How Much Power Will a Wind Turbine Produce?


Making the switch to wind energy to provide electricity to your home, business, farm, or community is a big step. You stand to benefit greatly from this switch, but you probably have a lot of questions to ask. One of the most common questions asked by those who are considering switching to wind power is how much power will the wind turbine produce. Consumers want to know that switching to wind power will be worth their investment of time and money. Here are some frequently asked questions and their answers regarding the potential power production of wind turbines.

Q. How is the production of power measured for wind turbines?
A. The production of power over time by wind turbines is measured in megawatts-hours (MWh) or kilowatt-hours (kWh). Power that is produced at a rate of 1 MW in 1 hour is equal to 1 MWh.

Q. How is the capacity of wind turbines measured?
A. The capacity of wind turbines to produce power is measured in megawatts (MW).

Q. What is the typical power capacity of a wind turbine?
A. Most current wind turbines have a capacity in the range of 2 – 3 MW.

Q. What factors determine the production capacity of a wind turbine?
A. The production capacity of a wind turbine is determined by the ability of the turbine to capture the energy in the wind, convert the energy to torque, turn the generator, and supply energy to the grid. Several engineering details come into play here. For example, when a turbine is mounted on a taller tower, it can access more stable winds. Also, a turbine that has bigger blades is able to gather more energy. If the turbine has a bigger generator, it necessitates bigger blades and heavier winds.

Q. So…how much energy does a wind turbine produce?
A. This depends on the individual turbine. Each turbine produces its maximum capacity of energy at a given range of wind speeds. This is typically in the range of 30 – 55 mph. When the wind slows, the energy production drops. For example, if the wind speed slows by half, the production of energy drops to an eighth. Therefore, wind turbines do not typically function at their rated capacity. You can expect an energy production of about 30 – 40% of the rated capacity.

Q. What does capacity factor mean?
A. Capacity factor is a measure of the turbine’s actual output as a proportion of the rated capacity.

Q. When is a wind turbine generating energy?
A. A wind turbine generates energy when wind speeds are between 8 mph and 55 mph.

Q. Can a wind turbine create enough energy to fully power a home or business?
A. On average, a wind turbine can create enough energy to provide electricity to more than 300 homes.

Clearly, a wind turbine can provide a large amount of energy to power a home, business, farm, or community. The potential power output is just one of the many benefits of wind power. Wind power is also a clean, renewable source of energy that can provide the electricity that we depend on without damaging the environment.
