Northern Power Systems is a U.S.-based wind turbine company specializing in permanent magnet direct drive (PM/DD) technology. They have two business segments - Distributed Wind focused on 100kW turbines, and Utility Wind focused on multi-MW turbines like the 2.3MW model. The PM/DD technology enables simpler, more reliable drivetrains compared to traditional geared turbines, reducing operating costs. Analysis shows the NPS 2.3 turbine can improve annual cash flow for a wind farm by $1 million compared to traditional turbines due to increased energy production and uptime, and lower maintenance costs.
