Section 7
Evaluation and Selection of Conservation
Measures and Programs

In this section the estimated savings and costs of the conservation measure/programs
selected in Section 6.3 are presented. The net benefits and costs are compared and a
final group of conservation measures and programs are selected for implementation.

7.1 Combinations of Measures and Programs

Conservation measures/programs are often used in conjunction with one another. In
order to facilitate a more integrated assessment of the benefits and costs, the
conservation measures/programs selected for evaluation were grouped into
combinations. The combinations were developed by identifying the type of
program/measure and the end user each program/measure targets. Table 7-1 lists the
combinations as well as the conservation measures/programs within each
combination.

acquired for the year presented in the table. Cumulative savings are applicable for the
majority of conservation measures/programs and are noted in the calculations
