From essential supplies to vital infrastructure, manufacturing facilities play a crucial role in emergency response. But their complex operations and machinery rely heavily on uninterrupted power.

A power outage, compounded by faulty backup generators due to neglected fuel, can bring production to a standstill, hindering emergency response efforts and causing widespread disruption. Proactive fuel management ensures generators are ready to keep the wheels of production turning, even when the lights go out. 

How Degraded Fuel Cripples Your Emergency Generator

Back to top

The comforting hum of your backup generator lulls you into a false sense of security. It stands sentinel, promising unwavering power when darkness falls. But have you ever considered the silent enemy lurking within its fuel tank – degradation? Just like any perishable item, diesel fuel has a shelf life, and neglecting its care can transform your guardian angel into a silent saboteur during an emergency. 

The Accelerated Decline 

Modern diesel fuel, unlike its predecessors, degrades much faster, with an ideal lifespan of 6-12 months under perfect conditions. But those pristine scenarios rarely mirror the reality of your generator's fuel tank. Unlike gas stations with constant fuel turnover, your emergency reserve often sits stagnant for months, even years. This stagnant state accelerates the degradation process, turning your fuel into a ticking time bomb waiting to explode in your most critical moment. 

The Devastating Consequences 

Imagine the scene: a storm plunges your world into darkness. You rush to your generator, expecting to hear its comforting roar. Instead, silence. Degraded fuel has clogged injectors, gummed up lines, and rendered your lifeline useless. The consequences ripple outwards: 

  • Lost communication: Hospitals go dark, businesses grind to a halt, and communities are left isolated in the aftermath. 
  • Disrupted services: Essential services like water purification and medical equipment falter, jeopardizing lives and public safety. 
  • Financial losses: Downtime translates to lost revenue, damaged equipment, and potential legal repercussions.

Safeguarding Your Power Lifeline

REGULAR FUEL TESTING Schedule periodic testing to identify degradation before it becomes a problem.
FUEL ADDITIVES Utilize approved additives to stabilize fuel and slow down the degradation process. 
PROACTIVE MAINTENANCE Partner with a reliable fuel management service for expert handling, filtration, and monitoring.
PROPER STORAGE Ensure your fuel tanks are clean, well-maintained, kept filled at or slightly under the 90% legal fill limit, and protected from moisture and contamination.

How Long Does Fuel Last?

Many fuel refineries will tell you these days diesel fuel can be stored for 6-12 months in ideal conditions. This doesn’t impact diesel fuel at a point-of-sale location (gas station) to the same extent as an emergency generator fuel system.

At a gas station, there is a much more frequent turnover since customers are constantly purchasing fuel and draining down the bulk tanks leading to new fuel drops and turnover in those bulk tanks.  In an emergency generator fuel system when seldom used, the fuel can stay stagnant for several years or even decades.

Effects of Stagnant Fuel on Generator Performance and Longevity

Since diesel fuel is a refined oil product (hydrocarbon), it will ultimately naturally begin to break down into its pre-refined self in as little as 12 months, some say. As the fuel breaks down, there can be solid byproducts which lead to sediment and particulates within the fuel tank.

In addition, since fuel is a hydrocarbon, water is naturally integrated into its chemical makeup. Over time, the water can separate out from the fuel or condensation and debris can be introduced into your tank from the outside via vents or other means. Water in your fuel tank contributes to oxidation of metal components as well as bacterial and fungal growth (microbes).

All these factors may not seem very problematic at first glance, but they lead to serious fuel quality problems. Sediment and sludge can clog filters, damage pumps and lead to generator loss of prime and ultimate failure.

Water contributes to microbial growth. Microbes and their particulates can clog filters, and microbe excrements lead to corrosion of steel fuel tanks, piping and/or pumping equipment. Fuel quality problems like these lead to emergency generator and/or fuel system failure.

Best Practices for Fuel Systems Sampling

Why would we send a sample from the tank bottom that is half full of water only for the lab to tell us there is water in your fuel? We already know there is a problem if the fuel sample has visual evidence of water, therefore collection of a representative sample from above the water line and sending that for laboratory analysis is generally a better practice and more useful in designing or enhancing the overall fuel treatment action plan.

Fuel samples need to be collected in a fashion that represents the fuel that is picked up by the pumps feeding the generator or smaller holding tanks (day tanks).  This is generally 1”- 6” inches from the bottom of the tank, depending on the fuel tank system.  Often there is no reason to pull a sample from the very bottom of the tank or from generator fuel filters except to generally observe them. 

What are Critical Fuel Systems Compliance Regulations?
