6. SLIDE 6 Power of Choice – Metering Competition REMAINING QUESTIONS/FEEDBACK Can an obligation on the MC under rule be passed on to a service provider? At some point we need to consider what will happen when the DB undertakes a site visit for a faulty type 5/6 meter. It is unlikely that the MC will have sufficient afterhours people on call (who can reach each site) - customers cannot be left off supply (e.g. especially life support, sensitive load etc.) – so what will happen? Diagram 3 should recognise billing process between MC and the DNSP/Other Authorised Parties for services

PROCESS FLOWS FOR SERVICES Business process maps for the following services have been updated based on the participant feedback collected during and after the previous workshop: o New Connections (Not NSW) o New Connections (NSW) o Manual Re-energisation and De-energisation o Remote Reconnection and Disconnection This is only a draft version of the process maps to stimulate discussion in the workshop to be able to identify changes to roles and retail market business processes as a consequence of the MC rule change.
