West Penn Power AMENDED Program Year 3 Final Annual Report

quarter one and quarter two program participants, this was updated to 45 percent electric and 55
percent gas. These energy savings were compared to the DSM tracking system's claims and used to
develop a realization rate that was applied to the population of clothes washers and dishwashers
rebated through the program.
The DSM tracking system assumed that programmable thermostats were all used on electric furnaces.
ADM assumed that the statewide baseline study results for the type of heat statewide was applicable to
WPP. Based on this review, the desk review realization rate for programmable thermostats was
determined to 0.33 for kWh. .
The other measures within this program resulted in realization rates for kWh and kW at or near 1.00
with minor data discrepancies or calculation corrections identified.
The M&V of the upstream CFL program component does not require field work or customer surveys. A
census of shipment invoices along with the calculations in the DSM tracking system were reviewed to
ensure that the energy savings and demand reductions are claimed according to the protocols in the PA
TRM. The review determined a realization rate for the CFLs component of 0.999 for kWh and 0.985 for
kW.
The sampling approach for the appliance rebate program component is batch- stratified random
sampling on a quarterly basis (for on-site verification). A sample point in the context of the appliance
rebate component of this program is defined as "one appliance." A census of the energy and demand
savings calculations in the program tracking data are reviewed to ensure that the energy savings and
demand reductions are claimed according to the protocols in the PA TRM, as described in the previous
section.
The impact evaluation for the appliance program component included verification of installation
through web surveys and a 0.983 savings realization rate across appliances offered was determined;
that is, 98.3 percent of those surveyed that they purchased and installed qualified appliances, and
participated in West Penn Power's Energy Efficient Products Program. Note that dehumidifiers were not
included in the program participation files for PY3 quarter one and quarter two and therefore were not
verified in the survey effort. This measure will be fully verified in PY4.
The combined overall program realization rates at the program level are 0.960 for kWh and 0.930 for
kW.
