Wind Power Expansion and Output in Texas

Wind capacity was expected to increase in Texas in early 2014 due to transmission line debottlenecking.  Texas is the largest producer of wind power in the US and it continues to grow.  But wind output is unpredictable, especially in winter away from coastal areas.  

Here are the 1 hour generation profiles of wind output in Texas so far this year.  Note that the wind didn't blow for several (cold) days in mid-February.

Wind output in Texas did set a new record for January, but it is down substantially in February.  The month ends tonight, and generation is averaging about 900MW lower than last year.  Severe cold, which we have seen this year, tends to be inversely correlated with wind, which probably explains the decline.
