Gamesa Certifies Its 5MW Wind Turbine

Gamesa has secured type certification for its first offshore wind turbine, the G128-5.0 MW Offshore, from DNV-GL, an accredited independent body.

This milestone completes the process of certifying the company’s first offshore product – in less than seven months – and constitutes an endorsement for the platform’s technology that in turn bolsters the marketing and industrialisation processes.

The G128-5.0 MW wind turbine prototype, the first offshore model in the 5.0 MW platform, has a rotor diameter of 128m and a total height of 154m. The turbine is notably lightweight, which reduces the cost of related wind farm civil engineering work. The G128-5.0 MW Offshore is capable of generating enough power to supply 5,000 households a year. Since it began to generate electricity in the summer of 2013, the prototype has injected more than 6,000 MWh into the grid.

These characteristics, which make the platform more robust and reliable, facilitated an availability reading in January of 97%, no easy feat for a prototype still at the validation stage. In November 2013, the prototype beat another record, producing the most electricity ever generated by a single turbine in Spain in one day: 118.05 MWh.
