The G114 turbine, with unit capacity of 2.0 MW, features a a 114-metre diameter new rotor with a swept area of 10,207 m² that increases a 38-percent in swept area plus a 20-percent 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), though we expect the 120m to be the most popular.
Low power density and proven technology
The new turbine promises to be a benchmark in the industry thanks to its low 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.
The Gamesa G114-2.0 MW completes one of the most versatile, proven and validated turbine systems on the market, the G9X-2.0 MW. By way of example, in the first year of the G97-2.0 MW turbine’s launch, Gamesa sold a total of 358 MW of the machine 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 (80metres, 87 metres, 90 metres, 97 metres and 114 metres in diameter) makes it ideal for any type of site, with availability levels exceeding 98%.
India, areas of China, Brazil and low-wind sites in Europe and the United States
"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.
The turbine’s characteristics make it ideal for growth markets, including India, China provinces closed to large consumption areas (Beijing and Shanghai), Brazil and low-wind sites in Europe and the United States.
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.
