SAM's battery storage model is for the following types of batteries
- Vanadium redox flow
- All iron flow
It can model the following types of battery storage projects:
- Behind-the-meter projects where the battery is connected on the electricity customer's side of the electric utility meter.
- Front-of-meter projects where the battery is connected on the electric utility's side of the meter or for utility-scale applications.
- Peak shaving where the battery is used to reduce an electricity customer's monthly demand charge.
- Energy arbitrage where the battery stores solar energy during the day and discharges at night.
Although SAM does not have a standalone battery model, a standalone storage system can be modeled using the techniques described in this webinar. NREL plans to add a standalone battery model to SAM in late 2019 or early 2020.
SAM's battery storage model is available with the Detailed Photovoltaic, PVWatts, and Generic System performance models.
