Southwest Windpower (SWWP) was a wind turbine manufacturer established in 1987 based in Flagstaff, Arizona, United States.

Southwest Windpower’s latest turbine, the Skystream 3.7, has a rotor diameter of about 12 feet (3.7 m) and can generate up to half an average U.S. home's energy in optimal winds.

It is the first residential-scale wind generator designed specifically for the grid-connected home or small business.

[4] In 2011 the company received a Statement of Compliance from Germanischer Lloyd which confirms that Skystream 3.7 meets the requirements of the IEC Standard 61400-2:2006, Edition 2, "Design requirements for Small wind turbines," which addresses safety philosophy, quality assurance and engineering integrity of the turbine.
