Annual electric load profile data start time

Hi All,

I have a full year of kWh load data (8076 readings) for the year 2015. The first date/time stamp is 1/1/15 01:00 and last 31/12/15 24:00.

I notice when the data is read in to SAM that the first data point from 1/1/15 01:00 is actually shifted back to 31/12/14 23:00. Should this be expected?

Thanks,
Robert

Dear Robert,
For hourly data, SAM expects the first time stamp to be for the hour that begins at 12:00 am January 1, and the last one to be for the hour that begins at 11:00 pm December 31.
Where in SAM are you seeing the time shift? Would you mind [url=mailto:sam.support@nrel.gov?subject=Time%20Shift%20Weather%20File t=_self]emailing me[/url] a copy of your weather file?
Best regards,

Paul.
