Beijing 2022 Winter Olympic Games are in full swing. According to official news, all 26 venues in the three competition areas of this winter Olympic Games use "green power", which is the first time in the history of the Olympic Games to realize 100% green power supply for all venues.
Where does "green electricity" come from? Foreign Ministry spokesman Zhao Lijian used "Zhang Bei's wind lights up Beijing's lights" to explain the green Olympic concept of this winter Olympics to the outside world. Behind this, in fact, a number of energy enterprises have established renewable energy demonstration projects in Zhangbei, Hebei, transforming the wind in Zhangbei into clean electricity, which is incorporated into the northern Hebei Power Grid and then transmitted to the three competition areas of Beijing, Yanqing and Zhangjiakou.
several energy enterprises help
According to the reporter of Securities Daily, the "green power" supply of Beijing 2022 Winter Olympic Games includes photovoltaic, wind power, hydropower and other clean energy. Many central power enterprises such as state grid, China Huaneng, state power investment, Datang Group, national energy group, Three Gorges group, China Energy Engineering Corporation Limited(601868) , Power Construction Corporation Of China Ltd(Powerchina Ltd)(601669) and power enterprises such as Beijing energy group participated in the relevant work.
The reporter of Securities Daily learned from Power Construction Corporation Of China Ltd(Powerchina Ltd)(601669) that the Batou wind farm, panchanghe wind farm, Shuiquan wind farm, beizhuangbao photovoltaic power station and other major projects invested and operated by its new energy group are responsible for ensuring the power supply of this winter Olympic Games. The total installed capacity of the four electric fields (stations) is 400 MW, the annual feasibility study on grid power is about 960 million kwh, about 300000 tons of standard coal can be saved and 790000 tons of carbon dioxide can be reduced every year.
In addition, the Fengning pumped storage power station designed and constructed by Power Construction Corporation Of China Ltd(Powerchina Ltd)(601669) will sit firmly in the rear and play the role of "voltage regulator" and "super charging treasure" to ensure the stable operation of Zhangbei flexible direct power grid and the full green power coverage of Winter Olympic venues.
According to reports, as a national key project, the operation of Fengning pumped storage power station can convert the power output from unstable photovoltaic, wind power and other clean energy in Beijing, Tianjin and Hebei into stable green power. It can absorb 8.8 billion kwh of excess power every year, and the annual power generation reaches 6.612 billion kwh, which can meet the power consumption of 2.6 million households in a year and reduce carbon emissions by 1.2 million tons.
During the day, Fengning pumped storage power station can start pumping with excess electricity and convert electric energy into "potential energy" for storage. In the evening, Fengning pumped storage power station releases water for power generation to convert the "potential energy" into electric energy to ensure the power consumption of the Winter Olympic Games.
According to the introduction of China Energy Engineering Corporation Limited(601868) , China Energy Engineering Corporation Limited(601868) Gezhouba No. 2 company has also undertaken key construction tasks such as upper and lower reservoirs, inlet and outlet, gate shaft, hoist building and barrage of Fengning pumped storage power station. The project department has promoted the safe and high-quality construction of the power station by innovating advanced technical means such as digital dam, rapid detection of rolling quality, intelligent digital grouting and one-time sliding surface forming, which has laid a solid foundation for realizing the goal of putting into operation and power generation on schedule.
As the signing partner of green power supply for the venues of Beijing 2022 Winter Olympic Games and winter Paralympic Games, Beijing Energy Group makes use of the green energy base arranged and constructed in Beijing, Tianjin and Hebei to contribute to the 100% green operation of this winter Olympic Games.
On the night of the opening ceremony on February 4, more than 100 employees of green power bases such as Jingzhang Olympic wind power project, Guanting wind power project, Huainan wind power project and Yanqing photovoltaic project of Beijing Branch of clean energy group stuck to the front line to overcome difficulties such as cold wind and low temperature Each electric facility shall be inspected for many times and equipment testing shall be carried out continuously to ensure the reliable power supply of the wind farm.
In addition, the jingnengkang wind power project jointly contracted by Power Construction Corporation Of China Ltd(Powerchina Ltd)(601669) Shanghai Power Construction and Shanghai Electric Power Co.Ltd(600021) Design Institute and participated by the fourth Hydropower Bureau is also one of the important sources of green power supply for Beijing 2022 Winter Olympic Games, which also undertakes the important task of clean heating in the capital. The Yanqing competition area comprehensive energy project undertaken and operated by Beijing Energy Group clean energy Beijing Branch has realized 100% renewable energy heating in the Winter Olympic Village, which is the first time in the history of the Olympic Games.
popularize the concept of green development
" China Three Gorges Renewables (Group) Co.Ltd(600905) mainly provides clean energy for the Winter Olympic venues and supporting facilities through power trading. The company participated in the green power trading of Beijing Winter Olympic venues twice, with a total power of 51 million kwh, of which 21 million kwh were provided during the competition to fully contribute to the green winter Olympic Games." China Three Gorges Renewables (Group) Co.Ltd(600905) told the reporter of Securities Daily that the green power it provides mainly comes from the wind power projects in Zhangjiakou, and the generated power is sent to the Winter Olympic venues through the Zhangbei flexible DC demonstration project. In addition, China Three Gorges Renewables (Group) Co.Ltd(600905) donated 200000 tons of CER carbon emission reduction to the Winter Olympic Games.
China Three Gorges Renewables (Group) Co.Ltd(600905) told the reporter of Securities Daily that 100% of the current Winter Olympic Games will use green power, which will further drive the whole society to establish the concept of green development and stimulate green consumption. China Three Gorges Renewables (Group) Co.Ltd(600905) as a pure new energy power generation enterprise, it will make full use of the east wind of the Winter Olympics to further promote the supply of green power and carbon assets, provide a steady stream of green products to the society, and contribute to the realization of the "double carbon" goal and the construction of a new power system with new energy as the main body.
How difficult is it to realize 100% green power supply for the venues in the three competition areas of this winter Olympic Games? Liu Xiaoyan, an analyst of Longzhong information energy industry, told the Securities Daily that due to the inherent randomness and volatility of new energy, large-scale new energy grid connection is a worldwide problem. Zhangjiakou is an important new energy base in China, and the Zhangjiakou beirouzhi project adopts China's original and world-leading flexible DC power grid new technology, which can effectively suppress the AC voltage fluctuation, reduce the impact of power fluctuation on the receiving power grid, and effectively solve the three major problems of "not going up", "not delivering" and "difficult to absorb" in the grid connection safety of intermittent energy power generation such as wind power and photovoltaic, The large-scale and unstable renewable energy in Zhangjiakou will be collected at multiple points to form a stable and controllable power supply to deliver green power to Beijing.
Liu Xiaoyan said that the realization of 100% green power supply in the venues of the Winter Olympic Games is in line with the concept of "sustainable development" of the Winter Olympic Games, which demonstrates China's confidence and attitude in vigorously developing the clean energy industry. At the same time, it is also an important way to explore the integration of large-scale "transmission, grid connection and consumption" of clean energy, which will play a great role in three fields: wind power and photovoltaic will enter the doubling stage; Energy storage will achieve explosive growth; Energy digitization ushers in a golden period of development.
