Greenhouse gas emissions intensity of the NSW electricity grid
AEMO Services has awarded 6 Long-Term Energy Service Agreements for firming infrastructure, 3 firming supply agreements and 3 demand response agreements.
As the default regulator under Part 12 of the Electricity Infrastructure Investment Regulation 2021, we have a role to ensure that facilities which hold a firming supply agreement meet their emission intensity obligations under the Regulation. The 6 facilities are expected to be operational from December 2025. Once operational, the EPA must calculate the greenhouse gas emissions intensities of the NSW grid and the 3 firming supply facilities using the formulas prescribed in the Regulation.
We will also need to determine if firming infrastructure operators must purchase and surrender offset units to meet their obligations. Prior to 2036, offsets will be needed if the emissions intensity of a facility is higher than that of the NSW grid for each calendar year. After 2036, firming infrastructure operators must achieve net zero by purchasing offset units equal to their facility’s scope 1 emissions.
The table below shows the greenhouse gas emissions intensity for the NSW electricity grid for 2021 and 2022. We will publish the NSW grid intensity and the emissions intensities of facilities each year. See our guideline (PDF 1MB) for more information on our responsibilities and how we will fulfil them.
NSW Grid greenhouse gas emissions intensity
Calendar year | NSW grid GHG emissions intensity (tCO2-e per MWh) |
---|---|
2022 | 0.66 |
2021 | 0.69 |
*National Greenhouse and Energy Reporting data is reported on financial year. The EPA averages this data reported from the relevant financial years to calculate emissions intensity for a calendar year.
