At Transgrid, we play a crucial role in delivering safe, reliable, and sustainable energy to millions of Australians. Operating over 13,000 km of high-voltage transmission lines and 128 substations across NSW and the ACT, we connect electricity generators to the distribution network powering homes, businesses, and communities. As Australia accelerates its energy transition, the work we do has never been more significant.
About the opportunity
As a Senior Network Planning Engineer, you will take a lead role in planning, modelling and analysing the transmission network and its interfaces with distribution networks. You will develop network models, assess network and non-network solutions, prepare robust technical reports and provide recommendations that balance technical, commercial, risk and performance requirements. Working closely with Network Service Providers, generators and internal stakeholders, you will coordinate joint planning activities and help shape the stronger, smarter grid needed to support Australia's clean energy future.
What you'll do
Lead short, medium and long-term modelling, forecasting and network planning analysis to inform system development
Manage and coordinate planning related work requests between Transgrid and network service providers to support project delivery
Lead and contribute to the Transmission Annual Planning Report (TAPR)
Author and review technical reports, option studies, and stakeholder presentations
Drive the development of power system analysis methodologies, models, and processes
Provide expert advice on complex technical enquiries and emerging technologies
Support and manage key system tools (PowerFactory, PSS/E) and Python-based applications




Stay across changes in the National Electricity Market, standards, and legislation
Build strong industry relationships and coordinate joint planning activities with AEMO, DNSPs, generators, regulators and internal stakeholders
What you'll bring
At least 5 years' experience in electricity network planning, with demonstrated progression into a senior-level role
Strong understanding of electricity transmission and distribution networks, the NEM, planning standards and relevant legislation
Solid technical capability to perform, interpret and clearly communicate network simulations and power system studies
Demonstrated senior level experience, strategic thinking and the ability to align outcomes across multiple organisations
Strong written and verbal communication, stakeholder management and technical report writing skills
Ability to manage competing priorities and deliver high quality outcomes within required timeframes
Why this role?
The energy transition does not happen in theory. In this role, your technical judgement and critical thinking will directly influence how Australia's power system evolves. You will help solve complex network challenges, improve the way we plan for the future and make decisions that will shape reliable infrastructure for decades to come.
