Portland VPP Supporting The Grid During Heatwave

Portland is having *another* heatwave. And our local utility, Portland General, is dispatching our Virtual Power Plant (VPP) to help alleviate the grid strain that the additional air conditioner usage will cause. 

As I pointed out during the last time the VPP was dispatched, in our situation, this dispatch operation can actually increase our grid load. That's because we are load-shifting and reducing our electricity bill

The VPP control software will improve. Next summer, they'll likely be able to account for our use case. In the meantime, our minor increase in load will be more than made up for by others in the VPP. 

Alternatively, I might disable the VPP temporarily to stay "islanded" so that we don't increase our grid load. After all, I volunteered our batteries to help the grid, not increase the burden on it.
