A few weeks ago I got an email from AGL introducing their "Virtual Power Plant" (VPP) offer, for which the pitch said "can help take pressure off the grid with your solar battery, and earn up to $280 in AGL bill credits." It only currently works with Tesla PW2 and LG Chem RESU.
I downloaded the agreement, at it takes a bit of digging to find out exactly what permissions you are giving to AGL to access your battery!
Unless my logic is faulty, I think they'd have to significantly up the VPP purchase rate to make it compelling.

- $100 sign on credit and 49.32 c/day ($180 per year)
- Under the agreement, AGL can draw power down from your battery up to 30 times ("VPP Events") in 1 year. They say it will be a period of time typically less than an hour but which may be up to 10 hours in duration.
- The agreement does not specify how much power can or will be drawn down during a "VPP Event", but that it will not draw down below 20% of useable energy storage capacity.
- AGL will not tell you when VPP events occur (although you could work it out from the Tesla app when the battery is discharging to the grid!)
