The NSW Energy Savings Scheme (ESS) is driving energy efficiency upgrades in NSW by providing financial incentives to make implementation more affordable and attractive.

It is administered and regulated in accordance with the ESS Savings Scheme Rule 2009 (or the ESS Rule) by the Independent Pricing and Regulation Tribunal of NSW (IPART).
