2.  Opinion Dynamics was contracted to conduct a primary research effort to measure Market Participant perceptions of ERCOT’s performance with respect to meeting its responsibilities.  Results allow for comparisons between market perceptions and operational realities. Introduction

3. Three Phases: Methodology Phase 1: 9 in-depth interviews and 2 focus groups with ERCOT staff Phase 2: In-depth interviews with 17 Market Participants Phase 3: Survey of ERCOT’s Market Participants

4. ODC developed a sample of 1,157 unique Market Participants using the following lists provided by ERCOT staff:  Appropriate points of contact at market participant firms provided by MP’s via CSR’s  ERCOT Board members from 2003 and 2004  Current Committee members from 2003-04  Attendees of the 2003 IT forum Survey Sample

5. Response Rate 429 completed surveys from a sample of 1,157 Market Participants (37%) ERCOT Board Membersn=16 Committee Membersn=112 Market Participant Staffn=301 Classification of respondent based on self-selected descriptions – QA1

6. By Market Participant Firm Type Response Rate

7. Survey Approach: 10 point scale  Many questions based on a 10 point scale: 1-3 = negative response, 8-10 = positive response.  Mean responses will trend toward the middle of a 10 point scale – only those with passionate opinion are likely to provide a rating in top or bottom 3.  In general, mean responses of 6.6 or above are favorable ratings, 7.5 and above are extremely positive responses.
