Sany 10 MW Wind Farm in Inner Mongolia Hits Full Capacity, 99.9% Availability

The Huaneng Muchuan wind farm, situated on grassland outside Daban Town in Balin Right Banner, Chifeng, Inner Mongolia, has fully connected its 30 10 MW turbines to the grid. The project, a large-scale onshore wind development, uses Sany Heavy Energy's SI-230100 model, featuring 112-meter full carbon fiber blades and a 230-meter rotor diameter. Construction began in July 2025, turbine installation was completed in December of that year, and full grid connection was achieved on January 23, 2026. The farm passed a 240-hour trial operation and has entered stable power generation, with availability standing at 99.9% over the past three months. Each turbine's swept area exceeds 41,500 square meters, equivalent to about six standard football pitches, and at rated wind speed produces approximately 4 kilowatt-hours of electricity per rotation. For a 1,000-megawatt project, using 10 MW turbines requires only 100 units, compared with 167 for conventional 6 MW machines, a reduction of nearly 40% in turbine positions. This cuts supporting investments such as internal roads, box transformers and transmission cables by 15%, lowering the overall levelized cost of electricity by 8% to 10%. The model is suited to intensive development of large-scale wind and solar bases in desert and gobi areas; the National Energy Administration's 'Desert and Gobi Large Wind and Solar Base Construction Guide (2025 Revision)' explicitly prioritizes turbines of 10 MW and above. Market data show that as of July 2026, cumulative awarded capacity for 10 MW onshore wind turbines reached 43.27 GW, with nine manufacturers participating in tenders. The top three suppliers hold roughly a 75% market share, of which Sany Heavy Energy accounts for more than 30%, supported by its independent 10 MW technology platform. Yunda Co. ranks second and Dongfang Electric third. In late 2023, the first batch tender for 10 MW onshore units was launched by a Huaneng project in Heilongjiang, marking the industry's entry into the large-turbine era. By 2026, the 10 MW class had become the standard workhorse model for the Three North regions.
