In 2005, all of South Australia's electricity was supplied from fossil-fuel generation, mainly coal and gas. Fast forward to today, and about 70% of SA's energy is being supplied from renewable energy sources.

With a significant portion of this energy already supplied from large-scale wind and solar farms and through rooftop solar, and an increasing trend of battery installations and Virtual Power Plants connecting to the grid, we believe we are on track for renewables to supply 100% of SA's energy needs by 2028.

We continue to work to ensure we can support more rooftop solar, batteries and electric vehicles on our network, and believe a key to this is Distributed Energy Resource (DER) compliance. As a first step, getting this right for all small embedded generation (SEG) systems means we can:

• Ensure supply and reduce the risk of widespread power outages
• Provide all customers fair access to the network and unlock future potential for solar and batteries in SA
• Support continued DER uptake rather than constrain the solar exports as we have seen in other states, which contributes to the growth of the solar industry
• Better plan and operate the network to enable this future

Our solar industry plays a critical part in helping us achieve this goal, through the correct installation and commissioning of DER equipment. Over the past 18 months, we have been working closely with solar retailers and installers to build knowledge, awareness and skills to ensure everyone can be successful in achieving their DER Compliance requirements.

Our most recent solar industry webinar was attended by 81 participants, who were engaged and enthusiastic about the changes. If you are interested in finding out more about our DER Compliance program, read more about the consequences for DER non-compliance.
