[email protected] [email protected] Garden Peninsula Wind Energy Project, Delta County, MI Phase I Avian Risk Assessment Garden Peninsula Wind Energy Project Delta County, Michigan Executive Summary Heritage Sustainable Energy is proposing a utility-scale wind-power project of moderate size for the Garden Peninsula on the Upper Peninsula of Michigan in Delta County. This peninsula separates northern Lake Michigan from Big Bay de Noc. The number of wind turbines is as yet undetermined, but a leasehold map provided to Curry & Kerlinger indicates that turbines would be constructed on private lands (i.e., not in the Lake Superior State Forest) in mainly agricultural areas on the western side of the peninsula, and possibly on Little Summer Island. For the purpose of analysis, we are assuming wind turbines with a nameplate capacity of 2.0 MW. The turbine towers would likely be about 78.0 meters (256 feet) tall and have rotors of about 39.0 m (128 feet) long. With the rotor tip in the 12 o’clock position, the wind turbines would reach a maximum height of about 118.0 m (387 feet) above ground level (AGL). When in the 6 o’clock position, rotor tips would be about 38.0 m (125 feet) AGL. However, larger turbines with nameplate capacities (up to 2.5 MW and more) reaching to 152.5 m (500 feet) are may be used.
