This is the world's first overhead wind power system capable of generating energy in megawatts.

The project inaugurated by China in Yibin, Sichuan province, is the S2000 Stratosphere Airborne Wind Energy System (SAWES), also known simply as S2000.

It is the world's first megawatt-scale airborne wind energy system designed for urban use. It was successfully tested on January 5, 2026, reaching an altitude of 2,000 meters, generating 385 kWh in 30 minutes and connecting to the electrical grid.

This floating system (like a large airship or balloon with internal turbines) harnesses stronger and more stable winds at high altitudes, with an estimated maximum power output of approximately 3 megawatts per unit. For example, it can charge about 30 electric vehicles from zero to full in just one hour of operation.

Developed by SAWES Energy Technology (Beijing), it is an evolution of the previous S1500 model (tested in 2025 in the Xinjiang desert). The S2000 is better suited to urban environments, with quick assembly (in a few hours) and transport in containers.
