A competition about "height" is taking place in the mountainous areas of Xingren City, Guizhou Province. When the news of Gezhouba Electromechanical Company winning the bid for the Sankeshu Wind Farm project for 245 million yuan came out, the entire industry's attention turned to this undulating mountain range - here, 15 wind turbines will stand at an altitude of 140 meters, using 6.25-megawatt giant blades to capture the wind that only male eagles can touch.

This is not just an ordinary winning bid. At the strategic turning point of onshore wind power shifting from the "Three North" plains to the southwestern mountains, this project is defining a new technological standard: higher, larger, and more refined. When traditional wind power development encounters the triple dilemma of complex terrain, difficult transportation, and ecological sensitivity, the combination of 140 meter hub height and 6.25-megawatt large units is becoming the "golden key" to solving the problem of mountain wind power.

New standard configuration for high tower tube and large machine

The technical parameters of the Three Trees Wind Farm are like a declaration of the evolution of onshore wind power. 15 wind turbines with a single capacity of 6.25 megawatts, all with hub heights reaching 140 meters - this is equivalent to a building over 40 stories tall standing steadily on a rugged mountain ridge.

Why are you so obsessed with heights? The answer is hidden in the wind. The wind turbulence near the ground is complex and the wind speed is unstable, while at an altitude of 140 meters, it is another world. The wind speed is higher and the airflow is more stable there, which can truly unleash the power generation potential of large capacity units. In mountainous areas where land conditions are limited, achieving greater installed capacity with fewer parking spots has become an inevitable choice to improve project economics.

Solving the difficult problem of complex mountainous terrain

The southwestern mountainous areas are the last 'hard bone' in China's wind power development. There is no flat and vast "Three Norths", only continuous mountains and narrow construction surfaces. Transporting wind turbine blades up a hundred meters long mountain is itself an extreme engineering challenge.

Behind the 245 million yuan contract is a comprehensive inspection of Gezhouba Electromechanical's ability to construct in complex terrains. From equipment transportation to lifting operations, from ecological protection to grid connection, every link requires more refined planning than plain wind power. Once these challenges are overcome, it means obtaining the passport to enter the vast market in Southwest China.

The project in Xingren, Guizhou is just a piece of the puzzle in the grand layout of the Southwest Water Scenery Integrated Base. With the strategic tilt of the "14th Five Year Plan" towards the southwest region, it is becoming the next main battlefield for China's renewable energy after the "Three Norths".

The annual on grid electricity consumption of 170 million kilowatt hours and the saving of 52500 tons of standard coal - the emission reduction data after the completion of the Three Trees Wind Farm outline the green value of mountain wind power. For Gezhouba Electromechanical, winning the bid for the 245 million yuan project is not only an increase in performance, but also a competitive advantage in the new round of technology competition. When the whistle blows in the second half of the industry, only those who can handle complex environments and achieve higher cost-effectiveness can truly stand firm.Editor/Gao Xue
