China Green Development Investment Group (CGDG) dedicates to promoting the development of the green energy industry.
To ramp up the high-quality development of the new energy industry, CGDG has been striving for large-scale and demonstration green energy projects. It carried out technological innovation, and developed original technologies, making contributions to the construction of a clean, low-carbon, safe and efficient energy system.
In Tongyu County, Baicheng City, Northeast China’s Jilin Province, the Tongyu Phase II 100,000-kilowatt wind power project constructed by the company completed trial operation in December last year and was officially connected to the grid for power generation.
The wind farm, despite the strong winds and frost, completed construction within 155 days, finishing project approval, construction, completion, and operation within the same year.
According to estimates, the wind farm can provide 299 million kWh of clean electricity every year, save 36,800 metric tons of standard coal, and reduce carbon dioxide emissions by 298,400 metric tons.

"Relying on China’s national new energy development plan, CGDG has developed and constructed offshore wind power, onshore wind power, photovoltaic power and solar thermal power projects in 12 provincial-level regions including Inner Mongolia, Gansu, Qinghai, and so on, " said a spokesperson of the company.
"The company has formed a green energy industrial pattern featuring sea and land development, multi-energy complementarity, and technology empowerment."
Another large-scale multi-energy complementary project of the CGDG is under construction in the photovoltaic solar park in Wutumeiren Township, Golmud City, Qinghai Province. The project, with a total installed capacity of 3.3 million kilowatts, is scheduled to complete construction by the end of China’s 14th Five-Year Plan (2021–25).
The project is in response to the new requirements of the integrated development of new energy. It aims to support stable operation of power grids, optimize power output characteristics, and strengthen system adjustment capability.
Featuring photovoltaic sand control, ecological restoration, green development, industry promotion, rural revitalization, and technology demonstration, it helps with regional coordinated development.
"Although the natural environment is harsh, we will go all out to speed up the construction, and strive to put the project into operation and bring benefits as soon as possible, in a bid to deliver the high-quality development of Qinghai's clean energy industry," a spokesman for the project said.
In the Golmud East Export Solar PV Park, a demonstration project of liquid air energy storage built by CGDG and the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences runs smoothly.
Liquid air energy storage technology is a new method to achieve deep consumption of new energy such as wind and solar energy and grid connection, rationally absorb low-peak power and different forms of waste heat resources in the grid, and output with stability various forms of energy such as cold, heat, electricity and industrial gas when needed.
The new energy storage method has the outstanding advantages of large-scale long-term energy storage, clean and low-carbon features, safety, and without restriction by geographical conditions. It has a wide range of application scenarios.
The liquid air energy storage demonstration project has an installed capacity of 60,000 kW/600,000 kWh and is equipped with a 250,000 kW photovoltaic project.
Aiming to declare the first major technical equipment across the country, the project breaks through the equipment constraints of liquid air energy storage system from 100 kW to 10,000 kW levels. It also has promoted the improvement of the major technical equipment in the energy field.
After the project is completed and put into operation, it will contribute more innovative practices to extend the multi-energy complementary industrial chain, improve the structure of the energy field, ensure energy security, and promote ecological progress.
In addition, CGDG has been researching and expanding new business forms and models in terms of comprehensive energy services, striving to promote the extension and expansion of the industrial chain and the advancement of the value chain, so as to build a comprehensive green energy service industry cluster.
