China's floating wind turbines take flight to power the national grid
A groundbreaking renewable energy project in China has reached a major milestone. The SAWES Type S2000, a floating wind turbine system, successfully connected to the power grid in January 2025. This marks the first time a megawatt-class airborne wind power system has delivered electricity to the national grid.
The project, known as Stratospheric Airborne Wind Energy Systems (SAWES), is a collaboration between Tsinghua University and Beijing SAWES Energy Technology Co., Ltd. It uses helium-filled aerostats to lift turbines high into the sky, reducing material use by up to 90% compared to traditional wind turbines. The latest prototype, the S2000, measures 60 metres long and 40 metres high and wide, with 12 turbines generating a total of 3 megawatts of power.
The system can automatically rise or descend to find the strongest winds, potentially boosting energy output. In its first test, it produced 385 kilowatt hours of electricity. However, no independent studies have yet verified its performance at altitudes above 1,000 metres.
Future plans include expanding the system with more communication and monitoring devices, forming an 'AeroMatrix' network. While the technology shows promise, its immediate applications are likely to be in remote areas, off-grid energy supply, and emergency power situations.
The SAWES project aims to contribute clean energy to the grid, helping to reduce reliance on fossil fuels. With its smaller visual and noise impact, it offers an alternative to conventional wind farms. The next steps will depend on further testing and validation of its high-altitude capabilities.
