Sydney CBD solar farm to cut carbon emissions by 2,000 tonnes a year

The International Convention Centre Sydney (ICC Sydney) is set to introduce a solar farm atop its rooftop, comprising 4,500 photovoltaic panels. This solar farm will be the largest in any city centre across the Southern Hemisphere. Upon completion, the installation will significantly reduce carbon emissions by an estimated 2,000 tonnes per year, equivalent to the absorption capacity of a forest of around 100,000 mature trees.

The ICC Sydney already possessed some solar panels, but these older models were too heavy to be installed in certain areas. The newly installed, lighter panels will enable the centre to generate about 300 per cent more energy. Chris Jones, head of asset management at Capella Capital, the entity managing the facility, emphasized that the more efficient panels will result in a substantial increase in energy production.

Battery storage was not considered due to space constraints, and the grid was instead utilized to function as a synthetic battery. Power bills at the ICC Sydney currently stand at $1.8 million annually, and the centre is striving to minimize consumption by upgrading appliances like fridges. The existing solar panels will be donated to the Kindly Animal Sanctuary near Armidale for reuse, where they are expected to last another 10 to 15 years.

The ICC Sydney's solar farm aligns with the NSW government's initiative to create renewable energy zones (REZ) in major cities, with the Illawarra region currently serving as a testbed for urban-scale solar generation.
