New wind power records.
The Fujian Pingtan Offshore Wind Farm was fully connected to the grid last month. The project consists of 11 units with a capacity of more than 8 MW, including the world's largest single turbine with a capacity of 16 MW. The project, with a total installed capacity of 111 MW, is the largest offshore wind farm of its kind in the world. Once the project is in full operation, the average annual electricity generation will reach 3.645 billion kWh, which will emit nearly 300,000 tons of CO2 per year.
Back in the spring, Three Gorges Energy, China's state-owned energy company (ctg.com.cn), launched the world's most huge offshore wind turbine. So far, it is the largest ever connected to the power grid. It has a capacity of 16 MW and a diameter of 260 meters. Already on September 1, the turbine set a new record for daily power generation per unit of capacity. At a maximum wind speed of 23.56 m/s, 384,100 kWh were generated. The turbine's 24/7 operation at full capacity provides enough energy to supply nearly 170,000 households daily.
In comparison, conventional wind turbines are 50-60 meters in diameter and produce no more than 3 MW.
Each blade of the structure reaches a length of 123 meters and weighs almost 54 tons. For a more accurate understanding, the height of the wind turbine from base to peak, is comparable to the height of a fifty-story building, i.e. about 152 meters.
The total weight of the tower reaches 385 tons. On top of that, there are also three 123-meter-long blades of 54 tons each. The turbine itself can withstand wind gusts of up to 287 km/h. Up to 34.2 kWh of energy is transferred to the Chinese grid every time the turbine makes a full turn. It is estimated that such a plant should produce about 66 GWh annually.
The wind turbine is located in the Taiwan Strait, which regularly experiences Level 7 "storm" conditions, with wind speeds exceeding 51 km/h almost 200 days a year.
Noteworthy, GE Renewable Energy's 14 MW wind turbine in Rotterdam was previously considered the largest. However, now there is no other wind turbine equal to China's, and there will certainly be none in the near future.
Speaking about Russia, Kochubeyevskaya Wind Farm is our largest and most powerful wind farm. It consists of eighty-four installations, each of which accumulates 2.5 MW. The average annual output of the plant reaches almost 500 million kWh. This volume is enough to provide stable power supply, for example, to a city like Stavropol.
