Energy Savings Scheme changes

The Energy Savings Scheme (ESS) is NSW’s largest energy-efficiency program, established in 2009 under the NSW Electricity Supply Act 1995. The Energy Savings Scheme will run until 2050, in line with NSW’s net zero goals.

We need to make regular updates to the Energy Savings Scheme Rule and Regulation to ensure they are effective, to reduce NSW’s emissions and achieve net zero by 2050.
