In June, Siemens Gamesa announced that the problems with the quality of the company’s wind turbines were greater than previously thought. So much so that the turbine manufacturer’s owner, Siemens Energy, not only tanked revenue guidance for the year, but did so with a statement that the cost of repairing the failure rates would ”likely exceed EUR 1bn”.

An estimate that was not only bleak - but without an upper limit, it also left a lot of room for speculation. In the worst case scenario, the costs could amount to as much as EUR 5bn, according to the investment bank USB, for example.

However, it won’t be that bad. At least that is the assessment of a source with knowledge of the subject, Reuters reports. The person estimates that the bill will end up at less than EUR 2bn and believes that it is plausible that the repair and replacement work on up to 1,000 problem-affected turbines would cost between EUR 1.5-1.7bn.

The turbine manufacturer will communicate news about the extent of the problems in connection with the presentation of the quarterly report on Monday, August 7. According to Reuters sources, the advisory committee set up by Siemens Energy to investigate the extent and causes of the problem will be presented with the preliminary results of the investigations on Friday.
