In the windiest on land locations in the US, a wind farm could have a 40% capacity factor or produce 40% of its maximum output. That does NOT mean that it is producing power 40% of the time. In fact, many wind farms are producing some power 85% or more of the hours in a year. Many things impact capacity factors of all plants--economics, fuel, planned maintenance outages, unplanned maintenance outages. As a rule of thumb, a baseload gas plant (designed to run nearly all the time near maximum output) will produce about 3 times more power per megawatt of capacity than a megawatt of wind. So the 340 megawatts of gas capacity built in the US during the first quarter, if it is designed to be baseload and not peaking power, will produce about an amount of electricity equal to or a bit greater than the approximately 900 megawatts of wind built in the US during the first quarter.John Hangerhttps://www.blogger.com/profile/06565915866938789295noreply@blogger.comtag:blogger.com,1999:blog-4664957094233317169.post-9261675587347046252013-04-09T09:50:15.653-04:002013-04-09T09:50:15.653-04:00When we're talking about capacity ratings for ...When we're talking about capacity ratings for renewables, is that assuming what their output would be if they were subjected to optimal conditions 24/7/365? Or does that factor in the inevitable periods of lower productivity? <br /><br />Michael Knapphttps://www.blogger.com/profile/09678133434815647612noreply@blogger.com
