Siemens Gamesa and Iberdrola have signed maintenance service contracts for a total of 1,928 MW across 69 of the energy group's wind farms in Spain and Portugal for a period of between three and five years. These include 1,963 wind turbines from the G4X (660 kW unit power), G5X (850 kW), G8/9X (2.0 MW), Siemens Gamesa 2.X (SG 2.1-114 and SG 2.6-114) and Siemens Gamesa 3.X (SG 3.4-132) platforms. With these new contracts, Siemens Gamesa consolidates its position as Iberdrola's main provider of operation and maintenance services in the region. These are new contracts and renewals. The maintenance of the wind farms included in these contracts requires the work of around 160 employees. The wind farm technicians are usually located in the rural areas where the wind farms are located, so wind farm maintenance supports local activity and employment.The maintenance work applied to these types of turbines, the oldest in Iberdrola's fleet, allows them to significantly maximise their level of efficiency, as well as extending their useful life in the medium and long term.
