The most widely sold wind turbine in the megawatt-class for the global wind power industry has reached a major milestone. GE Energy announced today (September 30) that its 2,500th 1.5-megawatt machine has been installed as part of ENEL's Littigheddu project in Sardinia, Italy.

Using 36 of the GE 1.5-megawatt wind turbines, it is ENEL's largest wind project and one of the largest in Italy.

In conjunction with this landmark installation, GE also cited the long, continuing evolution of its 1.5-megawatt wind turbine technology.

The first 1.5-megawatt wind turbine was installed in April of 1996 in Germany, and quickly developed into the workhorse of the GE Energy wind turbine fleet worldwide.

Over the years, an ongoing improvement program has integrated valuable lessons learned and knowledge gathered from long-term plant operation and customer feedback.

Currently new research and development efforts are being implemented to further enhance the 1.5-megawatt design, including efforts to provide greater efficiency in lower wind regimes.

"Our 1.5-megawatt wind turbine has been proven in nearly every wind regime, terrain and climate worldwide," said Steve Zwolinski, president of GE Energy's wind operations.

"As we celebrate this milestone, we also continue to invest in technology improvements that will build upon the vast experience base of our installed fleet and will result in even higher levels of wind turbine reliability and efficiency."

To support further R&D efforts for its wind energy technologies, over the past two and a half years GE Energy has increased its wind engineering workforce fourfold, and has utilized synergies with other GE businesses to incorporate best practices, lessons learned and Six Sigma quality processes into its wind turbine development efforts.

In recent months, the company has invested more than $10 million in R&D enhancements for the 1.5-megawatt wind turbine, as well as other wind technologies.

Recent enhancements/new features of the 1.5-megawatt technology include:

Variable rotor diameters that can be optimized for every category of wind application to increase energy yields and reduce energy generation costs.
Innovations in power electronics, including WindVAR (Wind Volt Amp Reactive Technology).
Along with the previously introduced Low Voltage Ride-Thru (LVRT) capability, this new technology will further increase the grid stability of the 1.5-megawatt turbine.
Cold Weather Extreme package, which enables operation of the wind turbine in temperatures as low as -30 degrees C and guarantees a survival temperature of -40 degrees C.
A modular tower that enables 1.5-megawatt wind turbines to be adapted to hub heights ranging from 61 to 100 meters, providing customers with the flexibility to meet local regulations.

In addition to its 1.5-megawatt technology, GE Energy's wind turbine portfolio also includes the 2.x series, which is designed to accommodate a wide range of wind sites and conditions; and the 3.6-megawatt wind turbine, the first wind turbine of its size class to be deployed at sea.
