9. Savings from energy-efficiency programs typically are measures at three levels: ex ante , or as designed; “gross” savings, or ex ante estimates adjusted for the actual conditions; and “net” savings—gross savings adjusted for market effects such as free-ridership, spillover, and take-back.
10. As a simple example, if a utility has a 90-percent probability of achieving its annual savings target in each year, and savings in each year are determined independently, there would be only a 73-percent probability of the utility reaching its target in every year and earning the maximum award.
