On June 22, the reporter learned from the State Grid Hangzhou Power Supply Company that by 2030, Hangzhou will build five water pumping storage projects, with a total of 7.4 million kV safety, and the total investment is expected to exceed 40 billion yuan. These projects will contribute to the realization of carbon peaks, carbon neutralization and contribution, and fill the gap in Hangzhou pumping storage projects.

Among them, the two major projects of Jiande Wulong Mountain and Tonglu Baiyunyuan are expected to start construction by the end of 2022. At present, the construction of the Ulongshan project with a capacity of 2.4 million kilowatts has been registered with the provincial development and reform commission, and it will become the largest pump storage project in East China. The project command of Tonglu Baiyunyuan, with a capacity of 1.4 million kilowatts, has officially unveiled, and both have become the largest investment projects in local history.

At that time, the Fuchun River Water will cross the mountains and mountains, fly down, and impact the power generation flywheel, which will transport a steady stream of green energy for Hangzhou Power Grid. It is expected that the average annual power generation of the two pumping storage power stations will reach 4.32 billion kWh, reducing 3.7 million tons of carbon emissions.

In addition, Hangzhou has vigorously promoted the other three large -scale pumping projects in Lin'an, Chun'an Qiandao Lake, and Fuyang Changan, respectively. Five pumping storage projects are accelerating, and they are expected to be put into operation by 2030. After completion of the construction, under the calculation of the current pumping storage price, annual power generation income can reach 7.5 billion yuan, and it will further drive investment, tourism, and employment in mountainous areas. Build a comprehensive promotion of common prosperity.

It is understood that a pumping power station is like a large "charging treasure". When using the electric low valley, use electricity to pump water into a reservoir with high altitude. During the peak of electricity, water and power generation, transform the potential energy of water into electrical energy, and then complete the task of griding peak -regulating valley and current frequency adjustment. It is one. The high -quality fast and flexible adjustment of the power supply is also a large energy storage facility that is currently mature, reliable, and large -scale development. It is also an important part of the new power system. According to estimates, a typical pumps of 1.2 million kilowatts of water storage power stations can be stored in about 120,000 electric vehicles.

Hangzhou Power Grid is a typical receiving grid, facing two uncertain factors: "large -scale external electricity" and "high -proportion new energy". At present, the proportion of external electricity is more than 80%. In the future, as ± 800 kV Baihetan special high -voltage projects are put into production with local distributed new energy, the "uncertainty" features of power supply will be more prominent. At the same time, due to the industrial structure, Hangzhou Power Load Peak Valley has continued to increase. In 2021, the city's largest day -to -peak and valley difference reached 7.35 million kilowatts, and the demand for peak adjustment of power grids was increasing. To this end, the flexible and adjustable energy storage resources -pumping storage power stations have become the same choice for Hangzhou Power Grid Peak Mixing Valley, frequency adjustment, and emergency reserve.

Liu Aixin, Director of the Energy Division of the Hangzhou Development and Reform Commission, introduced that the special class has been established to coordinate the preliminary work. In order to ensure that these pumping storage projects were successfully accessible to Hangzhou Power Grid, the State Grid Hangzhou Power Supply Company co -ordinated regional power grid resources, fully considered the distribution and access needs of the power storage station, and rationally planned the construction of the power grid, accelerated the 500 kV Jiande changes Construction of related supporting grid engineering.

"The pumping storage project can not only vigorously improve the ability of Hangzhou power grid to cut peak -cutting, but also radiate the East China Power Grid and support the peak adjustment needs of Shanghai and Jiangsu Power Grid." Said Shang Jiayi, deputy director of the Development and Construction Department of State Grid Hangzhou Power Supply Company. At the same time, they will also drive the construction of surrounding mountain roads, residents' employment, tourism resources, and urbanization construction, making water conservancy projects a "cornucopia" for Fu Min and strong villages.
