The lines I shaded blue are typing errors that I fixed. These will account for the negative hours and the turbines with no data. The turbines that are showing hours but no production must be a result of a SCADA data acquisition problem. These entries I shaded in red. I started looking through the list in the April Log but I could not find any errors on our side, so you may have to base the lost production on what a particular turbines' neighbor produced or lost. Call me if you have any questions.

It appears that you may have some entries where the operator used the 12 hour clock instead of th 24 hour clock. There are many rows where a turbine is curtailed but the way the time is recorded makes it come out with zero production. Call me if you need help.

There are a few problems. Scanning through it it appears the site personnel entered some times backwards so there were a few negative durations with 0 kWh predicted productions. I also do not know what is causing the other 0 kWh productions (it might be low wind, or there might be some other problem). There was a 90.9% data recovery. The predicted production for the month was 45929604 kWh, the production lost due to curtailment was 21780739 kWh which after 97% availability and 2% line loss becomes 20704770 kWh. Due to the many curtailments at the site this program takes a lot of time (today it ran for 2 hours). Mark
