2002-02-01 00:00:00 |  |  |  |  |  |  |  |  | Monthly Totals from columns below: |  |  |  |  |  |  |  |  |  |  |  | The overall result for the whole month
 |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  | Note that while individual time period differences can range from a few to over 100,000,
 |  |  |  |  |  |  |  |  |  |  |  | Based on Wind Speed |  |  |  | Based on Turb Data |  |  |  |  | the month as a whole is very close.  There may be problems with the time stamp or turbine figures.
