Overview
- The S2000 SAWES, an airship‑like platform from Beijing Linyi Yunchuan Energy Technology, completed a brief grid‑connected flight over Yibin in Sichuan Province.
- The system rose to roughly 2,000 meters and delivered 385 kWh during a test lasting about 30 minutes.
- Measuring about 60 by 40 by 40 meters, the platform generates power aloft and transmits it to the ground through a tethered cable for grid integration.
- The prototype is described as megawatt‑class, with press materials reporting a maximum rated capacity of 3 megawatts.
- Planned next steps include longer‑duration and higher‑output runs plus optional communications and monitoring payloads, with major hurdles remaining in airspace certification, extreme‑weather resilience, launch and retrieval, and proving year‑round economics.
