Hi, I have APS, that being said I called them to help me figure out how much my kilowatt per hour is. What a joke. They purposely make it impossible. I am on the Combined Average Plan. I have a B128, a 1hp 1.4 service factor pump. It needs to be replaced and I am going to get a 2 speed pump. Right now I run it off peak at night for around 5 hours. In the summer it runs about 6 hours at night and maybe 2 during the day... Can anyone give me a clue how much I will save and also the figures that you use to determine this?
