en.Wedoany.com Reported - The first wind turbine of CGN's Ali Gaize 50 MW wind power project was successfully installed at 20:00 on July 13, at an altitude of 4,765 meters, setting a new altitude record for CGN's wind power project construction. This installation marks the project's official entry into the critical installation phase, taking a key step toward grid connection and commercial operation.
The installed turbine has a hub height of 110 meters, blade length of 94.5 meters, rotor diameter of 193 meters, and a swept area exceeding 29,000 square meters. The project adopts the SI-19050 turbine model, which is custom-designed for the ultra-high altitude environment of Ali at the 5,000-meter level, featuring strong plateau adaptability, robust core component configuration, high platform reliability, and outstanding power generation economy, ensuring long-term stable output.
This project is the first wind power project in the Ali region and a key cooperation project for 2025 under the state-owned central enterprises' initiative to support the high-quality development of China's Tibet. The planned total investment is 280 million yuan. The construction includes 10 wind turbines with a single-unit capacity of 5 MW, a 10 MW energy storage system, and supporting facilities such as a 110 kV step-up substation and power collection lines.
The installation site's altitude and construction difficulty set new highs for CGN's onshore wind power projects, facing challenges such as severe cold and oxygen deficiency, reduced mechanical efficiency, decreased lifting performance, and limited installation windows. The project team formed a dedicated task force, repeatedly reviewed and evaluated plans, conducted layered technical briefings and realistic emergency drills to strengthen technical support; established a 24-hour wind speed monitoring system to precisely seize favorable weather windows; optimized installation techniques, refined the segmented lifting process for tower sections, nacelle, hub, and blades, and enhanced coordination between crane operations and high-altitude work; strictly adhered to ecological red lines, standardized construction scope, strictly controlled dust, minimized ground disturbance, and protected the plateau ecosystem; implemented full-process safety closed-loop management with continuous on-site supervision and strict risk control. Through the collaboration of all construction personnel, the first ultra-high altitude wind turbine installation task in Tibet was successfully completed.
The project is planned to be connected to the grid by the end of 2026. Upon full-capacity operation, the annual power generation is expected to reach 180 million kWh, equivalent to reducing carbon dioxide emissions by approximately 150,000 tons, effectively filling the regional clean energy supply gap. In the next step, CGN New Energy Tibet Company will summarize and consolidate the experience of ultra-high altitude wind power construction, steadily advance subsequent construction, and continue to deeply cultivate Tibet's clean energy industry.
