We continue to reduce carbon emissions and are committed to clear emission reduction targets.
CO2-e emission reduction targets are:
8% reduction by end FY2024 (44% excluding line losses); and 17% reduction by FY2030*
Our carbon footprint is 1 million tonnes of CO2-e per annum and these targets are expected to remove 83,700 tonnes of CO2-e by mid-2024, equal to taking approximately 17,100 cars off the road. We know that improving our energy efficiency and reducing our carbon footprint is another way we can reduce costs and address climate change - which will benefit our customers and the environment.
Ausgrid is committed to achieving its carbon emissions reduction targets as part of our Climate Action efforts in support of the UN Sustainable Development Goals.
In managing and monitoring our carbon emissions, we capture data on our annual performance across our full range of emissions and report this information for compliance with the Federal Government’s National Greenhouse and Energy Reporting scheme.
Our Emissions Performance Report communicates information on our carbon emissions, key factors that are influencing our performance, and measures our progress in achieving our emissions reduction targets.
Ausgrid also has a role to play in supporting Australia’s transition to a clean energy future. We have a range of initiatives to reduce our carbon emissions, including:
Currently endorsed and underway
Apart from CO2, the gas that most impacts Ausgrid is sulphur hexafluoride (SF6) used as an insulating gas in electrical equipment and it has 22,800 times more global warming potential than CO2. We are working to better understand alternatives to SF6 and improve the management of our existing stocks of SF6 on our network.
|CO2-e (carbon dioxide equivalent) emissions are a mixture of greenhouse gases such as carbon dioxide, methane, nitrous oxide, sulphur hexafluoride and perfluorocarbons.|
*Our emissions targets are calculated from the baseline year of FY2017 to capture initiatives implemented since the transition from government to private ownership.
** ‘Line losses’ is the energy lost in the transmission and distribution of electricity. The cost to reduce our level of ‘line loss (approximately 4%) is prohibitive. As the generation of clean energy increases and decarbonises the wholesale energy supply, the carbon footprint of line losses will decrease. This change will reduce Ausgrid’s carbon footprint.
Distribution network losses are the difference between the electrical energy that enters our distribution network and the energy that is delivered to our end customer. They are the unavoidable consequence of transferring electricity across the network but can be minimised using appropriate technologies and assets.
Line losses are inherent to the distribution of electricity and cannot be eliminated. As energy passes through our network, a small proportion of this is lost as heat during the transportation. To minimise energy costs to consumers, where practical and cost effective, we undertake activities to reduce line these losses. Our line losses on average are about 4% of the energy we deliver.
As the proportion of renewable energy that we distribute increases as a result of decarbonisation of energy generation in NSW, this will lower the carbon footprint of our line losses.
