The Cape Wind project is planning to boost annual production of clean wind energy by 7 percent by using more efficient turbines -- specifically the new GE 3.6 Megawatt model xl. The annual expected wind power for the proposed project will now be 1,594,207 megawatt hours (MWh), up from 1,489,200 MWh.
Although the maximum output of the turbines is unchanged at 3.6 megawatts (MW), the new model is more productive during light wind conditions. The new wind turbines are slightly taller than the proposed previous turbines, but the 5 percent increase in height will not noticeably change the visual impact of the project from land.
Cape Wind is also planning to substantially reduce the number of red aviation lights from 260 down to 57, an elimination of 203 lights. This updated aviation lighting plan is consistent with the new wind farm lighting guidelines being used by the FAA.
Previously, each wind turbine was planned to have two red aviation lights; under the new plan, only the wind turbines on the perimeter of the project footprint, and the wind turbines next to the electric service platform, will each have one light on the top of the turbine nacelle.
