Wind-energy experts say incidents such as the splintering of two blades and cracks in five others produced at Gamesa's Cambria Township factory are rare. The American Wind Energy Association views the problem as a fluke, an anomaly that turned up in a time-proven industry involving a highly respected company. "We haven't heard of anything like this before. There have been thousands of blades installed, and this is a first," said Christine Real-de-Azua, spokeswoman for the wind energy national trade association, based in Washington, D.C. "Offhand, this doesn't seem like a big issue. We haven't heard of any other problems."

The Allegheny Ridge Wind Farm's phase one startup has been put on hold because some of Gamesa's locally made blades are chipping apart. Gamesa officials, who met with Portage and Washington township officials Wednesday for the go-ahead on a second phase, said they found issues with seven blades after realizing two of them splintered on the towers. They had hoped to have the first phase online by the end of the month. "The structure of the blade was intact in most places ... it somehow split open and fell," said Alberto Gros Isla, the plant's manager. It wasn't the blades that fell; rather, it was a "thin fiberglass skin" that coated them, he said. One piece stretched the length of the 147-foot-blade, and another was at least 20 feet long, Gros Isla said.
