How would the turbines be spaced and marked to make them visible to airplane pilots and mariners?
Cape Wind’s turbines would be up to 420 feet high with a hub height about 260 feet above the water surface. They would be arranged in a grid with spaces measuring 0.34 by 0.56 nautical miles (629 by 1,000 meters) in between turbine towers. Each generator would have two flashing lights on the lower platform to warn shipping; additionally, those towers around the perimeter of the park would have red aviation warning lights on the nacelle (generator cover). The park’s lighting plan was designed in consultation with the Coast Guard, the Federal Aviation Administration, and the Army Corps of Engineers.
