Anyone signed up on this? It seems to be a tiered pricing plan with a pretty steep discount on off peak hours. I recently signed up thinking I would save a few bucks. I've gotten two texts today. 1st one says that tomorrow's peak period (2 to 7 p.m.) rate is going to the high rate of 23 cents per kwh. About 2 hours later I get another saying they are calling a critical event for 3 p.m. to 6 p.m. and charging 46 cents. Yesterday was the 1st day since I signed up that they even went on the high rate, it's just been the "normal rate" during peak hours until yesterday. At least as long as I've been on it anyway. According to their site I am saving a bit, but I'm wondering now...
