From AC to DC: A New Power Era
Australia’s electrification is set to transform power distribution by transitioning from alternating current (AC) to direct current (DC) across various sectors, including buildings, depots, and facilities. This shift marks a pivotal change in how electricity is used nationwide.
Electric vehicles, solar systems, and data centres contribute significantly to the growing demand for DC power, challenging the traditional reliance on AC for long-distance electricity transmission. As a result, designing efficient power architecture is becoming increasingly important.
Tim Pratt, Vice President of Power Products at Schneider Electric, stated, “The shift from AC to DC should be understood as a practical infrastructure trend.” This transition aims not to replace AC entirely but to optimise power systems for specific applications.
Optimising Power Systems in Australia
Electric bus depots illustrate the benefits of converting power from AC to DC closer to the facility’s entry point. By doing so, the system reduces energy loss and enhances overall efficiency across the site.
In 2023, data centres are accelerating the shift to DC power due to high-density computing needs. Investments in AI infrastructure are advancing technologies that will also benefit sectors such as electric vehicle charging and smart buildings.
With a strong foundation in rooftop solar installations and increasing battery adoption, Australia is well-positioned for this transition. Integrating digital infrastructure will be crucial for managing energy demands effectively.
Managing load is essential, especially in critical environments like hospitals and public transport systems. Digital tools provide visibility and control, ensuring these systems can adapt to changing demands without straining existing infrastructure.
Schneider Electric plays a key role as an energy technology partner by offering the necessary hardware and software to support this transition. As Australia progresses, developing standards and evolving building designs will be vital to accommodate the growing use of DC power applications.
