I'm a Texas residential customer. I've tried Griddy, the only service that exposes the customer directly to the wholesale electricity rates. Over two days, my electric bill mounted to somewhere around $1600. I'm not complaining, because in ~18 months prior to that, those low (and sometimes negative) $/kWh actually saved me around $2,000. Not for everyone. But one effect of these real-time communicated rates, is my house skipped running equipment that would have consumed 50kWh+ during those $9.00/kWh periods. Accordingly, by adjusting my demand, in response to limited supplies, I made it possible for other Texans to not get crushed by a rolling blackout. In addition, if thousands of people adjust their demand in this manner -- it can make it possible to reduce the CO2 emissions associated with the mere construction of a peaker plant, that, itself, might get used only 10-15% of the time.
