Definitions. The following definitions apply specifically to small wind energy systems, as presented in this subsection:
METEOROLOGICAL TOWERA temporary structure erected to collect environmental information for the purpose of assessing the potential for a small wind energy system. The meteorological tower includes the tower, base plate, anchors, guy wires and hardware, anemometers (wind speed indicators), wind direction vanes, booms to hold equipment for anemometers and vanes, data loggers, 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.
MODIFICATIONAny change to the small wind energy system that materially alters the size, type or location of the small wind energy system. Nonstructural maintenance and repair is not considered to be a modification.
NET METERINGThe difference between the electricity supplied to a customer over the electric distribution system and the electricity generated by the customer's small wind energy system that is fed back into the electric distribution system over a billing period.
POWER GRIDThe transmission system, managed by ISO New England, created to balance the supply and demand of electricity for consumers in New England.
SHADOW FLICKERThe visible flicker effect when rotating blades of the wind generator cast shadows on the ground and on nearby structures causing a repeating pattern of light and shadow.
SMALL WIND ENERGY SYSTEMA wind energy conversion system consisting of a wind generator, tower, and associated control or conversion electronics, which has a rated capacity of 100 kilowatts or less and which is used primarily for on-site consumption.
SYSTEM HEIGHTThe vertical distance from ground level to the tip of the wind generator blade when it is at its highest point.
TOWERThe monopole, guyed monopole or lattice structure that supports a wind generator.
TOWER HEIGHTThe height above grade of the fixed portion of the tower, excluding the wind generator.
WIND GENERATORThe blades and associated mechanical and electrical conversion components mounted on top of the tower whose purpose is to convert kinetic energy of the wind into rotational energy used to generate electricity.
