Falmouth Wind Turbine Gear Boxes

"Vestas 1.65 kW turbines have had an "excessive mortality"

November 7, 2014

There are three Vestas V-82 type 1.65 megwatt turbines in Falmouth

Here is a quote about gear box failures :

"At Vestas, poor gearbox and bearing quality is showing up in larger models, the 1.65 MW, 1.75 MW and NM 2 MW, confirms the company's Tom Pedersen, director for northern Europe. The problems are limited to particular gearbox types, he says. Pedersen declines to be specific about how many turbines are affected and which gearbox makes he is referring to, explaining that Vestas has no statistics over gearbox usage and that the company is currently negotiating with the suppliers."

"Vestas retrofits"

"He says that gearboxes on Vestas 1.65 kW turbines have had an "excessive mortality," but that a "statistical excessive mortality" has not been seen on the 1.75 kW turbines. He declines to name the total cost of retrofitting the gearboxes and bearings on Vestas' larger turbine models. "It is a sum that is visible," he says.

Note # Portsmouth , Rhode Island High School is tearing down its turbine after a gear box failure two years ago. The gear box failed after only two years.

Otis Air Base has a Furlander 1.5 megawatt turbine installed in 2009 having a gear box problem.

Princeton and Templeton Massachusetts have had gear box failures in their turbines.

The Falmouth wind turbines are gear box driven wind turbines. Falmouth Wind 1 was built in 2005 and is a take off of the NEG Micon's 1.65 MW wind turbine. NEG Micon wind company was brought to its knees by gear box failures . Vestas bought the NEG Micon's 1.65 MW wind turbine today it is called the Vestas 1.65 MW turbine

Gear boxes have a general life of three to five years.
