[2][3] The disaggregated of the Hydro-Electric Commission resulted in the formation of three separate state-owned companies: Hydro Tasmania, which generates the power; Transend Networks, which transmits it across the state; and Aurora Energy, the retail arm, which sells and distributes it to customers.

The official launch of the product, due to the success of the trial, went ahead in May 2007 making Aurora Energy the first electricity retailer to offer the pre-payment option in South Australia.

In 2012, Aurora failed in its application to the Australian Energy Regulator for electricity price increases of 15.5% over the following 5 years for infrastructure investment and carbon tax implications.

Over the following years, a complete re-structure was undertaken, resulting in hundreds of redundancies throughout the business, from field worker level through to upper management.

Retail contestability was introduced for very large customers in 2006, and in 2007, 2008, 2009, and 2011, additional, progressively smaller consumers of electricity were opened up for competition with Aurora.
