How AEMO Plans to Ensure Grid Stability in a Renewable Future
As Australia transitions toward a renewable energy-dominated grid, grid stability becomes a critical concern. The Australian Energy Market Operator (AEMO) is implementing strategies to ensure that increasing levels of wind, solar, and battery storage integrate smoothly into the electricity market. By leveraging advanced technologies, emergency solar management, and comprehensive planning, AEMO aims to maintain system reliability and affordability for Australian consumers.
Enhancing System Strength with Advanced Technologies
One of AEMO’s primary goals is to enhance system strength as the grid shifts away from traditional synchronous generators toward inverter-based renewable resources. Historically, coal and gas-fired power stations provided inertia and system strength, stabilizing voltage and frequency fluctuations. However, as these generators retire, the grid requires alternative stabilizing technologies to maintain reliability.
AEMO is prioritizing the deployment of grid-forming inverters, which can replicate the inertia and frequency support traditionally provided by fossil fuel generators. These advanced inverters actively regulate voltage and frequency while improving overall power quality. AEMO's 2024 Transition Plan for System Security states, "Grid-forming inverter technology is a crucial component of the future power system, allowing increased renewable energy integration without compromising stability."

In addition to grid-forming inverters, AEMO is exploring the role of synchronous condensers—large spinning machines that mimic the stabilizing effects of traditional power stations. These devices help prevent voltage instability, especially in regions with high renewable energy penetration.
Battery storage is another essential tool in AEMO’s plan. Large-scale projects like the Victorian Big Battery and Waratah Super Battery are designed to provide fast frequency response, ensuring that power imbalances are quickly corrected when fluctuations occur. With ongoing research, investment, and grid trials, AEMO is positioning Australia to lead the world in integrating renewables while maintaining a secure and stable energy network.
Implementing Emergency Solar Management
Australia has one of the highest rooftop solar adoption rates in the world, with over 3.5 million solar PV systems installed nationwide. While this is beneficial for sustainability and energy affordability, it creates grid challenges during periods of excess generation. When electricity supply outstrips demand—especially on sunny, mild days—grid stability can be threatened.
To address this, AEMO has introduced Emergency Solar Management (also called Distributed Photovoltaic Management, or DPVM). This initiative remotely curtails rooftop solar output when necessary to prevent network overloads and maintain system security. According to AEMO, "Emergency Solar Management ensures that minimum demand does not reach levels where it risks network security." (AEMO)
A similar measure is already in place in South Australia, where dynamic export limits allow authorities to adjust rooftop solar exports based on real-time grid demand. Additionally, Virtual Power Plants (VPPs) are emerging as a demand-side solution. VPPs coordinate thousands of household solar and battery systems, aggregating their capacity to help stabilize the grid during peak demand periods.
By integrating these measures, AEMO is ensuring that rooftop solar can continue to grow while avoiding grid instability and preventing forced blackouts. These strategies will be essential as distributed solar generation continues to expand.
Planning for a High-Renewable Future
AEMO’s Integrated System Plan (ISP) outlines a roadmap for Australia’s energy transition, forecasting that by 2050, renewables will provide over 80% of the nation’s electricity. However, successfully integrating these resources requires strategic investments in transmission, energy storage, and new grid infrastructure.
One major challenge is the geographical distribution of renewable energy. Solar and wind farms are often located far from population centers, requiring significant transmission network upgrades. AEMO has identified Renewable Energy Zones (REZs) as key investment areas where renewable generation can be efficiently delivered to consumers. The HumeLink and VNI West projects are two major transmission upgrades that will help transfer electricity from renewable-rich regions to demand centers. (AEMO)
Energy storage will also play a crucial role. Pumped hydro projects, such as Snowy 2.0, will provide long-duration energy storage, ensuring that surplus renewable energy can be stored and dispatched when needed. Meanwhile, battery energy storage systems (BESS) will offer rapid-response grid support, addressing frequency fluctuations and reducing the need for gas-fired peaking plants.
AEMO is also investing in AI-driven forecasting tools that improve real-time energy predictions, helping the market adjust to supply and demand fluctuations more efficiently. By combining technological advancements with strategic policy and market reforms, AEMO is ensuring that Australia’s transition to renewables is both economically sustainable and technically viable.
