How much power is normal for a base station wind power source to consume

The data suggest that the turbine consumes at a minimum rate of about 50 kW, or 8.3% of its reported production over those years (which declined 2-4% each year). There is also the matter of reactive power (VAR). As wind facilities are typically built in remote areas, they are often called upon to provide VAR to maintain line voltage.

For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year — less if the wind isn't blowing reliably. Industrial scale turbines usually have capacity ratings of 2 to 3 megawatts.

The largest wind turbine in operation produces just over eight megawatts of power. The biggest offshore wind farm in the world, Hornsea One, located in the North Sea off the Yorkshire coast, consists of 174 wind turbines of seven megawatts. Overall the wind farm generates 1.2 gigawatts of power. What would 1.2 gigawatts power?

An eight megawatt offshore wind turbine would generate 8,000 kW (kilowatts) when it is operating at its maximum capacity. So it would be able to supply 16,000 homes at a rate of 500 watts each. How many wind turbines are there in the UK? At the moment there are 2,000 offshore wind turbines in the UK waters.

What is documented however [31, 96–99] is that wind turbines require primary life-cycle embodied energy amounts in the order of only 1–3 MWh kW −1 (that usually implies energy payback periods of months), with the stage of manufacturing being the most demanding.

A single 12 MW offshore turbine can produce 45 to 50 million kWh per year, supporting the electricity needs of nearly 12,000–15,000 households. Several other factors influence real-world output: Average Wind Speed: Power output increases exponentially with wind speed (the power output is proportional to the cube of wind speed).
