Synergy has inked contracts with Evergen and Rheem to offer third-party distributed energy resources (DER) for the Project Symphony pilot.

In a statement, the Western Australian Government said the $35.5 million project would distribute the 900 DER assets’ renewable energy to 500 homes and businesses in Perth’s Southern River area.

Energy Minister Bill Johnston said Project Symphony is an innovative strategy for coordinating Western Australia’s future energy system as Western Australians embrace rooftop solar at an unprecedented rate.

“Synergy’s contractual relationship with Evergen and Rheem presents a major step forward towards a distributed energy resources future, where sustainability is key for customers and stability is provided to WA’s power system,” Minister Johnston stated.


According to the Western Australian Government, the agreements will allow Synergy to incorporate consumer DER from Evergen and Rheem into Project Symphony, adding to the roughly 600 assets previously committed to the pilot.

Rooftop solar, batteries, and electric cars, typically found at homes or businesses and may create or store renewable electricity, are included in DER.

Synergy gathers extra electricity from DER to create a “virtual power plant” that can feed into the network, similar to a conventional power plant.

Project Symphony is a cooperation between the Western Australian Government, the Australian Government, Synergy, Western Power, and the Australian Energy Market Operator (AEMO).

The Western Australian Government has allocated $19.3 million to the pilot, a key deliverable of the Distributed Energy Resources Roadmap and Energy Transformation Strategy.

“We expect by 2030, 50 per cent of households will have rooftop solar systems,” Minister Johnston said.
