Der Spiegel is reporting that all those wind farms in Germany are having an unfortunate effect on the stability of the electricity grid and that manufacturing industry is counting the cost.
It was 3 a.m. on a Wednesday when the machines suddenly ground to a halt at Hydro Aluminium in Hamburg. The rolling mill's highly sensitive monitor stopped production so abruptly that the aluminum belts snagged. They hit the machines and destroyed a piece of the mill. The reason: The voltage off the electricity grid weakened for just a millisecond.
Workers had to free half-finished aluminum rolls from the machines, and several hours passed before they could be restarted. The damage to the machines cost some €10,000 ($12,300).
A problem that is no doubt coming to an employer near you soon.
