, the Port Authority changed its inter-terminal diesel-powered bus fleet in 2019 not solely at JFK but additionally at LaGuardia and Newark Liberty airports, with 36 battery-operated Proterra Catalyst E2 Electrical shuttle buses.
By taking the ICE-powered buses—which had consumed about 240,000 gallons of diesel gas every year—out of service at JFK, the company stated it decreased its greenhouse fuel emissions by roughly 40,000 tons each year. Additionally, the 40-foot buses eradicated the emissions of roughly 2,000 kilos (907 kg) of nitrous oxide and 150 kilos of particulate matter yearly that will in any other case have spewed into native residential neighborhoods within the borough of Queens in New York Metropolis, the place the aerodrome is situated.
Every bus can journey roughly 230 miles on a cost, and it takes 4 hours to completely recharge the bus.
Case examine: Early electrical tugs designed particularly for GM
In 2006, GM got here to Eagle Tugs with a venture to standardize its tow tractor (tugger) fleet throughout all its vegetation worldwide. Eagle designed the RTT collection A/C electrical line of tow tractors with intensive enter from GM operators, in addition to security and manufacturing engineers.
The RTTs supply alternative charging that enables the tuggers to deal with three shifts of operation with out having to exchange batteries, they’re ergonomically right (being the one tuggers to supply operators stand-up and sit-down operation) and so they ship a 1,000-hour preventative upkeep schedule versus the 200-hour preventative upkeep schedule of different tow tractors.
In 2009, Eagle introduced its experience in designing and manufacturing A/C electrical tow tractors to the aviation market.
“With Eagle Electrical Tow Tractors, you may tow and push something from folks trams to rocket launch platforms effectively, reliably and safely,” the corporate stated.
Electrification on the New Terminal One
Airports function 24/7, and they’re robust environments for gear that continues to be outdoor in rain, snow, sub-zero temperatures and different inclement circumstances. Accordingly, the much less doubtless it’s {that a} pushback/tow tractor will fail to begin or carry out, the higher it’s for all involved, from passengers to rampers to pilots to air-traffic controllers. EVs, given their fewer transferring elements and minimal upkeep in comparison with the alternate options, are due to this fact best for airport environments.
Airside operations have trusted inside combustion-powered automobiles for many years, though that’s slowly altering. On the tarmac, using EVs corresponding to tugs, baggage carts and passenger shuttles is gaining acceptance, and JFK’s New Terminal One—as a way to meet its sustainability targets—is aiming to exchange all such automobiles in use on the present Terminal 1 at a fast tempo.
Tim Castaldy, a Senior Electrical Designer at Nevada-based PK Electrical, examined the impression of EVs on airport floor transportation in a current weblog put up, and took the time to supply real-life illustrations of the next points that had been put forth to him in an interview overlaying his work with Denver Worldwide Airport, an electrification shopper.
Well being points – Ramp employees and others who work airside are consistently uncovered to poisonous emissions, and plenty of face well being points because of this, Castaldy stated.
Price-benefit ratio – Whereas electrical airside automobiles are noticeably costlier than conventional-powered ones, over the lifetime of a car, the fee financial savings accrued from decrease upkeep prices in addition to the decrease value of electrical energy versus diesel or gasoline had been verifiable.
Noise air pollution – EVs are a lot quieter than their non-electric counterparts and reduce the impression of noise air pollution on the well being of airport employees. The transfer to telecommuting within the first years of the pandemic led to the disclosure of quite a lot of well being points from non-airport employees with residences close to airports, so it isn’t arduous to think about the well being impression to airport employees themselves.
Effectivity – Since EVs have considerably extra low-end torque, they are perfect for towing plane and extra effectively transferring heavy masses, Castaldy underscored.
Chilly climate operation – Electrical airside automobiles have been discovered to be extra dependable in chilly climate than their counterparts, Castaldy stated. “Chilly climate reliability (is a robust justification for) EV tugs,” he stated. “The ICE tugs can have problem beginning in chilly climate, which isn’t the case with the EVs.”
How the electrons will get to the New Terminal One’s EVs
The contractor for the microgrid, AlphaStruxure, is financing the venture via an Power as a Service contract, basically a pay-for-performance, off-balance-sheet financing resolution, which is able to permit the Port Authority to implement power effectivity tasks with zero upfront capital expenditure. Over the lifetime of the contract, AlphaStruxure can be accountable not just for the development, but additionally the operation and upkeep of the microgrid.
Will the bottom companies EVs be working solely on photo voltaic power at sure junctures? The reply is a convincing, “it’s potential but it surely relies upon,” in accordance with Michelle Charello, VP of Advertising at AlphaStruxure. “At this stage, AlphaStruxure and the New Terminal One can not pinpoint the precise contribution from the microgrid attributable to the truth that the microgrid will present general electrical energy to the terminal and automobiles, assembly demand for masses as much as its manufacturing capability. Since we can not direct electrons to particular masses, the microgrid will provide no matter demand exists, restricted to its out there output.”
Nonetheless, given the regulation of variable constants and proportions, it’s doubtless that on uncommon—or maybe not so uncommon—events, some EVs will obtain 100% photo voltaic power.
