You should have 4 tariffs called - Peak, Off-Peak, Normal, Valley (1=Peak 2=Off-Peak 3=Normal 4=Valley) - Then you should have 14x 24hour Schedules 1-14. Each schedule you can link to a season for example you have 2 seasons one from September - May the other from June - August. Let assume weekend are not charged at at different rate for now.
In the software you would link the season to a schedule something like this (DD-MM scheduleNumber) 01-06 1 (1 June uses Schedule number 1), 01-09 2 (1 September uses Schedule number 2)
Let assume the Schedule for season 1 look like this Schedule.JPG
Schedule number 1 (linked to Season 1 above): It should have 14 time slots (HH:MM ID=Tariff to uses 1-4)
slot1: 00:00 2 slot2: 05:00 1 slot3: 07:00 4 slot4: 12:00 1 slot5: 17:00 4 slot:6 20:00 1 slot7: 21:00 2 (time slot 8-14 not used)
Let assume the Schedule for season 2 look like this Schedule1.JPG
Schedule number 2 (linked to Season 2 above): It should have 14 time slots (HH:MM ID=Tariff to uses 1-4)
slot1: 00:00 2 slot2: 06:00 1 slot3: 08:00 4 slot4: 13:00 1 slot5: 18:00 4 slot6: 21:00 1 slot7: 21:00 2 (time slot 8-14 not used)

It should be possible to active the weekend scheduler for Sunday, Saturday or Both separately. e.g Saturday and Sunday is active you should be able to link Saturday to one of the schedules 1-14 and link Sunday to one of the schedules 1-14 similar to the above.
If holiday scheduling is enabled then this should also be linked to a schedule 1-14 similar to the above.
When you run this on a kWh point it should give you the totals for the current month or any past month for kWh consumed in Peak, Off-Peak, Normal and Valley time periods.
Does this make sense?
