Western Sydney, Australia is undergoing significant growth and development, focusing on establishing a 'Metropolis of Three Cities' and achieving ambitious renewable energy goals. Endeavour Energy's network area encompasses several priority growth areas, transforming agricultural regions into urban communities.

To power these communities, at least 25 new zone and transmission substations are required within the next decade. A stop-and-reset approach was utilized to realize significant time and cost savings, delivering this critical network infrastructure without increasing the existing employee headcount or contracting out significant work packets.

Following an intensive R&D project, several IEC61850 digital substations have been delivered, allowing for parallel work processes, efficient delivery, non-intrusive fault-finding capabilities, and employee upskilling opportunities, leading to increased satisfaction.

Standardization was pivotal in ensuring consistency and ease of implementation across multiple substations. This approach facilitated agile and efficient design processes that accommodate future augmentations without disrupting existing configurations.

The presentation underscores the importance of integrating modern digital substation technology while maintaining operational reliability and safety, paving the way for more resilient and flexible electrical infrastructure in rapidly growing urban environments.
