Gamesa has completed the installation of the first prototype of its G128-5.0MW onshore turbine at its research and development facility in Alaiz, Spain. The end of the assembly process triggers the start of the process of certifying the new turbine, slated for completion during Q4 2014. Type certification endorses the platform’s industrialization and marketing.
The task of assembling the G128-5.0 MW was facilitated by the use of the latest turbine design and manufacturing technology, and by overcoming the logistics challenge of having to ship the parts from various parts of Spain where they were made: the nacelle and hub from Tauste (Zaragoza); the powertrain from Lerma (Burgos); the generator from Reinosa (Cantabria) and the converters from Coslada (Madrid).
A single G128-5.0 MW turbine will generate enough power in one year to supply some 5,000 households. Two turbines will be sufficient to power a town the size of Tudela.
The plan is to install these turbines for the first time in a commercial wind farm in Salo (Finland), where the company will supply three units of the G128-5.0 MW low-temperature model to TuuliWatti this year. Gamesa will operate and maintain this facility for 10 years.
The G128-5.0 MW wind turbine prototype has a rotor diameter of 128m and a total height of 184m. The turbine is notably lightweight, which reduces the cost of related wind farm civil engineering work. Its modular and redundant design ensures reliability and maximizes energy output, thereby lowering the cost of energy while complying with the most stringent grid-connection codes and environmental standards.
The G128-5.0 MW turbine evolves from the 4.5 MW platform and caters to the most complex wind farm developments in terms of competitiveness and cost of energy.
