John F. Kennedy Worldwide Airport, the busiest airport for worldwide site 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 meant because the world’s largest and most effective, with “no confusion and no congestion.”
As airport site 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 modifications and reconfigurations. Now JFK is present process a $19-billion redevelopment challenge 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 scale of the present Terminal 1, which opened in 1998.
The New Terminal One could have what its creators have mentioned is the biggest photo voltaic array at any US airport, which can 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 mentioned in saying plans for the photo voltaic array, “Guests from around the globe might be energized from the second they enter the New Terminal One at JFK.”

It received’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’s going to even be a blended system in order that, at any level, the electrical gadgets that hold issues shifting at a busy aerodrome might be working on 50% clear power.
The 6.63 megawatts (MW) of photo voltaic power might be a part of a 12 MW microgrid. Situated in 4 clusters {of electrical} era infrastructure strategically positioned across the new terminal to create a single sensible, resilient power system, this microgrid may even embody 3.84 MW of gas cells and 1.5 MW/3.34 MWh of battery power storage to stability electrical demand and enhance energy high quality. The system can function independently from or whereas linked to the primary energy grid.
Advantages of electrical floor help automobiles
The microgrid will provide the facility to cost the various varieties of electrical automobiles distinctive to airports.
Airports make use of an unlimited array of automobiles massive and small of their operations. Some function airside (after safety), and a few landside, however their mission is essential to individuals (and baggage) shifting. There are various operations that happen behind the scenes (which passengers hardly ever 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 understand that ICE-powered automobiles convert 20% to 30% of their gas into propulsion, whereas EVs convert 80% to 90%.
Case examine: Electrical buses exchange 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 a variety 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 in addition 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 mentioned it decreased its greenhouse fuel emissions by roughly 40,000 tons every 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 may in any other case have spewed into native residential neighborhoods within the borough of Queens in New York Metropolis, the place the aerodrome is positioned.
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 challenge to standardize its tow tractor (tugger) fleet throughout all its crops worldwide. Eagle designed the RTT sequence A/C electrical line of tow tractors with in depth enter from GM operators, in addition to security and manufacturing engineers.
The RTTs provide alternative charging that permits 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) they usually 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 individuals trams to rocket launch platforms effectively, reliably and safely,” the corporate mentioned.
Electrification on the New Terminal One
Airports function 24/7, and they’re robust environments for gear that continues to be outside in rain, snow, sub-zero temperatures and different inclement situations. Accordingly, the much less probably 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 shifting components and minimal upkeep in comparison with the alternate options, are due to this fact best for airport environments.
Airside operations have relied on inner combustion-powered automobiles for many years, though that’s slowly altering. On the tarmac, using EVs resembling tugs, baggage carts and passenger shuttles is gaining acceptance, and JFK’s New Terminal One—with the intention to meet its sustainability targets—is aiming to exchange all such automobiles in use on the present Terminal 1 at a speedy tempo.
Tim Castaldy, a Senior Electrical Designer at Nevada-based PK Electrical, examined the impression of EVs on airport floor transportation in a latest weblog put up, and took the time to supply real-life illustrations of the next points that have been put forth to him in an interview overlaying his work with Denver Worldwide Airport, an electrification consumer.
Well being points – Ramp employees and others who work airside are always uncovered to poisonous emissions, and plenty of face well being points in consequence, Castaldy mentioned.
Value-benefit ratio – Whereas electrical airside automobiles are noticeably dearer than conventional-powered ones, over the lifetime of a car, the associated fee financial savings accrued from decrease upkeep prices in addition to the decrease value of electrical energy versus diesel or gasoline have 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 a variety of well being points from non-airport employees with residences close to airports, so it isn’t exhausting 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 hundreds, Castaldy underscored.
Chilly climate operation – Electrical airside automobiles have been discovered to be extra dependable in chilly climate than their counterparts, Castaldy mentioned. “Chilly climate reliability (is a robust justification for) EV tugs,” he mentioned. “The ICE tugs can have issue 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 challenge via an Vitality as a Service contract, primarily a pay-for-performance, off-balance-sheet financing resolution, which can permit the Port Authority to implement power effectivity initiatives with zero upfront capital expenditure. Over the lifetime of the contract, AlphaStruxure might be accountable not just for the development, but in addition 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 powerful, “it’s doable however it relies upon,” in line 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 as a consequence of the truth that the microgrid will present total electrical energy to the terminal and automobiles, assembly demand for hundreds as much as its manufacturing capability. Since we can not direct electrons to particular hundreds, the microgrid will provide no matter demand exists, restricted to its obtainable output.”
Nonetheless, given the legislation of variable constants and proportions, it’s probably that on uncommon—or maybe not so uncommon—events, some EVs will obtain 100% photo voltaic power.
