BTM Bess System

Hello, everyoneI need to model a PV + battery system for a behind-the-meter project. This involves purchasing energy at a given price per hour, in addition to other energy charges. It also needs to have the option to include or exclude a solar system. Additionally, there are demand charges that apply only from April to September, from 7 PM to 10 PM

Hi Alvaro,

You should be able to model these scenarios in SAM.

Some of the videos on the Battery Videos page may be helpful: sam.nrel.gov/battery-storage/battery-videos.html

From your description, it sounds like a PV Battery / Commercial configuration would work well. I would suggest creating a default case, running a simulation, and exploring the results to familiarize yourself with the model and get a better idea of what to focus on. The Electricity Rates input page is where you'll provide inputs describing the electricity purchase price and demand charges. You will also need to provide load data on the Electric Load page.

Refer to the Help system for the different input pages if you need help understanding what the inputs are. Let us know if you have any specific questions.

Best regards,
Paul.
