Our calculations indicate that a $100 investment in a weatherization project with a 25 year life would result in a present value bill reduction of $230 and a present value system benefit (avoided cost) of $320. The above comparison is drawn for an analysis that we asked Pete Pengilly from our Energy Efficiency Research and Analysis group to perform. His analysis is attached. The analysis shows that a $200 annual bill credit (escalated) over 25 years has a present value of $3,216 in bill reduction benefits to the customer (Direct Bill Reduction tab). In comparison, if the Company spends a present value amount of $2,949 to weatherize a home, the present value bill reduction benefit to the customer is $7,021 and the Idaho Power system benefit is $9,733. (WAQC Investment tab). The inputs for the weatherization analysis are from the 2008 WAQC annual report. Although it gets to be a lot of numbers, the bottom line is efficiency is the best bang for the dollar.
