FRANKFURT/BERLIN, June 23 (Reuters) - Siemens Energy (ENR1n.DE) warned on Friday that the impact of quality problems at its Siemens Gamesa wind turbine business would be felt for years and were not yet quantifiable, sending its shares tumbling by nearly a third.
Finance chief Maria Ferraro earlier told analysts that the majority of the hit would be over the next five years.
Issues at Siemens Gamesa have been a drag on the parent for a long time, prompting Siemens Energy to take full control of the business after only partially owning it for several years.
The discovery of faulty components at Siemens Gamesa in January had already caused a charge of nearly half a billion euros.
At the same time, he said he did not believe that the full takeover of Siemens Gamesa had been a mistake.
