2. The first batch of units of my country's first flexible DC offshore wind power project were officially connected to the grid for power generation

On November 8, the first unit of the Three Gorges Group Jiangsu Rudong Offshore Wind Power Project (referred to as the Three Gorges Rudong Project) officially sent power to the Jiangsu Power Grid, marking the successful connection of the first batch of units of my country’s first flexible DC offshore wind power project to the grid.

The Rudong Three Gorges Project is located in the Huangshayang waters of Rudong County, Jiangsu Province. It is the first offshore wind power project in Asia that uses flexible DC transmission technology. The generated energy is transmitted to the grid through a flexible DC transmission project (referred to as Rudong Flexible Direct Project). The project is mainly composed of two sea booster stations, an offshore converter station, a DC submarine cable, and an onshore converter station.

The Rudong Three Gorges project will be put into operation in December this year. By then, the annual on-grid power will reach 2.4 billion kWh, which can meet the annual power consumption of about 1 million households. Compared with coal-fired power plants of the same scale, it can save standards every year. Burning approximately 740,000 tons of coal and reducing carbon dioxide emissions of approximately 1.83 million tons will add kinetic energy to optimize the local energy structure and ensure power supply this winter and next spring, effectively helping to achieve the goal of "carbon peak and carbon neutrality".

5. The steel pipe pile sinking construction of Shantou's first offshore wind power project was completed

On November 10, the last single pile of Datang Nan'ao Lemen I Offshore Wind Farm Project Bid Section 2 contracted by the New Energy Branch of China Railway Construction Port and Shipping Administration was successfully completed, marking the completion of the steel pipe pile of the wind farm. The pile sinking tasks are all completed.

Datang Nan'ao Lemen I Offshore Wind Farm Project Tender Section 2 construction tasks mainly include 18-station wind turbine foundation construction, tower tube manufacturing, wind turbine installation, and the actual construction of 19 single piles through the coordination of the owner. Among them, the largest single pile of the wind farm weighs about 1,570 tons, and the pile length is about 101 meters. Since the start of the construction of steel pipe piles, the project department has overcome various unfavorable factors. It took 72 days to complete the construction of all 19 steel pipe piles.

It is reported that the total installed capacity of Datang Nanao Lemen I offshore wind farm is 245 MW. After the construction is completed, the annual power generation is expected to be 751 million kWh and the output value is 565 million yuan. It can save 240,000 tons of standard coal and reduce carbon dioxide emissions 45 10,000 tons, will effectively promote the large-scale development of offshore wind power generation in Shantou.
