Gamesa says certification body DNV-GL has certified its G128-5.0 MW offshore wind prototype.
According to Gamesa, the wind turbine – which has a rotor diameter of 128 meters and a total height of 154 meters – has generated more than 6,000 MWh into the grid since it began operating in summer 2013. Additionally, Gamesa notes that the G128 turbine is lightweight, therefore reducing the cost of related wind farm civil engineering work.
Gamesa claims such characteristics make the platform more robust and reliable. For example, the prototype registered an availability reading in January of 97%. In November 2013, Gamesa notes the offshore prototype produced the most electricity ever generated by a single turbine in Spain in one day: 118.05 MWh.
