Synergy Mid-west/South-west Non-residential Gas Supply®

Don't forget the small print

Prices current as at 1 July 2023. Prices are subject to change from time to time and other fees and charges may also apply. Prices listed include GST unless otherwise stated. Synergy calculates its tariffs to four decimal places. Electricity is charged in cents per ‘unit’ unless otherwise specified. A ‘unit’ is one kilowatt-hour (kWh).
If your supply address is located in a suburb where Advanced Metering Infrastructure (AMI) is available, to be eligible for the Synergy Business Time of Use® (R1) tariff you must have an Advanced Meter. If AMI is not currently available in your suburb but becomes available at any time in the future, you will be required to upgrade your meter to an Advanced Meter to remain eligible for this plan. Customers on this plan who elect to ‘opt-out’ of AMI and do not upgrade their meter will be reverted to the Synergy Business Plan ( L1).

What you need to know

The Mid-West/South-West gas tariff is a Government regulated energy tariff with no fixed term giving you flexibility and control over your business's energy expenditure. To be eligible for this plan your business needs to use over 180GJ per year (which is approximately $6,400).
