That would cost money and lower the profits of the people that own/control the grid. I sometimes wonder how much money these robber barons spend on lobbying and other PR campaigns to convince that climate change isn't a problem and that the grid is just fine. It's one of those unanswerable questions I'm sure, but how much progress could be made by redirecting that amount of money to actually improving the grid itself?
That was actually part of how I intended my "negotiated" to be taken. Part of it is a monetary negotiation where we invest more in base load and peak load, but some of it needs to be in the ability for the grid to request to shed load and the devices react accordingly.
