These days, time-of-use rates—which have varying pricing throughout the day—are growing more and more popular, making it increasingly crucial to determine exactly when Australians use electricity.
People who are willing to monitor their energy use closely can save money, but others who are caught off guard or live in less energy-efficient homes may suffer more.
In what ways might time-of-use rates help you save money, and what does the research indicate about their impact on households?
Electricity usage timing
Unlike flat rate plans, which have a single price, time-of-use power plans have energy prices that change during the day.
Retailers and distribution areas have different plans, but generally speaking, there are three different rates: a peak price, an off-peak price, and a shoulder price, which is usually in the middle.
When there is less demand on the grid, such overnight, the off-peak price is the lowest and usually less expensive than what is charged on a flat rate.
According to Lee White, a senior lecturer at the University of Sydney, this is in contrast to peak rates, which are often charged throughout the evening between 5 and 8 p.m., when demand surges.
When everyone gets home from work and switches on their heating or begins cooking, White explained, the evening peaks are more expensive, driven by the need to turn on gas peaking plants.
In general, electricity with time-of-use tariffs is more costly in the evening.
Additionally, there is a shoulder rate, which is often levied throughout the day and may be marginally less expensive than flat rate rates. This indicates that there is currently more electricity available in the system.
Time-of-use tariffs are intended to encourage customers to use more electricity when it is less expensive to generate and to use less when there is a high demand on the grid.
Energy efficiency and transparency are crucial.
However, White noted that consumers may find it challenging to alter their consumption and comprehend what costs are being charged at what times, so the details are crucial.
Additionally, White's recent study emphasized the significance of residential energy efficiency for time-of-use rates, with consumers in less efficient properties compromising comfort in order to lower their use during peak hours.
Your home's efficiency determines how much heating you need to utilize to make it comfortable, he explained.
In an efficient home, you can pre-heat or pre-cool, but when you turn on your heat, you can have an even more unmanageable peak.
To make matters worse, there have been alarming allegations in recent months that some families are unaware that they are subject to time-of-use tariffs, despite the fact that this means their bills are significantly higher.
The Australian Competition and Consumer Commission (ACCC) recently brought attention to the reports, which White says are "very disturbing."
We know there is a financial incentive to promote behavioral change, but you can not change your behavior if you do not realize you are on that rate, White stated.
