The 1.5MW Wind Turbines are a series of wind turbines manufactured by the General Electric (GE) Company. Introduced in 1996, each turbine consists of three fibreglass blades attached to a horizontal hub and a main shaft that converts kinetic energy from the wind into electrical energy. As of December 2010, there are more than 13,000 units in 19 countries worldwide and the wind-turbine technology provides a maximum of 1.5-megawatts of electricity with minimal noise and greenhouse-gas emissions.

Types and Dimensions

The GE 1.5MW Wind Turbines include three models: the 1.5se, the 1.5sle (called the "workhorse" by the company), and the 1.5xle, which uses the same platform as the 1.5sle model but captures more wind energy due to a greater swept area. The rotor diameters are 231 feet for the 1.5se, 253-feet for the 1.5sle, and 271-feet for the 1.5xle model. The hub heights range from approximately 212 to 262 feet.

Temperatures and Wind Speed

The GE 1.5MW Wind Turbines include an operating temperature from -22 to 104 degrees Fahrenheit and a survival temperature as low as -40 degrees Fahrenheit to as high as 50 degrees Celsius. The cut-in wind speeds for the turbines are approximately eight mph and the cut-out wind speeds range from 45 to 55mph.

Operating Specifications

All three 1.5MW wind turbines include an electrical pitch and yaw system that controls the angle of the blades and the direction of the turbine to capture the maximum amount of wind-energy. Each model has a rated capacity of 1,500kW with an electrical interface with a frequency of 50-60Hz and a voltage of 690-\ volts. As of December 2010, two wind-turbine upgrades include the WindBOOST Control System that provides the capability to remotely control the turbines, and the Reinforced Tower, which provides a reinforced-tower design that allows wind farms to be located in areas with seismic activity.
