A Comprehensive Guide to Commercial Lithium-ion Containerized Battery Energy Storage Systems
Commercial-level energy storage systems play a crucial role in balancing the grid and ensuring power supply stability. Lithium-ion containerized batteries have become increasingly popular due to their energy density, scalability, and cost-effectiveness. This article delves into the key parameters and costs associated with commercial Li-ion energy storage systems.
Key Parameters of Commercial Li-ion Energy Storage Systems
- Battery Size and Duration: Commercial energy storage systems typically have a rated power of 300 kW and a rated energy storage of 1.20 MWh, providing a 4-hour duration. This means that the system can deliver 300 kW of power for up to 4 hours.
- Battery Size per Container: A 20-ft container can house 1.8 MWh of energy storage, occupying a 15-m2 footprint area. This modular design allows for easy scaling and deployment in various applications.
- Round-trip Efficiency (RTE): The round-trip efficiency of commercial Li-ion energy storage systems is around 90%. This means that 90% of the energy input into the battery can be retrieved and used.
- State of Charge (SOC): Commercial energy storage systems have a minimum SOC of 10% and a maximum SOC of 90%. This affects the usable energy storage rating and ensures battery longevity.
Cost Parameters of Commercial Li-ion Energy Storage Systems
- Li-ion Battery Price: The price of Li-ion batteries for commercial energy storage systems varies based on duration. For a 4-hour system, the price ranges from $157/kWh (MSP Value) to $190/kWh (MMP Value).
- Battery Central Inverter Price: The cost of a bidirectional inverter for commercial energy storage systems is between $0.05/Wac (MSP Value) and $0.06/Wac (MMP Value).
- Battery Cabinet: The battery cabinet, which includes battery packs, containers, thermal management systems, and fire suppression systems, costs between $332/kWh (MSP Value) and $393/kWh (MMP Value) for a 1,200-kWh system.
- Structural BOS: The structural balance of system (BOS) components include foundation and inverter housing. These costs are impacted by the number of inverters and transformers in the system. For a 1,200-kWh system, the costs range between $1,681/m2 (MSP Value) and $1,377/m2 (MMP Value).
