Western Australia Distributed Energy Resources Orchestration Pilot (Project Symphony)

closed

The Western Australia Distributed Energy Resources Orchestration Pilot is piloting the orchestration of customer-owned distributed energy resources (DER) such as rooftop solar, batteries and major appliances to participate in a future energy market. The Western Australia Distributed Energy Resources Orchestration Pilot project acknowledges that one in three households in Western Australia (WA) has rooftop solar, equivalent to almost 2 gigawatts of renewable energy generation. Collectively, this represents the largest source of electricity generation on the South West Interconnected System (SWIS).Growth in consumer-owned DER will increase further in the years ahead as more solar systems with integrated battery storage come online. However, the widespread uptake of rooftop solar creates challenges and opportunities for the delivery of electricity.A high proportion of decentralised, unmanaged DER poses a risk to the stability of the WA power network when an excess of local rooftop solar generation greatly exceeds the demand for electricity at certain times of the day. Project Symphony will orchestrate customer DER to not only overcome the technical challenges to the electricity network but also enable DER participation in future energy markets to unlock greater benefits to customers.
