China’s first 13 MW offshore wind turbine prototype, developed by Dongfang Electric, was launched on Feb 22.
The turbine, designed for the high-wind-speed Fujian and Guangdong offshore, has a 211m rotor diameter and 35,000 rotor swape area. On-time of the machine could reach over 4100 at a wind speed of 10m/second. The new model is an upgrade from the firm’s first-of-its-kind 10MW turbine (185 rotor diameter.)
Dongfang Electric said the product achieved a local production rate of 90%. The 13MW turbine could help wind farms significantly reduce construction costs (est. reducing ¥500m for a 1GW wind farm using 10MW turbines. )
Energy Iceberg: the impressive milestone further cements DEC’s leading role in China’s offshore wind market. The firm has been the first in China to launch a 10 MW turbine with local IP. Several other wind OEMs have announced plans to advance the 11-15MW turbine R&Ds. So far, most efforts have yet to produce the final results.
Dongfang Electric is one of China’s key state-owned electric equipment manufacturers, with long-standing turbine technology research. The milestone underscores a shift in China’s wind market, where the large state-owned companies are becoming the dominant players in recent years. The milestone is expected to spur other OEMs to increase R&D spending.
