V. Respondents

We name as respondents in this proceeding the three major electric IOUs: PG&E, SDG&E, and SCE, as well as the ESPs listed in Appendix D to this proceeding, and any other ESP or CCA that is registered to serve retail customers within the service territory of one or more of the three respondent investor-owned utilities. These respondents shall file comments in response to the questions listed in Appendix C to this OIR, except that the ESPs and CCAs may, but are not required to comment on the specifics of the "matrix" we discuss elsewhere in this decision. All other parties may file comments. We may add respondents when we commence the second phase of this proceeding, related to GO 66-C.
