US wind giant designs turbine for Brazil

GE introduces turbine for BRIC country’s high-wind speed sites

The turbines are designed for high-wind sites in Brazil

A US energy firm has developed a turbine designed to meet wind conditions in Brazil. GE, North America’s leading wind turbine supplier, is introducing its new 1.85-82.5 wind turbine to the country, which is designed to work in high-wind sites.

The 1.85-82.5 wind turbine which is IEC-certified for higher wind speed sites or environments, is the latest evolution of GE’s wind turbine technology and builds upon the vast and diverse experience of GE’s installed fleet of 18,000 wind turbines worldwide. The new turbine offers an 8 per cent increase in annual energy production (AEP) at 9 m/s, which drives improved project economics for wind developers in higher wind regime sites.

GE’s proprietary advanced loads control allows siting of the 82.5m rotor in more aggressive wind regimes, combining drive train sensors and capabilities of the Mark Vle controller to individually pitch blades and improve load-handling performance. A sophisticated set of grid-friendly features will enable operators to meet stringent grid requirements in 60-hertz regions.

“With the introduction of the 1.85-82.5 wind turbine, we continue to advance our 1.5-megawatt class wind turbine product line, which has been proven in a wide range of wind regimes worldwide,” said Victor Abate, vice president of renewable energy at GE. “Focusing on performance, reliability, efficiency and multi-generational product evolution, the 1.85-82.5 is designed for Brazil’s growing wind energy requirements.”

GE technology already is well established in Brazil, with 300 GE wind turbines now installed in the country.
