This is just my opinion. SDG&E wants you to crank up your AC units to pre-cool your house early in the day. Then just use fans between 4 and 9 PM. This will make more profit for them if people use the Time of use plans (TOU.) By people using more power in the early part of the day it will make up for the lower usage in the evening. So really they aren't out anything. It just makes people feel good that they are saving energy while all the time SDG&E isn't out of anything. They are however saving their money by not building more peak generation stations. They are squeezing every dime out of the existing equipment without building anything new. We run the AC durning the day and late afternoon. Then when the outside temperature drops we start up the whole house fan. Same thing for the early morning hours to bring in the cooler air. We have the ac set at 78 so it doesn't kick in until about 1 or 2 pm. I'm all for conservation but not at the expense of SDG&E customers to conserve while they just sit on their money and not build anything to help with the situation. As more homes are being built the power consumption will go up. Their answer to the situation will probably be like in the past, rolling brown outs. That will cost them less in profits then building new peak generation stations. Just my opinion, your mileage may vary.
