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. For the purpose of this ordinance, met towers shall refer only to those whose purpose are to analyze the environmental factors needed to assess the potential to install, construct or erect a small wind energy system.
Any change to the small wind energy system that materially alters the size, type or location of the small wind energy system. Like-kind replacements shall not be construed to be a modification.
The 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.
The transmission system, managed by ISO New England, created to balance the supply and demand of electricity for consumers in New England.
The visible flicker effect when rotating blades of the wind generator cast shadows on the ground and nearby structures causing a repeating pattern of light and shadow.
A wind energy conversion system consisting of a wind generator, a tower, and associated control or conversion electronics, which has a rated capacity of 100 kilowatts or less and will be used primarily for onsite consumption.
Means the vertical distance from ground level to the tip of the wind generator blade when it is at its highest point.
The monopole, guyed monopole or lattice structure that supports a wind generator.
The height above grade of the fixed portion of the tower, excluding the wind generator.
The 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.
The setback for small energy system towers shall be equal to one and one-half (1½) times the proposed system height. Small wind energy systems must meet all setbacks for principal structures for the zoning district in which the system is located.
The maximum system height shall be restricted to 35 feet above the tree canopy within 300 feet of the small wind energy system. In no situation shall the system height exceed 150 feet.
The combined sound level of all small wind energy systems on a site shall not exceed 55 decibels using the A scale (DBA), as measured at the site property line, except during short-term events such as severe wind storms and utility outages.
Small wind energy systems shall be sited in a manner that does not result in shadow flicker impacts offsite. The applicant has the burden of proving that the shadow flicker will not be visible to neighboring or adjacent uses. Potential shadow flicker will be addressed either through siting or mitigation measures.
All signs including flags streamers and decorative items, both temporary and permanent, are prohibited on the small wind energy system, except for manufacturer identification or appropriate warning signs.
The small wind energy system shall comply with all applicable sections of the New Hampshire State Building Code.
The small wind energy system shall be built to comply with all applicable Federal Aviation Administration regulations including but not limited to 14 C.F.R. part 77, subpart B regarding installations close to airports, and the New Hampshire Aviation regulations, including but not limited to RSA 422-b and RSA 424.
It is inherent that small wind energy systems may pose some visual impacts due to the tower height needed to access wind resources. The purpose of this section is to reduce the visual impacts, without restricting the owner’s access to the optimal wind resources on the property.
The total combined output capacity of all small wind energy systems on a single lot must not exceed 100 kw.
The manufacturer and model of the wind generator to be used in the proposed small wind energy system must have been approved by the California Energy Commission or the New York State Energy Research and Development Authority, or a similar list approved by the state of New Hampshire, if available.
If the proposed small wind energy system is to be connected to the power grid through net metering, it shall adhere to RSA 362-A:9.
The tower shall be designed and installed so as not to provide step bolts or a ladder readily accessible to the public for a minimum height of 8 feet above the ground. All ground-mounted electrical and control equipment shall be labeled and secured to prevent unauthorized access.
Clearing of natural vegetation shall be limited to that which is necessary for the construction, operation and maintenance of the small wind energy system and as otherwise prescribed by applicable laws, regulations, and ordinances.
All small wind energy systems, their towers and associated equipment shall be subject to site plan review and approval by the Planning Board. Site plan review by the Planning Board shall be required for any physical modification to an existing small energy wind system. MET towers that receive site plan approval shall be permitted on a temporary basis not to exceed three (3) years from the date the building permit to construct the MET Tower was issued.
An application with designs for towers, additional support features and all associated facilities and accessories shall be submitted to the Planning Board. Applications shall contain a site plan with the following information:
When considering applications for the construction and operation of small wind energy systems, the Planning Board and the Board of Adjustment will consider factors including, but not limited to:
Public notification will be in accordance with the Site Plan Review Process.
The applicant shall post a bond to cover the cost of removal of the small wind energy system and site restoration in the event of abandonment.
At such time that a small wind energy system is scheduled to be abandoned or discontinued, the applicant will notify the planning board and building inspector by certified U.S. mail of the proposed date of abandonment or discontinuation of operations.
Upon abandonment or discontinuation of use, the owner shall physically remove the small wind energy system within 90 days from the date of abandonment or discontinuation of use. This period may be extended at the request of the owner and at the discretion of the building inspector. “Physically remove” shall include, but not be limited to:
In the event that an applicant fails to give such notice, the system shall be considered abandoned or discontinued if the system is out-of-service for a continuous 12-month period. After the 12 months of inoperability, the building inspector may issue a Notice of Abandonment to the owner of the small wind energy system. The owner shall have the right to respond to the Notice of Abandonment within 30 days from Notice receipt date. After review of the information provided by the owner, the building inspector, with consultation from the Planning Board, shall determine if the small wind energy system has been abandoned. If it is determined that the small wind energy system has not been abandoned, the building inspector shall withdraw the Notice of Abandonment and notify the owner of the withdrawal.
If the owner fails to respond to the Notice of Abandonment or if, after review by the building inspector, it is determined that the small wind energy system has been abandoned or discontinued, the owner of the small wind energy system shall remove the wind generator and tower at the owner’s sole expense within 3 months of receipt of the Notice of Abandonment. If the owner fails to physically remove the small wind energy system after the Notice of Abandonment procedure, the building inspector or Board of Selectmen may pursue legal action to have the small wind energy system removed at the owner’s expense.
