Electricity market transformation

Energy used to flow from large power stations through our networks. Now, it moves in two directions as our customers generate energy with solar panels and store it in batteries.

Our role as a Distribution System Operator (DSO) expands on our traditional services. We have three main functions: 

1.  Enable customer choice: We connect rooftop solar, home batteries and electric vehicle chargers to our network. This allows excess solar to be shared with neighbours or the wholesale electricity market. 

2.  Facilitate new competition: We signal network conditions so emerging trader services (such as electricity aggregators) can operate in the market. This provides new opportunities for customers to participate in the market and benefit.  

3.  Maintain system security and network stability: We do this in coordination with the Australian Energy Market Operator (AEMO). 

All customers should be able to benefit from the changing market. 

Those who invest in solar, batteries or other technologies can receive financial benefits. But there can be many reasons why customers choose not to take part. This could include:  

•  upfront cost of technology 
•  the lack of a suitable roof for solar  
•  challenges associated with living in apartments or rental properties. 

The growth of renewable energy is offering new ways for all energy users to benefit. For example, the popularity of rooftop creates an abundance of energy during the day. This underpins new retail offers that provide free daytime energy windows.

The growth of battery storage is also helping to deliver lower network tariffs by avoiding the need for costly upgrades.
