Wikipedia has a smart meter entry that has this to say about privacy:

Smart meter power data usage patterns can reveal much more than how much power is being used. Research has been done which has demonstrated that smart meters sampling power levels at two-second intervals can reliably identify when different electrical devices are in use and even what channel or program is being viewed on a television based on the electrical consumption patterns of these devices and the electrical noises that they emit.

"...smart meters are able to become surveillance devices that monitor the behavior of the customers leading to unprecedented invasions of consumer privacy. "
