Sierra Wind Platform

Next-generation 3 MW onshore wind turbine

Built off GE’s 2 MW platform, the Sierra platform is designed specifically for North America to deliver high-capacity factor with balance of plant simplicity, and reliable, bankable performance.

Technology

New yaw system with hydraulic braking

GE’s patented Advanced Loads Control system

Low noise trailing edge & noise reduced operation

Easier Hub Entry

3 hub hatches to access hub internals

Direct internal access to fastening & pitch bearing hardware

Low torque bearing to reduce mean load

Electrical System

Simplified design to improve accessibility

Doubly-fed induction generator with power converter

Grid voltage support to quickly supply/draw reactive power

Down Tower Assembly

Streamlined for installation & commissioning

External pad mounted transformer for reduced losses

Converter uses a MarkVIe controller to provide dynamic reactive power

Sierra platform: The future of onshore wind

Capture even more wind energy while improving economics

Tested
& validated

Built on the legacy of GE’s bestselling 2 MW platform, which recently surpassed 30 GW of installed base globally.

High capacity
factor turbines

High-capacity factor turbines with reduced pads per site (50% decrease in pads per 100 MW).

Two-piece
blades

The 68.7m two-piece blades enable improved logistics, installation and O&M.

Building on bestselling technology

Playing on the successes of the 2 MW technology, the Sierra features a 140-meter rotor and is offered with a variety of hub heights, including a <500’ option. The Sierra platform includes GE’s revolutionary two-piece blade, designed to improve logistics and installation.
