But, at the same time, consumers that have no visibility into their current electricity prices are unable to alter their behaviour. Until there's extremely high-resolution, real-time price transparency, this system is destined to fail.
Also consumers have base loads just like generators have base loads: you might defer doing laundry, but no one is going to unplug their refrigerator during a electricity price surge. Again, this simplistic spot pricing scheme is destined to fail if it doesn't meet consumer's need to have predictable baseline consumption rates.
I weakly agree with the author here that demand-based pricing is in everyone's interest, but that said, last week in Taxas was a systemic failure of immense proportions and everyone involved in planning Texas' electricity grid should be ashamed.
