Payback Acceptance Data Sources:

1. Commercial. ICF survey of 231 non-residential customers on decision making criteria for selecting efficient efficient units. Conducted in 2013 for a confidential utility. 2. Residential HVAC. ICF survey of 300 residential customers on decision making criteria for selecting efficient HVAC units. Conducted in 2013 for a confidential utility. 3. Industrial. U.S. Department of Energy, Industrial Assessment Center (IAC) data on industrial efficient measure implementation in Louisiana. Data accessed in 2014. 4. Residential Lighting. ICF survey of 300 residential customers on decision making criteria for selecting efficient lighting. Conducted in 2013 for a confidential utility. 5. Residential Appliance. ICF survey of 300 residential customers on decision making criteria for selecting efficient appliances. Conducted in 2013 for a confidential utility. 6. Residential - Other Measure Types. Based upon national survey of residential customers by the Shelton Group (2006).

Notes:

 The above payback acceptance curves plot months or years of simple payback against customer stated payback acceptance rates, with the exception of the industrial curve where actual payback from implemented efficiency measures was utilized to develop the curve. As stated in the body of this report, payback acceptance curves were not used in forecasting participation for all measures - they were used only for measures where payback is a valid proxy for financial acceptance.  The table below shows which Participation Approach (see Approach section of main report for descriptions of Approach A and Approach B) was used by measure group by program, and the payback curve used, where applicable.
