Diesel Fuel Tanks for Standby Generators

Diesel generators are one of the most commonly used commercial generators in the backup power solution market. Aside from power generation, they are known to be highly reliable, built with quality, sturdy, require lower maintenance than their natural gas counterparts, and versatile in that they can be used for a variety of applications across different industries. While diesel generators may be the most common generator option, their drawbacks include slightly higher cost of acquisition when compared to their natural gas counterparts and fuel capacity.

A diesel generator’s power generation capabilities are limited to the size of their fuel tanks. The more diesel fuel the tank can hold, the longer the generator will be able to run. If using a standby diesel generator, also referred to as a backup diesel generator for your business or facility, it is important to take note of the diesel fuel supply levels. If you are anticipating potentially long duration of power outages, be sure to create a contingency plan that covers not only the operation of the diesel generator, but more importantly, resupply of diesel fuel. If there is inclement weather, such as a blizzard or severe snowstorms, will diesel fuel delivery companies be able to make it through the storm to resupply the generator? If that is not an option, will there be staff on-hand and a local gas station to resupply? Quite simply, you may decide to purchase and store fuel on-site before the storm hits.

In addition to these steps, it’s also possible to acquire diesel fuel day tanks. Day tanks are portable diesel base tanks that are designed to extend the run-time of your diesel generator. Day tanks are a viable solution if there are delivery companies in your area that are able to accommodate your needs, even in critical situations such as disaster recovery.

In regards to the diesel fuel tank, the most common tank style is the diesel base tank, which is mounted directly beneath the generator. This allows the generator set to be moved and installed as one piece, with the drawback being the fuel supply is limited to the size of the base tank. This means that the maximum run-time of a diesel generator is limited to the size of the tank, especially when taking the height of the tank into consideration. A general rule of thumb is that the greater the height of the diesel base tank, the more diesel it can hold, which results in a longer duration of run-time.

While generator height is a good preliminary factor in determining diesel generator run-time, it is important to actually calculate the fuel consumption rate of a diesel generator. Diesel fuel tank run-times are measured by the diesel generator fuel consumption rate when the generator is at 100% load. Measuring the fuel consumption rate at 100% load allows you to create a failure scenario that anticipates the worst possible situation that would require 100% use of the generator. In actuality, the diesel fuel consumption rate may be lower and the actual run-time in real-world scenarios when compared to the test scenarios. This is because it is generally uncommon to require diesel generators to run at full load.

While there is much to consider about diesel fuel base tanks, one of the most important factors to consider are code requirements. Depending on location, local codes for diesel base tanks must be adhered to in addition to diesel generator run-time requirements. When looking at diesel fuel base tanks, be sure to search for the UL listing that adheres to your project and locale and look for a diesel fuel base tank that satisfies those requirements.

Conclusion

Diesel generators are robust backup power solutions, but are limited to the size of the diesel base tanks.
