In California, the law explicitly protects the privacy of power customers, prohibiting public utilities from disclosing precise “smart” meter data in most cases. Despite this, Sacramento’s power company and law enforcement agencies have been running an illegal mass surveillance scheme for years, using our power meters as home-mounted spies. For a decade, the Sacramento Municipal Utilities District (SMUD) has been searching through all of its customers’ energy data, and passed on more than 33,000 tips about supposedly “high” usage households to police. Ostensibly looking for homes that were growing illegal amounts of cannabis, SMUD analysts have admitted that such “high” power usage could come from houses using air conditioning or heat pumps or just being large. And the threshold of so-called “suspicion” has steadily dropped, from 7,000 kWh per month in 2014 to just 2,800 kWh a month in 2023. This scheme has targeted Asian customers. SMUD analysts deemed one home suspicious because it was “4k [kWh], Asian,” and another suspicious because “multiple Asians have reported there.” Sacramento police sent accusatory letters in English and Chinese, but no other language, to residents who used above-average amounts of electricity. Last week, we filed our main brief explaining how this surveillance program violates the law and why it must be stopped. This type of dragnet surveillance ... is inherently unreasonable.
