About this file
This document contains a specification sheet for a wind turbine system and a related federal contract opportunity notice. The specification sheet provides technical details for a 20kW fiberglass/resin horizontal axis upwind wind turbine with a 10 meter diameter rotor, including cut-in and rated speeds, emergency braking systems, generator and controller specifications, tower height options between 21.3 and 36.6 meters, and environmental operating limits from -25C to 50C. The related federal contract opportunity is a solicitation from the Department of the Army Michigan Army National Guard seeking renewable energy systems for the Virgin Islands, with a bid opening date to be determined and to be held at the Selfridge Air National Guard Base in Michigan. Site visits to St. Croix are also specified.
