You got lucky!!Can you link me to where this language is? to define the 15 kW "peak annual demand" for 3x Powerwalls?
My large-scale SGIP was submitted this way, and PG&E didn't seem to say anything. I can't find language that says the minimum actually experienced is 15,000 kW in an hour.
My greenbutton data peaked at 11.5 kW used in an hour through chance; I didn't realize I had to try and hit 15 kW.
