Emission Generators Production Rate
| Units: | kg/MWh (Metric), lb/MWh (U.S. Imperial) |
| Mode: | Input Only |
| Multi-band: | True |
| Default Value: | 0 |
| Validation Rule: | Any Value |
| Key Property: | No |
| Description: | Emissions produced per MWh of generation |
Emission Generators Production Rate defines the rate of emission production as a function of the megawatt Generation. This on top of emissions defined via the Generator Fuels membership and Fuel Production Rate.
Production Rate is useful for emissions such as "NOx" that are best expressed as a function of both Fuel Offtake and Generation.
Example
| Generator | Property | Value | Units |
|---|---|---|---|
| CCGT1 | Units | 1 | - |
| CCGT1 | Max Capacity | 320 | MW |
| CCGT1 | Heat Rate | 7.9 | GJ/MWh |
| Emission.Generators | Property | Value | Units |
|---|---|---|---|
| "NOx" Generators "CCGT1" | Production Rate | 1.25 | kg/MWh |
Setting Emission Production Using Load Points and Bands
PLEXOS allows you to set emission production values using the Load Point and Production Rate properties. It is important to note that PLEXOS does not create an interpolated string of data but treats the settings like blocks.The limit is "backward facing" for the following setting PLEXOS will allocate emission rates as follows:
- Load Point Value = 10 MW - Band is set to "1"
- Load Point Value = 190 MW - Band is set to "2"
- Load Point Value = 800 MW - Band is set to "3"
- Production Rate Value = 5kg/MWh - Band is set to "1"
- Production Rate Value = 10kg/MWh - Band is set to "2"
- Production Rate Value = 20kg/MWh - Band is set to "3"
PLEXOS will allocate the emissions as follows:
Note: The last block includes the value of Max Capacity of the generator. If this block is not included, no emission will be allocated for that block.
