Since 2009, the U.S. Department of Energy, using funds from the American Recovery and Reinvestment Act, and the electric power industry have jointly invested over $7.9 billion in 99 cost-shared Smart Grid Investment Grant (SGIG) projects. 

As part of the SGIG program, 10 electric utilities agreed to conduct 11 consumer behavior studies and produce comprehensive reports with the aim of evaluating customer responses to various types of time-based rate programs implemented in conjunction with information and control technologies such as in-home displays and programmable communicating thermostats. Four of the studies are complete; seven others are in various stages of implementation.

A new report presents the results from the interim and final evaluations for the four utilities with projects completed by December 31, 2014, as well as results from the interim reports of six other utilities.

The full report is now available for downloading.
