China's domestically developed S4000 airborne wind power system completed full flight verification at a northwest test site, reaching a maximum operational altitude of 4,000m. An iterative upgrade to the S2000, the S4000 uses a new configuration with broadly improved performance, a 20-year design life, and compatibility with most domestic deployment regions and mainstream grid requirements. High-altitude wind power has been included in the national '15th Five-Year' renewable energy development plan; the successful S4000 trial fills a key engineering-application gap and increases China's high-altitude clean-energy supply capacity.
