Gamesa: first manufacturer to certify a wind turbine life extension programme

Gamesa has become the first wind turbine manufacturer to achieve certification for its useful life extension programme under the standard issued by independent certification body, DNV GL. This certification – awarded to the G47-660 kW life extension programme – again demonstrates the company’s technological leadership, underpinned by an extensive portfolio of products designed to reduce the cost of energy (CoE). The life extension programme consists of a series of structural upgrades and monitoring features which allow owners to lengthen the useful lives of their wind turbines from 20 to 30 years, with the highest guarantees of safety and availability. These 10 additional years of useful life lock in supplementary income and thereby enhance the wind farms’ profitability.

The certificate awarded by DNV GL was based on a detailed analysis of the design, specifications and calculations applied to the entire life of a Gamesa G47-660 kW wind turbine, from the year in which it is installed until year 30.

The ability to extend the useful life of a turbine is a key step in maximising efficiency and reducing costs in the global wind energy market. One of the greatest benefits of this programme for customers and operators is the reduction in the cost of energy associated with the product’s life cycle. The life extension programme constitutes a unique opportunity as it manages to generate a higher return on the wind farms with hardly any risk investment.

Gamesa will apply its life extension programme to 850 kW and 2.0 MW turbines and even to turbines made by other OEMs which are maintained by Gamesa.
