An increase in embedded generation is the same as a decrease in load to the system. So turning a heater off is akin to “pushing power in to the system”, unless the embedded generation is larger than the load on a feeder, in which case the direction of power flow would be reversed, which may or may not cause problems depending on the protection settings at the substation.
The peak system load and generation on the Western North American grid is 167,000 MW. There is so much inertia there a 10kW power wall isn’t going to do anything.
