Airport Ground Support Equipment (eGSE) & Rental Car CONRAC Solar+BESS Microgrids
Airports and airlines electrifying airside Ground Support Equipment (baggage tugs, narrow/widebody pushback tractors, belt loaders, lavatory trucks) and Consolidated Rental Car (CONRAC) turnaround decks face severe feeder capacity limits and FAA glare compliance rules. Top-deck parking structure solar canopies with anti-reflective low-glare glass and containerized BESS shave multi-megawatt flight-bank turnaround spikes.
Unmitigated Utility Grid vs. Solar + BESS Microgrid Architecture
| Engineering Parameter | Unmitigated Utility-Only EVSE | Solar Canopy + BESS Microgrid | Operational & Capex Advantage |
|---|---|---|---|
| FAA Solar Glare & Ocular Impact Compliance | Standard specular glass panels (Risk of ATCT air traffic control tower glare) | Deep-textured anti-reflective (AR) glass modeled via Sandia/ForgeSolar SGHAT tool | Guarantees zero yellow/red ocular glare toward Air Traffic Control Tower & approach paths |
| Airside Flight-Bank Charging Surges | 40 eGSE tugs & belt loaders plug in simultaneously between flight banks | Multi-channel smart DC GSE chargers buffered by airside LFP BESS | Delivers fast 25-minute gate turnaround boosts without overloading concourse substations |
| CONRAC Rental Car Quick-Turnaround Deck | 100+ returned rental EVs hitting 50 kW–150 kW DCFCs at 4:00 PM | Top-deck CONRAC solar canopy (1.5–4.0 MW) feeding lower-deck DCFC busways | Turns the exposed concrete top deck of the parking garage into a megawatt power plant |
| FAA VALE + IRA §6417 Funding Stack | 100% funded by airline rates & charges or Passenger Facility Charges (PFCs) | FAA Voluntary Airport Low Emissions (VALE) grant + IRS §6417 30%–50% cash refund | Slashes net airport authority capital cost by up to 75%–85% |
24-Hour Depot Load Profile & 15-Minute Peak Shaving Dispatch
| Shift / Operating Window | EV Fleet Load (kW) | Solar Output (kW) | BESS Dispatch (kW) | Net Utility Meter (kW) |
|---|---|---|---|---|
| 06:00 – 10:00 (Morning Departure Bank & eGSE Turnaround) | 1,200 kW | 650 kW | +250 kW | 300 kW |
| 10:00 – 15:00 (Midday CONRAC Rental Return & Solar Peak) | 1,650 kW | 2,400 kW | -750 kW (Charging Airside/CONRAC BESS) | 0 kW |
| 15:00 – 20:00 (Afternoon Hub Flight Bank + Peak TOU) | 2,200 kW (Peak eGSE + Rental Turnaround) | 550 kW | +1,350 kW (BESS Peak Shaving) | 300 kW (Flat Concourse Feeder Demand) |
| 20:00 – 06:00 (Overnight Ramp Fleet Conditioning) | 900 kW | 0 kW | 0 kW | 900 kW (Off-Peak Airport Primary Rate) |
3-Step Commercial Engineering & Commissioning Protocol
FAA Form 7460-1 Airspace & ForgeSolar Glare Hazard Analysis
Run ocular impact simulations across all runway approach paths and the Air Traffic Control Tower (ATCT) cab, and file FAA Form 7460-1 Notice of Proposed Construction.
CONRAC Top-Deck Column Transfer Structural Engineering
Anchor solar canopy steel columns directly into existing precast/post-tensioned parking garage column capitals to transfer wind and seismic loads without stressing deck slabs.
Airside Multi-Port eGSE Charger & BESS Microgrid Integration
Deploy 80V DC / 350V–800V DC multi-port airside chargers tied to a concourse BESS microgrid controller.

Frequently Asked Engineering & Tax Equity Questions
Can public airport authorities receive a direct cash check from the IRS for solar canopies and BESS?
Yes. Municipal and regional airport authorities are instrumentalities of state/local government eligible for IRS Section 6417 Elective Direct Pay, allowing them to receive a direct cash refund from the U.S. Treasury equal to 30%–50% of the solar canopy and battery storage installation cost.
How do airport solar arrays avoid causing glare for pilots and air traffic controllers?
Airport solar projects use specialized deep-textured anti-reflective (AR) glass modules installed at low tilt angles (5°–10°) oriented away from final approach corridors, verified prior to permitting using the FAA-accepted Sandia Solar Glare Hazard Analysis Tool (SGHAT / ForgeSolar).
