Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

DoDo, from Alpha Ventus we're not looking at the difference in inter-annual variation, but performance against real wind. Alpha Ventus has great performance, better than expected. What's more important is the cost of that high performance. Alpha Ventus was built as a test field for the offshore generation of turbines, and that's its value.

The Wartungskosten (O&M costs) are indeed high to create such performance, but again, Alpha Ventus is a test field. Each manufacturer has only six turbines, so optimizing costs is not even in question. But as a test bed for high capacity commercial installations, it is a completely successful operation. Remember, this is the first of the deep water, far afield offshore projects.

As for when German first round projects will be online, the delays to date rest primarily on the shoulders of the grid operator, TenneT, and its converter station suppliers. To make lemonade out of lemons, this delay has given manufacturers and logistics suppliers (vessels) more time to optimize procedure.

The German government is actually responsible for the unlikelihood it will meet its 2020 installation target. Also remember that unlike every other EU country, Germany opted to avoid all near shore controversy, by beginning in deep water at great distance.
