Located in the desert regions of western Gansu province, the complex is situated near the city of Jiuquan, specifically within Guazhou County and near Yumen City. The area was selected for its abundant wind resources, facilitating the deployment of large-scale wind turbines in a relatively remote geographic setting.
Phased Construction and Capacity Expansion
Development of the wind power base proceeded in distinct phases, beginning with initial construction efforts around 2008 and 2009. The first major phase involved the installation of a 3800 MW capacity, marking the initial operational footprint of the project. This was followed by a second phase designed to expand the total capacity to 8000 MW. These early phases established the foundation for the complex’s growth, although utilization rates varied during the initial years of operation.
| Phase | Capacity (MW) | Status/Notes |
|---|---|---|
| Phase 1 | 3800 | Initial construction started 2008/2009 |
| Phase 2 | 8000 | Expanded capacity |
By 2015, the complex was operating at below 40% utilization of its then-current 8 GW capacity. At that time, plans existed to expand the total planned capacity to 20 GW. However, the immediate priority was addressing transmission constraints. In 2017, the 2,383 km long Jiuquan - Hunan HVDC transmission line entered service. This critical infrastructure project connected the remote wind farms to the Hunan regional grid, enabling more efficient utilization of the generated electricity.
Following the transmission improvements and subsequent construction delays, the latest phase of construction was completed, bringing the total generation capacity of the Gansu Wind Farm Project to 10 GW. This final expansion marked the culmination of years of development, integrating numerous wind farms and turbines across the Guazhou and Yumen localities. The project remains operational, serving as a key component of China’s renewable energy portfolio in the northwest region.
How does the Gansu Wind Farm manage grid integration?
The integration of the Gansu Wind Farm into the Chinese national grid required significant technical infrastructure to manage the intermittency of wind power and the distance to major consumption centers. Early operational challenges highlighted the limitations of the regional transmission grid, which initially imposed a capacity limit of 1.5 GW. This constraint led to substantial curtailment, where generated power was lost because the grid could not absorb the full output. In 2015, the complex operated at below 40% utilization of its then-current 8 GW capacity, illustrating the severity of the integration bottleneck before major transmission upgrades were completed.
Transmission Infrastructure
To address these limitations, China implemented the Jiuquan - Hunan HVDC transmission line, a 2,383 km long corridor that entered service in 2017. This high-voltage direct current link connected the remote desert-based complex to the Hunan regional grid, significantly enhancing the ability to transport power over long distances with reduced losses. The infrastructure also includes a 750 kV AC power line, which serves as a critical component in aggregating power from individual wind turbines before it enters the main HVDC corridor. These transmission solutions were essential in allowing the full utilization of the farm's generation capacity, moving the project beyond the earlier 1.5 GW bottleneck.
Coordinated Control Systems
Beyond physical infrastructure, operational efficiency was improved through software and control systems. In 2012, a 'wind power coordinated control system' was implemented to manage the fluctuating output of the turbines. This system helps stabilize the daily production, which has been noted to reach levels such as 1 GWh in specific operational contexts. By coordinating the output of multiple turbines, the system reduces the volatility of power fed into the grid, making it more predictable for grid operators. These technical solutions, combined with the expansion of total generation capacity to 10 GW after years of delays, have been critical in mitigating curtailment and maximizing the economic viability of the Gansu Wind Farm.
What are the main challenges of the Gansu Wind Farm?
The Gansu Wind Farm Project has faced significant operational and economic hurdles, primarily stemming from its remote desert location in western Gansu province. Despite an abundance of wind resources, the complex suffered from severe underutilization in its early years. In 2015, the facility was operating at below 40% utilization of its then-current 8 GW capacity. This low output was not due to a lack of wind, but rather a mismatch between generation and demand, exacerbated by inadequate transmission infrastructure and local market dynamics.
Transmission and Grid Infrastructure
The primary bottleneck was the distance between the wind farms near Jiuquan, Guazhou County, and Yumen City, and the major consumption centers. The lack of robust high-voltage direct current (HVDC) lines meant that much of the generated power was either lost or curtailed. This infrastructure deficit was partially resolved in 2017 when the 2,383 km long Jiuquan - Hunan HVDC transmission line entered service. This critical link connected the remote Gansu complex directly to the Hunan regional grid, significantly enhancing the ability to export power and allowing for fuller utilization of the generation capacity.
Economic Factors and Local Competition
Beyond infrastructure, economic competition with local energy sources played a crucial role in the farm's utilization rates. Local favoritism toward traditional coal power created a competitive disadvantage for wind energy. The economic comparison highlighted this disparity: wind power prices were recorded at 0.54 yuan, compared to just 0.3 yuan for coal power. This price gap made coal a more attractive option for local consumers and grid operators, further contributing to the underutilization of wind resources before the expansion of transmission networks and the completion of later construction phases.
Geography and location
The Gansu Wind Farm Project, also known as the Jiuquan Wind Power Base, is situated in the western region of Gansu province in China. The facility occupies vast desert areas, specifically within the Gobi Desert landscape. The wind farms are distributed across two localities in Guazhou County and extend to areas near Yumen City. This northwestern province is characterized by an abundance of wind resources, making it a strategic location for large-scale wind energy generation. The remote setting places the complex far from major population centers and industrial hubs, necessitating significant infrastructure development to harness the energy effectively.
Wind Resources and Physical Setting
The physical environment of the Jiuquan Wind Power Base is defined by its arid, desert terrain. The area near Jiuquan, Guazhou County, and Yumen City provides extensive flat land suitable for the deployment of numerous wind turbines. The region's wind abundance is a key factor in the project's viability, allowing for high energy yield despite the harsh climatic conditions. The desert setting presents unique challenges for construction and maintenance, including sand accumulation on turbine blades and extreme temperature variations. The project's location in the northwest of Gansu province leverages the natural wind patterns of the Gobi Desert, which are consistent and strong enough to support a multi-gigawatt capacity installation.
Logistical Challenges and Grid Connection
The remote location of the Gansu Wind Farm relative to major Chinese cities poses significant logistical challenges. The distance from key load centers and port cities requires extensive transmission infrastructure to deliver the generated power to consumers. In 2017, the 2,383 km long Jiuquan - Hunan HVDC transmission line entered service, connecting the remote complex to the Hunan regional grid. This transmission line was crucial for allowing full utilization of the generation capacity, mitigating the issue of curtailment that had previously affected the project. Prior to this connection, the complex operated at below 40% utilization of its capacity, highlighting the importance of grid integration in remote wind farm projects. The completion of the latest phase of construction, after four years of delays, brought the total generation capacity to 10 GW, further emphasizing the scale of logistical and engineering efforts required to sustain such a large installation in a desert environment.

This massive capital outlay reflected the scale of the infrastructure required to develop the desert areas near Jiuquan, Guazhou County, and Yumen City. The project's financial structure underscored the commitment to transforming the region's energy profile, despite the initial challenges in integrating such a large capacity into the existing grid infrastructure.
Grid Integration and Utilization Challenges
Despite the significant investment, the project faced severe underutilization in its early years. In 2015, the complex was operating at below 40% utilization of its current 8 GW capacity, with a planned capacity of 20 GW. This low utilization rate highlighted the critical importance of transmission infrastructure in realizing the economic potential of the wind farm. The remote location of the complex in western Gansu province meant that without adequate grid connections, much of the generated power remained stranded.
The situation improved significantly with the completion of the Jiuquan - Hunan HVDC transmission line. In 2017, this 2,383 km long transmission line entered service, connecting the remote complex to the Hunan regional grid. This infrastructure development allowed for the full utilization of the generation capacity, effectively bridging the gap between the wind-rich northwest and the energy-hungry central regions. The transmission line's completion was a pivotal moment in the project's economic viability, demonstrating the critical role of grid infrastructure in supporting large-scale renewable energy projects.
