Welcome to Transgrid’s System Security Roadmap

Transgrid is building NSW’s new energy superhighway, while ensuring the safety, reliability and security of our existing system – which powers millions of homes and businesses.

This Roadmap outlines our three-pillar plan to transform the state’s power system and ensure the secure operation of the grid, at up to 100% instantaneous renewables, over the next decade. It covers:

  • Energy Reliability – How we will develop large-scale transmission infrastructure to support new renewable generation and storage as coal generators retire.
  • System Security – How we will deploy system security infrastructure and services to keep the grid operating within a safe technical envelope.
  • Operability – How we will develop our people, processes and tools to meet the increased volume and complexity of work to plan, manage and operate a grid powered by renewables.

Let’s work together to make a better power system for Australians.
