This report summarizes results from a two-year Consumer Behavior Study (CBS) executed by Green Mountain Power (GMP) as a component of the eEnergy Vermont Smart Grid project. The purpose of this study was to understand and compare two different types of electricity pricing structures: Critical Peak Pricing (CPP) and Critical Peak Rebate (CPR; also known as the Peak Time Rebate), both of which are intended to provide incentives for residential electricity customers to reduce demand during peak hours. In addition the study sought to identify the additional value of In-Home Display technology in reducing peak hour and monthly electricity consumption.
