Standing on the new track of green and low-carbon development, the coastal areas of Jiangsu have continuously promoted the construction of major energy projects to deliver green energy for local economic and social development by adhering to the goal of "carbon peaking and carbon neutrality" as the guide.
At the construction site of the booster station of CNNC Tianwan 2 million kilowatt mudflat photovoltaic demonstration project, more than 160 workers performed their duties by stepping up construction.
As a major energy construction project in the province, CNNC Tianwan 2 million kilowatt mudflat photovoltaic demonstration project will build a total installed capacity of 2 million kilowatts by using the 28300-mu warm water sea area of Tianwan Nuclear Power Base, and adopting the scheme of block power generation and centralized grid connection.
At present, the booster station project has completed the individual civil engineering of eight buildings, and work on electrical installation has got off to a smooth start so as to pave the way for the scheduled operation before the Spring Festival.The project will transmit an average of 2.234 billion kilowatt hours of online electricity annually by saving 6812 million tons of standard coal, reducing greenhouse gas emissions by 1.7711 million tons, and reducing sulfur dioxide emissions by 15000 tons.
“The operation of photovoltaic power station projects connected to the Jiangsu power system will play a certain role in optimizing the power supply structure of the power grid and improving the reliability of power supply”, Zhao Weiran, a worker of Booster Station of CNNC Tianwan 2000000kW Mudflat Photovoltaic Demonstration Project, said.
Rows of container-like white energy storage tanks are very eye-catching at the site of the Jiangsu Fengchu Shared Energy Storage Project located in Yangkou Town, Rudong County.
The energy storage equipment of this project adopts a prefabricated compartment layout. By utilizing the characteristics of electrochemical energy storage, they can participate in peak shaving operation of the power grid, assist in peak shaving and valley filling, and increase energy efficiency.
“Compared to traditional gravity energy storage, the utilization efficiency of pumped storage power stations can reach 90%, and their reaction speed is also faster. They can release electricity into the grid in the first time, quickly meeting the electricity needs of users”, Liang Xiao, Professional Supervision Engineer of Nantong Electric Power Design Institute Co., Ltd. Supervision Branch, said.
The shared energy storage project has a total investment of 1 billion yuan and is the first shared energy storage station in East China and the largest electrochemical energy storage station in Jiangsu Province. With grid connection, the annual online discharge capacity will reach 120 million kilowatt hours, which can achieve two charges and two discharges per day, with a single discharge capacity of approximately 360000 kilowatt hours. At present, the project construction has been basically completed with comprehensive grid connection scheduled for the end of October.
