This will be the first commercial wind farm in the U.S. to deploy, at scale, turbines that use permanent magnet generators tech-speak for evolutionary turbine technology that will improve efficiency, reliability and grid connection capabilities.

This could be possible as there is tremendous potential for economies of scale, both in terms of mass production, which reduces the cost of each turbine, and in terms of the construction and management of vast wind farms offshore where there are few limits on available acreages.
