The cost differences between residential and utility-scale battery storage systems are primarily driven by factors such as scale, technology, and application use cases.
Residential Battery Storage Systems
- Cost Range: For home systems, costs typically vary from about $200 to $600 per kWh, depending on the brand, technology, and installation specifics.
- Application: Residential systems are often used to support rooftop solar systems, providing backup power and grid stability.
- Size and Scope: These systems are much smaller, often ranging from a few kWh to tens of kWh.
- Economies of Scale: Due to their smaller size, residential systems benefit less from economies of scale compared to utility-scale systems.
Utility-Scale Battery Storage Systems
- Cost Range: The cost for utility-scale systems, such as lithium-ion batteries, ranges from approximately $100 to $300 per kWh for large-scale applications. By 2030, costs are projected to be between $159/kWh and $348/kWh.
- Application: Used for grid stabilization, peak shaving, and integrating renewable energy sources.
- Size and Scope: Much larger, often in the range of megawatt-hours (MWh) or even gigawatt-hours (GWh), which allows for greater economies of scale.
- Economies of Scale: Utility-scale systems benefit significantly from economies of scale, with lower costs per kWh compared to residential systems.
Key Cost Components
| Component | Residential | Utility-Scale |
|---|---|---|
| Battery Cost | $200-$600/kWh | $100-$300/kWh |
| System Size | A few kWh to tens of kWh | MWh to GWh |
| Economies of Scale | Limited | Significant |
In summary, utility-scale battery storage systems generally offer lower costs per kWh due to larger scale and economies of scale, while residential systems are pricier but tailored for individual home needs.
