We already provide several export products where customers can benefit from exporting energy to the grid at key times, such as Outgoing Agile and the Tesla Energy Plan. We've done several trials (including Powerloop and Powervault GridFLEX) to understand the implications of customers exporting energy to the grid.
For this trial, we want to understand how customers with import only can help shift demand to give an insight to how this could be used across the whole population. We will, however, definitely look to include export customers in future trials!
