Trauma centers, jet engines and the 2011 October storm
Serving Hartford County
Hartford’s critical loads are hospitals and aerospace. Hartford Hospital was the region’s first Level I trauma center and runs LIFE STAR, the state’s first air ambulance system. It coordinates with Connecticut Children’s pediatric trauma center for statewide coverage. Campuses like these keep standby generators and large tanks ready all year.
Across the Connecticut River, Pratt & Whitney is headquartered in East Hartford. Its campus sits beside the company’s former airfield, where Pratt & Whitney Stadium at Rentschler Field now stands. Manufacturing on that scale runs plant equipment, forklifts and truck fleets, and the suppliers around it do too.
The storm that set the bar
The late-October 2011 nor’easter dropped a record 12.3 inches of snow on Hartford. Statewide, 830,000 customers lost power, breaking the record set after Hurricane Irene earlier that year. The state’s Emergency Operations Center opened in Hartford. Some customers didn’t get power back until November, and many outages lasted 11 days.
That is the number to plan generator fuel around in Hartford, not one night. A full tank plus a refill plan is what keeps a hospital floor, a data room or a plant running through a week and a half without the grid.
Which FuelGo services fit Hartford
- Hospitals and campuses: scheduled generator fueling, plus fuel polishing and lab fuel testing.
- Aerospace and manufacturing: on-site delivery to plant tanks and mobile fleet fueling.
- Nor’easters: emergency fuel delivery once the lines are down.

How Fuel Gets to You
Mobile fueling or bulk delivery: which fits your Hartford site?
Three delivery formats. We’ll quote whichever fits your volume, site access and cost target.
Wet-Hose Fueling
Mobile fleet fueling
Overnight or day shift, fuel direct to each tank
A driver pulls into your yard after hours, fuels every truck or piece of equipment directly, logs each fill, and clears out before your crews arrive. No staff required on site.
Best for: Trucking fleets, delivery yards, rental fleets and service vehicles.
Tank Wagon Delivery
On-site tank fills
20 – 4,400 gallons per drop · same-day or scheduled
A smaller delivery truck fills your day tank, jobsite bulk tank or generator. The flexible option when volume varies or site access is tight.
Best for: Construction sites, generator refills, day tanks and smaller bulk storage.
Transport Load
Bulk transport delivery
Full transport loads to 7,500+ gallons · scheduled
Tractor-trailer delivery straight into large bulk storage. The lowest cost per gallon for high-volume buyers.
Best for: Data centers, large industrial sites, agriculture and rail yards.
