It&#8217;s a particularly difficult one to refute in the press, as by the time you&#8217;ve tried to explain the difference between capacity factor and operation time, you&#8217;ve lost them.

It&#8217;s on a marginal site, one that probably wouldn&#8217;t be developed by a commercial entity.

Our turbine&#8217;s a bit more cranky than most, and I have a suspicion that our metering system is dropping some production, but even so, 63% is way more than the claimed 25%.
