Practical Benefits of a BESS for Business

The system is designed to provide uninterrupted power for critical business loads. The BESS has a power rating of 125 kW and a usable battery capacity of 234 kWh. The actual backup duration depends on the facility’s load.

Backup Power for Critical Loads

In the event of a grid outage, the BESS supplies power to selected critical business loads.

125 kW BESS power

The actual equipment to be backed up is determined based on the facility’s load.

Fast Transfer to Backup Power

The system automatically switches to backup power when the external grid goes down.

Economic Impact of the BESS

System payback:

Calculated individually

Depends on:

operating mode and load profile

Savings Depend on the Use Case

The economic effect of a BESS depends on the frequency and duration of power outages, the cost of downtime, the facility’s load profile, and how the system is used. The exact payback period is calculated individually after analyzing the facility.
