Market Characterization Findings:
• Active utilities participated in ESUE program or have regulatory/legislative (e.g. I-937) directives; • Awareness/understanding of DE efforts is fairly high (all IOUs and Active Publics) but not always the case at smaller, more rural utilities; • Respondents overwhelmingly believe that there are opportunities for efficiency improvements on their distribution systems, and that utilities should be investing in those opportunities, though many caution that the cost-effectiveness of such investment is not always clear. • Two biggest barriers noted were capital availability and cost-effectiveness – others included low priority for DE, knowledge about opportunities, personnel constraints, system constraints, and regulatory constraints.

DE Tools Evaluation Findings:
Many tools available; ranging from system simulation tools to statistical regression
Simulation tools/engineering assessment used primarily for project feasibility C/E evaluation
Some utility experience with RTF Protocol #1 but not many meeting exact requirements
Several cited use of RTF Simplified VO M&V Protocol to estimate/report savings.
AMI integration provides new, less expensive data collection / VO opportunities
CVR integration with Distr. Management Systems (DMS) now on the market.
