The company has provided more than 132 gigawatts (GW) of wind turbines as of the end of April this year to all global regions: 108 GW of onshore wind and 22 GW of offshore wind.
The discovery of faulty components at Siemens Gamesa's onshore wind turbines had already caused a charge of nearly half a billion euros in January.
Siemens Gamesa has provided wind turbines to some of the biggest power companies and oil and gas majors worldwide.
Shares in European wind turbine producers Nordex (NDXG.DE) and Vestas (VWS.CO) also fell as confidence in the industry was shaken.
Many wind power developers have already seen delays in projects due to the availability of components and rising costs.
