IS FENNER AN EXPERIMENT ~ IN MOTION?



FENNER TURBINE DOWN:

The largest Wind project east of the Mississippi .
Is Fenner just nothing more than experiment in motion?
Is Fenner nothing more than a test of wind pressure and wind torque?
A pressure too great for the concrete base to sustain for a ten year period.

Did the developers of Fenner's wind turbine system, actually pre - determined the wind turbine reaction forces in conjunction with the wind pressure forces on the towers, and the turbine blades themselves to withstand the overturning moments developed, that are being resisted by the soil or rock material that is, part of the anchorage resisting system, as required by New York’s Construction codes? One issue with wind turbines is that they actually try to unscrew them selves from the ground, due to wind pressure forces. The anchorage systems and subsurfaces are critical factors in wind turbine design.

Last December, a GE 1.5 megawatt turbine at the Fenner wind facility in Fenner, New York collapsed. An official report explaining the root cause of the collapse is still pending but news this week shed light on the situation. According to the article, "concrete core samples from the foundations preliminarily showed inconsistent aging and degradation".

Hank Sennott, director of corporate affairs and communications for Enel North America told the Madison County Courier "I don't know of any turbine foundation failures, but we were the first, so there is nothing to go back and research. This project was the largest built east of the Mississippi when we constructed it 10 years ago. There's no history for us to look at."
