The construction cost of thermal power plants is relatively low, 200 million yuan is enough, except in urban areas where land prices are high, 300 million yuan is possible. Or the underground conditions are not good, such as silt salt flats. Underground treatment is more troublesome, but it will not exceed 200 million.
The cost of wind power is higher, 350 million yuan in plains and mountainous areas, and the cost of offshore wind power is higher, 450 million to 500 million yuan.
Small renewable energy power plants include biomass (agricultural and forestry waste) direct combustion or gasification power generation, biogas power generation, solar photovoltaic power generation, wind energy, small hydropower, geothermal energy power generation, etc. Affected by the environment, geographical resources, construction costs, etc., the scale of this type of power plant generally cannot be made too large. According to the practice of the power industry, the cost is expressed in unit cost 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-fired power plant: 8500 —10,000 yuan/kw
Biomass gasification power generation: 11,000-15,000 yuan/kw
Biogas power station: 9,000-30,000 yuan/kw (imported equipment is more expensive)< /p>
Solar photovoltaic power station: 8.5-10 yuan/Wp (photovoltaic power stations are generally small, represented by Wp - peak watt, which can be understood as watts)
Wind power: 8500-9000 yuan /kw
Small hydropower: 8,000-12,000 yuan/kw
Geothermal power station: 12,000-15,000 yuan/kw
