Whether you're a business owner seeking renewable energy solutions, an industry expert staying up-to-date with the latest advancements, or simply an enthusiast curious about the future of sustainable technology, this article aims to provide valuable insights. Let's start our exploration by diving right into these common questions.
A commercial battery storage system is a clean technology designed to store electrical energy for use at a later time. These systems serve as the backbone of a business's energy infrastructure, providing the ability to store electricity when demand is low and dispatch it when demand is high. This ability to control when and how electricity is used provides a significant advantage, allowing businesses to operate more efficiently and sustainably.
Commercial battery storage systems utilize advanced battery technologies, which are installed on a business's premises. The stored energy can be derived from various sources, including the grid during off-peak times or from renewable energy installations such as solar panels or wind turbines. Once stored, this energy can be used in several ways: it can be dispatched during peak demand times to reduce energy costs, used as a backup power source during outages, or even fed back into the grid in certain scenarios.
Commercial battery storage systems are not just about energy independence—they are also about smart energy management. These systems can be programmed to optimize energy use based on various factors, such as energy prices, peak demand times, and the business's specific energy needs. In essence, a commercial battery storage system allows businesses to take control of their energy use, improving efficiency, reducing costs, and supporting sustainability efforts.
Exro Technologies' 90kW/192kWh Cell Driver™ is a prime example of this technology, offering businesses a reliable and efficient solution for managing their energy needs while supporting the transition to renewable energy sources.
Commercial battery storage systems work by capturing and storing electrical energy, and then providing that energy when it's needed. This process involves several stages:
Charging: The first step is charging the system. This involves taking electricity from a source—whether it's from the grid or from a renewable energy system like solar panels or wind turbines—and storing it in the system's batteries. The energy is often stored in the form of chemical energy within these batteries, ready to be converted back into electrical energy when needed.
Storing: Once charged, the energy is stored until it's needed. Advanced battery technologies used in these systems can hold a substantial amount of energy for extended periods. This stored energy can be used at any time, providing flexibility in managing energy demands.
Discharging: When energy is required—for instance, during peak demand times, during a power outage, or when renewable sources aren't producing energy—the system discharges, converting the stored chemical energy back into electrical energy and delivering it where it's needed.
Managing: Most commercial energy storage systems also have a management component. This is typically a computer system that manages the flow of energy, deciding when to charge and discharge based on various factors like energy prices, demand patterns, and the overall energy needs of the business.
Exro Technologies' Cell Driver™ is equipped with an advanced Energy Management System that dynamically and intelligently manages the system. It's designed to efficiently manage energy use, storing power when demand and prices are low and supplying it when demand is high or during power outages. The result is a more reliable, efficient, and cost-effective approach to managing a business's energy needs.
Commercial battery storage systems offer numerous benefits to businesses, making them an increasingly popular choice in today's energy landscape. Here are some of the main advantages:
Energy Cost Savings: By charging during off-peak times when energy prices are lower and discharging during peak demand times when prices are higher, these systems can generate significant cost savings. This practice, known as load shifting or peak shaving, can dramatically reduce a business's energy bill.
Demand Charge Management: Businesses often face demand charges based on their highest peak energy usage. With battery storage systems, businesses can draw power from their storage system during periods of peak demand, effectively reducing peak grid energy usage and associated demand charges.
Resilience and Reliability: Commercial battery storage systems can provide backup power during grid outages, ensuring uninterrupted operations. This is crucial for businesses that rely on constant power supply, such as refrigerated facilities, hospitals, and manufacturing facilities.
Support for Renewable Energy: These systems are an ideal complement to renewable energy sources like solar and wind. They can store excess energy produced during peak production times for use when production is low or non-existent, such as at night for solar power.
EV Charging Buffer: As electric vehicle (EV) use increases, so does the demand for charging stations. Commercial battery storage can help manage the load of EV charging stations by storing power during low-demand periods and supplying it during times of high demand, preventing overloads and maintaining a stable power supply.
Reduced Carbon Footprint: By optimizing energy usage and enabling the effective use of renewables, commercial battery storage systems can help businesses reduce their carbon footprint and contribute to sustainability goals.
Grid Services: In some cases, businesses with commercial battery storage systems can participate in demand response programs or provide other grid services, which can generate additional revenue or savings.
Exro Technologies' Cell Driver™ embodies these benefits, offering an efficient and reliable solution for commercial energy management. By using the Cell Driver™ system, businesses can optimize their energy usage, support their sustainability goals, and ensure they have reliable power when they need it most.
The amount of energy a commercial energy storage system can store varies widely based on the specific system and its configuration. It's typically measured in kilowatt-hours (kWh), a unit of energy that represents the amount of work that can be done by one kilowatt of power in one hour.
Smaller commercial battery storage systems might have a capacity of a few dozen kilowatt-hours, suitable for small businesses or facilities. Larger systems, designed for bigger operations or industrial use, can store hundreds or even thousands of kilowatt-hours. The capacity needed will depend on the energy needs of the business, the variability of their energy supply and demand, and their goals for using the system, such as backup power provision or cost savings.
For instance, Exro Technologies' Cell Driver™ has a capacity of 192 kilowatt-hours. This substantial capacity makes it suitable for a wide range of commercial applications, providing ample energy storage for businesses to manage their energy use effectively, support renewable energy integration, and ensure reliability and resilience of their power supply.
The duration of energy storage in commercial systems largely depends on the technology and design of the system. While most modern battery storage systems are designed for daily energy cycling—charging during periods of low demand or high renewable energy production and discharging during high demand or low production periods—they can theoretically hold their charge for a longer duration if left unused.
For instance, lithium-ion battery packs, a common technology in commercial battery storage systems, can retain most of their charge for an extended period. In favourable conditions, they lose only around 2 to 3 percent of their charge per month when left unused.
However, it's important to note that the optimal use of these systems isn't to store energy indefinitely. They are designed to actively manage energy supply and demand, which involves regular charging and discharging.
The lifecycle of these systems, on the other hand, can vary based on numerous factors, including the quality of the components, the management of the charge and discharge cycles, environmental conditions, and the level of maintenance. Generally, a well-maintained commercial energy storage system can have a lifetime of 10 to 20 years.
Exro Technologies' Cell Driver™ provides a stellar example of this technology at work. Unlike other systems, the Cell Driver™ is equipped with a patented Battery Control System™ (BCS). This advanced technology actively manages each individual cell within the system, monitoring its state of charge and state of health. This means the system can intelligently decide which cells to use at any given moment, allowing certain cells to rest when they're not needed - enhancing the overall safety and performance of the system.

By allowing the optimal utilization and rest of individual cells, the Battery Control System™ ensures that the Cell Driver™ can provide reliable and efficient energy management over an extended period, making it an ideal long-term solution for businesses while also enabling the use of second-life EV and telecommunication batteries.
Battery storage plays a crucial role in our transition to a more sustainable energy landscape, but it's important to understand the distinctions between commercial battery storage, grid-scale storage, and residential storage. These systems differ not only in scale and capacity but also in the permits, certifications, and installation considerations they require.
Grid-Scale Battery Storage: Grid-scale storage, also known as utility-scale storage, refers to energy storage systems deployed on a larger scale to support the overall electrical grid. These systems are typically located at centralized facilities and provide significant energy storage capacity to stabilize the grid, manage peak demand, and facilitate the integration of renewable energy sources effectively. Grid-scale storage projects involve large battery arrays, pumped hydro storage, compressed air energy storage, or other technologies capable of storing and discharging large amounts of energy. Due to the magnitude of these installations and their impact on the grid, they require comprehensive permits, regulatory approvals, and grid interconnection agreements.
Commercial Energy Storage: Commercial energy storage systems are specifically designed for businesses, industries, and commercial facilities. These systems have lower capacity than grid-scale energy storage but higher capacity than residential systems. Commercial energy storage solutions offer tailored features, such as demand charge management, load shifting, and backup power capabilities, to optimize energy usage, reduce costs, and enhance energy reliability for commercial and industrial settings. They require specific permits and certifications for commercial installations and may not be suitable or approved for use in residential zones due to regulatory requirements.
Residential Storage: Residential storage solutions are designed for individual homes and smaller-scale energy needs. These systems are typically installed within or near residential properties and enable homeowners to optimize their energy usage, increase self-consumption of renewable energy, and provide backup power during outages. Residential storage solutions, such as lithium-ion battery units, are smaller in scale and capacity compared to commercial or grid-scale systems. They require permits and certifications specific to residential installations, ensuring compliance with safety regulations and grid interconnection standards.
Furthermore, it's important to understand the concept of "behind the meter" and "in front of the meter" installations. Commercial and residential energy storage systems are often considered "behind the meter" installations, as they are located on the customer's side of the utility meter. These systems primarily serve the energy needs of the customer and can reduce reliance on the grid. In contrast, grid-scale storage installations are typically considered "in front of the meter" as they are connected directly to the grid and provide services to the larger electrical system.
Each type of energy storage system requires specific permits, certifications, and regulatory compliance to ensure safe and reliable operation. Understanding these differences and associated considerations helps businesses and homeowners select the appropriate system for their needs while adhering to local regulations and utility requirements.

The world’s need for electricity keeps growing. Businesses today rely on a steady, clean power supply more than ever. Think about factories, big stores, or even your local office building. They all need reliable energy to run well. As we use more green energy sources, like solar panels and wind turbines, a big question comes up: how do we keep power flowing when the sun isn’t shining or the wind stops?
This is where commercial battery energy storage systems (BESS) step in. Simply put, these systems are large batteries for businesses. They store extra electricity when it’s cheap or when renewable sources are making a lot of power. Then, they release that power when the business needs it most, or when grid electricity gets expensive. These systems work with traditional power, making the whole system stronger.
This guide will walk you through everything about commercial BESS. You will learn what makes them tick, how they help businesses save money, and where they are used. We’ll also look at what to think about before getting one, and what the future holds for this important technology.
To really get how a commercial battery system works, you need to know its main parts. It’s more than just a big battery. Many smart pieces work together to store and deliver power safely and well. These parts ensure the system runs smoothly every day.
The type of battery inside the system matters a lot. Each kind has its own strengths and weaknesses. Choosing the right one depends on what the business needs.
• Lithium-ion Batteries: These are the most common choice for commercial use. Why? They pack a lot of power into a small space. They also last a long time, often many years. Costs for these batteries have dropped quite a bit lately, making them a top pick. Two main types are popular: LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt). LFP batteries are known for being very safe and having a long cycle life. NMC batteries offer higher energy density, meaning they can store more power in the same size.
• Other Chemistries: While lithium-ion leads, other battery types are gaining notice. Flow batteries, like Vanadium Redox Flow, store energy in liquid tanks. They are great for very long periods of storage, sometimes for many hours. They may not be as compact as lithium-ion, but they can be a good fit for certain long-duration needs. New chemistries are always being researched too.
Batteries can’t work alone. They need a team of other parts to make sure they run safely and give power just right. These helper components are super important. They keep everything in check.

• Inverters and Converters: Imagine electricity flowing like water. Batteries store power as DC (direct current). But your building and the grid use AC (alternating current). Inverters change the DC power from the battery into AC power your building can use. They also do the opposite, turning AC power from the grid into DC to charge the battery. These devices are key for managing power flow.
• Battery Management System (BMS): This is like the brain of the battery system. The BMS constantly watches each battery cell. It checks things like how much charge is left and the temperature. It keeps batteries from getting too full or too empty. This protects the batteries, making them last longer and keeping everyone safe. A good BMS is truly vital for long-term health.
• Thermal Management Systems: Batteries work best within a certain temperature range. If they get too hot or too cold, they don’t last as long and might even be unsafe. Thermal systems, like cooling fans or heaters, keep the battery at its ideal temperature. This makes sure the batteries give their best power for many years.
Getting a BESS to work with your building and the wider electricity grid needs smart hook-ups. These systems make sure the battery knows what to do and when to do it. It’s all about smart communication.
• Grid Interconnection: Connecting a BESS to the main power grid involves following strict rules. These rules make sure the system is safe for workers and for the grid itself. Proper hook-ups prevent problems and keep the power flowing smoothly. Local utilities have specific guidelines for this step.
• Energy Management Software (EMS): This software is the master planner. It tells the BESS when to charge up and when to let power out. The EMS looks at many things. It checks how much power your business is using. It also watches electricity prices, charging more when power is cheap. The EMS makes sure the BESS always works in the smartest way to save money.
Businesses that use BESS find many good things come from it. These systems are not just about being green. They offer real, clear benefits that help the bottom line and keep operations running. Let’s look at some big wins.
A stable power grid is a strong grid. Commercial BESS can act like shock absorbers for the electricity system. They help make sure power is always there, even when things get tricky.
• Peak Shaving and Load Leveling: Imagine your electricity bill jumps up when you use a lot of power at one time. This is called a demand charge. BESS helps by using stored power during these busy times. It lowers the amount of power you pull from the grid. This smooths out your energy use and cuts those high demand charges. It’s like having your own power reserve.
• Ancillary Services: BESS can do more than just power your building. They can also help the main grid. For example, they can quickly add or remove power to keep the grid’s frequency steady. This service helps the grid operator keep things running well. Sometimes, businesses can even earn money for providing these critical services.
• Backup Power and Resilience: What happens if the power goes out? For many businesses, even a short outage can mean big losses. A BESS can instantly switch on and give your building power. It keeps important machines running and lights on. This makes your business much tougher against power cuts.
Money talks, and BESS systems offer clear financial gains. Businesses can see real savings on their energy bills. They can also create new ways to earn cash.
• Reduced Electricity Costs: The biggest financial benefit often comes from cutting electricity bills. By using stored energy during peak times, businesses avoid buying expensive power from the grid. They can also charge batteries when power is cheap (like at night) and use it when power is costly (like during the day). This is called time-of-use arbitrage.
• Revenue Generation: Beyond saving money, BESS can help businesses make money. How? By joining demand response programs. In these programs, the utility pays you to reduce your power use when the grid is stressed. Also, as mentioned, providing ancillary services can bring in extra cash.
• Potential for Energy Independence: Pair a BESS with solar panels on your roof, and you start to become your own power plant. This means less reliance on the grid. You get more control over your energy costs. This helps protect your business from sudden price hikes or power problems.
Renewable energy is the future, but it has one challenge: it’s not always on. The sun doesn’t shine at night, and the wind doesn’t always blow. BESS solves this problem beautifully.
• Smoothing Renewable Output: When solar panels make too much power, a BESS can store that extra energy. When the panels aren’t making enough, the BESS releases the stored power. This makes renewable energy sources much more reliable. It ensures a constant stream of clean power, day or night.
• Increasing Renewable Penetration: With storage, grids can handle more solar and wind power. Without it, too much renewable energy could make the grid unstable. BESS acts as a buffer. It allows more clean energy to be added to the grid without causing problems. This is key for a greener energy future.
