Australian NEM regions ranked by maximum operational demand; MW, Q4 2025.
The five National Electricity Market regions are ranked by maximum operational demand in Q4 2025. All values use the same AEMO definition and megawatt basis, measuring peak regional demand rather than annual electricity consumption. New South Wales ranks first at 13,022 MW, followed by Queensland at 10,373 MW. Tasmania records the lowest maximum demand at 1,336 MW, about one-tenth of the New South Wales peak.
| Rank | Entry | Value | Period |

| 1 | New South Wales | 13K | Q4 2025 |
| 2 | Queensland | 10.4K | Q4 2025 |
| 3 | Victoria | 8.2K | Q4 2025 |

Evidence: Supports the maximum operational demand values for all five NEM regions.
The comparison covers the five mainland and Tasmanian NEM regions.
The maximum operational demand value was selected for each NEM region from the same AEMO Q4 2025 quarterly publication and ranked from highest to lowest.
Every row uses one AEMO quarterly publication, one definition and one unit basis.
