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.
Making regular updates to the Energy Savings Scheme Rule and Regulation is needed to ensure their effectiveness in helping reduce NSW’s emissions and achieving net zero by 2050.
Learn more about the current Energy Savings Scheme Rule, which commenced in June 2024.
