AGL Business Essentials is available to business customers in areas where AGL operates as part of an ongoing Market Contract and has a 12-month Energy Plan Period. The rates under this plan are fixed and will not vary for the duration of the 12-month Energy Plan Period. These rates will differ from AGL's published variable rates and other fixed rates that AGL may offer from time to time. At the end of the 12-month Energy Plan Period, we may notify you of new rates or benefits that will subsequently apply to you. If we don't notify you, your Energy Plan will continue to apply for a further Energy Plan Period. Although the rates are fixed, other charges may vary with notice to you.
