Twelve turbines stand in formation about 45 kilometres north of Borkum, far enough from the island that holidaymakers on the beach see only horizon. Out here, in 30 metres of North Sea, Germany ran an experiment. The country had spent decades arguing about how its post-nuclear, post-coal grid should look — and what it would actually take to plant industrial machinery in salt water and keep it spinning. The first answer was alpha ventus. The name is intentionally lowercase, the alpha small and unassuming, as if to say: this is just the beginning.

Contracts for turbines and a subsea cable followed in 2007, and only in July 2008 did anyone actually start building the substation. That timeline — nine years from idea to first steel in the water...

Six of the turbines are Adwen AD 5-116 machines, descended from the Multibrid M5000, planted on tripod foundations dropped by the jack-up barge Odin. The other six are REpower 5M turbines, bolted to OWEC jacket quattropods se...

In 2011 alpha ventus posted a capacity factor of 50.8 percent — meaning the turbines, averaged across the year, produced just over half of what they could theoretically deliver running full bore every hour. That was the highest figure for any European offshore farm at the time. I...

Alpha Ventus Offshore Wind Farm: Built to Be Studied, Built to Retire

Photo credit Busbahnhof, CC BY-SA 3.0. From the start alpha ventus was less a power plant than a national instrument. The Federal Ministry for Environment funded a stack of research projects sitting on top of every cable and bolt: wake measurements, induction-zone studies, ecological monitoring of harbour porpoises an...
