Axcentium has supported major transmission, renewable, and energy infrastructure initiatives across Australia. Our experience spans strategic advisory, technical due diligence, power system modelling, and project delivery support for some of the country’s most significant energy projects.
Axcentium provided engineering review and strategic advisory services for the 1500MW Marinus Link HVDC interconnector spanning approximately 600km between Tasmania and mainland Australia. Services included transmission line design and route review, overarching power system architecture input, and integration advice into the National Electricity Grid. The engagement has evolved into ongoing strategic project management advisory support throughout the Design and Approvals phase of this nationally significant infrastructure project.
Axcentium conducted detailed technical studies assessing Virtual Power Plant (VPP) integration using redox flow battery systems in urban environments. The project evaluated voltage stability control, peak demand management, energy arbitrage, fast frequency response, and synthetic inertia capabilities. The VPP concept demonstrated significant capital expenditure reduction by increasing transmission and distribution system capacity without major infrastructure upgrades. The solution also incorporated integrated EV charging systems to further enhance network optimisation and grid reliability.
Under the Integrated System Plan (ISP), AEMO requires multiple new 300kV and 500kV interconnecting transmission circuits across Australia. Axcentium collaborated with AEMO to develop commissioning protocols and testing regimes for these large-scale AC interconnectors, including integration of a 2000MW pumped storage hydro facility. The work ensured safe, compliant, and technically robust commissioning of nationally critical transmission infrastructure supporting Australia’s evolving energy system.
Axcentium provided technical and strategic advisory services supporting the NSW Government’s Energy Infrastructure Plan and Renewable Energy Zone (REZ) development. The program delivers approximately 12GW of new transmission capacity, supports 3GW of firm capacity, and attracts significant regional investment. Axcentium’s advisory input contributed to transmission planning, renewable integration, and long-term infrastructure coordination aligned with Net Zero objectives and large-scale private sector investment.
Axcentium provided technical review and coordination with market bodies to support the commissioning of the 275MW Darlington Point Solar Farm. The engagement focused on grid connection compliance, system integration, and performance validation. As one of the largest solar facilities connected to the Australian power system, the project required detailed coordination to ensure technical robustness and regulatory alignment during commissioning.
Axcentium conducted advanced power system modelling using PSSE and PSCAD to support grid integration of the Yarranlea Solar Farm. The project addressed system strength limitations and stability issues affecting connection performance. Through detailed analytical review and technical advisory support, Axcentium enabled mitigation strategies ensuring reliable grid compliance and improved operational resilience for the project.
Axcentium provided technical advisory services supporting transmission asset valuation and economic modelling. The engagement included 30-year load and generation forecasting, capital program build-out review, operating cost assessment, and grid optimisation analysis. The work enabled informed investment decision-making through detailed evaluation of asset performance, capital efficiency, and long-term infrastructure sustainability.
Axcentium, in joint venture with Ahurei and Engevity, delivered a full feasibility study for a 3000MW off-grid renewable hydrogen system in the Northern Territory. The project integrates solar-powered hydrogen production with proprietary water generation technology, eliminating reliance on grid or external water sources. The system is designed for large-scale export capacity and represents an innovative approach to remote renewable energy infrastructure.
Axcentium is delivering Generator Performance Standard (GPS) studies for the 450MW Strontian Road Solar and BESS project. The work includes RMS dynamic simulation using PSS/E, EMT simulation using PSCAD, and power quality studies using PowerFactory DIgSILENT. The engagement ensures technical compliance, grid stability, and performance validation for inverter-based hybrid generation systems.
Axcentium is providing Generator Performance Standard (GPS) studies for the Lockhart 9.9MW Hybrid PV and BESS project. The scope includes RMS and EMT dynamic simulation, power quality studies, and inverter-based system performance validation using PSS/E, PSCAD, and PowerFactory DIgSILENT. The work supports compliant integration and reliable operation within the broader electricity network.
