For the subsidy policy on production equipment, you can check the "Interim Measures for the Management of Special Funds for the Industrialization of Wind Power Equipment". Those who meet the specified conditions will be subsidized at the standard of 500 yuan/KW. Machine manufacturing enterprises and key parts manufacturers Each gets 50%.
The on-grid electricity price per kilowatt hour of electricity varies from place to place. The specific price can be checked. It is related to the area where the construction is invested, the agreement with the power grid when bidding for the wind farm, and the ability of the wind power plant operator. But they are much higher than coal-fired ones. The government withdraws 1%/kWh (civilian and fertilizer) and 2%/kWh (industrial) from other electricity charges on the Internet to subsidize wind power.
The subsidized electricity price ranges from 0.15 to 0.28 yuan/kWh, and the national average is roughly 0.24 yuan/kWh.
I need to give points, I have written so much
For wind power generation, the concept of how many levels of wind power is used is too rough. Due to different generator capacities, the requirements for wind speed are also somewhat different. However, generally if the wind speed exceeds 3m/s, the wind turbine can generate electricity. However, wind power generation does not depend on how high the local wind speed can reach, but on how long the local wind farm that generates electricity for this wind turbine can operate per year. Based on the current wind power subsidy price set by the state, if the power generation time is less than 2,000 hours that year, there will be no profit.
