4 Flexible Trading Arrangements

4.1 Goal

The Unlocking CER Consumer energy resources Benefits Through Flexible Trading rule change facilitates flexible trading with multiple energy service providers at large customer premises, optimize Customer A customer is a registered participant that purchases electricity supplied through a transmission or distribution system to a connection point. Retailers and end users who buy electricity in the spot market must be registered as market customers. Energy The unit must be a generator for the service type: ‘energy’. Loads cannot bid for mandatory restrictions capacity. Resources (CER) flexibility for small customers, and measures energy flows from in-built technology such as streetlights and EV Electric Vehicle chargers.

The key objective for this project is to implement the Flexible Trader See Relevant Rules or Procedures Model 2 (FTM2), allowing end users to establish private metering arrangements for controllable resources managed by separate financially responsible Market Participants (FRMPs), and to introduce minor energy flow metering to accommodate non-traditional metering installations within PMAs.

FTA introduces Secondary Settlement Points (SSPs) allowing for metering and settlement of Consumer An end use customer of energy. Energy Resources (CER) behind the premises connection point.
