Hi Sofiane,
Thank you for sending the file.
This file was last saved using an older version of SAM. I was able to fix the file by opening it in SAM 2020.11.29 Revision 2. If you are using SAM 2020.11.29 Revision 1 or SAM 2020.11.29, I would recommend updating to Revision 2. You can update your version of SAM by clicking
Check for updates when you first start SAM (the button is at the bottom left corner of SAM's Welcome page), or by downloading it from the list of Legacy versions on the SAM website Download page:
sam.nrel.gov/download.html.
If you want to use this file in SAM 2021.12.02, you will need to first open it in SAM 2020.11.29 Revision 2, save it, and then open it in SAM 2021.12.02. In SAM 2021.12.02, you will also need to change the option on the Electricity Purchases page from
Use PPA or market prices to
Use retail electricity rate(s).
Best regards,
Paul.
