To: Don Jones, PacifiCorp/Rocky Mountain Power From: David Basak, Navigant Date: 06/04/2012 Re: Idaho Home Energy Savings Program Cost-Effectiveness Results

This memo presents the cost effectiveness findings for the analysis of the Idaho Home Energy Savings (HES)
Program. The memo addresses the following:

• Avoided Costs: The team performed an analysis using the Residential Whole House decrement cost
scenario for “Medium” carbon streams provided in the 2011 PacifiCorp Integrated Resource Plan.
• Modeling Inputs: Navigant utilized individual measure savings and administration costs provided by
PECI in the file ID HES State Savings Summary_06042012.xlsx.
• New/Revised measures: Navigant ran benefit-cost tests for both the old and new/revised measures
strictly for the program summary. The individual measure level results presented below only include
the new/revised measures.
• Benefit/Cost Tests: Multiple benefit/cost tests are reported including; PacifiCorp Total Resource Cost
Test (PTRC), Total Resource Cost Test (TRC), Utility Cost Test (UCT), Rate Impact Test (RIM), and
Participant Cost Test (PCT).

This memo will begin by addressing the program level results which include the complete list of measures (old
and new/revised) included in the Idaho HES program. The cost-effectiveness results are as follows:

Table 1 –Cost Effectiveness Analysis Inputs
Parameters Values
Discount Rate for all B/C Tests 7.17%
Line Loss Factor - Energy (%) 9.96%
Residential Energy Rate ($/kWh) $0.094
Inflation Rate 1.8%
