WIND ENERGY TURBINES
The purpose of this article is to establish guidelines for siting wind energy turbines (WETs). The goals are as follows:
(1)
To promote the safe, effective, and efficient use of a WET in order to reduce the consumption of fossil fuels in producing electricity.
(2)
To preserve and protect the public health, safety, welfare, and quality of life by minimizing the potential adverse impacts of a WET.
(3)
To establish standards and procedures by which the siting, design, engineering, installation, operation, and maintenance of a WET shall be governed.
Ambient sound level means the amount of background noise at a given location prior to the installation of a WET which may include, but not be limited to, traffic, machinery, lawnmowers, human activity, and the interaction of wind with the landscape. The ambient sound level is measured on the dB(A) weighted scale as defined by the American National Standards Institute.
Anemometer means a temporary wind speed indicator constructed for the purpose of analyzing the potential for utilizing a wind energy turbine at a given site. This includes the tower, base plate, anchors, cables and hardware, wind direction vanes, booms to hold equipment, data logger, instrument wiring, and any telemetry devices that are used to monitor or transmit wind speed and wind flow characteristics over a period of time for either instantaneous wind information or to characterize the wind resource at a given location.
Condominium development means a development that is created under the Condominium Act.
Decibel means a unit of measure used to express the magnitude of sound pressure and sound intensity. Decibels shall be measured on the dB(A) weighted scale as defined by the American National Standards Institute.
Decommissioning means the process of terminating operation and completely removing a WET and all related buildings, structures, foundations, access roads, and equipment.
General common element means an area designated for use by all owners within condominium development.
Large wind energy turbine (LWET) means a tower-mounted wind energy system that converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. The LWET has a nameplate capacity above 250 kilowatts.
Medium wind energy turbine (MWET) means a tower-mounted wind energy system that converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. The MWET has a nameplate capacity that does not exceed 250 kilowatts.
Nacelle means the encasement which houses all of the generating components, gear box, drive tram, and other equipment.
Net-metering means a special metering and billing agreement between utility companies and their customers which facilitates the connection of renewable energy generating systems to the power grid.
Occupied building means a residence, school, hospital, church, public library, business, industrial building or any other building used for public gatherings or work.
Operator means the entity responsible for the day-to-day operation and maintenance of a wind energy turbine (WET).
Owner means the individual or entity, including their respective successors and assigns, that have an equity interest or own the wind energy turbine (WET) in accordance with this ordinance.
Rotor diameter means the cross-sectional dimension of the circle swept by the rotating blades of a WET.
Shadow flicker means the moving shadow, created by the sun shining through the rotating blades of a wind energy turbine (WET). The amount of shadow flicker created by a WET is calculated by a computer model that takes into consideration turbine location, elevation, tree cover, location of all structures, wind activity, and sunlight.
Small structure-mounted wind energy turbine(SSMWET) converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. A SSMWET is attached to a structure's roof, walls, or other elevated surface. The SSMWET has a nameplate capacity that does not exceed five kilowatts. The total height of a SSMWET shall not exceed ten feet as measured from the highest point of the roof, excluding chimneys, antennae, and other similar protuberances.
Small tower-mounted wind energy turbine (STMWET) means a tower-mounted wind energy system that converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. The STMWET has a nameplate capacity that does not exceed 30 kilowatts. The total height of a STMWET shall not exceed 120 feet.
Structure means any building or other structure, such as a municipal water tower that is a minimum of 12 feet high at its highest point of roof and is secured to frost-footings or a concrete slab.
Total height means the vertical distance measured from the ground level at the base of the tower to the uppermost vertical extension of any blade, or the maximum height reached by any part of the wind energy turbine (WET).
Tower means a freestanding structure that supports a wind energy turbine (WET). A tower shall not be erected without a building permit.
Upwind turbine means a wind energy turbine (WET) positioned in a manner so that the wind hits the turbine blades before it hits the tower in order to avoid the thumping noise which can occur if the wind is disrupted by hitting the tower before the blades.
Wind energy turbine(WET) means any structure-mounted, small, medium, or large wind energy conversion system that converts wind energy into electricity through the use of a wind generator and includes the nacelle, rotor, tower, and pad transformer, if any.
