The evaluation of the legacy FirstEnergy companies included net-to-gross research based on Program Year 3 22 Strata boundaries for this sampling design are not applicable as a random sample was pulled for each measure's population that included all participants.

(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. 7.4 Process Evaluation Tetra Tech conducted a telephone survey of customer who participated in the program in PY3 quarter 1 and quarter 2. The objective was to: • Learn about the installation and use of measures • Learn about experiences and satisfaction with participation in the program • Understand their level of interaction with the auditors," what was learned, and actions taken as a result of the experience Methodology Tetra Tech randomly sampled 525 Home Performance Check-up participants with the airrfof reaching 105 compJeted participant surveys out of a population of 5,020. Kev Findings The audits are providing participants with new energy saving information and, as a result, customers are acting on some of those recommendations. With the exception of those that reside in multifamily buildings, most respondents recalled an auditor coming to their home and discussing ways to save energy, Auditors, on average, spent a little over an hour with customers. This time includes the 30 minutes of energy education to be provided to the customer as well as the walk-through audit. In addition, the program appears to be providing participants with some specific suggestions on how to save energy in their homes. A varying percentage of customers report acting on some of the recommendations based on the audit experience, including turning lights off when not in the room and unplugging electronics when not in use.
