I don’t think that was my hope. My comment, if anything, is that the dynamics of pg&e’s retail pricing make the comparison a bit of (pardon the pun) apples to carrots. Plus, there’s no analogy for energy, at scale, to refrigerated supply chains; hence need for TOU pricing to shape demand.
I suppose you hope it's relevant because, "the solar power comes just when they need it the most" ?
They don't seem to do the math quite so happily, though. Maybe it's #1 and #2:
First, Safeway buys in very large lots from certified suppliers, who can commit to (almost) always having carrots.
Second, those suppliers have to deliver at a loading dock, and maybe at a central location, too.
