China’s State Grid Corporation has unveiled the world’s largest grid operation and control system for renewable energy, a major step in addressing the global challenge of integrating renewables into large-scale power networks.
Announced during the 2025 International Forum on Energy and Power Transformation in Beijing (May 19–20), the system was developed entirely in-house and is capable of managing daily renewable output fluctuations of up to 360 gigawatts. It positions State Grid as the world’s largest grid operator in terms of renewable energy integration.
With renewables now making up more than 40% of China’s total installed power capacity, the new system was designed to ensure the safe and stable operation of the national grid. It currently spans more than 60,000 substations and hundreds of thousands of renewable power sites across the country. Angela Wilkinson, Secretary General and CEO of the World Energy Council, described the achievement as “remarkable,” noting: “China’s energy transition prioritizes security. Its vast and intelligent transmission and distribution systems link supply and demand in real time — a model for large-scale energy transformation.”
The system supports renewable capacity scaling up to 1.41 billion kilowatts and aims to boost China’s renewable utilization rate to 96.1%. Developed by State Grid, it combines real-time simulation, economic dispatch, and fault prevention capabilities.
Crucially, it enables fast, efficient coordination between generation, grid infrastructure, energy storage, and consumer demand — even amid massive daily fluctuations. This solves a long-standing technical barrier to operating ultra-large renewable-powered grids safely, economically, and with low carbon emissions.
