Where is the project?

The Aurora Wind Project is located approximately 5 miles Northwest from Tioga, North Dakota and is mostly located within Williams County.


What transmission line does the project connect with?

The project currently has multiple interconnection options. The project plans to connect into the new Tande Substation located on the Northeastern edge of Tioga.


What is the size of the project?

Up to 300 MW


Landowners and Acreage Involved:

Aurora encompasses approximately 55,000 acres and consists of over 50 landowners.


Who is buying the power?

The power produced by the Aurora Wind Project will be marketed to local and regional electric utilities.


Who developed the project?

The developer of the Cheyenne Ridge Wind Project is Tradewind Energy, Inc.


What will the Project’s economic impact be on the local area?

The Project will pay an average of nearly $4 million per year in property tax and landowner rent payments. The Project will also employ more than 200 workers during the construction phase, with the fully operational Project requiring up to 10 full-time workers.


Will the Project facilities be removed once the Project is no longer operational?

Once the Project is no longer operational, the Project will be decommissioned and facilities removed in accordance with the wind energy leases, the North Dakota Public Service Commission’s decommissioning rules, and the Williams County Zoning Ordinance decommissioning requirements. In accordance with Section 69-09-09-06 of the North Dakota Administrative Code, a decommissioning plan for the Project will be filed with the North Dakota Public Service Commission before the Project is placed in service.


What are your setbacks from homes?

Wind turbines will set back from occupied structures (homes, businesses, etc.) a minimum distance of 1,400 feet.


How much sound do the turbines create?

As a mechanical device, wind turbines do produce sound which decreases with distance from the turbine. Even at the base of a modern wind turbine, two people can carry on a conversation in a normal speaking voice, and at greater distances the sound of the turbine is usually drowned out by the sound of the wind itself.  The North Dakota Public Service Commission’s siting rules require that wind turbines be sited so that sound levels within 100 feet of an inhabited residence or community building do not exceed 50 dBA, which is approximately as loud as hearing a car two miles away drive down a highway. The Project will comply with this requirement, and most residences will experience sound levels far quieter than this level.


What is shadow flicker?

Shadow flicker occurs when the blades of a rotating wind turbine are directly between an observer and the sun, causing alternating light and shadow.  This effect decreases and ultimately disappears with distance from the turbine and is also eliminated by obstacles between the observer and the turbine, such as trees or terrain, and is not present at all on cloudy days. Scientific research has continually concluded that shadow flicker is harmless, though it may be considered by some to be an annoyance.  Therefore, Tradewind considers shadow flicker on all projects we design and will work to keep occurrences to a minimum at occupied structures.


Will the Project impact property values?

Numerous studies have shown that wind power does not negatively affect property values long-term. In fact, wind power actually benefits property owners by driving community economic development. A study on wind farms and property values conducted by the Lawrence Berkeley National Laboratory and released in August of 2013 analyzed more than 50,000 home sales near 67 wind facilities across nine U.S. states and did not identify any impacts to nearby home property values.


Are there health hazards associated with living around a wind project?

Public health is one of the great advantages of wind power. Numerous peer-reviewed, publicly-funded, scientific studies have shown no ill effects from living near wind turbines. Wind energy is an inexhaustible resource that generates no pollution or hazardous waste, does not deplete fresh water resources, and requires no mining, transportation, or refining of a feedstock or fuel.


Who is Tradewind Energy?
