Nantucket High School Wind Turbine

SERVICE:

Noise Analysis for Wind Turbine

DESCRIPTION:

Alteris Renewables of Providence, RI is developing a wind turbine project on the grounds of the Nantucket High School on Surfside Road. A Northwind NW100 wind turbine is planned with a hub height of 37 meters. The Massachusetts Clean Energy Center has awarded the project a grant for turbine installation.

Tech Environmental performed a community sound assessment for Alteris to examine sound impacts in the nearby residential areas. Baseline sound level monitoring was done over a six-day period at six locations. Ten-minute wind speeds were obtained from the meteorological tower at the Nantucket Airport. The Cadna-A acoustic model was applied to predict maximum sound levels in accordance with International Standard ISO 9613-2 for both the cut-in and design wind speed operating conditions. Color-coded decibel contour maps were generated.

Compliance with the Massachusetts DEP Noise Policy and the Nantucket Zoning By-Law was demonstrated at all residential structures.
