Michigan Blade Failure

Mi_blade_break1_thumb Another turbine failure has been reported at Michigan's Deerfield wind facility in Huron County. The Deerfield project includes a mix of Vestas V110 2MW and 2.2MW machines for a total installed capacity of 150 MW. Two blades on separate turbines broke in half in late 2016 when the project was in the process of being commissioned. There was “an anomaly in the manufacturing process that resulted in a cavity in the blade shell support structure where the blades broke,” Vestas told reNEWS. Fifty blades in the 72-turbine facility shared the same flaw. No information is available on the cause of this recent failure.

The project uses a combination of Vestas and GE model wind turbines. The news report did not cite the make or model of the burned turbine. The initial turbines (phase 1) were placed in service in 2003.

Lake Land College removes, disassembles damaged wind turbines

Lake Land College has removed two wind turbines after they suffered enough damage to render them inoperable. "The situation with the two 100 kW wind turbines is a snapshot of renewable energy in the United States in 2017," said Joseph Tillman, the division chair and Lake Land College's renewable energy instructor and coordinator. Wind is going to be around for a while, but other forms of renewable (energy) are gaining in use.
