Stick to your post and pay silently.

A number of key projects have been connected to the grid, connected and poured.

They bid farewell to the old and welcome the new in a unique way for engineers.

Zhala Hydropower Station successfully realized diversion and closure.

　　Recently, the diversion tunnel project of Zhala Hydropower Station in Yuquan River, Xizang, China’s Datang, which was built by Chengdu Branch of the Third National Security Bureau, ushered in an important node-the diversion tunnel project officially overflowed, laying a solid foundation for the interception task of Zhala Hydropower Station.

　　Zhala Hydropower Station is located in Zhalang Village, Bitu Township, Zuogong County, Changdu City, Xizang Autonomous Region, with a total installed capacity of 1.015 million kilowatts. The construction of this project will play an important leading and demonstrating role in realizing the complete localization of intellectual property rights in the whole industrial chain of impulse turbines and the independent control of key core technologies of hydropower equipment.(Contributed by: Zhang Yonghu Wang Hongjiang)

The whole county roof distributed photovoltaic project in Guiping realizes full capacity grid-connected power generation.

　　On December 30, 2023, the distributed photovoltaic (Phase I) power generation project in Guiping County, Guangxi Province, which was built by Nanning Branch of the First National Security Bureau, realized full-capacity grid-connected power generation. The completion of this important node lays a good foundation for the next step of power generation, and is of great significance to promoting the development of green energy, improving ecology and promoting rural revitalization in Guigang City.

　　The distributed photovoltaic project in the whole county of Guiping is mainly based on 27 local campuses in Guiping City, with a total construction scale of 4.65 MW, a total investment of about 17.3 million yuan, and an average annual power generation of about 4.81 million kWh. It is connected to the grid-connected rooftop distributed photovoltaic project with a voltage level of 380 volts. The project adopts the mode of "spontaneous self-use and surplus electricity connected to the grid" to generate electricity, which can save about 173 tons of standard coal every year and reduce the emission of 480 tons of carbon dioxide, effectively realizing the green, low-carbon, energy-saving and renewable utilization of energy.(Contributed by: Jiang Jianming)

The first batch of power generation units of Yuxi Yimendini photovoltaic project were successfully connected to the grid.

　　On December 31, 2023, the first batch of power generation units of Yunnan Yuxi Yimendini photovoltaic power generation project, which was built by Yunnan Company of the First National Security Bureau, were successfully connected to the grid, injecting new vitality into the local green energy field.

　　The project is located in Tongchang Township, Yimen County, Yuxi City, Yunnan Province, with a total area of 696.45 mu and an installed capacity of 25 MW. The construction contents of the project include photovoltaic field, switching station, collecting line and sending line, etc.(Contributed by: Li Wei)

The ventilation and safety tunnel of Ningguo Pumped Storage Power Station was excavated to the powerhouse in advance.

　　On December 30, 2023, the ventilation and safety tunnel of Anhui Ningguo Pumped Storage Power Station, which was built by Nanchang Branch of the Second National Security Bureau, was successfully excavated to the factory building, and the node goal was completed five months ahead of schedule.

　　The ventilation and safety tunnel has a total length of 885 meters, and the excavation section is 7.2 meters *7 meters. The full-face blasting method is adopted for excavation.Ventilation and safety tunnel is the key work of the whole power station construction, which determines the construction period of the power station and lays a solid foundation for the underground powerhouse construction of the power station to be delivered to the working face in advance.(Contributed by Zhou Zhaoxiang)

The pilot tunnel on the first floor of the main (auxiliary) powerhouse of Songyang Pumped Storage Power Station was successfully connected ahead of schedule.

　　On December 30, 2023, the pilot tunnel on the first floor of the main (auxiliary) powerhouse of Zhejiang Songyang Pumped Storage Power Station project, which was built by Changzhou Branch of the Second National Security Bureau, was successfully completed ahead of schedule, which marked the important construction progress of the project and created favorable construction conditions for the expansion and excavation of the upstream and downstream side walls of the main (auxiliary) powerhouse.

　　The underground powerhouse is composed of a main engine section, an auxiliary engine section and an installation room, which are arranged in a "I" shape, and the installation field and the auxiliary engine section are arranged at the left and right ends of the main engine section respectively. The total excavation size is 185.2m * 25m * 56.8m (length * width * height), and the elevation is 313.5-370.3m. The stonework cave is excavated in 7 layers, with the maximum excavation height of 10.6m..(Contributed by Li Jiaan)

The foundation of the first turbine of Huludao Wind Power Project was successfully poured.

　　On December 30, 2023, the foundation of No.45 wind turbine in Bid A of Lianshan 250 MW wind power project in Huludao, Datang, Liaoning Province, which was built by Xiamen Branch of the Second National Security Bureau, successfully completed concrete pouring, which sounded the clarion call for comprehensive engineering construction.

　　The project is located in Lianshan District, Huludao City, Liaoning Province. The total installed capacity of the project is 110 MW, and 22 5.0 MW wind turbines are installed. The tower is designed as a steel tower with a hub height of 120 meters and an impeller diameter of 193 meters. After the completion of the project, it will provide a cleaner and more reliable power supply for Huludao City and its surrounding areas, effectively promote energy conservation and emission reduction, protect the ecological environment to adapt to sustainable development, promote the high-quality development of regional economy, and achieve a double harvest of environmental and economic benefits.(Liu Yisheng)
