NSW has changed the rules that determine when the Independent Planning Commission becomes the consent authority for state significant development, with significant implications for renewable energy, resources and standalone battery projects.

The changes are contained in the State Environmental Planning Policy (Planning Systems) Amendment (Independent Planning Commission) 2026, published on 18 August 2026. Some changes took effect immediately, with further changes commencing on 1 November 2026.

Today marks one of the most significant changes to the NSW planning system in recent years, with the Development Coordination Authority (DCA) officially commencing its expanded role as the central coordination point for NSW Government agency referrals.

Much of the discussion around the reforms has focused on improving the assessment of local development applications and supporting the delivery of new housing. However, there are also important implications for state significant development (SSD) projects that proponents, consultants and project teams should understand.

While the core SSD assessment pathway remains largely unchanged, the way government agencies contribute to assessments is evolving.
