Back in January when Google announced it would spend $3.2 billion to purchase Nest, EDF knew this was a company to watch. The results of three new reports, released today, confirm that controllable thermostats like the Nest Learning Thermostat are both customer-friendly and useful for energy system planners. Moreover, the reports signal that smart devices, such as those Nest manufactures, have potential for generating marked savings for utility customers.
The reports analyze 2012-2013 energy use data gathered from four major utilities across the U.S. that offer Nest energy services programs: Austin Energy, Reliant Energy, Green Mountain Energy, and Southern California Edison.
The first report evaluates the results of Rush Hour Rewards, a demand response service that changes the temperature of the homes of Nest users during energy “rush hours”, or times when demand on the grid is highest. The second examines Seasonal Savings, a program that runs for three weeks and slowly modifies the temperature according to the customer’s behavior (which this smart thermostat is able to ‘learn’ via its built-in motion sensor and understanding of its owner’s temperature preferences). Both operate during times of heavy usage, namely winter and summer. The third report analyzes home energy data of Nest customers more broadly, comparing energy use before and after the installation of a Nest Thermostat. Read More
