Or better reactive demand. Could my fridge/freezer run at deep chill when energy is cheap? Could an a/c build a block of ice for later? Could tank-based water heater recover more slowly when energy is cheap? Could a parked EV schedule its recharge better? Could a washing machine defer or go into “slow-mode” when cost is high? Same with dishwashers? Could lights dim a bit? Could hvac go into slow mode?

In a way, my utility can do things that force this (voltage reductions), but it’s only really effective for resistive loads, and could increase resistive losses on the transmission/distribution network.

One big problem is that transmission/distribution costs aren’t variable based on time-of-day, but they could be too.
