Siemens Energy’s disclosure of quality issues in its newer wind turbine models has exposed broader challenges in a sector suffering from rushed development, soaring materials costs and a flawed market design.
Siemens Energy shocked the wind sector in late June when it warned of faulty components and possible design faults in its onshore wind turbines.
It said it could not yet quantify the cost, but anticipated the issues would take at least 1 billion euros ($1.1 billion) to fix. Company sources, speaking on condition of anonymity, have said the final bill could be even higher.
