What are Commercial Battery Storage Systems?
Commercial battery storage systems are large-scale energy storage solutions, akin to big power banks, designed to store and release electricity from various sources. These systems vary in size and capacity, ranging from 50 kWh to 1 MWh, making them suitable for small- to medium-sized organizations.
With a modular structure, these systems can be customized to meet specific applications and customer needs. They are widely used in facilities like schools, hospitals, petrol stations, shops, and industries to manage energy requirements effectively.
Commercial battery storage systems help support the grid by balancing demand fluctuations, providing backup power during outages, and integrating with renewable energy sources like wind and solar. They can also reduce electricity bills and create new revenue opportunities, making them a cost-effective solution for many businesses.
Advantages of Commercial Energy Storage Systems
- Resiliency: These systems provide backup power during grid failures or other emergencies, ensuring continuous operation for critical facilities like hospitals, data centers, and industries that cannot afford power interruptions.
- Cost Savings: Commercial energy storage systems help businesses lower electricity costs by shifting usage from peak to off-peak hours when power is cheaper. This reduces demand charges based on the highest electricity usage during a billing period. Additionally, businesses can earn revenue through demand response programs that reward reduced electricity use during peak times.
- Renewable Integration: These systems enhance the use of renewable energy sources like solar and wind by storing excess power during high generation periods and releasing it during low generation periods. This reduces reliance on fossil fuels and lowers greenhouse gas emissions. They also stabilize the grid by balancing supply and demand and providing services like frequency control and voltage support.
- Additional Grid Benefits: Commercial energy storage systems improve grid and societal resilience against cyberattacks and natural disasters, boost economic value and competitiveness by creating new jobs and markets, and reduce environmental impact by lowering air pollution and water consumption.

Components of Commercial Energy Storage Systems
- Battery System: The heart of commercial energy storage, composed of cells that convert chemical energy to electrical energy. Cells are arranged in modules, racks, and strings, connected in series or parallel to achieve the desired voltage and capacity. Lithium-ion is the preferred chemistry.
- Battery Management System (BMS): Monitors and ensures the safety, longevity, and efficiency of the battery system by regulating voltage, temperature, current, state of charge, and health. It also manages the cooling system and cell balance.
- Inverter or Power Conversion System (PCS): Converts the battery’s DC output to the AC needed by the grid or load. It regulates voltage, frequency, and power quality and can be configured as AC-coupled or DC-coupled based on system design.
- Energy Management System (EMS): Manages energy flow according to user needs and preferences, communicating with the grid, load, and other power sources like solar and wind. It handles tasks such as peak shaving, load shifting, frequency control, backup power, and energy arbitrage.
Lithium Ion Batteries
The high efficiency of the energy storage system is guaranteed by the advanced battery technology and the integrated BMS. The lithium battery has a reduced environmental impact combined with excellent performance and safety. The ideal battery bank for the project is defined according to the type of application, storage capacity, charging/discharging capacity, service life, etc. Lithium batteries are used because they provide several advantages in relation to the other topologies used worldwide – among them, high energy density, extended useful life, high charging and discharging capacity, modularity and low maintenance.
The figure below shows the modularity of these batteries; the cells are enclosed in modules and mounted on racks. Each rack has its energy measurement, control and management unit (BMS).

Connecting Commercial Battery Storage Systems with Photovoltaics
Yes, commercial battery storage systems can be connected with photovoltaics (PV) to create a solar-plus-storage system. This configuration allows you to store excess solar energy generated during the day and use it at night or during grid outages. It enhances solar power self-consumption and reliability while reducing demand costs and grid fees.
A solar-plus-storage system can also participate in energy markets, offering grid services like frequency management, voltage support, demand response, and energy arbitrage. This makes it a financially viable and environmentally responsible option for businesses.
