On the afternoon of December 28, the first flight of energy-saving Dunhuang 100MW tower solar thermal demonstration power station, China's first 100MW solar thermal power station, was successfully held in Dunhuang.

Member of the Standing Committee of the Jiuquan Municipal Party Committee, Secretary of the Dunhuang Municipal Party Committee Zhan Shunzhou, Member of the Standing Committee of the Jiuquan Municipal Party Committee, Executive Deputy Mayor Li Yongjun, National Energy Administration Energy Regulatory Expert, Professional Vice President and Secretary-General of the All-Union New Energy Chamber of Commerce Zeng Shaojun, Vice President of Electric Power Planning and Design Institute Sun Rui, former Director of the Research Office of the National People's Congress Environment and Resources and Resources Protection Committee Xu Xiaodong, Special Researcher Xu Xiaodong, and jointly participated in lighting the energy column symbolizing the first voyage of energy-saving Dunhuang 100MW tower-type photothermal demonstration power station. Dunhuang municipal party committee deputy secretary, municipal government mayor Jia Taibin presided over the conference. The commissioning ceremony was witnessed by more than 400 people including on-site government leaders, industry experts, and media, and was a complete success!

Welcome Speech by Liu Qiang, Commander-in-Chief of the Photothermal Project of Dunhuang's First Sail

In the construction process of the first voyage energy-saving Dunhuang 100MW tower solar thermal power generation project, we have gained experience and growth, effectively improved the efficiency of organization and management, and reduced the construction cost. From the test and debugging of the project monomer to the various parameters obtained now, the performance of the heliostat, heat absorber, control system, air cooling system and other equipment or systems of Dunhuang Phase II project has made great progress compared with Phase I, the price of some of the equipment has dropped significantly; behind this is the improvement of competitiveness brought about by the superposition of design optimization capabilities, intelligent manufacturing, and scale effects. After the practice of Dunhuang Phase I and Phase II projects, we believe that the molten salt tower technology route is feasible, and there is still a lot of room for decline in management costs and manufacturing costs, which will be able to bring further reduction in unit power generation costs.

 

Zhan Shunzhou, member of the Standing Committee of Jiuquan Municipal Party Committee and Secretary of Dunhuang Municipal Party Committee, delivered a speech

Dunhuang is not only the location of the first batch of photothermal demonstration projects, but also after nearly ten years of hard work, Dunhuang has successfully established itself as the first domestic solar power demonstration base above one million kilowatts, the first batch of national new energy demonstration cities, and successfully included in the national high proportion The establishment of new energy demonstration cities and the third batch of national low-carbon city pilot lists. The successful completion and grid-connected operation of the first energy-saving Dunhuang 100MW molten salt tower solar thermal power generation project marks a new stage for China's solar thermal power generation industry, and will also inject stronger power into the Dunhuang new energy industry.

Jiuquan Municipal Standing Committee, Executive Vice Mayor Li Yongjun speech

For a long time, Jiuquan City has vigorously promoted the large-scale development of wind power, photovoltaic and photothermal, aiming to promote the adjustment of Jiuquan's energy structure and help the construction of ecological civilization. As an important way of clean energy power generation, photothermal power generation has broad prospects for development. Eight of the first batch of photothermal power generation demonstration projects landed in Jiuquan, which is the region with the most complete technical route. At present, Shouhang Energy Saving has made remarkable achievements in the field of photothermal power generation, and will play a positive exemplary role in the development of Jiuquan's new energy industry in the future.

National Energy Administration energy regulatory expert Zeng Shaojun speech

Photothermal power generation is not only a new kind of power supply, especially for the existing new energy, it is a stable power supply with peak and voltage regulation. In the future, it will replace the traditional thermal power and become an important power generation form to improve the energy structure of our country.

Speech by Sun Rui, Vice President of General Electric Power Planning and Design Institute

Photothermal power generation integrates power generation and energy storage, and can be adjusted according to the needs of the power system. Compared with wind power and photovoltaic, it has the characteristics of stable, continuous and controllable. According to my country's energy development strategy, non-fossil energy will gradually replace fossil energy, and photothermal power generation will become an important way to promote my country's energy transformation. Through the construction of photothermal demonstration projects, the technical level of photothermal power generation will be improved, and domestic enterprises will accumulate more practical experience, better participate in project construction at home and abroad, and make positive contributions to energy transformation.

Speech by Xu Xiaodong, Special Researcher of the Counselor's Office of the State Council

The grid-connected operation of the first energy-saving Dunhuang 100MW tower-type photothermal demonstration power station is an important milestone in my country's photothermal power generation industry and an important node in my country's clean energy development. With its stable power output advantages, photothermal power generation will become an energy structure An indispensable member in adjustment.

General Manager Gao Feng Releases Investment Results

The first energy-saving Dunhuang 100MW molten salt tower solar thermal power generation demonstration project was officially connected to the grid on December 28, 2018. The project covers an area of 800 hectares. It is a 100MW molten salt tower solar thermal power station with the largest single condensing scale, the highest heat absorption tower, the shortest construction period and 24-hour continuous power generation in the world. Peugeot makes China one of the few countries in the world that master the 100MW molten salt tower solar thermal power generation technology. The project lens field consists of more than 12000 heliostats around a 260-meter-high heat absorption tower, each with a lighting area of 115 square meters. The project is equipped with an 11-hour molten salt heat storage system, which can achieve 24-hour continuous power generation, and the annual power generation can reach 0.39 billion kilowatt-hours. The environmental benefits brought by the annual emission reduction and consumption of excess production energy of the project are equivalent to 10000 mu of afforestation!
