As the wind power industry matures, greater focus is being placed on Leading-Edge Erosion (LEE) as technology advancements and growing data on losses point to potential performance gains.
LEE occurs when dirt, moisture, salt or bugs create cracks or cavities on the first blade edge in contact with the air. Such defects compromise the aerodynamics of the whole blade.
Historically, many operators have not invested heavily in LEE after comparing the gains...
In December, the Blauwind II consortium-- owned by Eneco, Diamond Generating Europe (100% subsidiary of Mitsubishi Corporation), Shell and Van Oord-- won the tender to build the 680 MW Borssele 3&4 offshore windfarm situated 22 km off the Dutch coast.Related Content: Europe’s new record offshore LCOE forecast at 40 euros/MWhCable layer demand to pick up in key European offshore wind marketsTender design, output gains key to DONG’s record-low Borssele 1&2 offshore...
Global wind installs drop 14% on slower growth in China
Global wind installations were 54.6 GW in 2016, some 14% lower than the record 63.6 GW installed in 2015, the Global Wind Energy Council (GWEC) said in its annual statistics report published February 10.
In China, the most active wind power market, annual wind installations fell from 30 GW in 2015 to 23 GW in 2016, driven by cuts to feed in...
Competition from solar and gas-fired power generation and the gradual removal of renewable energy subsidies have increased the importance of reducing onshore wind power costs and raising operations and maintenance [O&M] efficiency.Related Content: Turbine suppliers offer longer service contracts, cut O&M chargesDuke Energy estimates cost savings of up to 35% from shifting to in-house O&MImage: Image Caption: Competition has cut wind O&M prices and widened the range of services.

New York State approves first offshore project
The New York State government has approved Deepwater Wind's 90 MW South Fork offshore wind farm project, paving the way for the first offshore project in the state.
Governor Andrew M. Cuomo announced January 25 the Board of Trustees of the Long Island Power Authority (LIPA) approved a 20-year 'pay for performance' power purchase agreement (PPA) for the South Fork project.Related Content: Offshore investments soar in...
Expiring feed in tariffs (FiTs) are raising operators’ exposure to low wholesale prices and new competitive tenders will test developers’ ability to lower operations and maintenance (O&M) costs in project bids.
Germany's new EEG rules implemented January 1 impose a competitive auction process for all future onshore wind contracts, requiring developers to bid against each other to receive a tariff.Related Content: German wind auctions hike power market risk for repowering projectsImage: Image Caption: Wind operators...
