Approximately 1,150 to 1,780 employees (source: zoominfo.com). Revenue of $887 million in FY 2023 (source: rocketreach.co).
What They Do
TransGrid's primary focus is on operating the high-voltage electricity transmission network across New South Wales (NSW) and the Australian Capital Territory (ACT). This extensive network spans over 13,085 kilometers of transmission lines and includes 128 substations operating at various voltages, including 500 kV, 330 kV, 220 kV, and 132 kV. The company connects a diverse range of stakeholders, including generators, distributors, and 20 direct-connect customers such as Endeavour Energy, Ausgrid, Evoenergy, and Essential Energy, while also facilitating the integration of renewable energy sources like wind and solar (source: wikipedia.org). Additionally, TransGrid operates a telecommunications network that exceeds 4,000 kilometers, primarily utilizing Optical Ground Wire on its transmission lines.
TransGrid offers a variety of products and services, including high-voltage transmission network management, connections for renewable generation, and telecommunications infrastructure. The company also provides non-regulated services through its Transgrid Services Group (TSG), which was established in 2018 to enhance infrastructure and telecom delivery (source: transgrid.com.au). Target markets include the National Electricity Market (NEM), serving NSW and ACT, with interconnections to Queensland and Victoria. The company emphasizes grid stability, particularly as the energy landscape transitions towards renewable sources.
As Australia's largest transmission network operator, TransGrid differentiates itself through its extensive infrastructure scale and innovative technologies. This includes the deployment of synchronous condensers for inertia and voltage control, which are essential for accommodating higher levels of renewable energy penetration. The company also invests in innovation funds, such as the $4.7 million Demand Management Innovation Allowance (DMIA), aimed at supporting flexible loads and virtual power plants (VPPs), alongside advancements in drone inspections and control room technology upgrades (source: smartcitiestech.io).
Projects & Track Record
TransGrid has been involved in several notable projects that highlight its commitment to enhancing the electricity transmission network. One significant project is the South Australia portion of EnergyConnect, which spans 200 kilometers between Robertstown and the NSW/SA border, completed by ElectraNet in December 2023. This project is part of a larger 700-kilometer interconnector that aims to unlock 1,800 MW of clean energy across NSW, South Australia, and Victoria's renewable zones, supported by $295 million in financing from the Clean Energy Finance Corporation (CEFC) and creating approximately 1,700 construction jobs (source: cefc.com.au).
Ongoing major projects include the full EnergyConnect initiative, which will cover a total of 900 kilometers, and the installation of synchronous condensers at five sites across NSW, contracted with GE Vernova in November 2025. These installations are crucial for providing grid inertia, voltage control, and fault current capabilities to replace functions previously served by coal. Additionally, TransGrid is upgrading its control room technology to enhance dynamic high-voltage operations and is utilizing digital twin simulations for grid scenarios through a partnership with AgenticGrid.ai, funded by the DMIA (source: gevernova.com).
TransGrid's key clients and partnerships include GE Vernova, Elecnor Australia, ElectraNet, and the Clean Energy Finance Corporation, as well as direct connections with major energy distributors like Endeavour Energy, Ausgrid, Evoenergy, and Essential Energy. The company's geographic presence is robust, covering NSW and ACT fully, with interconnections to Queensland and Victoria, and ongoing expansion efforts through projects like EnergyConnect into South Australia's renewable zones (source: wikipedia.org).
Recent Developments
In November 2025, TransGrid signed a significant contract with GE Vernova for the installation of synchronous condensers at five sites in NSW, aimed at stabilizing the grid during the transition from coal to renewable energy sources (source: gevernova.com). Earlier, in September 2025, the company launched a $4.7 million Demand Management Innovation Allowance (DMIA) fund, which awarded funding to AgenticGrid.ai for developing grid digital twins that simulate the integration of renewables and weather events (source: smartcitiestech.io). Additionally, Brett Redman was appointed as the Chief Executive Officer, marking a significant leadership change within the organization (source: zoominfo.com).
ElectraNet successfully completed the South Australia portion of EnergyConnect in December 2023, which is a critical advancement for TransGrid's 700-kilometer segment in NSW, further enhancing the interconnectivity of the electricity grid (source: cefc.com.au). Furthermore, TransGrid has initiated a control room technology uplift program to improve operations for the clean energy grid and has established community partnerships that offer grants of up to $10,000 in Broken Hill and Far West NSW until December 7, 2024 (source: transgrid.com.au). Notably, the company's new headquarters at 180 Thomas St, Haymarket, Sydney, has achieved a 6-star rating, making it the first project in NSW to reach such a standard (source: thefifthestate.com.au).
Working There
TransGrid offers a diverse range of roles across various departments, including Engineering & Technical, Operations, Information Technology, Finance, Marketing, Legal, and Human Resources. The company employs approximately 300 individuals in Engineering & Technical, 273 in Operations, 200 in Information Technology, and 185 in Finance, among others, with executive leadership comprising CEO Brett Redman, CFO Nadine Lennie, and Executive General Manager Network Marie Jordan (source: zoominfo.com). Hiring primarily occurs at the Sydney headquarters, located at 180 Thomas St, with additional offices in Newcastle, Orange, Tamworth, Wagga Wagga, and Yass, employing a total of 979 individuals in Australia and a small number in Europe and North America (source: wikipedia.org).
The company culture is reflected in its 6-star rated Haymarket headquarters, which emphasizes efficiency and innovation, aligning with the company's commitment to clean energy transition and stakeholder engagement. TransGrid actively collaborates on innovation projects through the DMIA and engages in community partnerships, such as providing grants to local initiatives (source: thefifthestate.com.au). While specific benefits are not extensively documented, the leadership under People & Culture head Stephen McSweeney suggests a structured approach to human resources support (source: wikipedia.org).
