Gamesa launches “milestone” low-wind turbine

Wind energy leaders announce benchmark product for the wind power industry

"Benchmark" turbine could be adapted to any type of site, believes Gamesa

Global wind technology provider, Gamesa has launched of a new wind turbine designed to achieve maximum returns from low-wind sites.

The announcement was made during European wind association, EWEA’s 2012 conference in Copenhagen.

The G114 turbine, with unit capacity of 2.0 MW, features a 114m diameter new rotor with a swept area of 10,207 m² that increases a 38 per cent in swept area plus a 20 per cent increase in annual energy output compared with the G97-2.0 MW turbine.

The new blade, spanning 55.5 metres with aerodynamic features developed using state-of-the-art technologies, also enables maximum energy production with reduced noise output levels. The machine offers a range of tower height options (from 93m to 140m or higher, depending on the target location). However, the company expects the 120m to be the most popular.

The turbine provides a “benchmark” for the industry due to its power density, the lowest on the market for its segment, and will help the company meet one of its targets for significantly reducing Cost of Energy (Coe) among Gamesa's Class III products, Gamesa said in a statement.

In the first year of the G97-2.0 MW turbine's launch, Gamesa sold 358 MW units to customers on four continents. This turbine has evolved to become Gamesa's new Class II product in the 2.0 MW market beginning in 2013.

The combination of a turbine with unit capacity of 2.0 MW and a selection of five different rotors – 80m, 87m, 90m, 97m and 114m in diameter – could make it ideal of any type of site, believes Gamesa.

"Our customers need to make the best use of the energy potential offered by low-wind sites, and thus require a turbine that can get maximum energy with a low investment cost. The G114-2.0 MW turbine is based on the same technology used in the G97-2.0 MW, but with some elements optimized and reinforced", said Juan Diego Diaz, Gamesa's Marketing Director.

Gamesa will begin manufacturing initial prototypes of the G114-2.0 MW in the third quarter of 2013, with the first turbines supply to begin at the end of the same year. From 2014, the company will start manufacturing market-ready series in all of the regions in which it has a manufacturing presence.
