OpenWind is an open source software application used to model wind farms. Users are able to design wind farms, including wind turbine layout and electrical design. Energy production, turbine noise levels, turbine wake losses, and turbine suitability can be calculated. OpenWind is being developed by AWS Truewind, a wind power consulting company. It is free to download and use, but is currently in an early stage of development. OpenWind is the first and only wind farm modeling software that can be used free of charge.
