I was a little surprised by it too. The new "smart" power meters that are starting to be installed by power companies deliver hourly power use data to the power company for a variety of reasons. Parts of California US has a moratorium on these smart meters for "health and privacy" reasons https://en.wikipedia.org/wiki/Smart_meter#California https://en.wikipedia.org/wiki/Smart_meter#California I though you could write a good mystery that could be solved using a power monitoring system... But alas I am not a writer.
