Wind Talk: GE discusses PowerUp, a way to increase wind farm output by up to 5%

I’m Steven Bushong, assistant editor at Windpower Engineering & Development magazine. Welcome to another edition of Wind Talk, our podcast series that gives you the opportunity to hear from the industry’s newsmakers in their own words. In this edition, we hear from Jeff Wiener, Global Sales Leader for GE Wind Services, which is part of

GE expands Brazil wind turbine production facility

GE has announced the expansion of its Campinas, São Paulo, manufacturing facility and the creation of 35 new skilled jobs. Co-located with Brazilian machinery manufacturer and GE Group subsidiary GEVISA, the facility will produce nacelles for GE’s 1.7-100 and 1.85-82.5 wind turbines. The machine head is a primary component of a wind turbine and houses

The laser-cladding process (at work on a truck axel), can repair wind-turbine components, such as damaged or worn shafts. The process provides a metallurgical bond that fuses to the shaft surface so well it performs like new.

Laser cladding to make worn main shafts like new

A laser-cladding process developed by Caterpillar Inc. to repair wear and damage to large axels on mining trucks is applicable to worn or damaged main shafts of wind turbines. At a recent O&M Summit, Kristin Schipull, a metallurgist with Caterpillar (www.cat.com), showed how the process works and reported that repaired axels match the performance of

Nordex adjusts structures to local US market situation

Nordex SE announced today that the company will cease nacelle production at its Jonesboro, Arkansas facility after it completes the orders in its current pipeline. The decision was driven by the wind industry’s global overcapacity and the continued uncertainty and instability of the US market. The decision will not impact the current year’s business performance,

GE Power Conversion helps to build the future of wind power efficiency

Wind turbine developers will soon have open access to a £50 million testing facility in the U.K. based on unique and leading-edge technology. The state-of-the-art facility has been specifically designed for full-scale testing of large nacelles. GE’s Power Conversion lets them develop and build the next generation of wind turbines that will be increasingly efficient,

One of the world’s most advanced wind turbine test facilities supplied by GE Power Conversion

GE’s Power Conversion business has signed a turnkey contract with the Lindoe Offshore Renewables Center (LORC), a Danish center for testing renewable energy technology, for the construction, commissioning, and handover of one of the world’s most advanced facilities to test wind turbine nacelles with an output power of up to 10 MW. The Lindoe Nacelle

GE’s Energy Learning Center

Wind tech program good for college credits

Citing the need to recruit and train a larger, educated workforce to support the global expansion of renewable energy, GE and Excelsior College announced that company employees can receive nearly 50 college credits for completing the company’s intensive renewable-energy services training program. To earn GE’s Lead Certification Standard, technicians must complete more than 500 hours

Behind nacelle doors

Mike Rowe produces the engaging TV show “Dirty Jobs” rightfully named for the vile work he takes on. Rowe bravely spends the day doing the dangerous to the disgusting, from removing snakes from ponds to cleaning sewers, all for our entertainment. One not-so-disgusting but eye-opening job had him spend a day as a wind turbine

Wind Measurement Systems 101

Wind measurement systems: Measuring wind speed and direction is now done at least three ways: mechanically (cup anemometer with a vane), with ultrasonics, or with laser-based devices. There are variations to each. Mechanical sensors, for instance, use moving parts and can connect to data recording devices. The anemometer uses spinning cups for wind speed and

Bearings 101

Turbines use a wide variety of bearings. Large ones include huge 2-m diameter main-shaft bearings with two opposing rows of cylindrical rollers to handle enormous thrust and radial loads. These support the shaft that holds the hub and rotor. Slew bearings mount between nacelles and towers to let nacelles rotate as needed. These can have
