PV+Battery+Load, where the battery is allowed to export energy to grid was created by BarbaraLemes
Hi there, 

Thank you for the tool and really appreciate it if you can help me with the request. 

I'm having trouble simulating a PV system + Battery + Load where the battery is allowed to export energy to grid. I know that in BATTERY STORAGE>> PPA it's possible to send energy from a battery to grid, but I need to do it with a specific PV system and load. How can I do this ( PV+Battery+Load, where the battery is allowed to export energy to grid) in SAM?

Could you please help and advice as to what I should be doing. Appreciate your help.

Hi Barbara,

You should be able to model this type of system by using one of the financial models for behind-the-meter (BTM) battery storage: Commercial, Residential, or Third Party Ownership Host / Developer. Those models have inputs for the building or facility load, and dispatch storage to reduce the building owner's monthly electricity bill.

Best regards,
Paul.

Thank you for your answer. But I think I haven't made myself clear.

When I use  "PV-battery,Residential"  I'm not able to send energy from battery to grid. It's possible only to send energy from PV system to grid, but i can't do the same with the battery ( this is interesting for me because I have TOU rates).

As you can see in the screenshot I don't have the option in "TIME SERIES" to see the wave "electricity to grid from battery" when I choose "PV-battery,Residential", it's only possible when I choose "Battery>PPA>Single Owner" where I can't input a load.

I will really appreciate it if I could simulate a system with PV+Battery+Load where the battery is allowed to export energy to grid and I could see it. Is it possible? How? Thank you very much.

PV-Battery,Residencial
