NorthWind 100 - 100kW Wind Turbine
The NW100 occupies a vital place in the micro wind market. With many manufacturers now withdrawing from this size of turbine or imposing minimum and prohibitive order quantities (such as 10-15), the NW100 is available in single units and within short time frames.
Supplied on a 30m monopole tower (or taller) the NW100 is potentially suitable for the built environment in which the need to tap into cleaner airflows higher up is essential - we'll keep you posted on our West Ham project in London involving the NW100 on a 37m tower. The NW100 is also supported with noise data conducted to IEC standards. In addition Northern Power are in the process of achieving MCS accreditation, which will be a pre-requisite for eligibility for the Feed in Tariff.
The manufacturers of the NW100, Northern Power Systems, have been designing and engineering wind turbines and power electronics for variable speed direct drive systems since the 1970s. They are a founding member of the American Wind Energy Association (AWEA) and are regularly asked to comment on turbine performance, design and engineering.
NW100 wind turbines are located throughout the world, including the South Pole, the Sahara Desert and the National Renewable Energy Laboratory's National Wind Test Site at Golden, Colorado. Their turbines in Antarctica have successfully operated for almost 20 years in winds up to 88.5 m/s (198 mph) and temperatures as low as -80? C (-112? F).
The technical specification is detailed below and this is also available to download as a PDF file.
