Economy tariffs
Economy tariffs are great for appliances like hot water systems and pool pumps that don't need a constant supply of power.
They're cheaper because the supply on these tariffs is interruptible and Ergon Energy Network controls the times when power is available. The times of day this will occur may change from day to day and vary in duration.
For appliances that you need power to be available on a constant basis or at a regular time each day, you may prefer to connect them to Tariff 11 which gives you power 24/7.
A licensed electrical contractor will be able to assist you with this.
Economy tariffs must be used in conjunction with a primary tariff at the same address (and NMI) and can't be used to run an entire household or business, except for business customers accessing primary controlled load tariffs (Tariff 34 or 60A) on approval from the distribution business.
