If it saves me $20 bucks a month, why not?
Sounds great. There are so many benefits, including automatic sensing of low electric rates during the day. If I could actually see when I'm saving money, that would help me decide when to do high energy use things like baking or using big power tools. The utility company would have quite a bit more efficiency, too, allowing it to produce less excess power. But I think utilities should focus a lot on more efficient and upgraded transmission lines asap.
