News & in-depth analysis of wind energy technology, including wind turbines, turbine blades, drive trains, electricity transmission, smart grids and energy storage.
Vestas is dismantling its multi-rotor concept after a two-and-a-half-year testing and validation campaign, in which the Danish manufacturer observed many technical benefits from the four-turbine prototype including a 1.5% power gain.
Vestas has opened its blade production facility in Ulyanovsk, according to the Russian Association of the Wind Industry (RAWI).
Blades equipped with 'bend-twist coupling', which enables them to react to varying wind speeds, will be tested by the Fraunhofer Institute for Wind Energy Systems (IWES).
INDIA: Siemens Gamesa Renewable Energy (SGRE) has officially opened a new research and development engineering centre in Karnataka, south-west India.
DENMARK: Researchers from the Technical University of Denmark (DTU) will look into the best ways of mixing fibreglass and carbon fibre into a new hybrid material to be used in wind turbine blades.
INDIA: The first 1.2GW wind-solar hybrid tender received bids for only 1.05GW of capacity from two participants.
INDIA: Turbine manufacturer Inox Wind will launch a 3MW turbine in India using a low-wind design from US firm AMSC.
UK: The new chairman of electromagnetic engineers GreenSpur Renewables believes the company's plans for an up-to 10MW generator could disrupt manufacturers' preference for rare-earth elements (REEs).
A German consortium has developed, tested and validated a self-aligning, lightweight, four-legged semi-submersible floating-platform concept that integrates the turbine tower. Eize de Vries highlights the technological innovations.
As demand for rare-earth elements pushes up prices, Windpower Monthly looks at how the wind industry is applying the lessons learned from the last price hike in 2011.
WORLDWIDE: Windpower Monthly's annual review of the industry's movers and shakers finds plenty of analysts showing what needs to be done, but few policymakers making it happen.
GERMANY: High-torque gearbox development, the mystery of the missing ministers, the death-knell sounds for pure-play OEMs, and the clout of the oil companies -- the Windpower Monthly team reflects on the news, product announcements and debates from the industry's biggest event.
GERMANY: A German consultancy promises to make wind power even greener. Eize de Vries talks to company founder Jörg Spitzner about Blancair, its innovative wind-turbine concept unveiled to an invited audience at WindEnergy Hamburg.
