How tall are commercial wind turbines

The widely used GE 1. The blades sweep a vertical airspace of just under an acre. The 1. Another model being seen more in the U.

Many existing models and new ones being introduced reach well over feet in total height. See the specs for several models at AWEO. How are the wind turbine components transported? Transport of such large items and the cranes needed to assemble them often presents problems in the remote areas where they are typically built.

Roads must be widened, curves straightened, and in wild areas new roads built altogether. What kind of platform is a wind turbine set in? The steel tower is anchored in a platform of more than a thousand tons of concrete and steel rebar, 30 to 50 feet across and anywhere from 6 to 30 feet deep. Shafts are sometimes driven down farther to help anchor it.

Mountain tops must be blasted to create a level area of at least 3 acres. The platform is critical to stabilizing the immense weight of the turbine assembly. How much do wind turbines weigh? Taller wind turbines also provide the additional clearance needed for longer blades that increase energy capture per turbine. Recent NREL analysis assessed how increased hub heights could impact key indicators of wind energy viability across the nation.

Research looked at factors of wind speed, capacity factor, and LCOE, as well as incremental costs that could be incurred for increases in turbine hub height. Difference in mean annual wind speed m above ground level minus 80 m. The analysis indicated that there are many areas that could warrant the pursuit of technology enabling higher hub heights.

Favorable sites for wind turbines include the tops of smooth, rounded hills; open plains and water; and mountain gaps that funnel and intensify wind. Average wind speed at 80 meters Average wind speed at meters Source: U. Source: U. In , 40 states had utility-scale wind power projects, with the most generation in Texas, Iowa, Oklahoma, California, and Kansas.
