Even so, the mainstream technology used in most wind turbines today is not always the best fit for specialized environments. Arctic conditions where temperatures reach below -200 C (-4° F) and ice buildup is common, can negatively impact wind turbii operations. Demanding environments require specialized and that is why Northern Power Systems has designed tl, Northwind 100 Arctic Turbine. Public Schools • Small Businesses • Farms 6 Dairies • Municipal Buildings Superior by design —Proven through experience Northern Power Systems knows extreme environments. Our early HR3 turbine model has survived 198 mph winds and -600 C temperatures in Antarctica and still continues to operate. We have shipped more than 20 turbines into Alaska and have produced over 3.8 million kilowatt hours to date. Based on over 30 years of proven wind experience, the Northern team has created an arctic turbine model that is truly best in class for cold and icy environments. The Northwind 100 Arctic turbine shares a number of the advanced design elements that make Northern's standard Northwind 100 the ideal turbine choice in mainstream markets. Additional features and design enhancements in this specialized model ensure optimum performance for your wind project no matter the frigid conditions —so that you can achieve your renewable energy goals whether you are located in the tundra or the Alps. Greenhouses • Universities • Corporations • Hotels & Resorts • Libraries & L8 .I The right technology: Permanent Magnet Direct Drive (PMDD) Northern's PMOO technology is designed for superior performance in all environments. hilt Ir atcn fnrmc tho basis of our superior performance in Arctic conditions. >) Low maintenance: Our PMDD technology and simple design architecture are why the Northwind 100 Arctic requires only minimal preventative maintenance —once per year. In this way you can set your maintenance schedule to avoid particularly harsh seasons. Additionally, the gearless technology bypasses much of the long-term maintenance issues that are associated with the more conventionally designed gearbox turbines. )> Better energy capture: All turbines can make more power in cold environments, but Northern has developed an advanced design and control system that takes advantage of the high air densities associated with very cold temperatures. The Right Options Aside from the obvious benefits of choosing a turbine that has been optimized to operate specifically for your cold weather region, we also offer remote monitoring and wind diesel options. >) SmartView Products: our web based monitoring and reporting platform supports a range of options —from reporting, supervisory controls, and turbine monitoring from your PC to remote diagnostics services from Northern Power Systems —to ensure optimum turbine performance and avoiding unnecessary service calls. )> Wind Diesel: our state-of-the-art turbine combined with our advanced control systems and years of expertise allow for the seamless integration into your diesel grid, enabling utilities to save fuel, cut emissions, and reduce diesel maintenance. Malls • Island Communities • Ski Resorts • Churches • Town Offices • Rural Utilities Customized blades for icy conditions Like most other turbines, the Northwind 100 Arctic has a safety feature that automatically shuts the turbine off when too much ice has built up on the blades. But each moment that turbines are not operating translates to lost power and money. To maximize uptime in cold and icy environments, our blades come with a specially formulated hydro phobic polymer coating ensuring a smooth surface so ice cannot easily build up on the blades. If ice does form, our black blades absorb the sun's heat and allow for ice to be shed easily.

Now residents of Kasigluk and Nunapitchuk are paying 12 cents less, thanks to the wind turbines." ;; KOHLER, CEO AND PRESIDENT, AVEC AVEC is a non-profit electric utility owned by the residents of 53 remote villages throughout western Alaska. To power these homes. AVEC used more than 150 diesel generators that cumulatively ran more than 400,000 hours per year —equaling 950 diesel truck trips around the world. The five million gallons of diesel fuel used to power these villages was stored in bulk fuel tank facilities that needed regular maintenance, repairs, and upgrades. With skyrocketing fuel prices and storage expenses, electricity became so expensive that villagers often had to make difficult decisions between powering their homes and purchasing food. That's why AVEC took the bold initiative to start introducing wind power to some of the remote villages that it serves.
