Electricity use in Adelaide by season
Winter is the heaviest quarter in Adelaide, not summer. Reverse-cycle heating runs for longer across June, July and August than air conditioning does over a hot but short summer.
This is why a single "average bill" figure is close to useless on its own. The same household, in the same house, with the same habits, produces very different bills depending on which three months the bill covers.
| Household | Summer | Autumn | Winter | Spring |
|---|---|---|---|---|
| 1 person | 687 | 704 | 894 | 651 |
| 2 people | 1,225 | 1,188 | 1,526 | 1,107 |
| 3 people | 1,460 | 1,442 | 1,846 | 1,354 |
| 4 people | 1,740 | 1,652 | 2,090 | 1,552 |
| 5 or more people | 2,080 | 2,019 | 2,688 | 1,932 |

What makes Adelaide different
Adelaide has its own benchmark rather than sharing one with the rest of the warm temperate zone, because the South Australian government asked for the state to be broken into ten local areas. That makes the Adelaide figures the most locally specific in the country.
