With this meter, you pay mucho less denero during the off peak hours, which is where I get the $0.019/KWH. This is when I run my lights, washer, dryer, dishes, cool my house in the summer, etc. BUT during the on peak hours you pay more than the normal KWH that everyone pays normally. You run most of your appliances at night and not during the day you save so much more. Last bill was for $84 for 1586 KWHs. You have to call your electric company and ask for it by name. They won't offer/suggest it out of the blue.
