Localized storage on households and businesses can help even if it never feeds back to the grid, because it means that batteries can charge via off-peak electricity and switch to discharging to fulfill local demand during grid peak times. It has pretty much the same system effect as discharging into the grid during peak demand but it's more efficient to use the electricity at the same point it was stored.
