Plymouth North High School Wind Turbine Project Model High School Site 41 Obery Street Plymouth, MA
Project History • Atlantic Design Engineers, LLC (Atlantic) conducted an initial wind turbine siting and feasibility analysis of the PNHS property. • Atlantic completed a series of studies to obtain a better understanding of the impacts associated with a turbine in this location including: • Shadow Flicker Impact Study • Photosimulations from various locations around the site • Zone of Visual Influence (ZVI) Map • Atlantic then completed a noise monitoring program and Acoustic Analysis to determine the background (ambient) noise levels at various locations surrounding the site; and selected a representative turbine (900kW EWT) to acquire a better understanding of the specific acoustic impacts the project may have on nearby residential neighborhoods.
Energy Production Estimates Energy production numbers are based on the following: • Predicted Wind Resource: • 5.4 m/s at 40 m (131’) AGL • 5.7 m/s at 55 m (180’) AGL • 6.4 m/s at 75 m (246’) AGL • Annual energy production loss factor of 8% • 75 m EWT 54-900: 900 kW Rated Capacity: 2,124,000 kWh/year* • 71 m Gamesa G58: 850 kW Rated Capacity: 2,117,000 kWh/year • 55 m Aeronautica 54-750: 750 kW Rated Capacity: 1,604,000 kWh/year • 40 m Aeronautica 29-225: 225 kW Rated Capacity: 313,000 kWh/year *: Model used to complete Shadow Flicker, Visual, and Noise Impact Assessments
