Building a better power system through system security and operability
With the closure of Liddell power station in April 2023 and the planned 2025 closure of the Eraring Power Station, Transgrid is on the frontline of making profound changes to maintain system strength and ensure the safe and secure operation of the power system.
Fostering the clean energy workforce of the future
The shift to a clean energy future isn't just about changing how we generate electricity—it's also about creating job opportunities, upskilling our workforce, and strengthening our regional economy.
