- Charge the ESS with power during the off-peak hours when electricity rates are lowest
- Discharge during peak hours when electricity rates are highest
- Additional discharge during mid-peak hours if there is excess capacity
- Reduce basic charges through peak load management
- Reduce electricity usage charges through demand management
- Reduce additional fees due to reduced usage charges
- Achieve a minimum of 20% reduction compared to existing electricity basic charges
- Serve as an emergency power supply during outages
