A Commercial & Industrial Energy Storage System (ESS) is a high-capacity battery solution designed to supply backup and peak-shaving power for factories, warehouses, data centers, and commercial buildings. Unlike diesel generators, ESS provides instant power without noise, fuel consumption, or exhaust emissions.

Most industrial ESS solutions utilize Lithium Iron Phosphate (LFP) battery technology, known for:

• High safety and thermal stability

• Long operational lifespan

• High charge-discharge efficiency

Dagong ESS provides modular commercial and industrial ESS options, including:

• 241kWh Air-Cooled ESS – Ideal for medium-sized commercial facilities.

• 372kWh Liquid-Cooled ESS – High-capacity solution for industrial loads.

• 5MWh Air-Cooled Container ESS – Scalable containerized solution for large-scale industrial operations.

Types of Industrial ESS

Depending on application and load requirements, industrial ESS can be deployed as:

• Air-Cooled Systems (100–241kWh) – Cost-effective and simple installation for mid-size facilities.

• Liquid-Cooled Systems (215–372kWh) – Advanced thermal management for high-load industrial equipment.

• Containerized ESS (3–5MWh) – Fully modular container systems for large commercial or industrial operations.

Dagong ESS systems support hybrid integration with solar PV, wind energy, and microgrids, providing businesses with flexibility, clean energy, and cost optimization.

Why Diesel Generators Are Being Replaced in Commercial & Industrial Settings

Diesel generators have been widely used for backup power in industrial and commercial facilities, but they come with notable disadvantages:

• High operational costs due to fuel consumption and frequent maintenance

• Noise pollution affecting workplace comfort and safety

• Emissions that may conflict with ESG and sustainability goals

• Limited automation and delayed response during outages

Industrial and commercial operators increasingly adopt LFP ESS to reduce reliance on diesel, minimize costs, and comply with environmental regulations.

Features of Commercial & Industrial ESS

Commercial and industrial energy storage systems offer:

• High Power Density and Instant Response: Supports critical loads with zero interruption.

• Long Service Life: Over 8000 cycles, lasting 15+ years.

• Scalable & Modular Design: Expandable to multi-MWh capacity for large facilities.

• Smart Energy Management: Real-time monitoring, load control, and predictive maintenance.

• Hybrid Operation: Seamless integration with renewable energy sources and grid support.

For example, a Dagong ESS 5MWh Air-Cooled Container can power an entire industrial plant or warehouse for several hours without any diesel usage.

Applications of Industrial ESS

Commercial & Industrial ESS can support:

• Peak Shaving & Demand Charge Reduction: Minimize electricity costs in commercial buildings.

• Critical Backup Power: Data centers, manufacturing equipment, and warehouses remain operational during grid failures.

• Renewable Energy Integration: Store excess solar or wind energy for on-demand usage.

• Microgrid & Off-Grid Operations: Ensure energy reliability in remote or industrial campuses.

Replacing diesel generators with energy storage systems provides businesses with cleaner power, reduced operational risk, and greater flexibility for future energy planning.

Price of Industrial ESS

The price of industrial energy storage depends on capacity, cooling type, and integration complexity.

• 241kWh Air-Cooled ESS – Efficient for medium facilities.

• 372kWh Liquid-Cooled ESS – High-load industrial support.

• 5MWh Container ESS – Large-scale applications for factories or commercial parks.

While initial investment may exceed diesel generators, long-term savings from fuel-free operation, minimal maintenance, and extended lifespan make ESS a cost-effective solution.

How to Select the Right Commercial or Industrial ESS

Key factors to consider include:

• Total facility load and backup duration

• Available installation space

• Integration with renewable energy sources

• Budget and operational cost targets

Dagong ESS engineers provide customized turnkey solutions, including system design, installation, control, and after-sales support, ensuring seamless adoption for commercial and industrial users.
