2.3 Impact Evaluation Net Savings
Act 129 compliance Is based on gross savings, but the Company's Evaluators are presently finalizing a
portfolio-level net to gross survey to inform the program planning for Phase II of Act 129. The
evaluation of the legacy FirstEnergy companies included net-to-gross research based on Program Year 3
(PY3) participants. Given the mid-year transition of West Penn Power programs to FirstEnergy's model.
West Penn Power specific net-to-gross research was not conducted. The evaluation team plans to
complete net-to-gross research on West Penn Power program participants starting in February 2013 and
based on six months of PY4 participants. These results will be available in time to inform the final plans
for Phase II. The Net-to-Gross data acquisition will be based on participant self-report surveys and will
follow a similar approach as that used for the FirstEnergy legacy companies.
Program Sampling:
The .sampling approach for this program is a simple random sample. Sample sizes will target 90%
confidence level and 10% precision.
2.4 Process Evaluation
The objectives of the process evaluation study were to assess the following:
» Understand how customers heard about the recycling rebates
« Assess customer experiences participating in the Program
• Assess customer decision making processes and indicators of free-ridership
• Collect information about the customer's old appliance
• Collect housing characteristics and household demographics
Methodology
Tetra Tech conducted a Residential Participant Survey with a representative sample of customers who
recycled qualified appliances and received a rebate in PY3 quarters one and two. The survey population
was comprised of 1,434 "recycle only" customers, or customers that only received a rebate for recycling
their appliance and did not receive a rebate for purchasing a qualified new appliance. A random sample
of 203 records was selected from the population. Customers were sent a mail invitation to complete
the on-line survey with email and telephone follow-up to maximize response.
