Crown Trigeneration Replacement Project (Revoked)

Crown Trigeneration Replacement Project (Revoked) was an industrial energy efficiency project located at the Crown Melbourne entertainment complex in Southbank, directly across the Yarra River from the Melbourne CBD. Registered in August 2018, the project operated within an ultra-urban, high-density commercial zone rather than the agricultural settings typical of many Australian carbon projects. The project was voluntarily revoked in November 2023.

The project operated under the Industrial and Commercial Emissions Reduction (ICER) methodology (previously the Industrial Electricity and Fuel Efficiency method). This methodology credits activities that reduce emissions intensity by upgrading equipment or switching fuels. Specifically, this project involved replacing or upgrading a trigeneration system, a facility that simultaneously produces electricity, heating, and cooling from a single fuel source (typically natural gas). By generating electricity on-site and capturing waste heat for hot water and absorption chilling, the system displaced more carbon-intensive grid electricity.

While the "land use" is strictly commercial/industrial, the underlying environment of the Southbank and Yarra Delta region is characterized by Quaternary alluvial silt and Coode Island Silt, a distinct, dark grey silty clay known for its compressibility. The region experiences a temperate oceanic climate with uniform rainfall averaging approximately 600mm to 650mm annually.

A notable aspect of this project is its revocation under "Section 30 of the CFI Rule," which indicates a voluntary revocation by the proponent rather than a compliance enforcement action. This is common when projects reach the end of their crediting capability, undergo significant operational changes, or transition to different reporting frameworks. Historical industry reports indicate that Crown’s original trigeneration infrastructure (utilizing Caterpillar engines) was capable of reducing site emissions by approximately 25,000 tonnes of CO2-e per year while providing critical backup power security for the complex.
