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

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

What Measures Wind Speed? Wind Measurement 101

Wind speed 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

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

OEM completes assembly of 1,000th nacelle at Penn plant

Turbine OEM Gamesa Technology Corp. has announced the completion and shipment of its 1,000th nacelle manufactured at its Fairless Hills plant in southeastern Pennsylvania. The finished nacelle is among the 152 G90X-2.0 MW wind turbines comprising the 304-MW Blue Creek Wind Farm in Van Wert and Paulding counties in western Ohio. The project, which is

R&D lab considers superconducting for 15-MW wind turbine

The technology development arm of a large electrical firm says it has begun work on the first phase of a two-year, $3 million wind project from the U.S. Department of Energy. GE Global Research ( says it will begin work on a next-generation generator for wind turbines that could support applications in the 10 to

Cooling electronics in a hot nacelle

It’s no secret that wind-turbine capacity, particularly for offshore turbines, continues to grow each year with 6 to 10 MW on the horizon. Even with efficiency improvements, key power generation subsystems —including generators, power-conversion electronics and transformers—are challenged to manage ever increasing heat within limited nacelle space. In addition, even if incurred power losses are

New thinking in turbine design

A novel turbine design uses two rotors of equal diameter, one each at opposite ends of a nacelle, to capture wind at greater capacity factors than conventional designs can do, say developer Airgenesis LLC ( The developer says the rotors, offset from each other by 60°, will be turning at low speeds of 2.5 to
