Utility-scale wind turbines (those that are part of large wind development projects) have gotten taller as technology has advanced, which allows access to steadier wind speeds and more efficient energy generation. Most of the existing wind turbines in Michigan were built between 2010 and 2018, and are just under 500 feet tall. Turbines that were constructed earlier than 2010 tend to be about 325-400 feet tall, and newer wind turbines tend to be taller than 500 feet tall.
