  • About us
    • Who we are A dependable partner to millions of Australians, we’re the backbone that energy suppliers rely on.
    • Our approach By leading the transition to a clean energy future, we aim to make a better power system for Australians.
    • Leadership Our directors and executive team have a wealth of combined experience across the energy industry.
    • Our history Since the 1950's, our network has developed to meet the growing needs of energy consumers.
    • Network Our network extends throughout NSW and the ACT, with connections to Queensland and Victoria.
    • Regulatory framework In the National Energy Market, our operations are governed by a number of institutions.
    • Suppliers We invest in building sustainable working relationships with all our procurement partners.
    • Our culture We focus on making services affordable, prioritising safety, and delivering for our customers.
    • Debt Investors We provide information for our registered debt investors
  • Safety
    • Community safety To ensure the safety and reliability of our transmission network, we routinely inspect our transmission poles, towers and lines to assess their condition.
    • Network inspections and maintenance near you Transgrid undertakes ground and aerial inspections to identify safety risks to the network and undertake any necessary maintenance to keep the network safe and reliable.
    • Working near underground cables Different requirements apply to work taking place near underground transmission cables. A Before You Dig (BYD) search is essential prior to any excavation work taking place.
    • Managing bush fire risk Annual inspections are an important part of our comprehensive maintenance program, and ensure the transmission network is safe for our staff and the community.
    • Working safe The safety and welfare of our people, delivery partners, and the broader community is our highest priority.
  • Community
    • Landowners Our community engagement teams consult with landowners and residents across our network and along proposed project routes.
    • Network inspections and maintenance near you Transgrid undertakes ground and aerial inspections to identify safety risks to the network and undertake any necessary maintenance to keep the network safe and reliable.
    • Social licence program We are undertaking a program of initiatives to build social licence and deliver better outcomes for impacted communities. We have a range of current key work streams.
    • Stakeholder engagement We are dedicated to continuously improving our engagement with key stakeholders to support our decision making and deliver community benefits.
    • Cultural heritage and reconciliation Implementing our Reconciliation Action Plan contributes to creating a more equitable future.
    • Community Partnerships Program Our Community Partnerships Program benefits areas where our assets are located or under development.
    • Sponsorships & Partnerships Promoting diversity and inclusion is a key component of our sponsorship program.
    • Transgrid Discovery Hub The Transgrid Discovery Hub allow a consistent and accessible point of connection with community, landowners, and businesses in the Wagga and surrounding areas.
  • Energy
    transition
    • Beyond the Transition: Powering the Next Wave of REZs For many decades, planning for electricity networks was based on relatively predictable and stable patterns of demand and supply. But the energy transition has changed that, reshaping where and how energy is both produced and used.
    • 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.
    • How upskilling Australians could be the gamechanger in accelerating our clean energy transition We explore the skill challenges in clean energy industries, the government's initiatives to address the shortage, the benefits of investing in clean energy skills, and Transgrid's commitment to creating job opportunities in the renewable energy sector.
  • Projects &
    innovation
    • EnergyConnect EnergyConnect is a critical project that will lower power bills for homes and businesses.
    • HumeLink A new 500kV transmission line will carry electricity to customers from new generation sources.
    • Victoria to NSW Interconnector West VNI West is a core component and priority project in AEMO’s 2022 ISP, which confirms the need for short- and longer-term investment to increase the transfer capacity between the states.
    • Hunter Transmission Project A new overhead 500kV transmission line spanning around 100 kilometres between Bayswater in the Upper Hunter and Olney in the Lower Hunter.
    • Mount Piper to Wallerawang Transmission Line Upgrade Project The Project will strengthen and reinforce the grid in the State’s Central Tablelands region, helping to ensure that power from the Central-West Orana Renewable Energy Zone (CWOREZ) can be reliably transmitted to consumers.
    • System Security Roadmap Operational Technology Upgrades This transformation is driving a substantial increase in information and analysis requirements across our operational control and operational planning functions.
    • Central West Orana Renewable Energy Zone The NSW government has developed a plan to establish five Renewable Energy Zones (REZs) to increase energy generation, reduce carbon emissions, and help deliver lower wholesale electricity costs to consumers.
    • Waratah Super Battery Enabling Works The project will allow increased transmission of energy to meet demand in the Sydney, Newcastle, and Wollongong regions, following the reduction in supply due to the planned closure of Eraring Power Station.
