The Wholesale Market Objectives are defined in the Wholesale Market Rules. They are:

1. to promote the economically efficient, safe and reliable production and supply of electricity and electricity related services in the South West interconnected system;
2. to encourage competition among generators and retailers in the South West interconnected system, including by facilitating efficient entry of new competitors;
3. to avoid discrimination in that market against particular energy options and technologies, including sustainable energy options and technologies such as those that make use of renewable resources or that reduce overall greenhouse gas emissions;
4. to minimise the long-term cost of electricity supplied to customers from the South West interconnected system; and
5. to encourage the taking of measures to manage the amount of electricity used and when it is used.
