Why should you compare energy plans?

The simple answer is that shopping around can save you on your energy bills. If you don't compare, you won't know whether or not there's any provider offering cheaper prices.

For example, there's a $1320 annual price difference between the cheapest and most expensive single rate electricity plans in our database.

Some other reasons to compare include:

• Discounts and other benefits included on an energy plan tend to last 12 months at most.
• If you don't negotiate new rates once your benefit period is up, your provider could move you to a more expensive plan.
• You're moving home. There's a chance your current provider may not offer the cheapest rates at the new address.
• Your energy provider has told you that prices are going up.

How do I choose the right electricity or gas provider in SA?

When comparing electricity or gas plans from different providers in SA, you'll want to keep some key information in mind:

• Guaranteed discounts: These can last for up to 12 months. Look for plans that offer the largest guaranteed discount. For electricity, the discount is compared to the reference price set by the Australian Energy Regulator every year on 1 July. Always aim for a plan that's lower than this reference price. The difference is shown as a percentage, making it easier for households to compare plans.

• Usage rate and supply charge: You can also compare plans by looking at the usage rate and supply charge. Usage rates determine how much you'll pay for each unit of energy used. Supply charges are what you pay daily for having your home connected with electricity and gas.

• Sign-up deals and extra perks: When comparing plans, it's worth looking beyond the yearly estimate or usage rates. Keep an eye out for for sign-up deals such as a $200 bill credit for new customers or loyalty program perks such bonus Everyday Rewards and Qantas Points. Depending on your habits, it might also be beneficial to choose a provider that lets you track your energy usage through a mobile app.

• Additional costs: Before signing up for a plan, make sure to read the terms and conditions for any extra charges, such as credit card fees or late payment fees.

Comparing plans and tariffs

How much you're charged for your energy use will depend on the type of tariff you're on.

Sometimes the energy distributor and subsequently the retailer may automatically put you on a one of the tariffs we'll be discussing in just a second.

Ulitmately though, you have the power to switch to one that better suits your energy needs.

Electricity tariffs

Households in SA have access to the following tariffs:

• Single rate: You will be charged a single rate for using electricity regardless of the time of day.
• Time of Use: Your usage rates will vary based on peak and off-peak hours. There may also be a separate rate for the 'shoulder period', which falls between peak and off-peak periods. A smart meter is required to be put on a Time of Use tariff.
• Demand: Some plans include a demand charge on top of a single rate or Time of Use tariff. The charge will be based on the highest point of power drawn from the grid during peak times at any given point in a season, year or month. It's done to take some load of the energy grid and deter people from using power at peak times.
• Controlled load: This applies to households with a separate meter for appliances such as electric hot water systems or pool pumps.
• Solar feed-in tariff: Households with rooftop solar installed can sign up to a plan that features a higher solar feed-in tariff than your normal electricity plan. This will determine how much money you can earn for exporting excess energy to the grid.

• Watch out for: There's a chance your energy distributor will automatically move you to a Time of Use or demand tariff. Keep an eye on your bill to see how you're being charged as these electricity contract may not benefit households that can't always control at what point during the day they use electricity the most.

Gas tariffs

Gas tariffs are a little less complex, but your choice is limited. A retailer will put you on either of the two tariffs we're about to list:

• • Flat rate: You'll be charged the same usage rate regardless of the time of day you're using gas, or how much of it you're using.
  • Block rate: Your usage rates will change based on consumption. For example, you'll be charged one rate for using 50MJ, another rate for the next 35MJ and maybe a different rate for the next block.
