Electricity Generating Wind Systems
(Small Wind = less than 100kW)


Wind power can be an effective, cost-efficient and environmentally responsible way to meet your energy needs. Wind is an increasingly good investment. Financial incentives, such as income tax deductions, federal and state grants, property tax exemptions, rebates, production tax credits, and green credits may be available to help reduce costs. A properly maintained wind turbine will generate energy for decades to come and is a good investment for your family or business. See - Wind Video

With over 25 years experience installing and servicing small wind turbines of many types WERC offers planning services for small wind turbine owners, includes detailed itemizing of all costs and paybacks.

Payback Considerations:
1) Typical payback for a business is 5-9 years, a farm 6-12 years, - a home 8-20 years
2) Special tax deductions exist
3) Grant funds may be available

WERC Provides These Services:

  • Site planning for optimal placement of towers and ROI
  • Sizing, permits, and product sourcing
  • Construction of towers, mounting, wiring, testing
  • Maintenance and service work on small wind machines

Wind Turbine Site Plans by WERC Provide:

  • Necessary information for the wind turbine owner to assess the feasibility of installation costs for the entire project, paybacks, incentives maintenance, insurance, interest costs and other considerations over a 20 year period showing the cash flow and ROI.
  • Provides power company interconnection agreements.
  • Provides virtual pictures of what the turbine will look like on-site, prior to installation.
  • Provides information necessary for building permits.

For a service fee, WERC will visit your site to conduct the measurements, take
photos and provide you with a binder full of technical details on the systems, installation process and guarantees. See Site Plan Details

How Is Your Wind Density?
The Department of Energy measures wind power on a scale of 1 (weakest) to 7. If winds on your site are at least class 2 (annual wind speeds averaging 9.8 to 11.5 mph), it may be suitable for wind generation.

For wind energy information, legislation and wind speed maps for each state in the Northwest United States go to www.undeerc.org - States included are Colorado, Illinois, Iowa, Kansas, Minnesota, Missouri, Montana, Nebraska, North Dakota, Oklahoma, South Dakota,Wisconsin and Wyoming.

Please remember that wind maps give only broad estimates -- the wind speed on any particular site is largely determined by terrain. Consult WERC to more thoroughly research your wind resource.

Do You Have the Clearance?
A good small wind turbine site is typically at least one acre in size. Turbines must be mounted at least 30 feet above any physical wind barriers (i,e., trees, buildings, or bluffs) within 300 feet to avoid air turbulence. Winds are faster at higher elevations, and wind power increases by a factor of three as speed increases, so even a small boost in height greatly enhances a turbine's output.

Most small wind turbine manufacturers recommend mounting turbines at least 65 feet high, but particular site conditions should be the primary factor when determining tower height. Towers from 80 to 120 feet tall may be optimal.

Zoning restrictions on your site may limit the allowable tower height, requiring you to seek a conditional use permit or variance from your city or county planning department. Local authorities have the discretion to issue zoning waivers for small turbines where appropriate.


  • Residential Renewable Energy Tax Credit - Maximum Federal Incentive Small Wind: $500 per 0.5 kW, up to $4,000. More information
  • Many utilities institute a policy called “net metering” whereby the extra electricity is sold back to the utility. How does Net-Metering Work?
