OK, now i understand your point. Though it involves completely changing the payment structure (or adding another type of tariff), and also the control systems of the turbines.

1.  A turbine, or a windplant, can be de-tuned to operate less than optimal normal efficiency, in effect spilling wind. If it's already operating at less efficiency, it can be ramped up again.

2.  A turbine can not be operated above it's design efficiency (power curve) but for short bursts. (a 2 MW generator can peak at say 2.2, 2.3.) the potential gust loads become too high.

3. If a turbine is operating at peak efficiency, it can only be ramped up if it's operating below peak power AND the wind also ramps up. If the blades are detuned, OK.

4.  Detuning the blades in effect means new and more complicated control algorithms, as well as potentially exceeding existing design parameters. That might even entail new load calcs, and thus new certifications.

5. So at present, theoretically it's possible to some limited degree, but involves another generation of design effort.

6.  Perhaps more possible are the addition of various storage technologies together with a more varied renewable grid, which may include load balancing technologies (smart grid).

7.  Perhaps more important, none of this actually matters in the real world, until a national grid has far above 20% incursion from wind. Unless you are trying to get your nukes permitted for another round, and your coal buddies some cash.

8.  If the FDP (or anyone) was serious about real world energy, we would already be seeing a crash program of building insulation. But we're not, so what does that tell you.  They're bitching like spurned whores, over 0.4% of costs from one metric only, which has nothing to do with the whole picture.

9.  Tempest in Teapot.  reminds me of the vehement attacks against wind by the transmission operators about 8-6 years ago, accompanied by draconian attempts at regulation. scared that we were going to crash the grids with our uncontrollable shit.  now all the parent companies are investing in humungous wind projects. same in nord amurka.  they gave all manner of technological reasons why we couldn't penetrate more than a few percent.  no one really argues 20% anymore. unless it's your wallet. i wasn't all that upset when the automobile decimated the horse and buggy blacksmith trade, though i did think the exhausts stunk and were poison.

10.  when the FDP comes up with authoritative numbers about how much it costs to have inefficiencies throughout the grid (far larger than this mosquito prick), we'll be on another planet.

11. hey guido, shut the fuggup.  (my boy westerwelle.)
