West Penn Power AMENDED Program Year 3 Final Annual Report

ADM evaluated the commercial and industrial programs using stratified ratio estimation. Separate
samples were drawn, at the 85% confidence level with 15% precision at the annual evaluation level, for
each operating company, program, and quarter. A 'sample point' denotes a particular rebate which was
randomly sampled within its population.
At the end of the second, third, and fourth quarter ADM reviewed tracking data to define a discrete list
of rebates that became the'sample population for that quarter. Once separated Into their respective
operating companies and programs, this population was then stratified according to measure category
(prescriptive vs. custom), common drivers of realization rates or the variability of the realization rates,
modes (e.g. "Standard Lighting Rebate" rebates vs. other prescriptive rebates), and the magnitude of
rebated savings (used to create 'certainty' strata). ADM used a coefficient of variation (CV) of 0.5 for all
qualitative strata that 26 , based on the PY2 evaluation, are expected to have homogenous realization
rates for sampled projects and a CV of 1.0 for strata that, based on the PY2 evaluation, are expected to
have homogenous realization rates for sampled project. In late PY3, many conservation kits that
included CFLs were mailed out to small commercial customers. The CFL mailings were placed into three
separate strata in ADM's sampling framework. ADM conducted a metering study to establish hours of
use for CFLs installed in facilities that fall into the 'other' category.

Streetlights are given a CV of 0.4 but the PY2 evaluation proved that the variance is in fact much smaller than
that.
