- Adjusting or reducing non-essential loads
By trimming energy use during critical hours, businesses can avoid hefty demand charges. For example, a manufacturing plant may rely on stored battery power during late afternoons when energy tariffs spike.
What Is Load Shifting?
Load shifting, on the other hand, involves moving energy consumption from high-demand periods to times of lower demand. Rather than reducing total energy use, companies simply reschedule when they consume it.
Practical examples include:
- Running industrial chillers at night when electricity is cheaper
- Charging electric vehicles during off-peak hours
- Pre-cooling commercial buildings before daytime demand increases
Load shifting helps flatten demand curves, which supports grid reliability and can reduce overall operating expenses.
Key Differences: Peak Shaving vs Load Shifting
While both strategies improve efficiency, their focus differs:
| Aspect | Peak Shaving | Load Shifting |
|---|---|---|
| Objective | Reduce usage during peak hours | Move usage to off-peak hours |
| Method | Curtail demand or use stored energy | Reschedule operations |
| Impact | Lowers demand charges | Optimizes energy costs |
| Example | Using BESS at 6 PM peak | Running equipment at midnight |
Benefits of Peak Shaving
- Lower demand charges: Reduces utility costs during peak hours
- Improved resilience: Storage systems can support operations during outages
- Grid stability: Reduces pressure on the network during high demand
Benefits of Load Shifting
