I don't know how familiar any of you are with the savings plans offered through SRP, but my favorite one is the "time of day" plan. From 9pm at night until 1pm the next day, your electricity cost per Kwh is much cheaper than from 1pm -9pm daily. Therefore, in an effort to save money, you would run your electric appliances earlier in the day to avoid the higher costs. For example, I vacuum, run my pool pump, do laundry, use my oven, turn the AC to 76 as early as I wake up until 1pm. At one pm, no more chores for me!! I turn my AC to 80-82 and I try to use my crock pot, or microwave for dinner only so as to not heat up the house from 1-9pm.
My monthly savings from May 1st to September 31st is usually well over $75 on a two story house. It isn't always easy, but it is worth it to me.
