Corporations registered under the National Greenhouse and Energy Reporting Act 2007 (NGER Act) are required to report greenhouse gas emissions and energy production and consumption to us by 31 October each year.
By 28 February the following year, we publish a point-in-time extract of scope 1 emissions, scope 2 emissions and energy production data specific to the electricity sector for the previous financial year.
Unlike the corporate emissions and energy data set, which is published at a controlling corporation level, the electricity generation sector emissions and production tables below are published at a designated generation facility level. This includes primary fuel source, emissions intensity and grid connection for each generator. We also publish aggregated emissions and production for the entire sector.
Designated generation facility data 2024–25

Electricity sector emissions and production data 2024–25

The CER publishes total electricity generation and emissions data to help with tracking the sectoral baseline as set under the Safeguard Mechanism.
Under the Safeguard Mechanism, a sectoral baseline applies collectively to grid-connected electricity generators. Under the National Greenhouse and Energy Reporting (Safeguard Mechanism) Rule 2015 the sectoral baseline is set at 198 million tonnes carbon dioxide equivalent (Mt CO2-e). If the sectoral baseline is exceeded collectively by grid-connected generators, it will no longer apply, and individual baselines will apply to generators.
In 2024–25, total reported scope 1 emissions from grid-connected generators were 133.7 Mt CO2-e.
| Electricity production (GJ) | Electricity production (MWh) | Scope 1 (t CO2-e) | Scope 2 (t CO2-e) | Total emissions (t CO2-e) | |
|---|---|---|---|---|---|
| Grand total | 791,673,155 | 219,909,212 | 135,821,941 | 2,666,944 | 138,488,885 |
| Grid connected total | 775,274,555 | 215,354,045 | 133,700,664 | 2,666,614 | 136,367,278 |
