&gt; It might be good for time shifting expensive electrical rates but where in America is that going to happen?<p>This happens every day, all across America, it just doesn&#x27;t get made visible to consumers. That&#x27;s why the utility is asking to be allowed to interact with this battery, it&#x27;s just a subtle variation on the smart grid demand management stuff that&#x27;s been going on for the last decade or so, that allows utilities to avoid paying peak rates for electricity generation.<p>(This is also why solar is worth so much in places where the peak load for air-con roughly matches the solar profile)
