The Imperative for Energy Storage
As the world increasingly transitions to greener energy sources, a significant challenge remains: the intermittency of renewable energy sources such as solar and wind. Unlike traditional fossil fuels, these sources are not always available when demand peaks. Energy storage systems provide a wide array of technological approaches to managing the power supply in order to create a more resilient energy infrastructure and bring cost savings to utilities and consumers. Some of the alternative electrical generation sources, are solar panels, fuel cells, flywheels, wind turbines, batteries, and capacitors be installed and intelligently monitored and controlled to ensure power delivery at all times to the critical loads.
Understanding Battery Energy Storage Systems (BESS)
One dominant energy storage systems Battery Energy Storage Systems (BESS). These systems can store excess energy generated during periods of high production and release it when demand exceeds supply. This capability is not only critical for commercial and residential applications but also plays a crucial role in enhancing the resilience of military installations.
Battery Energy Storage Systems (BESS) are a subset of Energy Storage Systems (ESS) that specifically utilize electro-chemical solutions to store and discharge energy. Unlike general ESS, which can include thermal, electro-mechanical, or other storage technologies, BESS typically relies on advanced battery technologies to manage power supply efficiently. These systems have a broad range of applications, including peak shaving, load shifting, emergency backup, and grid services for commercial users, as well as self-consumption and off-grid solutions for residential users.
Modern battery energy storage systems usually include a built-in inverter and computerized control systems. This means they’re all-in-one, turnkey systems that are simple to install, largely maintenance-free, and don’t require any effort or expertise from the owner. They’re also weatherproof and safe for people and pets.
Characteristics of a Battery Energy Storage System
Round-trip Efficiency — Indicates the amount of usable energy that can be discharged from a storage system relative to the amount of energy that was put in. This accounts for the energy lost during each charge and discharge cycle. Typical values range from 60% to 95%.
Response Time — Amount of time required for a storage system to go from standby mode to full output. This performance criterion is one important indicator of the flexibility of storage as a grid resource relative to alternatives. Most storage systems have a rapid response time, typically less than a minute. Pumped hydroelectric storage and compressed air energy storage tend to be relatively slow as compared with batteries.
Ramp Rate — Ramp rate indicates the rate at which storage power can be varied. A ramp rate for batteries can be faster than 100% variation in one to a few seconds. The ramp rate for pumped hydroelectric storage and for compressed air energy storage is similar to the ramp rate of conventional generation facilities.
Energy Retention or Standby Losses — Energy retention time is the amount of time that a storage system retains its charge. The concept of energy retention is important because of the tendency for some types of storage to self-discharge or to dissipate energy while the storage is not in use.
Energy Density — The amount of energy that can be stored for a given amount of area, volume, or mass. This criterion is important in applications where area is a limiting factor, for example, in an urban substation where space could be a limiting constraint to site energy storage.
Power Density — Power density indicates the amount of power that can be delivered for a given amount of area, volume, or mass. In addition, like energy density, power density varies significantly among storage types. Again, power density is important if area and/or space are limited or if weight is an issue.
Safety — Safety is related to both electricity and to the specific materials and processes involved in storage systems. The chemicals and reactions used in batteries can pose safety or fire concerns.
Life span — measured in cycles.
Depth of Discharge (DoD) — Refers to the amount of the battery’s capacity that has been utilized. It is expressed as a percentage of the battery’s full energy capacity. The deeper a battery’s discharge, the shorter the expected life time. Deep cycle is often defined as 80% or more DoD.
Ambient temperature — Has an important effect on battery performance. High ambient temperatures cause internal reactions to occur, and many batteries lose capacity more rapidly in hotter climates.
Characteristics of BESS
1. Round-Trip Efficiency
Round-trip efficiency refers to the percentage of energy that can be recovered from a BESS compared to the energy that was initially used to charge it. This is a critical metric in determining the system’s overall performance and cost-effectiveness. Modern BESS technologies, particularly lithium-ion systems, offer round-trip efficiencies ranging from 60% to 95%, depending on the specific battery chemistry and configuration. Higher efficiency translates to less energy loss during charging and discharging, making these systems ideal for military installations where energy availability and sustainability are crucial.
2. Response Time
The ability of a BESS to quickly transition from standby mode to full power output is another key feature, particularly in military applications where rapid response to power fluctuations or outages is vital. BESS typically boast rapid response times, often under a minute, making them far superior to traditional backup power solutions like diesel generators or mechanical storage systems. This capability ensures that mission-critical systems remain operational without interruption, even during sudden grid failures or high-demand periods.
3. Ramp Rate
The ramp rate measures how quickly a BESS can adjust its power output, either increasing or decreasing, to match the energy demand. Batteries generally offer faster ramp rates compared to conventional storage technologies like pumped hydro or compressed air energy storage (CAES), allowing them to respond to changes in load or renewable energy fluctuations almost instantaneously. This characteristic is especially beneficial for integrating renewable energy sources, as BESS can stabilize the power supply and mitigate the inherent variability of solar and wind energy.
4. Energy Density and Power Density
Energy density and power density are important characteristics that define how much energy or power can be stored in a BESS relative to its size or weight. High energy density means the system can store more energy per unit of volume, while high power density indicates that it can deliver a significant amount of power in a short period. These qualities are particularly advantageous in space-constrained environments like military bases, naval ships, or mobile installations, where compact, lightweight solutions are essential for operational efficiency.
5. Safety and Lifespan
Safety is a paramount consideration in BESS deployment, particularly for lithium-ion batteries, which are widely used due to their high energy density but also present risks such as thermal runaway and fire. Military applications demand robust safety measures, including fire suppression systems and rigorous monitoring, to mitigate these risks. The lifespan of a BESS is typically measured in charge/discharge cycles, with deeper discharges leading to reduced battery longevity. While technological advances are improving the lifespan of BESS, lifecycle management remains an important factor in optimizing long-term performance and cost. For military installations, selecting the right BESS with appropriate safety features and lifecycle durability is critical for ensuring both energy resilience and operational safety.
Classification of Battery Energy Storage Systems (BESS) by Battery Types
Battery Energy Storage Systems (BESS) rely on various electrochemical solutions, each offering unique advantages tailored to different applications. Here’s a breakdown of the primary battery types used in BESS:
- Lithium-Ion Batteries: Lithium-ion batteries are known for their high energy density, making them an ideal choice for applications requiring compact storage solutions. They boast a long lifecycle with the ability to charge and discharge multiple times without significant degradation. These batteries are widely used in consumer electronics, such as smartphones, laptops, and digital cameras, and are increasingly deployed in electric vehicles and aircraft due to their efficient energy storage capabilities.

- Sodium-Sulfur Batteries: Sodium-sulfur batteries are well-suited for renewable energy storage, particularly for capturing and storing energy from intermittent sources like solar and wind. Their ability to operate at high temperatures and offer large-scale energy storage makes them valuable in renewable energy integration for military microgrids and large installations.
- Zinc-Bromine Batteries: Similar to sodium-sulfur batteries, zinc-bromine batteries are also used to store renewable energy. They are designed for large-scale energy storage, offering long discharge durations, which is essential for stabilizing the grid when renewable sources fluctuate. Their utility in military bases or remote installations helps ensure continuous power availability, even during renewable energy shortfalls.
- Flow Batteries: A flow battery is a type of rechargeable battery where rechargeability is provided by two chemical components dissolved in liquids contained within the system and most commonly separated by a membrane. This technology is akin to both a fuel cell and a battery – where liquid energy sources are tapped to create electricity and are able to be recharged within the same system. One of the biggest advantages of flow batteries is that they can be almost instantly recharged by replacing the electrolyte liquid, while simultaneously recovering the spent material for re-energization. Different classes of flow cells (batteries) have been developed, including redox, hybrid and membraneless. The fundamental difference between conventional batteries and flow cells is that energy is stored as the electrode material in conventional batteries but as the electrolyte in flow cells. Flow batteries, including vanadium redox flow and zinc-bromine flow variants, are known for their scalability and durability. They are generally used to store large amounts of energy from renewable sources like wind and solar. Flow batteries have the advantage of being able to separate energy capacity from power output, allowing them to be tailored to specific needs. Due to their size, they are typically used in grid-scale or microgrid applications where space and flexibility allow for larger installations.
Each battery type offers distinct benefits, catering to a range of military and commercial needs, from portable energy storage solutions to massive grid-scale applications for renewable energy integration and emergency power.
Key Benefits of Battery Energy Storage Systems (BESS)
Battery energy storage systems are rechargeable battery systems that store energy from solar arrays or the electric grid and provide that energy to a home or business. Because they contain advanced technology that regular batteries do not, they can easily perform certain tasks that used to be difficult or impossible, such as peak shaving and load shifting.
1. Peak Shaving
One of the most significant benefits of BESS is its ability to perform peak shaving, which reduces electricity costs by minimizing the amount of power drawn from the grid during periods of peak demand. During peak hours, electricity prices are often higher due to the strain on the grid caused by increased consumption. BESS can be charged during off-peak hours when energy is cheaper and then discharged to meet demand during peak times. This not only leads to substantial cost savings for facilities but also alleviates stress on the grid, reducing the likelihood of outages or the need for additional, expensive peak power plants.
For businesses on demand charge utility tariffs, between 30% and 70% of the utility bill may be made up of demand charges. Solar arrays alone aren’t always a sufficient solution for these businesses. Battery energy storage systems, however, can guarantee that no power above a predetermined threshold will be drawn from the grid during peak times. For military installations, this capability is particularly beneficial as it enables more predictable energy expenditures and decreases dependence on volatile energy markets.
2. Load Shifting
Load shifting is another essential function of BESS that optimizes energy consumption patterns. Battery energy storage systems allow businesses to shift energy usage by charging batteries with solar energy or when electricity is cheapest and discharging batteries when it’s more expensive. By charging batteries during off-peak times, such as at night or when solar and wind energy production is at its highest, and then discharging the stored energy during periods of high electricity demand, BESS helps smooth out energy usage over time.
This allows military bases and commercial enterprises to make better use of renewable energy sources and avoid the higher costs associated with peak electricity usage. Additionally, in regions with time-of-use pricing structures, load shifting can lead to significant financial savings, allowing organizations to strategically use electricity when it is least expensive. For military applications, load shifting not only improves cost-efficiency but also enhances energy management by aligning energy consumption with mission-critical needs.
3. Emergency Backup
One of the most critical functions of BESS is to serve as an emergency backup during grid outages. In military contexts, continuous power is essential for maintaining communication, security, and operational systems. BESS provides a reliable power source during unexpected outages, ensuring that critical operations remain uninterrupted. Unlike traditional diesel generators, which require fuel and maintenance, battery systems can instantly provide power without the need for manual intervention or fuel logistics. This capability is invaluable for military installations located in remote or hostile environments where grid reliability may be compromised. Emergency backup through BESS ensures that essential systems remain operational, protecting national security and mission readiness.
4. Renewable Integration
As military installations and commercial enterprises move toward greener energy solutions, the ability of BESS to enhance renewable energy integration becomes increasingly important. Solar and wind power generation are inherently intermittent, which can lead to periods of excess energy production followed by periods of insufficient supply.Solar produces cyclically – day vs. night, summer vs. winter.
BESS addresses this issue by storing surplus energy produced during peak renewable generation times and discharging it when production is low. This helps smooth the output from renewable energy sources, making their performance more consistent and reliable. For military bases that are incorporating renewable energy into their infrastructure, BESS ensures that solar or wind energy can be relied upon around the clock, reducing reliance on the grid or fossil fuels while enhancing sustainability and operational resilience.
5. Grid and Microgrid Services
Beyond direct power storage and supply, BESS provides valuable grid services, such as frequency regulation, voltage support, and reserve power, all of which contribute to the overall stability of the grid. Frequency regulation ensures that the power supply stays within a specified range, which is crucial for preventing blackouts and maintaining the performance of sensitive military equipment. Voltage control helps balance the grid’s voltage levels, preventing fluctuations that could damage infrastructure or disrupt operations. Moreover, BESS can provide reserve power, which can be quickly dispatched during grid failures or energy shortages. For military installations, these grid services not only
Microgrids — Energy storage enables the creation of resilient, self-sustaining microgrids when paired with renewable energy. The scalability and ease of deployment of battery energy storage systems make these microgrids both economically viable and efficient. Islandable microgrids, such as the one on American Samoa’s island of Ta’u, which transitioned from diesel to solar plus storage, demonstrate the potential for communities and large commercial facilities to achieve energy independence.
BESS has advantage over other Storage technologies as it has small footprint and no restrictions on on geographical locations that it could be located in. Other Storage technologies like Pumped hydro storage (PHS) and Compressed air energy storage (CAES) are only suitable for limited number of locations, considering water and siting-related restrictions and transmission constraints. Accordingly BESS utilizing Lithium Ion technology offer high energy and power densities that are suitable for utilizing at distribution transformer level. The available space at the distribution transformer setup can be used to locate the BESS.
How BESS Enhances Power Resilience

These case studies highlight how BESS can directly contribute to the operational effectiveness of military installations and maritime fleets, offering both energy security and environmental benefits.
Risks Involved in Using BESS
While Battery Energy Storage Systems (BESS) are transforming energy storage and resilience for military and commercial applications, they come with significant risks due to their size, complexity, and energy density—particularly in systems using lithium-ion (Li-ion) battery chemistry. The following outlines the key risks associated with BESS:
- Thermal RunawayThe primary risk with Li-ion batteries is thermal runaway, a dangerous cycle where excessive heat generates even more heat. This phenomenon can occur due to internal cell defects, mechanical failures, damage, or overvoltage. As heat accumulates, it causes gas buildup, which can lead to the explosive rupture of battery cells. In a worst-case scenario, thermal runaway can spread from one cell to the next, causing a chain reaction that results in fires or explosions. The risk is especially high in large-scale installations where the failure of one battery could compromise an entire system if proper safety mechanisms are not in place.
- Challenges in Extinguishing Battery FiresBattery fires, especially in Li-ion systems, are notoriously difficult to extinguish. These fires can burn at extremely high temperatures and may reignite even after being seemingly extinguished. Unlike conventional fires, battery fires require specialized firefighting techniques, and it can take days or even weeks to fully control a blaze. This poses serious risks in environments where rapid response to emergencies is critical, such as military bases or critical infrastructure.
- Failure of Protection and Control SystemsThe reliability of Battery Management Systems (BMS) is crucial in preventing accidents. A failure in these systems can result in overcharging or the inability to monitor critical parameters like temperature, cell voltage, and state of charge. A BMS malfunction increases the risk of overheating, leading to thermal runaway or electrical faults. Ensuring robust and redundant control systems is essential to mitigate these risks.
- Sensitivity to Mechanical Damage and Electrical TransientsLi-ion batteries are particularly vulnerable to mechanical damage and electrical surges, which can cause internal short circuits. Even minor damage to the battery’s casing or internal components can lead to overheating, which might escalate into battery explosions or fires. Once a battery is compromised, it can cause a chain reaction that affects adjacent cells, resulting in a larger-scale fire or system failure. The sensitivity to electrical transients like voltage spikes adds another layer of complexity to ensuring safe operation.
To manage these risks, industries are increasingly investing in advanced fire suppression systems, enhanced BMS technology, and thermal management techniques to prevent overheating. Additionally, battery enclosures designed to contain thermal runaway and prevent fire spread are being developed for large-scale installations. However, given the critical nature of BESS applications in military and defense contexts, continued innovation and stringent safety standards are crucial for ensuring safe and reliable energy storage.
