Experts: Smart grid poses privacy risks

Technologists already are worried about the security implications of linking nearly all elements of the U.S. power grid to the public Internet. Now, privacy experts are warning that the so-called “smart grid” efforts could usher in a new class of concerns, as utilities begin collecting more granular data about consumers’ daily power consumption.

“The modernization of the grid will increase the level of personal information detail available as well as the instances of collection, use and disclosure of personal information,” warns a report (PDF) jointly released Tuesday by the Ontario Information and Privacy Commissioner and the Future of Privacy Forum, a think tank made up of chief privacy officers, advocates and academics.

Smart grid technology — including new “smart meters” being attached to businesses and homes — is designed in part to provide consumers with real-time feedback on power consumption patterns and levels. But as these systems begin to come online, it remains unclear how utilities and partner companies will mine, share and use that new wealth of information, experts warn.

“Instead of measuring energy use at the end of each billing period, smart meters will provide this information at much shorter intervals,” the report notes. “Even if electricity use is not recorded minute by minute, or at the appliance level, information may be gleaned from ongoing monitoring of electricity consumption such as the approximate number of occupants, when they are present, as well as when they are awake or asleep. For many, this will resonate as a ’sanctity of the home’ issue, where such intimate details of daily life should not be accessible.”
