9-C-iiAPPENDIX 9-C. NATIONAL ENERGY SAVINGS AND NET PRESENT VALUE

USING ALTERNATIVE ENERGY PRICE SCENARIOS

9-C.1 INTRODUCTION

This appendix presents national energy savings (NES) and net present value (NPV) results for alternative economic scenarios (for water heaters, direct heating equipment and pool heaters), and alternative energy price scenarios for all product classes. DOE explained the calculations of NES and NPV using the reference installation costs and the default energy price forecast in chapter 10, National Impact Analysis.

9-C.2 RESULTS USING ALTERNATIVE ENERGY PRICE SCENARIOS

For each product class, DOE calculated NES and NPV using energy price scenarios from the High and Low Economic Growth cases. The NES results are the same in each energy price scenario. As one would expect, the NPV is most favorable using prices in the High Growth scenario, and least favorable using prices in the Low Growth

scenario.
