Aside from all the BS, there are some good points, like giving the power company the ability to more finely analyze usage patterns of individuals. However, they'd have to have a receiver very close by. One watt is not much power. The real value is more likely simplifying meter reading. At one watt, a meter reader could drive down a street and a receiving computer in the car can collect data as he drives by. No more cases where the reader can't get in because of a vicious dog. Less time. Fewer people. These have traditionally been high turnover positions. Overall a better way to do the job, and it can be done more often, rather than the periodic readings power companies like mine perform. They bill for what you have historically used. Then take a reading and adjust billing to correct for the error. With this system, they could do the reading every month and give me an accurate bill.
To the power company, in terms of usage, what's really important is what the total load on the system is so that the power company can accommodate that load. They know what they need not by individual usage but by aggregate usage of all the customers in a service area.
