I was one of the first Griddy engineers (though I’m no longer there). We would have people call & complain when the cost for a day was much less & they had AC blasting. I wonder how the customer support reps are dealing with all of this.
Griddy's communication efforts have generally grown increasingly proactive since we joined in June 2017, and they have been very proactive over the past ~10 days. They sent informational emails on the 6th, 9th, 12th, 13th, and 14th notifying us about upcoming high-price/demand periods, what hours things are expected to spike, and providing suggestions for avoiding/mitigating energy use.
It's faster to do that than to go on the phone and complain or ask for a "discount" (where you would still be paying more).
(I don't know about other states, but this is extremely easy to do in Texas.)
