Battery projects in Western Australia
Updated
Battery storage in Western Australia is being driven by two distinct markets. In the SWIS, grid-scale batteries are playing a growing role in system security and in firming renewable generation as the state's clean energy target drives new investment. In remote areas and at mine sites, batteries are a core component of hybrid/co-located energy systems replacing or reducing diesel generation – often at significant scale. Synergy's Project Symphony and related initiatives reflect how the state is thinking about storage at the system level, while the resources sector is increasingly treating battery-backed renewables as an operational and cost-management priority.
