News and Analysis

Outdated software leaves developers 'vulnerable' to cyber attacks

Renewable energy developers are "very unprepared" for cyber security attacks, a senior analyst for underwriter GCube told Windpower Monthly, after an attack victim was named in government documents.

Goldwind's world-first laser control system approved

DNV GL has approved Chinese manufacturer Goldwind's lidar-assisted control system for wind turbines -- the first time the certification body has verified a laser-aided system for turbine control.

Global offshore wind fleet to grow 15-fold by 2040

Rapid technological improvements and falling costs could help drive an exponential increase of the global offshore wind fleet by 2040, but additional investment and the sector unlocking new revenue streams could prompt a 25-fold growth.

Senvion collapse could contribute to 'modest' turbine price gains

New analysis predicts onshore wind turbine prices could see a "modest" increase in the early part of the next decade, in part due to the collapse of Senvion.

Up for grabs: a queue forms for Senvion's servicing deals

Following the loss of the servicing contract at the 203MW Trianel Borkum Windpark II site in Germany, Windpower Monthly takes a look at where other deals could be made.

Viewpoint: How blockage effects skew energy-yield forecasts

After correcting some key methods behind the original estimates, major offshore wind developer ├śrsted recently made news with a downward revision of the expected internal rate of return for seven of its offshore wind projects.

Horns Rev 1, 2, 3: three generations of turbine output analysed

The three projects that make up the Horns Rev offshore-wind hub off Denmark's west coast perfectly illustrate how the sector developed over the last two decades. Windpower Monthly dissects the performance data to see if bigger really is better.

SGRE brings leading-edge protection as retrofit

Siemens Gamesa Renewable Energy's (SGRE) solution to prevent leading-edge erosion combines a hardware upgrade with simulation software. Already incorporated into the blades for its latest offshore platforms, the company is fitting it to hundreds of operating onshore and offshore wind turbines.

The innovations that are changing the face of the O&M market

As turbines grow taller and blades get longer, keeping them in working order throws up new challenges. We look at the trends in the service sector and pick out some innovative new solutions.

Devising O&M strategies for floating offshore

Should repair and replacement of major components on floating turbines be carried out at the project location, or in the still waters of port after tugging the unit home?
