The mysterious met tower

What can be 198 feet tall but be overlooked as easily as the infamous missing 10-millimeter socket? While meteorological (met) towers are a critical part...

Boosting operating efficiency

The cost of maintenance in the wind-turbine industry is escalating: A report from GlobalData estimates that the cost of turbine maintenance will rise to...

Tackling turbine security

One wind turbine can create 18 full-time jobs in the U.S., and so even detractors are having a hard time ignoring wind power’s momentum....

Protecting critical equipment

Tribology is the science of interacting surfaces in relative motion. Basically, it studies friction, wear, and lubrication — three phenomena linked to surface degradation...

Skill is just the beginning

Building a professional workforce is an essential, but often overlooked, component of wind-energy development. Thanks to private landowners in the heartland, wind-energy development is now...

Competency-based training

Creating an educated workforce skilled to meet the demands of a changing economy is the focus at Kalamazoo Valley Community College’s Groves Campus. Originally...

Rising Costs of Wind O&M and the Importance of the Human Factor

As fleets age and the cost of wind-energy O&M rises, wind-farm owners and operators look far and wide for ways to achieve efficiency. In...

Cheaper Wind Equals More Wind

American wind energy continues to power forward to reach new heights. Today, it powers more U.S. families and businesses than ever before — the...

The World of Turbine Bearings

The operational challenges for wind turbines can be daunting, whether related to increased turbine power and size, extreme weather conditions, heavy loads, and/or remote...

The Business Value of Digitalization

Digitalization may mean something different depending on who you are talking to in the wind industry. For some, digitalization is about getting ahead of...

Verifying remote sensing devices

Edition 2 of the International Electrotechnical Commissions (IEC) 61400-12-1 standard for power performance measurements was released in early 2017. This new standard codified the...

Priming the grid for green

Connecting the East Coast’s first offshore wind development (Block Island Wind Farm) to the electric grid involved installing new overhead and underground lines onshore,...

Improving the friction power of gears and bearings

A machine that runs endlessly without any wear and frictional losses — who wouldn’t dream of that? Unfortunately, such a machine does not exist...

Small component, big reliability

When extremely high-speed data communication is a necessity in a wind turbine, one solution is a fiber optic rotary joint (FORJ). While not a new...

Extending the life of wind-turbine components

With the increasing demand for carbon-free renewable energy, more companies are turning to wind power as a source for their energy needs. Although this...

Monitoring wind in cold climates

Wind-farm operators in cold-weather climates such as Canada, Sweden, and parts of the United States are confronted with unique operating challenges. When faced with...

Changing Turbine Gearbox Oil

Wind turbines remain a significant component of alternative electricity generation. The traditional design of such turbines includes a rotor, a generator, and a gearbox,...

Torque loading: Standards have limits

(Editor’s note: This article on torque loading is presented in two parts. Part 1 on how drivetrain components are important in analyzing component performance...

The Role Of Lidar In Offshore Wind Measurement

The advanced wind-measurement capabilities of Lidar have unleashed tremendous opportunities for the offshore wind industry. After years of successful validation campaigns, offshore professionals are...
