CLEAR AREA
The area of a circle centered on the center of the Tower
and having a radius equal to the Total Height as defined below.
COMMERCIAL-SIZE WECF
A wind energy conversion facility (WECF) having a rated electrical power output greater than 10 kilowatts, other than a Municipal WECF as defined below. (Commercial-size WECFs are not covered by this By-law; see Article
41 of the Zoning Bylaws.)
HAWT
Horizontal-axis wind turbine.
HUB HEIGHT
The height of a HAWT measured vertically from the natural
grade at the base of the Tower to the centerline of the Rotor.
MUNICIPAL WECF
A wind energy conversion facility (WECF) located on Town-owned
property designed to provide at least 50% of its electrical output,
or of the value thereof, for the use or benefit of the Town of Dartmouth
and without regard to the ownership of the structure or equipment.
NACELLE
The frame and housing at the top of a HAWT Tower that encloses
the gearbox, generator, and other accessories, and protects them from
the weather.
PLACE OF BUSINESS
A business establishment open to the general public, but
not including business establishments, operations or plants owned,
controlled, operated or managed by the Town of Dartmouth.
RESIDENTIAL-SIZE WECF
A wind energy conversion facility (WECF) having a rated electrical power output less than or equal to 10 kilowatts, other than a Municipal WECF as defined above. (Residential-size WECFs are not covered by this Bylaw; see Article
40 of the Zoning Bylaws.)
ROTOR
The blades and hub of the wind turbine that rotate during
turbine operation.
TOTAL HEIGHT
The height of a HAWT measured from the natural grade at the
base of the Tower to the tip of a blade at its highest point, or the
maximum height of a vertical-axis wind turbine (VAWT).
TOWER
The structure that supports the turbine, Rotor, generator,
and accessory equipment. The tower may be a monopole or lattice design,
with or without guy wires depending on the height and other factors.
VAWT
Vertical-axis wind turbine; sometimes called a Darrieus-type
wind turbine.
WIND ENERGY CONVERSION FACILITY (WECF)
All equipment, machinery and structures used in connection
with the conversion of wind energy to electricity. This includes,
but is not limited to, all transmission, storage, collection and supply
equipment, substations, network of cabling, transformers, site-access
and service roads, and machinery associated with its use. A wind energy
conversion facility may consist of one or more wind turbines.
WIND MONITORING OR METEOROLOGICAL (MET) TOWER
Tower used for supporting anemometers, wind vanes and other equipment to assess the wind resource at set heights above the ground. (Wind monitoring or MET towers are not covered by this Bylaw; see Article
40 of the Zoning Bylaws.)
WIND TURBINE
Any electromechanical device that converts kinetic energy
of the wind into rotational energy to turn an electrical generator
shaft. Wind turbines usually consist of a horizontal-axis rotor, Nacelle
and supporting Tower (HAWTs). Both HAWTs and VAWTs are covered by
this Bylaw.
The provisions of this Bylaw are severable. If any provision
of this Bylaw is held invalid, the other provisions shall not be affected
thereby. If the application of this Bylaw or any of its provisions
to any person or circumstance is held invalid, the application of
