An engineering advancement in simplicity and precision, our Permanent Magnet Direct Drive technology maximizes energy capture and outperforms conventional gearbox designs. Our state-of-the-art power converter design provides smooth, clean power to local grids, simplifying grid interconnect and adding to grid stability to make the Northwind 100 the best choice for a variety of applications.
Northwind 100 Arctic
Not all wind turbines are created equal – especially when it comes to extreme environments such as Arctic conditions. The Northwind 100 Arctic turbine is based on Northern Power Systems’ original Northwind 100 model, which got its start in the cold environs of rural Alaska. Through more than 15 years of operating experience and design enhancements for arctic applications, Northern has created an arctic turbine model that is truly best-in-class for cold and icy environments.
There are many ways in which cold and icy conditions can affect the general operation of a wind turbine. Most electronic devices have operating parameters that do not encompass extreme cold conditions. And if a turbine has a gearbox-laden drive train, it will most likely require specialized hydraulic fluids and heating elements.
Additionally, servicing wind turbines in cold environments can be a significant and costly endeavor. The ability for service personnel to access and check tower bolts and access the technology housed in the nacelle can cost time and money – especially if access avenues are exposed to the elements.
Some of the important features that make our Northwind 100 Arctic turbine a specialized solution for your renewable energy needs:
* Permanent Magnet Direct Drive technology: Northern’s Permanent Magnet Direct Drive technology is designed for superior performance in all environments, but it also forms the basis of superior performance in Arctic conditions in particular.
* Tubular tower: Even though the Northwind 100 Arctic turbine is designed for low maintenance, routine inspections are a much simpler endeavor in cold weather environments.
* Ice-block blade coating: To maximize uptime in cold and icy environments, every Northwind 100 Arctic turbine comes with a specially formulated hydro-phobic polymer coating.
For all of these reasons, our technological advancements and turbine design make the Northwind 100 Arctic turbine the right choice for cold and icy environments.

Transmission lines: High-voltage power lines used to move electricity over relatively long distances from a power generation facility to a substation or other distribution point.
The Benefits of Wind Power
There are numerous wind power benefits. Depending on your specific wind project, some if not all may apply to you:
* Lower overhead: See your electrical costs drop the second your blades start spinning. These savings coupled with state or federal incentive programs can offset your capital costs in several years – allowing you to put more of your profits back onto your operations.
* Energy independence: In addition to the products and services you already offer, you can also produce electricity and take control of your own energy future.
* The “greening” of business: Even a company that is not environmental in nature is valued by discerning consumers who put a premium on sustainable and environmentally friendly business practices.
* Tax advantages: Between the federal investment tax credit and grant program and the rules for claiming depreciation on wind turbines, an investment in wind power today translates to real benefits that you can apply to your bottom line or operating budgets.
* Stable cost of power: You’ll know what your wind-powered electricity costs will be for 20 years or more so you can safeguard yourself against the volatile and increasing costs of energy.
* Educational opportunities: Having a turbine in your backyard – and even the process of planning for it – adds an experiential dimension to your school’s science, math, and civic classes. What better way to train the technicians, engineers, and leaders of tomorrow?
* Green economy: Your wind turbine project – and each new installation it fosters – will bring high-value jobs to your community.
* Marketing opportunities: Whether your business has been around for five years or 50, your Northwind 100 will bring high visibility and a renewed sense of interest in your products and services.
* Meeting RPS goals: Many local governments have enacted Renewable Energy Portfolio Standards to lead their communities into a greener world. When a town erects a community-scale wind turbine, it makes a marked impact on RPS goals and acts as a visible sign of the town’s commitment to clean energy.
Economics of Community Wind Power
We are facing an uncertain energy future. With volatile fuel and electrical costs, people are no longer taking for granted where their power comes from and how rising energy costs will impact their towns, schools, and businesses. In case study after case study, the average cost of power over the lifetime of a wind turbine is dramatically lower than that of traditional sources of power. In short, the power you make is power you don’t have to pay for from other sources.
Power produced locally = Utility costs saved
Now is the time to realize the economic benefits of owning a Northwind 100 turbine:
* Federal and local grants and incentives make wind power work for you. Net metering, local grants, and tax incentives are making wind turbine projects accessible across the country – even “break even” projects are becoming economic imperatives.
* Even in modest wind regimes, wind turbines tend to produce more power than other renewable energy sources. The Northwind 100 was optimized for low wind speeds. It will produce over 100,000 kW hours even in the most modest wind conditions.
* Over the life of a wind turbine, your proposed project will almost always pay for itself. In some cases it takes only several years to realize a payback for your Northwind 100 – after you do, you have years of free power to look forward to.
* A boost to your local economy. Local wind projects bring high-value jobs to your community from contractors to engineering services.
A Step by Step Overview of Wind Power
Installing a Northwind 100 wind turbine involves several steps which address site-specific project issues that impact the approach and cost. In many ways, the process is not unlike developing a home site where you have to take into account many variables from siting to permitting to utility connections. Outlined below is the series of steps that your wind project will move through and the details surrounding each of the steps.
Prior to investing any money into your wind project, it is important to identify your wind resource and utility rate which can help you determine whether or not your intended project makes for a viable wind site. With some basic information provided by you to Northern, our team can craft an initial pre-feasibility report that would offer preliminary wind, energy cost and financial analysis estimates. This initial data should help inform your decision to move forward with your Northwind 100 project
For community wind projects that involve the installation of one or two Northwind 100 wind turbines, it is not necessary to expend the resources for an expansive feasibility study that a wind farm developer might utilize for a multi-million dollar project.
Nevertheless, it is prudent to investigate the following items:
* Identify federal, state, and local incentives available
* Identify all required permits
* Validate the wind resource
* Verify current and anticipated electrical usage patterns at the site
* Identify utility interconnection requirements
As soon as your turbine project is deemed a “go,” it is important to start all the permitting and financing paperwork that is needed. One must develop the project plan sufficiently to support permit applications, incentive grant applications, and the utility interconnection application. Completing civil and electrical system engineering will provide the project with the plans and specifications needed to solicit competitive bids form local suppliers and contractors for the installation work.
The time required for this step can vary dramatically, depending on zoning and permitting requirements. If zoning commission hearings are required with public comment periods, its important to identify that need during the feasibility phase and plan for it. likewise, engaging the local utility regarding the project should be handled as soon as possible as this often has a significant impact on the time and requirements of the project. In general, the longer the process, the more expensive it can be.
Once your wind porject is deemed feasible it is time to purchase your Northwind 100 wind turbine. Due to Northern’s six onth lead time, you should order the major equipment as soon as permits are in hand or are reasonably close to being finalized and financing is in place.
With your turbine ordered it is time to commence the construction phase of your wind project. This step inherently carries the greatest degree of variation because of how varied local permitting requirements can be, how varied site condition can be, and variation in utility interconnection requirements. For instance, site work for foundations may be limited to just clearing a flat spot and digging a hole. Or, in some cases, it may entail creating drainage, retention walls or adding landscaping plans. Your foundation plan can also vary depending on soil conditions. Swampy or rocky sites may require piling or blasting and rock bolting a foundation.
Operations and Maintenance
Equipment installation is relatively straightforward and can take as little as two or three days to erect your Northwind 100 turbine. Your utility will then need to inspect the installation and make sure that it meets testing requirements before it connects your new power source to the grid. Once complete, you will be the proud owner of a Northwind 100 community wind turbine and its numerous benefits will be realized immediately.
As any other capital investment, it will be important for your to consider your regular preventative maintenance schedule and remote monitoring needs. Northern Power Systems i committed to providing our customers a range of advanced support services that ensure optimal turbine operation.
