Battery Discharge Efficiency
| Units: | % |
| Mode: | Input Only |
| Multi-band: | False |
| Default Value: | 100 |
| Validation Rule: | Between 0 And 100 |
| Key Property: | No |
| Description: | Efficiency of discharging |
Battery Discharge Efficiency is the ratio of power sent to the grid over total power discharged from the battery i.e. including any inverter losses.
Example:
| Battery | Property | Value | Units |
|---|---|---|---|
| BESS | Units | 1 | - |
| BESS | Max Power | 10 | MW |
| BESS | Discharge Efficiency | 90 | % |
If the BESS operates at Max Power
of 1 MW for one hour then 1 MWh is
delivered to the grid as Generation
and 1 / 0.9 = 1.11 MWh Discharging
is taken from storage reducing the SoC.
The losses are 0.11 MWh.
