Sub-base fuel tanks are crucial for emergency and standby power generation in industrial applications. They are placed above ground, beneath the base of the generator set, and are often rectangular and double-walled to prevent spillage. Sub-base tanks are popular for their compactness, reduced space requirements, and ability to provide between 24 and 72 hours of generator runtime. These tanks are commonly used for storing less than 1,000 gallons of fuel, and custom designs are available for specific applications. The selection of a sub-base tank involves considering factors such as emergency stock, storage capabilities, and lead times for fuel supply and consumption. While sub-base tanks offer advantages, there is no one-size-fits-all solution, and alternatives like underground or above-ground tanks may be preferred for greater fuel capacity.

Sub-base tanks are rectangular and double-walled, preventing spillage
Sub-base fuel tanks are an important component of power generation systems, ensuring an uninterrupted fuel supply for generators. These tanks are typically installed beneath the generator set, providing a compact and integrated solution for emergency power generation.
One of the key advantages of sub-base tanks is their ability to prevent spillage. Their unique rectangular and double-walled design contributes significantly to spill prevention. The double walls act as an extra layer of protection, reducing the chances of fuel leakage. This feature is especially important considering the hazardous nature of the liquids stored in these tanks, such as flammable fuels and combustible liquids.
The rectangular shape of sub-base tanks also plays a crucial role in optimising space utilisation. By being located directly under the generator, sub-base tanks help reduce the overall space requirements of the power generation system. This makes them ideal for facilities with limited space, providing a compact and efficient solution for emergency power needs.
Furthermore, the design of sub-base tanks prioritises safe fuelling practices. The tank fill system is carefully engineered to prevent spillage during the refuelling process. Additionally, the inlet valve is designed to automatically close when the tank reaches 95% of its capacity, further reducing the risk of overfilling and spillage.
While sub-base tanks offer the benefit of spill prevention, they tend to have smaller capacities compared to their counterparts. Sub-base tanks are typically suitable for storing less than 1,000 gallons of fuel. For facilities with higher fuel requirements, larger underground or above-ground tanks might be more appropriate options.

They are installed above ground, beneath the base of the generator set
Sub-base fuel tanks are installed above ground, but beneath the base of the generator set. They are rectangular and double-walled, which helps to prevent spillage. They are designed to have no spillage during the filling process, with the inlet valve automatically closing when the tank is 95% full. Sub-base tanks are often smaller than other types of fuel tanks and are best suited for storing less than 1,000 gallons of fuel.
Sub-base tanks are a popular choice for emergency generators as they can be integrated with the generator, reducing space requirements. They are also beneficial for facilities with a single emergency generator installed outdoors in a weather-protected enclosure. The compact design of sub-base tanks means that all fuel accessories and piping can be pre-installed, resulting in lower permitting and installation costs.
When selecting a sub-base tank, it is important to consider the amount of fuel required in case of an emergency or delay in fuel delivery, as well as the storage capabilities available. The lead time for fuel supply and the amount of fuel needed to cover this period should also be considered.
Sub-base fuel tanks can be customised to meet specific requirements, with storage capacities of several thousand gallons. However, to avoid EPA registration requirements, they are typically specified to store less than 550 gallons. When a longer runtime is required, a supplemental tank can be installed remotely to supply fuel to the sub-base tank on demand. This setup, known as a sub-base day tank, requires additional controls to start and stop a fuel transfer pump for refilling.

Sub-base tanks are popular for their compact design and reduced space requirements
Sub-base tanks are a popular choice for many projects due to their compact design and reduced space requirements. They are usually installed outdoors, directly under a single emergency generator, within its own weather-protected enclosure. This design offers a compact and integrated package, eliminating the need for a separate fuel tank. All fuel accessories and piping are pre-installed by the generator manufacturer, reducing permitting and installation costs.
The compact design of sub-base tanks is particularly advantageous for facilities with limited space. By locating the fuel tank beneath the generator, sub-base tanks minimise the overall footprint of the generator system. This makes them ideal for applications where space is at a premium, such as in urban areas or on sites with restricted real estate.
Sub-base tanks also offer flexibility in terms of storage capacity. While they are typically smaller than underground or above-ground tanks, they can be sourced in custom designs with storage capacities of several thousand gallons. However, to avoid EPA registration requirements, they are often specified to store less than 550 gallons. When a longer runtime is required, a supplemental tank can be installed remotely to supply fuel to the sub-base tank on demand.
The reduced space requirements of sub-base tanks also extend beyond their physical dimensions. By housing the fuel tank and generator in a single enclosure, sub-base tanks eliminate the need for additional space to accommodate a separate fuel tank. This can be particularly beneficial for projects where the allocation of space is a critical factor, such as in densely populated areas or on sites with multiple infrastructure components.
In summary, the popularity of sub-base tanks can be largely attributed to their compact design and reduced space requirements. Their ability to integrate the fuel tank and generator into a single enclosure, along with their customisable storage capacities, makes them a versatile and cost-effective solution for a wide range of applications.

Sub-base tanks can be sourced in custom designs with storage capacities of several thousand gallons, but they are often specified to store less than 550 gallons to avoid EPA registration requirements.
In some cases, a sub-base tank may be used in conjunction with a supplemental tank installed remotely, which supplies fuel to the sub-base tank on demand. This setup allows for a longer runtime than what would be possible with a sub-base tank alone. However, it adds complexity as the sub-base tank must now include controls to start and stop a fuel transfer pump to refill it as needed.

Sub-base tanks are commonly used for emergency and standby power generation
When selecting the proper tank for a specific application, it is important to consider the amount of fuel required in case of an emergency or delay in fuel delivery. Storage capabilities are also a factor, as less space correlates with fewer storage possibilities. The stock lead time, or the amount of fuel needed to hold over a business until the next supply arrives, should also be considered. Additionally, the supply lead time, or the time needed to purchase fuel from a vendor, should be taken into account. High-volume purchasing can result in more cost-effective fuel deals and lower shipping costs.

Sub-base tanks are typically smaller than underground or above-ground tanks, making them suitable for storing less than 1,000 gallons of fuel.
Sub-base tanks provide a safe and convenient way to store fuel, ensuring an uninterrupted and reliable power supply. They are built to withstand tough conditions and offer a longer runtime before refuelling is necessary. Additionally, onsite fuel tanks provide immediate access to fuel, making them ideal for emergency situations. Investing in generator fuel tanks is a proactive step in securing a power supply, ensuring preparedness for any situation.
