Texas Wind Power Expansions

Improvements to the ERCOT power grid brought more Texas wind capacity online in January 2014.  But after an initial surge in wind power output in January, weather and other factors have reduced output relative to 2013 in Feb, Mar, and so far in Apr.  In fact output has closely tracked 2012.

Here are the hourly wind power profiles for each month, and the average output by month since 2012.  It highlights both the hourly variability and the wide range in aggregate output over time from wind.  (Output can range from 1,000 MW to 10,000 MW over a 24 hour period!)
