Last month Brisbane had a couple of distinctly hot days. Sure, our summers are already hot compared to many places, but those two days stood out from the rest. Energex put out this chart showing what it did to electricity demand, as fridges worked harder and air conditioners were turned on across the city.
The energy use on those two days was 1000 megawatts above anything else for the previous two weeks. This is one of the main drivers of electricity price rises - paying for energy infrastructure that sits idle for most of the time. By conserving energy, particularly with the items that are responsible for these peaks, we can reduce the need to spend millions on all that extra capacity. This helps keep future prices down, as well as saving money on our own electricity bill.
