Hi Pam,
It is possible to use the Library Editor to add you own entries to any of SAM's libraries, including the TOD factor library. Hopefully the
instructions in Help
are enough to get you started. The TOD factors library is called "TOU Utility Rates."
Incidentally, we are planning an overhaul of SAM's library management system that will replace the current library format with simple comma-separated format that is easy to edit in a spreadsheet program. Stay tuned for that late this year.
Best regards,
Paul.
