There is a solution to managing grid stability, that doesn't need batteries or storage. The utility pays customers to let them remotely monitor and control devices, such as cooktops, water heaters, refrigerators/freezers, and air conditioners. If there is a temporary large peak load, they briefly turn off hundreds to thousands of customer devices for a few seconds to stabilize the grid. Will you even notice? Probably not. But you do get a small bonus credit to your bill, anytime the utility has to do this, and the grid keeps working better for everyone.
