““The Lowly Thermostat, Now Minter of Megawatts How Nest is turning its consumer hit into a service for utilities. Peter Fairley | 945 words • Google’s $3.2 billion acquisition of Nest Labs in January put the Internet of things on the map. Everyone had vaguely understood that connecting everyday objects to the Internet could be a big deal. Here was an eye-popping price tag to prove it. Nest, founded by former Apple engineers in 2010, had managed to turn the humble thermostat into a slick, Internet-connected gadget. By this year, Nest was selling 100,000 of them a month, according to an estimate by Morgan Stanley. At $249 a pop, that’s a nice business. But more interesting is what Nest has been up to since last May in Texas, where an Austin utility is paying Nest to remotely turn down people’s air conditioners in order to conserve power on hot summer days—just when electricity is most expensive. For utilities, this kind of “demand response” has long been seen as a killer app for a smart electrical grid, because if electricity use can be lowered just enough at peak times, utilities can avoid firing up costly (and dirty) backup plants. Demand response is a neat trick. The Nest thermostat manages it by combining two things that are typically separate—price information and control over demand. It’s consumers who control the air conditioners, electric heaters, and furnaces that dominate a home’s energy diet. But the actual cost of energy can vary widely, in ways that consumers only dimly appreciate and can’t influence. While utilities frequently carry out demand””
