It depends on the size of the wind farm you want to build and where it will be built. The wind turbine itself has a certain cost, but the difference in site can affect the overall cost of a wind turbine. On land, the cost of a wind turbine is generally around 6 to 10 million (for a power of around 1 MW). The cost of offshore wind farms can be even higher.
How much does it cost? invest in a small renewable energy power plant?
The investment amount, power generation and economic benefits of offshore wind power projects will be affected by many factors, such as location water depth, wind speed, equipment selection, construction period, policy subsidies, etc. Therefore, it is impossible to give a precise answer. The following provides only an approximate reference:
1. Investment amount: monSo much of the investment for 1 GW of offshore wind power typically exceeds billions of dollars. The specific investment amount depends on the project location, equipment selection, construction period and other factors.
2. Energy production: Offshore wind energy production is related to water depth, wind speed, wind energy density and other location factors. Generally, a 1MW offshore wind turbine can generate around 25 energy. -35 million kilowatt hours per year. Therefore, a 1 GW offshore wind power project can generate on average around 25 to 35 billion kilowatt hours per year.
3. Economic Benefits: The economic benefits of offshore wind power include energy revenues, policy subsidies, reduced carbon emissions and other factors. Generally speaking, the return on investment cycleInstallation takes several years to more than ten years, depending on factors such as the amount of project investment, political support and electricity market prices.
It should be noted that the above data is for reference only, and the specific data should be evaluated according to the actual project conditions.
Small renewable energy power plants include electricity production by direct combustion or gasification of biomass (agricultural and forestry waste), biogas electricity generation, photovoltaic solar energy production, wind power, small hydropower, geothermal power generation, etc. Affected by environment, geographic resources, construction costs, etc., the scale of this type of power station generally cannot be too large. According to the practice of the electrical industry, the cost is expressed as a single costkeep yuan/kw. Environmental conditions vary from place to place, and the cost also varies. The smaller the installed capacity, the higher the unit cost, but there is a general spectrum:
Biomass (agricultural and forestry waste) direct combustion. Power plant: 8,500 to 10,000 yuan/kw
Electricity production by biomass gasification: 11,000 to 15,000 yuan/kw
Biogas power plant: 9,000 at 30,000 yuan/kw (imported equipment is more expensive)
Solar PV power plant: 8.5-10 yuan/Wp (PV power plants are generally small, represented by Wp - peak watt, which can be understood in watts)
Wind power: 8,500-9,000 yuan/kw
Small hydropower: 8,000-12,000 yuan/kw
Geothermal power plant: 12,000-15,000 yuan/kw
