Hurricane Fuel Preparedness for Florida Businesses

Florida hurricane season runs from June 1 through November 30, and for businesses that depend on continuous power, refrigeration, or fleet operations, fuel preparedness can determine whether you weather the storm or suffer catastrophic losses. Hospitals that lose generator power risk patient safety. Grocery stores that lose refrigeration face hundreds of thousands of dollars in spoiled inventory. Construction companies that cannot fuel equipment lose days or weeks of project timeline.

This guide covers everything Florida businesses need to know about fuel preparedness before, during, and after a hurricane.

The 96-Hour Rule

Emergency management experts recommend that businesses maintain enough fuel to run critical systems for at least 96 hours (4 days) without resupply. This accounts for the typical time between a major hurricane landfall and the restoration of normal supply chains — fuel terminals reopening, roads clearing, and delivery trucks being able to reach customers.

For many businesses, this means storing significantly more fuel than they use in normal operations. A hospital generator consuming 50 gallons per hour at full load needs 4,800 gallons to run for 96 hours. A data center with multiple generators may need 10,000 or more gallons. Even a small business with a 20kW generator needs roughly 100 to 150 gallons for 96 hours of runtime.

Calculate your 96-hour requirement well before hurricane season begins. Do not wait until a storm is in the Gulf to discover that your existing fuel supply covers only 18 hours of generator runtime.

Pre-Season Fuel Checklist

Complete these steps by May 31 — before hurricane season officially begins.

Inventory your generators. Document every generator at every facility: make, model, fuel type, kilowatt rating, fuel consumption rate at full load, and tank capacity. Identify which generators power critical systems (life safety, refrigeration, data, communications) versus non-essential loads.

Calculate fuel requirements. For each generator, multiply the full-load consumption rate by 96 hours. This is your minimum fuel requirement. Add 20 percent as a safety buffer for higher-than-expected loads and inefficiencies. If you have multiple generators, sum the totals.

Inspect fuel storage. Test all storage tanks for leaks, corrosion, and proper venting. Replace deteriorated fuel lines and fittings. Verify that fuel dispensing equipment (pumps, nozzles, meters) operates correctly. Clean tanks if fuel has been sitting for more than 6 months — diesel degrades and can develop microbial growth in humid Florida conditions.

Top off fuel supply. Fill all storage tanks to capacity in May or early June. Fresh fuel has a shelf life of 6 to 12 months when properly stored. If you do not use this fuel during hurricane season, rotate it into normal operations and refill before the next season.

Establish a fuel delivery relationship. Do not wait until a storm is 48 hours out to call a fuel company for the first time. Establish an account with a fuel delivery provider during the off-season. Providers who know your facilities, access routes, and fuel requirements can respond faster during emergencies.

At BettyJet Fueling, we encourage all commercial customers to complete a hurricane preparedness consultation before June 1. We document your generator inventory, calculate fuel requirements, and establish priority delivery protocols so that when a storm threatens, we are ready to respond immediately.

Pre-Storm Fuel Protocol (72 to 48 Hours Before Landfall)

When a hurricane threatens, the window for action narrows quickly. Fuel terminals typically suspend operations 24 to 48 hours before projected landfall. If you have not ordered fuel by 72 hours out, you may not get it.

At 72 hours before projected impact, top off all fuel storage tanks to maximum capacity. Fuel all fleet vehicles to full. Order additional fuel for any shortfalls identified in your 96-hour calculation. Confirm delivery schedules with your fuel provider.

At 48 hours, verify all deliveries have been completed. Test-run every generator under load for at least 30 minutes to confirm operation. Secure portable fuel containers. Position fuel where it will be accessible after the storm, away from potential flooding areas or falling debris.

Generator Fuel Requirements by Size

Understanding how much fuel your generators will consume is critical for planning. Here are approximate consumption rates at full load for common generator sizes:

A 20kW generator consumes approximately 1.6 gallons per hour of diesel. A 50kW generator uses about 3.5 gallons per hour. A 100kW unit burns roughly 7 gallons per hour. A 200kW generator consumes approximately 14 gallons per hour. A 500kW generator uses about 36 gallons per hour. A 1,000kW (1MW) generator consumes roughly 71 gallons per hour.

Remember: actual consumption varies based on load percentage, ambient temperature, altitude, and generator condition. Generators running at 50 percent load consume roughly 75 percent of their full-load fuel rate — not 50 percent. Always plan for higher consumption than you expect.

During the Storm

Once the hurricane arrives, limit generator operation to critical loads only. Running non-essential systems wastes fuel that you may desperately need later. Designate someone to monitor fuel levels every 4 to 6 hours during the storm and for the first 48 hours after.

Keep detailed records of fuel consumption during the event. This information is essential for insurance claims, FEMA reimbursement applications, and future planning. Note the date, time, generator ID, fuel level, and gallons added at each reading.

Post-Storm Fuel Delivery

After the storm passes, contact your fuel delivery provider immediately. Supply chains typically restore in 48 to 96 hours after landfall, but demand spikes dramatically as businesses, hospitals, and government agencies all need fuel simultaneously.

Customers who have pre-established relationships with fuel providers receive priority service over first-time callers. At BettyJet Fueling, our emergency line — (509) 713-4570 — operates 24/7 during declared emergencies. Pre-registered customers receive priority scheduling based on criticality (healthcare, life safety, and essential services first).

Post-storm fuel delivery may require flexible logistics. Roads may be blocked, access routes changed, and normal delivery points damaged. Communicate any access issues to your fuel provider immediately so they can plan alternative routes.

Fuel Storage Tips for Hurricane Season

Store fuel in properly rated above-ground tanks with secondary containment. Anchor tanks to prevent movement during high winds. Position tanks on elevated pads in flood-prone areas. Mark tanks clearly with fuel type, capacity, and emergency contact information. Maintain spill kits near all storage locations.

For portable fuel containers, use only UL-listed or FM-approved containers. Store them in ventilated areas away from ignition sources. Never store fuel containers indoors or in occupied buildings.

Building Your Hurricane Fuel Plan

Every Florida business should have a written hurricane fuel plan that documents generator inventory and fuel requirements, identifies storage capacity and locations, establishes a relationship with a fuel delivery provider, sets pre-storm fueling triggers (72 hours and 48 hours), assigns responsibility for fuel monitoring during events, and includes emergency contact information for fuel delivery.

Review and update this plan annually before June 1. Share it with your property manager, facility team, and fuel provider. A plan that exists only in someone's head is not a plan — it is a hope.

Hurricane preparedness is not about predicting whether a storm will hit. It is about ensuring your business survives when one does.
