Hi again,
We will fix the bug with the price signal forecast dispatch option for the next update to SAM 2021.12.02:
github.com/NREL/ssc/issues/561
And, to clarify my response above, the peak shaving dispatch option does consider monthly peaks. The algorithm is described in DiOrio, N. (2017). An Overview of the Automated Dispatch Controller Algorithms in SAM. NREL/TP-6A20-68614. (

). Specifically, see the last paragraph of Section 3.2 on p. 7. You can find other battery-related publications on the SAM website at
sam.nrel.gov/battery-storage/battery-publications.html.
The peak shaving algorithm is not aware of the electricity bill calculation, so it is not possible for it to respond to ratcheting demand rates. The battery responds to the available power from a PV or other system if there is one, and to the load.
Best regards,
Paul.
