Questions and discussions about managing your energy usage and saving money
In NSW ,the hours are:
Weekdays:
Off peak 2200 to 0700
Shoulder 0700 to 1400
Peak 1400 to 2000
Shoulder 2000 to 2200
Weekends and Public Holidays
Off-peak 2200 to 0700
Shoulder 0700 to 2200 (ie no Peak)
For other States, I can't help you. The easiest way to find out is to get comfortable in your armchair and then actually ring AGL on 131-245 (I agree, the web-site is dire when it comes to looking for actual hard information.)
Note that AGL has some plans that are offered either with Time Of Use or with a flat usage charge. You may need to ask them to confirm if that is the case with Solar Saver, and ask which Plan they have put you on.
