Minnesota Power is pleased to provide the Department of Energy with this interim report of the outcomes so far from the consumer behavior study associated with the Department of Energy under Award Number DE-FOA-0000058. The Consumer Behavior Study Plan (CBSP) is a part of the broader Smart Grid Investment Grant being executed by Minnesota Power. The overall purpose of the CBSP is to evaluate customer acceptance and response to various forms and timing of usage information feedback, some of which are enabled through advanced two-way meters. Through its Power of One? conservation program, Minnesota Power helps customers develop, implement, and adapt a plan to save energy through information, tools and technology options. The Power of One program is an effective, multi-faceted effort, with the residential portion yielding about 20 percent of Minnesota Powers annual conservation savings result. The CBSP is a timely and incremental extension of that effort which incorporates additional technologies such as advanced metering infrastructure (AMI) to help residential customers learn more about how they use energy. The CBSP seeks to test customer response to enhanced usage feedback that is higher in frequency and specificity as compared to the monthly usage information customers currently receive.
