3. FEMS App Peak Shaving
While private customers only pay the pure "working price" for their electricity consumption, i. e. a price per kWh, industrial customers also pay a performance price. This results from the maximum measured output during a month or a year and can amount to a significant proportion of the electricity costs. Here, the "FEMS App Peak Shaving" offers help.
As soon as the "FEMS App Peak Shaving" has been activated on your FEMS, you will see this widget in your monitoring:

- Measured value
-
The power currently measured at the grid connection point in [kW].
- Discharge above
-
The configured "Peak Shaving power" in [kW].
- Charging below
-
The configured "Recharging Power" in [kW].
The "FEMS App Peak Shaving" controls an electrical energy storage system in such a way that the battery is discharged during high grid consumption in order to keep the power at the grid connection point below a defined value ("peak shaving power"). In the example above, this value is 180 kW.
As soon as the grid consumption decreases again and falls below a second threshold value ("recharging power"), the battery recharges itself to be ready for the next peak load. In the example above, this value is 130 kW.

Here you have the option of adjusting the "Peak Shaving Power" and "Recharging Power".
- Measured value
-
The power currently measured at the grid connection point in [W].
- Discharge above
-
The configured "Peak Shaving power" in [W].
- Charging below
-
The configured "Recharging power" in [W].
The value of the "peak shaving power" must not be less than the "recharging power"! |
