The operation and maintenance cost of wind farm is 0.6 yuan per watt. Generally, the cost of wind power is calculated per watt. 1gw of wind power is equal to 1000 megawatts, one megawatt is equal to 1 million watts, and 1gw of wind power is 1 billion watts. Generally, the investment and construction cost of one watt of wind power is about 5.5 yuan. The cost of 1gw of wind power is About 5.5 billion yuan.
The price of wind power is indeed higher, it is about 1 times more expensive than thermal power. However, judging from the trend, the cost of wind power generation is on a downward trend, and has now dropped to 0.5~0.6 yuan per kilowatt/hour, which is the entire cost of wind power. As technology advances, costs will fall further. Compared with thermal power generation, one of the biggest advantages of wind power is its environmental benefits. At present, the incomplete cost of thermal power generation has reached 0.2~0.3 yuan per kilowatt/hour, which does not include the treatment cost of discharged pollutants. Moreover, thermal power generation is also affected by the fluctuation of fossil energy prices.
