It's not only privacy that concerns me but the intrusive acts that a utility or government can perform without the need to acquire permission from the authorities.
For example, there have already been instances where a customers power has been turned off by the utility company because they, in their opinion, felt the customer was using too much power.
Also there are instances where the utility has accessed the customers appliance, in this case an air conditioner, and either turned it off or down due to using too much power.
Other things to be aware of include the fact that all the major appliance manufacturers are building the "ZIGBEE" chip into their appliances. This chip is a wireless device that communicates with your smart meter and provides power consumption information on demand. In fact the governments of some provinces and states will demand that you retro fit your appliances with a device containing the "ZIGBEE" chip to allow harvesting of your data.
Also be well aware that these smart meters produce burst mode "EMR" (electronic microwave radiation). They send the data every few seconds 24/7. There are numerous documents military, government and business that have been kept from the public domain because they describe the danger of microwave radiation and how it affects the human body.
Be also aware that people are getting sick from this radiation. The radiation not only from the meters but from cell towers and cell phones. Many doctors have declared this sickness as a real illness resulting from the microwave radiation created by these devices.
If you want accurate documentation just go to one of these web sites. There is much more available if you google "smart meters" or "zignee".:
