Typically, your bill will include supply charges and usage charges for electricity and gas if you have it. Supply charges are a fixed price, which you pay for connecting your house to the electricity or gas distribution network, regardless of how much energy you use. As the name suggests, usage charges are calculated based on your household or business’s electricity or gas consumption. You can check your most recent energy bill to find out the rates you’re currently paying for the energy consumed in your household or business.
Both households and businesses can access different types of electricity tariffs, which affects the usage charges they pay:
- Single rate tariffs require you to pay the same rate for buying electricity irrespective of when you operate your electrical appliances.
- Time-of-use tariffs apply a different rate depending on whether you use more electricity during peak hours or off-peak or shoulder hours.
- Controlled load tariffs apply to electricity usage for a single appliance or equipment.
- Solar feed-in tariffs are the credit you receive for supplying solar energy not used in your home into the grid.
Similarly, usage charges for a gas connection can vary between seasons in some places. You could end up paying more for gas usage in winter than in summer if your energy provider charges seasonal rates.
Understanding supply and usage tariffs can help you choose an energy plan that’s better suited to your requirements. For instance, if you expect to use less electricity or gas, you could choose an energy plan with a lower supply cost rather than a lower usage cost. Since your usage charges are likely to be on the lower side, you may save money by opting for a lower supply cost. On the other hand, if your home has several electrical appliances that are used daily, you may be better off with an energy plan that offers more flexibility in choosing electricity tariffs.
Most electricity and gas providers in NSW can change the tariff at any time during a billing period unless you’re on a fixed-rate contract. However, your energy supplier needs to give you a written notification of the change, usually sent with the first bill after the rate change becomes effective. This statement should specify your consumption and the charges applied at the old and new rates. If you have any questions regarding the change of rates, you should contact your energy supplier as soon as possible. If you find the new tariffs unaffordable or would like to find a better deal, compare the rates offered by the best energy providers in NSW. Once you have information on other offers in the market, you may be able to get your current energy provider to negotiate a better deal. This will mean you won’t need to switch providers.
Energy prices also differ based on the distribution network. There are three distribution networks for gas and electricity supply in NSW:
- Ausgrid covers the wider Sydney area up to Newcastle, inland to Muswellbrook, Barry and Merriwa.
- Endeavour Energy neighbours Ausgrid and covers Sydney’s greater west, Southern Highlands, Illawarra, Wollongong, the South Coast of NSW and the Blue Mountains.
- Essential Energy's distribution network includes the remainder of NSW and parts of south-west QLD.
