The annual power generation of a 200 000 kilowatt wind farm

How much energy does a wind farm produce a year?

The wind farm’s annual energy production (AEP) in the first 12-month period was 39,599 MWh, compared to 36,864 MWh in the second year. The second year’s reduction in energy production is mainly due to the lower mean wind speed.

How many kilowatts does a wind turbine produce?

Individual wind turbines are typically grouped together to give rise to a wind farm (Figure 1). A single wind turbine can range in size from a few kilowatts (kW) for residential applications to more than 5 Megawatts (MW)2. Many wind farms are producing energy on a megawatt (MW) scale, ranging from a few MW to tens of MW.

Why is annual wind farm energy production important?

Annual wind farm energy production is vital for planning and performance evaluation. Wind turbine output power derate at high air temperatures resulting in power losses. Planning wind project in a hot environment requires temperature data at hub height. Weibull parameters changes significantly during high temperature conditions.

What is the capacity factor of a wind farm?

The capacity factor for a wind farm is determined by the average wind speed at the location and the hub height. The energy that can be harvested is also a function of the swept rotor area. Thus, tall turbines with larger rotor areas in high average mean wind speed areas will have the highest capacity factors and energy yields.

What is the theoretical power captured by a wind turbine?

The theoretical power captured (P) by a wind turbine is given by The power production of a wind turbine (WT) thus depends upon many parameters such as wind speed, wind direction, air density (a function of temperature, pressure, and humidity) and turbine parameters .

How accurate are wind turbines' annual energy production (AEP) estimates?

Accurately estimating wind turbines' annual energy production (AEP) is a paramount for planning and performance assessment of wind power projects. Inaccurate estimates during the planning phase could result in lower/higher project economic feasibility. This leads to financial consequences in the project’s contractual agreement.
