Energy Costs: How Much Will It Cost to Operate?
Operating an above ground storage tank comes with energy costs to consider as part of your cost-benefit analysis. The primary energy expenses stem from heating the tank and fueling the pumps and valves.
Since above ground tanks are exposed to ambient air temperatures, their contents must be heated to remain in a liquid state. The energy required to heat the tank depends on several factors, including:
- The tank’s material and insulation. Steel and aluminum tanks with proper insulation require less energy than concrete or fiberglass tanks.
- The tank’s size and shape. Larger tanks and those with a higher surface area to volume ratio need more energy to heat.
- The stored liquid’s viscosity and freezing point. Substances with a higher viscosity and lower freezing point, such as crude oil, demand more heating than those with a lower viscosity and higher freezing point.
- Ambient temperature conditions. Colder climates necessitate more heating to maintain an adequate internal tank temperature.
- Desired internal temperature. The higher the target temperature, the more energy is needed to reach and sustain it.
Heating costs are often one of the largest operational expenses of above ground tanks, so carefully evaluating these factors can help determine if heating requirements fit within your budget. Alternative heating methods, like heat tracing and insulation jackets, may help reduce costs.
Pumping and Valve Costs
Moving liquids in and out of the tank requires energy to power the pumps, valves, meters, and related equipment. The energy consumption of this equipment depends on the number of components and their efficiency ratings. More frequent loading and unloading also increase associated energy costs. Choosing high-efficiency, properly sized equipment and minimizing excess pumping and valving can help lower energy usage and costs.
Cost vs Utility
When determining if above ground storage tanks are right for your needs, it is important to weigh the costs versus the benefits. While above ground tanks typically have higher upfront costs, they can provide additional utility over time.
The initial purchase and installation of above ground tanks tends to cost more than underground tanks. Above ground tanks require a concrete base and more robust construction to withstand environmental exposure. However, above ground tanks also provide easier monitoring and access for inspections and repairs. Routine maintenance and any necessary repairs can be performed without excavation, reducing ongoing costs.
Above ground tanks may also qualify for additional safety mechanisms like emergency relief vents, foam fire suppression systems or dikes for spill containment. These safety features provide environmental and operational benefits that help avoid unforeseen costs from leaks, spills or other incidents.
Regular maintenance and monitoring of above ground tanks allows for identification of potential issues early on. This can help avoid emergency repairs and limit the impact of any incidents. While underground tanks require specialized monitoring and testing equipment to identify issues, above ground tanks can often be visually inspected.
When evaluating the total cost of ownership, the initial investment in higher quality, safer above ground tanks may provide a strong return on investment over the lifetime of the tanks. The easier access, monitoring and maintenance of above ground tanks helps avoid unplanned costs and limit environmental risks. For many operations, above ground tanks are a cost-effective solution that provides additional utility and peace of mind.
In summary, while above ground storage tanks often come with higher upfront costs, their long-term benefits related to safety, monitoring and maintenance frequently provide a strong return on investment.

Depreciation and Replacement: How Long Do Above Ground Tanks Last?
Above ground storage tanks have a limited lifespan and will eventually need to be replaced. As an asset, the value of an above ground tank depreciates over time. Understanding the rate of depreciation and average replacement timelines can help determine if the initial capital investment in a new tank will provide a good return.
The typical useful life of an above ground tank is 15 to 30 years, depending on factors like material, coatings used, environmental conditions, and frequency of use. Steel tanks tend to last 20-30 years, while fiberglass tanks are on the shorter end of the range. More corrosive substances stored and extreme weather conditions can also reduce tank lifespan.
Above ground tanks depreciate in value over time. The depreciation rate depends on the tank cost, useful life, and salvage value. Using the straight-line depreciation method, if a $50,000 tank has a 20-year useful life and $5,000 salvage value, it would depreciate at $2,250 per year. After 10 years, the tank value would be $25,000. Depreciation reduces tax liability but also means less value to leverage or recover costs.
When it’s time to replace a tank, the total cost will depend on the size, material, and features of the new tank. Installation, permitting, and disposal of the old tank can add 30-50% to the base tank price. If costs have risen with inflation, the replacement tank may be significantly more expensive than the original purchase price, impacting project ROI.
To determine if an above ground tank will provide a good return on investment, evaluate the depreciation rate, expected useful life, replacement cost, and ongoing maintenance requirements. While depreciation reduces tax burden, the eventual replacement cost must still be accounted for to properly assess total lifecycle costs. For high-volume or hazardous material storage, above ground tanks can still prove very cost-effective compared to other options.
