Wind FAQs

What would a small wind power system cost?
There are several components to the cost of a system, including the cost of the actual system; installation; the cost of interconnection; and maintenance. The original 5 kW turbine at our Energy Park cost $35,154 installed; the replacement 2.4 kW unit is estimated to cost $20,000 installed. A larger 10 kW system will typically range between $50,000-$75,000, depending on the type and height of the tower. This does not include interconnection and maintenance costs.

Are any incentives available for wind power systems?
There are a number of tax incentives available for renewable energy systems. The US Department of Energy and Database of State Incentives for Renewable Energy websites are excellent resources for current information about federal, state and local incentives.

How much electricity can be generated?
You should first determine how much electricity you want to generate. Based on your current electricity usage, decide how many kilowatt-hours you would like your system to generate, then select a system size to meet your needs.

Consider local conditions in making your choice. The wind speed on your site—at the height at which you intend to erect your wind turbine—is a critical factor in estimating your energy output. Wind speed maps provide estimates, but the wind speed at your location could vary considerably from those. Utilities planning to install commercial turbines collect two years of data on wind speed. Many small wind advocates argue that meteorological data is not necessary for small wind generators. Nevertheless, energy output is directly correlated to wind speed and wind speeds can vary greatly depending on location and height.

Information about the current and historical output of the wind turbine in Midwest Energy Cooperative’s Energy Park can be found at the Energy Park Data Center.

Some states, including Michigan, have net metering rules that restrict homeowners from generating more electricity than they would normally use. Check with your state utility commission for more information.

Does the cooperative buy the extra power I generate?
Midwest Energy Cooperative offers a net metering program. When a consumer uses electricity supplied by the cooperative, the electric meter moves forward. When the consumer’s renewable energy system produces more electricity than the consumer needs at any particular time, the excess is fed back into the grid and the meter rolls backwards. Any excess generation produced during a billing period is credited at the full retail rate (effective July 2009).

How do I get connected to the cooperative grid? Does this cost anything?
Connecting your system to the grid allows you to send excess power to the cooperative. A packet of information outlining the specifics is available from the cooperative by calling 1-800-492-5989, or emailing us at info@teammidwest.com. There is a $100 non-refundable filing fee.

What, if any, permits and inspections are required to operate a wind turbine?
Check with your county planning or permitting department to find out about any zoning regulations and permitting requirements related to renewable energy systems on your property. Homeowners will need to obtain any local permits required before installation.  Typically, your installer will assist you in obtaining permits and clearance from your local officials.

Zoning regulations may limit the height and placement of your wind turbine, so a special-use permit or variance may also be needed. In addition, you may have to submit a structural plan drafted by an engineer, but documents from your turbine manufacturer or dealer may be sufficient.

What kind of payback can I expect in terms of breaking even?
A variety of things will affect your payback period, including the cost of the system and related operational/maintenance expenses, and the output you experience. You can determine your investment payback based on the two systems in our Energy Park by visiting the My Energy Usage tab under our Energy Park Data Center. Simply plug in your meter number and your payback, based on your usage and our system(s), will display.

How reliable are wind turbine systems? Will I have to perform much maintenance?
This really depends on the system you purchase. Most are designed for a long life and operate completely automatically. Proper maintenance will keep your system running smoothly. Most vendors recommend an annual inspection.

Where can I find out more about wind turbines and where to buy them?
There is considerable research and information available to help you learn more about renewable energy technologies. You might start by asking renewable operators in your area for references, or contacting manufacturers of systems you are interested in and asking for a list of authorized dealers. Another option is to ask your state’s renewable energy organization or energy office. The Department of Energy provides contact information for state energy offices at their website.

In terms of up-to-date regional and national information about renewable energy technologies, two great resources are The Midwest Renewable Energy Association (MREA) and the US Department of Energy, Office of Energy Efficiency and Renewable Energy.
