Improving energy use

Operating water and sewerage treatment infrastructure 24/7 to provide essential services to the community uses a lot of electricity – around 35,000 megawatt-hours (MWh) in total each year! 

So we’re in the process of delivering energy efficiency programs to reduce usage and increase renewable generation. In March 2018, the Investment Review Committee (IRC) approved the execution of Icon Water’s solar Photovoltaic (PV) project (CX11222). The project involved the installation of 2.29 MW of solar PV across five sites, including: 

• Lower Molonglo Water Quality Control Centre
• Uriarra Sewage Treatment Plant
• Stromlo Water Treatment Plant
• Cotter Dam
• Mitchell office

These solar PV arrays will generate 4,155 MWh of electricity each year to power Icon Water’s assets and reduce our impact to the electricity grid by around 12%. This will decrease our annual greenhouse gas emissions by around 3,500 tonnes, which is equivalent to taking over 700 cars off the road!

Once all solar PV systems are commissioned, the first year of operation is expected offset grid electricity usage by over $600,000. In addition, Large-scale Generation Certificates (LGCs) that will be created from the two larger solar PV systems can be sold to the market to generate additional revenue.
At December 2019, all of the solar PV systems were energised, except for one of the two systems at the Lower Molonglo Water Quality Control Centre which is under construction.

We’re always looking at ways to reduce our energy consumption and explore renewable energy options. For any enquiries talk to us on or 02 6248 3111.
