Wind Energy
New Zealand is fortunate to have excellent wind energy resources, some of which are among the best locations in the world for wind farms. Nationwide, potential capacity factors for potential sites with the capacity to build wind power plants range from approximately 35% to 45%. Taking a typical example with a net capacity factor of 40%, this statistically means that only 40% of the installed wind turbine's production capacity can provide reliable production in a year.
Due to the intermittent nature of natural wind, the actual power generation capacity varies from 0% to 100% of the installed capacity, which is subject to the erratic behavior of wind power. For many wind farms, local differences in wind speed regimes generally provide some generation capacity. Although the cost of capacityinstalled wind power plants decreases and is similar to that of current coal-fired electricity generation (in yuan/MW), the cost of truly safe electricity generation capacity is very high.
Compared to a solid energy coal-fired power plant, a 150 MW coal-fired power plant is expected to have a net capacity factor of 90%, resulting in an annual electricity production of 1,182,600 MWh (90% net capacity factor x 8,760 hours/year x 150 MW). For a wind farm to provide comparable stable generation capacity, the installed size of the wind farm would require 337.5 MW (1,182,600 MWh/8,760 hours/year/40% net capacity factor). The real cost of a stable wind power plant compared to a coal-fired power plant is therefore 2.25 times higher than the actually installed capacity (337.5 MW of wind energy / 150 MW of coal). A typical wind farm has a production capacity of approx.ron 15 megawatts per square kilometer. This would require 2,250 hectares of windswept ridges. This equates to a ridge area 1 kilometer wide and 22.5 kilometers long. Although this seems like a large area, the impact of wind farms on continuously used land is minimal, as wind turbines, roads and transmission lines only occupy 2% of the total land area. The aforementioned solid energy coal-fired power plant will occupy a land area of 60 hectares, 1/3 of which will be used to store coal fuel and power plant equipment. The remainder of the land is primarily used for greening, providing a green buffer zone for the public.
Wind power generation also has its opponents, with some projects such as Awhitu (Manuaka Heads, Auckland), Quartz Hill (Makara, Wellington) and Baring Head (Wellington) failing due to lack of resources. Fortunately,Perceived issues such as visual, aesthetic and noise issues have not stopped wind projects from continuing to develop, such as the Te Apiti and Manawatu wind farms.
How much electricity can wind power produce per day? Your question is too general to answer.
But I can give you a rough estimate: currentlyThe average effective power production time of a wind power generation device over the course of a year is around 2,000 hours, this which means that the average duration of electricity production is 5.48 hours per day. By multiplying 5.48 hours by the installed capacity of a certain wind turbine, you can easily calculate the average energy production of that generator in a day. For example, a standard 3 MW wind turbine generates an average of 16,440 kilowatt hours (Kwh) of electricity each day.
