AMBIENT. The sound pressure level exceeded 90% of the time or L90.
ANEMOMETER TOWER. A freestanding tower containing instrumentation such as anemometers that is designed to provide present moment wind data.
APPLICANT. The person or entity filing an application under this subchapter.
dB(A). The sound pressure level in decibels. It refers to the “a” weighted scale defined by ANSI. A method for weighting the frequency spectrum to mimic the human ear.
DECIBEL. The unit of measure used to express the magnitude of sound pressure and sound intensity.
FAA. Federal Aviation Administration.
HEIGHT FOR WIND GENERATORS. The height of the wind energy conversion system measured from grade to the tip of the rotor blade or assembly at its highest point or blade tip height.
IEC. International Electrotechnical Commission: the leading global organization that prepares and publishes international standards for all electrical, electronic and related technologies.
ON-SITE USE WIND ENERGY SYSTEM. A land use for generating electric power from wind and is an accessory use that is intended to primarily serve the needs of the consumer at that site.
PEDESTAL. A structure no taller than 12 feet that is designed and constructed primarily for the purpose of supporting one wind turbine.
ROOF MOUNTED. Any part of a wind energy conversion system that is located on the roof of a building, fire or parapet walls, stage lofts, chimneys, smokestacks, water tower or roof structures for the housing of elevators, stairways, tanks, ventilating fans or similar equipment required to operate and maintain a building.
ROTOR. An element of a wind energy system that acts as a multi-bladed airfoil assembly, thereby extracting, through rotation, kinetic energy directly from the wind.
SHADOW FLICKER. Alternating changes in light intensity caused by the moving blade of a wind energy system casting shadows on the ground and stationary objects, such as, but not limited to, a window at a dwelling.
SYSTEM OWNER. The entity or entities having controlling or majority equity interest in the wind energy conversion system, including their respective successors and assignees.
TOWER. Any structure, including its supports, that is ground mounted, taller than 12 feet, and designed and constructed primarily for the purpose of supporting one or more wind energy conversion systems. This includes self supporting lattice towers, guyed lattice towers or monopole towers.
UTILITY GRID WIND ENERGY SYSTEM. A land use for generating power by use of wind at multiple tower locations in a community and includes accessory uses such as but not limited to a SCADA tower, electric substation. A UTILITY GRID WIND ENERGY SYSTEM is designed and built to provide electricity to the electric utility grid.
WIND ENERGY SYSTEM. A land use for generating power by use of wind; utilizing use of a wind turbine generator and includes the turbine, blades and tower as well as related electrical equipment. This does not include wiring to connect the wind energy system to the grid. See also ON-SITE USE WIND ENERGY SYSTEM and UTILITY GRID WIND ENERGY SYSTEM.
