Electricity savings one, two, and three years after participation in the BPA Residential Weatherization Pilot Program
Abstract The Bonneville Power Administration (BPA) operated a Residential Weatherization Pilot Program from 1980 through 1982. The program provided free home energy audits to 7200 electrically heated homes in the Pacific Northwest and gave zero-interest loans to weatherize 4100 of these homes. The total cost of the program was almost $11 million. This paper estimates the energy-saving effects of the BPA program. The data used include one year of preprogram and three years of postprogram electricity consumption records. The first stage of our method involves estimation of weather-adjusted annual electricity consumption for each household. The second stage uses this weather-adjusted consumption as the dependent variable in a pooled time-series/cross-section regression model of electricity use. The total annual electricity savings experienced by the households that received both an energy audit and a weatherization loan averaged 19 GJelec/year one year after participation, increasing to 22 GJelec and 23 GJelec two and three years after participation. The net annual electricity savings that can be directly attributed to the BPA pilot program for these households averaged 16 GJelec (15% of preprogram use) one year after participation and declined to 15 GJelec two years and three years after participation. Program-related savings decrease over time, presumably because participants would have been stimulated by other factors (especially rapidly rising electricity price) to adopt conservation actions.
