No, Wind Capacity Factors Are Not 50 Percent in Minnesota, And That’s Very Important

Renewable energy advocates in Minnesota often claim that capacity factors for wind, the percentage of electricity generated by a power plant compared to its theoretical output, are sky high in Minnesota, exceeding the 50 percent threshold. Data from the Lawrence Berkeley National Labs show this claim is completely false. As you can see on the map below, there is not a single wind facility in Minnesota that operates above a 50 percent capacity factor.  The results don't get much better as we lower our standards, either. The U.S. Energy Information Administration shows the state-wide capacity factor for wind was only 35.9 percent in...

Minnesota’s Third-Largest Wind Farm is Already Losing Steam: Output Falls 14 percent from 2014 Highs

According the National Renewable Energy Laboratory, wind turbines have operational lifetimes of 20 years, but it appears Xcel Energy's Nobles wind project, the third-largest wind farm in Minnesota, is losing steam after just eight. The graph below was produced using data from the U.S. Energy Information Administration plant-level data. It shows the electricity generation of the Nobles wind project, which became operational in 2010, through 2018. You'll notice that electricity generation peaked in 2014, and that generation was about 14 percent lower in 2018, compared to the 2014 production levels. It is important to take note of this decline in electricity production...
