ArborWind

ArborWind designs and builds the PT180, a vertical axis wind turbine intended for urban, industrial, agricultural and off-grid sites. The company says its patented design is simpler to manufacture, install and maintain than horizontal turbines, and it has an installation that ran for eight years outside Marshall, Michigan. Founder Dilip Nigam leads the company, which was started in 1986 according to our records.

The company is based in Ann Arbor, where it works with Michigan and U.S. suppliers. Customers interested in the turbines can request information through the website or by phone. The team also works on the investment side of wind power, and the company lists a PT180 installation in a dense urban setting.
