7 Cost-Benefit Analysis Guiding Documents Methodological Approach, published Jan, 2010 Jointly funded by DOE and EPRI Provides framework for estimating benefits & costs Provides definitions, concepts and data sources Publicly available: Product ID Guidebook for Cost/Benefit Analysis of Smart Grid Demonstration ti Projects: Measuring Impacts and Monetizing Benefits, provides a manual for practical application with step by step instruction provides guidance for documenting the project in detail and approach to perform a CBA, includes templates for working through the process. Vol. 1 Publicly available (Replaced): Product ID Rev. 1 publicly available(jan. 2013): Product ID

Impacts are measurable physical changes within the bounds of the demonstration system. Impacts are differences between a measured quantity and its baseline measurement. Benefits are monetary products of impacts. Some may be costs. In short: We measure impacts, calculate metrics, monetize costs and benefits. 8
