Introduction

Problem Statement Is DR an attractive financial alternative to my current grid

connection?

Traditional Analysis Tools Lack Solution Capability at High Level Too much data required for technical calculation

No limited data set common in packages to perform financial calculation

Package focused on single DR solution or solution approach

Can COTS solution run on my computer platform?

Software Framework

Standard Office Application (Excel) leads to Ease-of-Use

Development Language (VBA) leads to stand-alone migration path Flexibility in time-series data manipulation (15-min to 1 year)

Cookie-cutter solution for other time-series intervals

User interface based on commonly accepted graphic components (push-buttons, dialog boxes, check boxes, etc.)

Ease of deployment across business network
