SITING basics to consider:
Remember that siting a turbine properly is important and Ventera Wind promotes good neighbor policies.
Do you have a good wind? Initial indications may be seeing tree flagging, where the trees are leaning predominately in one direction caused by heavy or steady winds. Your Ventera Certified Dealer can assist you in getting more specific data for your area.
Some areas have placed restrictions on wind turbines. Following the basics generally meet the majority of any zoning issues, farms generally are exempt from zoning but checking with your local authorities before contracting is recommended. Your local Dealer may already be aware of any restrictions placed on the land owner or even the local utilities rules on interconnection issues should be known before starting.
Ventera Wind recommends a minimum of 1-2 acres available space for turbine placement. When considering a wind turbine distance is your friend. Distance away from neighbors, buildings, trees and other obstructions are important. Turbulence is created with the uneven flow of air around objects, turbulent air robs you of power and may reduce the life expectance of you turbine as the uneven air flow is much harder on wind turbines. The turbines bottom blade should be 30’ above any obstruction or a 1000’ away if at the same height.
Creating a shadow from the turbines turning blades always needs to be considered when placing a wind turbine. Nobody wants a shadow of the rotating blades coming through their dining room window every night as their eating. Shadows change according to the time of year and part of our good neighbor policy is to ensure that no shadows are reflecting on a neighbors’ home.
Experience has taught us that tower failures are a very rare occurrence. We have made every effort as a company to mitigate the risk of a tower failure with proper engineering. That being said some areas have setback requirements of 110% to 125%. Basic rules dictate in the event of a catastrophic failure the turbine should fall on the owners’ property and should not be able to hit an occupied structure where people may be at rest.
The U.S. Department of Energy 30 meter/90 foot wind map is a good place to start.
Macro-siting refers the general area a wind turbine could be located and the overall quality of winds. Micro-siting deals with the specific property and wind turbine and the quality and direction of the winds, any obstructions or terrain issues that would negatively affect the performance of a wind turbine system.
