Model an auxiliary load as a percentage of the storage energy capacity (MWh). If the storage serves the auxiliary load, the minimum state of charge is increased by the given percentage. Otherwise, the load is assumed to be served by an external source such as the grid. You can provide either a flat rate or a time series price strip.
Variable |
Description |
Auxiliary Load (%) |
Set % to model an auxiliary load as a percentage of the energy storage capacity (MWh) |
Storage Self-Services Auxiliary Load |
To model a system where storage serves its own auxiliary load, use the toggle to enable self-serving. This will increase the storage’s minimum state of charge by the same amount as the auxiliary load percentage. |
Select Energy Market |
If “Storage Self-Serves Auxiliary Load” is not enabled, the auxiliary load will be served by purchasing energy from the grid. To purchase the energy from an Energy Market, select this option and use the drop-down menu to elect which Energy Market the system will purchase the auxiliary load energy from. |
Flat Rate ($/MWh) |
If “Storage Self-Serves Auxiliary Load” is not enabled, the auxiliary load will be served by purchasing energy from the grid. To purchase energy at a flat rate, select this option and enter the purchase price in $/MWh. |
Flat Price Escalator (%/yr) |
define an escalator to the flat rate price specified above in $/MWh. The escalator can be set as a constant value in %/year or as varying values by utilizing the Escalation by Year table |
