A Beijing-based energy company has taken a major step toward commercial airborne wind power after completing the maiden flight and grid-connected power generation test of its megawatt-class system in Southwest China.

The test took place on Sunday in Yibin, Sichuan Province, where the floating wind power platform rose to about 6,560 feet (2,000 meters) and successfully delivered electricity to the grid, as reported by China’s state-backed Global Times.
