Industrial and commercial energy storage refers to storage systems installed on the side of industrial and commercial users, while containerized storage mainly refers to storage facilities on the generation and grid side. These two types differ in design concept, application scenarios, scale, cost, installation, and deployment, with each having its own focus. Additionally, with the rapid growth of the energy storage market, solar plus storage is poised to become the largest demand market globally. Below is a detailed comparison of the two:
Design Concept:
Industrial and commercial energy storage systems are designed to help commercial and industrial users optimize energy usage, reduce energy costs, and enhance energy reliability. These systems are typically custom-tailored to meet the specific needs of users, ensuring seamless integration with existing power systems and operational processes.
Containerized energy storage systems are known for their modularity, mobility, and rapid deployment. These systems are usually pre-installed in standard-sized containers, allowing for quick transportation to locations requiring power storage.
Application Scenarios:
Industrial and commercial energy storage systems are commonly found in manufacturing, data centers, large shopping malls, hospitals, and other places with strict requirements for power quality and reliability.
Containerized energy storage systems are suitable for scenarios requiring rapid deployment of energy storage, such as temporary facilities, remote areas, disaster recovery sites, or as auxiliary systems for the grid to balance supply and demand.
Scale:
Industrial and commercial energy storage systems vary greatly in scale, ranging from tens of kilowatts (kW) to several megawatts (MW). For example, a medium-sized factory may require a 1MW energy storage system for peak shaving, while a large data center may need a 5MW or larger system to ensure uninterrupted power supply.
Containerized energy storage systems are more standardized in scale, with each container typically having a capacity ranging from hundreds of kilowatts to several megawatts. For instance, a standard 20-foot container can accommodate 1MW of storage capacity.
Cost:
Industrial and commercial energy storage: The cost of custom-designed industrial and commercial energy storage systems is relatively high in terms of design, installation, and maintenance. Depending on the complexity and scale of the system, initial investment may range from hundreds of thousands to millions of dollars.
Containerized energy storage: Due to standardization and mass production, the cost of containerized energy storage systems is generally lower than custom-designed industrial and commercial systems. Prefabricated containerized energy storage units may cost a few hundred dollars per kilowatt-hour, while the overall project cost depends on the required capacity and functionality.
Installation and Deployment:
Industrial and commercial energy storage typically requires professional design and installation, which may involve retrofitting existing power infrastructure and configuring interactions with the grid. Installation periods can range from several months to a year, depending on the project's scale and complexity.
Installation of containerized energy storage systems is usually very rapid and can be completed within days to weeks. The modular design of the systems makes capacity expansion simple, requiring only the addition of more container units.
Summary:
Industrial and commercial energy storage and containerized energy storage have their advantages and characteristics in design concept, application scenarios, scale, cost, installation, and deployment. Industrial and commercial energy storage focuses more on customization and integration with existing user facilities, while containerized energy storage emphasizes standardization, mobility, and rapid deployment.
When selecting an energy storage system, users need to consider their specific requirements, budget, and project urgency to determine the most suitable solution.
