The rise and rise of the super-size wind farm
There is a steady rise in the number of very large new onshore wind farms being built annually, and in their operating capacity. Windpower Monthly examines the drivers behind today's super-sized projects.
WindTech: Master classes in offshore turbine design
Students on a wind engineering master's course worked together to develop an impressive 12.5MW offshore turbine. Eize de Vries spoke to them and one of the professors about what makes their design different from current offerings.
Europe's dismal year drags down global installation figures
The shift to competitive tendering in several of the main wind markets continues to have a negative effect on new installations, with Europe in particular feeling the squeeze last year. Windpower Monthly sifts through the provisional global figures for new build in 2018.
Testing lags behind blade development
As rotor blades get longer and lighter, more complex designs introduce potential errors during manufacturing, while testing and certification are too limited in their nature. The result can be expensive failures and downtime.
Why structural stability is key to life extension
When wind turbines approach the end of their design life, an assessment for lifetime extension determines whether a turbine is suitable for continued operation. Christian Schumacher and Florian Weber of certification body TÜV SÜD outline the process and how operators can prepare.
Snapshot: Shipping blades from China
This may look like an offshore sector picture, but it illustrates the global nature of the onshore suply chain: a German firm shipping Chinese made components to Spain on behalf of a Danish OEM.
WindEconomics: Wind and PV beat coal and gas in Australia
A report by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia compares the generating costs of all electricity-generating technologies currently in use, plus nuclear, not currently utilised in the country. The work was carried out in conjunction with the Australian Energy Market Operator.
Battle over US dominance heats up as GE retakes crown
GE inched ahead of Vestas for annual installations in 2018, but the Danish manufacturer supplied the single most-installed turbine in the US.
